The Re-Emergent Interdisciplinary Nature of Scholarship

One of the complaints about scholarship these days, especially in the humanities but also in the natural sciences, is that each discipline has become so specialized, that it has become irrelevant to those on the outside. Young scholars in PhD programs are continually pushed to the marginalia in the search for new and original topics, and the dissertations they churn out are frequently so obscure and specific that nobody would read them except the author and their board.

My goal in this post is not to complain about over-specialization in scholarship but rather to suggest that over-specialization is not the way of the future. David Brooks’ op-ed in the New York Times this week, entitled “The Young and the Neuro,” addresses the necessarily-interdisciplinary nature of contemporary research being conducted in the humanities, and especially in cognitive neuroscience, which fuses the fields of bioetechnology, psychology, economics, as well as political science and ethics. Scholars involved in this emergent field are actually transversing disciplines, all in the hopes of trying to figure out how and why people interact in the way that they do.

The new interdisciplinary nature of such scholarship is a reaction against the reductionism we saw in the earlier part of the century, especially in the wake of new knowledge about genetics. A funny side note: in yesterday’s NYTimes crossword puzzle, one of the clues (33 across) was “essence of a person, one might say.” Not to spoil it for you, but the answer is DNA.

The research Mr. Brooks discusses challenges this notion that DNA actually is the essence of a person. People like Christopher Hitchens and Richard Dawkins and E.O. Wilson wanted to use genetics to explain the essence of all human behavior. Ethics, once considered a branch of philosophy, entered into the natural sciences as scientists hypothesized and rapidly worked to confirm that one’s genetic constitution could explain why you as a person behaved the way you did. This field became known as sociobiology–the systematic study of the biological basis of all forms of behavior.

If the sociobiologists would have stuck to ethics, they would not have ruffled very many feathers. But sociobiologists also had to attempt to illustrate how genetics could even explain the great metaphysical questions faced by humankind such as the nature of the soul and the existence of God. What happened in the wake of such books like The God Delusion was a widespread religious reaction against science, especially science that extolled genetics as a causal mechanism or used the dreaded word “evolution.” This religious antithesis to the new work in biology, genetics, and evolution became another form of reductionism. Instead of using science to explain everything, the “theologians” and preachers and ordinary believers wanted to use God to explain everything.

Here is what both sides missed. Different fields explain different phenomena and answer different pressing questions raised by human beings. This was something Aquinas (drawing on the Greek heritage of Aristotle) recognized in distinguishing the practical from the speculative intellect. The practical intellect deals with the natural world, the world that is contingent, subject to decay and change and evolution. The practical intellect deals with sense data derived from sensuous consciousness, that is, with this particular human being, this particular triangle, this particular action.

The speculative intellect is concerned not with the contingent, but with the necessary, the universal, the unchanging. The speculative intellect is concerned with the immaterial. It wants to know not “this particular triangle” but rather, what is the essence of “triangle?” What is the universal form that makes particular triangles come into being? The speculative intellect is not concerned with this particular action, but rather with the question of causation–what are the universal forces that causes anything at all to happen?

The practical intellect deals with what Aristotle called the practical sciences: physics, ethics, politics. The speculative intellect deals with the mother of all science: metaphysics (literally, “above or beyond the physics.”) Aquinas recognized in light of his theological preoccupations that even this neat division was not truly in accordance with reality with the recognition that theology was both speculative (metaphysical) and practical (ethical and political). That is, our study of God is primarily speculative but imminently practical. Theology is speculative because it deals principally with divine things which are immaterial, but secondarily practical because it is concerned with human acts insofar as these acts lead the person to beatitude. So even theology, the premier metaphysical pursuit becomes interdisciplinary in Aquinas’ work. The larger part of the Summa theologiae (“sum of theology”) deals with practical matters, what we would now call ethics.

But Aquinas’ ethics are a theological, and hence, interdisciplinary ethics. His ethics are most certainly theological in the sense that all human acts must be properly considered as part of the life in the spirit. Charity, the most important theological virtue, is the form and mother not just of the theological virtues, but of all the virtues, including the human or moral virtues of prudence, justice, temperance, and fortitude. Thomas’ sum of theology shows how biology, anthropology, politics, ethics, economics, metaphysics, and theology are interwoven, each answering different particular questions in order to draw the really important conclusions concerning why we (humans) are here on this earth, what we are supposed to be doing while we are here, and where we are ultimately meant to end up.

In Aquinas’ day, he could be a theologian, an ethicist, a political scientist, an economist, and an anthropologist, but such “renaissance men” were thought to have been long-extinct in the contemporary period in light of the increasing specialization of each of the disciplines. We assumed that to really know anything in the wake of the proliferation of knowledge that followed the modern scientific, industrial, and technological revolutions, you had to be a specialist.

What Brooks’ article indicates to my Thomistic eyes is that we are beginning to re-recognize the important ways in which the practical and speculative concerns overlap, the dangers of reductionism, and the importance of interdisciplinary pursuits in drawing the right sort of conclusions about the questions we are asking. As Brooks points out, we now know the important influence that genetics has on our behavior. But we are beginning to recognize also how complementary processes of social interactions and culture influences genetics and physiology. He writes,

All of these studies are baby steps in a long conversation, and young academics are properly circumspect about drawing broad conclusions. But eventually their work could give us a clearer picture of what we mean by fuzzy words like ‘culture.’ It could also fill a hole in our understanding of ourselves. Economists, political scientists and policy makers treat humans as ultrarational creatures because they can’t define and systematize the emotions. This work is getting us closer to that. . .

The hard sciences are interpenetrating the social sciences. This isn’t dehumanizing. It shines attention on the things poets have traditionally cared about: the power of human attachments. It may even help policy wonks someday see people as they really are.

The challenge faced by young scholars like myself is no longer how to get my questions and my language specific enough to generate a new idea. Rather, young scholars are faced with the new challenge of how to gain a broad enough base of knowledge to re-ask the really old questions without dabbling too much, or drawing conclusions that are too broad to actually be meaningful.

My own dissertation asks how we can integrate a moral theological discourse into the already-interdisciplinary discourse about eating disorders, that is, anorexia nervosa and bulimia nervosa. Researchers have already acknowledged that eating disorders are physiological, biomedical, psychological, and sociological disorders; I argue that they are also moral disorders. So if you want to really know why people have eating disorders and what can be done about it, you need more that psychology, biomedicine, and sociology. You also need ethics, metaphysics, and yes, even theology.

A Thomistic Response to N.T. Wright on Metaphysics, Trinitarian Formulas, and the Historical Jesus

In Chapter 4 of Scripture and Metaphysics, Matthew Levering takes on N.T. Wright who argues that traditional Western Trinitarian theology bypasses the narrative account of Scripture especially regarding the historical Jesus, and instead presents a fundamental non-narrative Trinitarian theology which “approache[es] the Christological question by assuming this [ontological] view of god and then fitting Jesus into it” (Wright, “Jesus and the Identity of God,” 54).

Wright begins his essay with a personal anecdote of talking to students who claim to not believe in god. Wright probes them to explain “which god they don’t believe in” and determines that when students say this, what they mean is that they do not believe in a god who sits on high, looking down and casting out judgment, what Wright calls the “spy-in-the-sky.” To these students, Wright responds that he does not believe in such a god either, but rather, believes in the God that is revealed in the historical Jesus of Nazareth.

Wright’s point is that we need historical studies of Jesus because it is all too easy to create an idol of Jesus, a heavenly, perfect, sinless, and non-Jewish Jesus “who wanders round with a faraway look, listening to the music of the angels, remembering the time when he was sitting up in heaven with the other members of Trinity, having angels bring him bananas on golden dishes.” Rather than starting off with the Orthodox, post-Nicaean and post-Chalcedonian Jesus as the second person of the Trinity (what Wright calls the kyriarchal portrait of God), Wright argues that we need to start with the historical Jesus who reveals to us not a creedal formula, but rather, the Old Testament God of Israel:

In Jesus himself, I suggest we see the biblical portrait of YHWH come to life: the loving God, rolling up his sleeves (Isa 52:10) to do in person the job that no one else could do, the creator God giving new life the God who works through his created world and supremely through his human creatures, the faithful God dwelling in the midst of his people, the stern and tender God relentlessly opposed to all that destroys or distorts the good creation, and especially human beings, but recklessly loving all those in need and distress. “He shall feed his flock like a shepherd; he shall carry the lambs in his arms; and gently lead those that are with young” (Isa 40:11). It is the OT portrait of YHWH, but it fits Jesus like a glove.

In this chapter, Levering wants to save Aquinas from the implicit criticism of people like Wright, namely, that his conception of Jesus is sterile and formulaic, and completely detached from the Jesus as revealed in Scripture. Instead, Levering claims that Aquinas rejects the kyriarchal portrait of God just as strongly as Wright does. He cites the Tertia Pars, QQ. 46, art. 3. where Aquinas asks whether there was a more suitable way of delivering the human race than by Christ’s passion. In the first objection, alluding to St. Anselm’s Cur Deus Homo, Aquinas states that God could have liberated humankind solely by His Divine Will! This could have not only spared the life of the incarnate son of God but would have more suitably revealed God’s superior power.

But Aquinas rejects the mighty display of God’s power as more suitable than the Passion (as does Wright) on the grounds that Christ’s passion teaches us about the God who saves us: “In the first place, man knows thereby how much god loves him, and is thereby stirred to love him in return, and therein lies the perfection of human salvation” (IIIa, Q. 46, art. 3). As Levering writes:

Christ’s Paschal mystery reveals to human kind the extraordinary depth of God’s love. Without Christ’s passion, humankind would not have known the superabundance of God’s love. The Paschal mystery reveals the Trinity (God-in-himself) in terms of a wisdom of wondrous love,, to the point of the Son of God giving his own life for the salvation of sinners, that is, for the salvation of those who by pride had cut themselves off from God” (Levering 134).

Aquinas does not give us the “disembodied theological cipher” which Wright wants to counter with the historical Jesus, but rather, to use Wright’s own words, “the Jesus whose body was killed as the revelation of the love of God and raised to new life.”

Aquinas gives another reason that Christ’s bloody passion was more fitting than a mighty display of God’s power neatly accomplishing the same task. That is, by his passion, Christ “set us an example of obedience, humility, constancy, justice, and the other virtues displayed in the Passion which are requisite for man’s salvation. Hence it is written (I Peter 2:21): ‘Christ also suffered for us, leaving you an example that you should follow in His steps” (IIIa, Q. 46, art. 3). Levering’s point is this, that like Wright, Aquinas appeals to the cross and the scriptural account of Jesus to dispel what Wright calls the “kyriarchal” or aloof, uncaring and philosophically formulaic God. But unlike Wright wants to argue that his scriptural and historical account of Jesus reveals a God of superabundant love, of humility, and of personified wisdom, as opposed to the philosophical accounts of God that his students reject, Aquinas uses philosophy to probe the depths of this mystery further. Namely, Aquinas draws a Trinitarian conclusion.

Jesus, Aquinas argues, was able to endure such suffering (which we have already established is intended to suitably reveal the intimate love of God that God is willing to suffer with and for God’s people) because of intimate knowledge of the Father. In suffering, and suffering without sin, for the sins of others, Jesus had full knowledge of Father, which gave Jesus the ability to suffer the most profound sorrow for sin out of the love which is manifest in the Father. As Levering writes, “the Father inspired Christ’s human will with this perfect charity by infusing Christ’s humanity with the fullness of the grace of the Holy Spirit. In Christ’s passion, one thus sees manifested the incarnate Son’s obedience to the Father through the Holy Spirit. The Paschal mystery of Jesus Christ reveals God’s wisdom and love in Trinitrarian form” (136).

For Aquinas, the scriptural Jesus, and especially the scriptural account of Jesus’ death reveals the Father as the one who sends the Son as the Father’s Word of love for the world, reveals the incarnate Son who is God’s perfect Word in the world, and reveals the Holy Spirit who enables the incarnate Son to suffer with supernaturally-inspired love. That is, for Aquinas, it is not the study of metaphysics, though metaphysics certainly helps, and not the study of creeds, though creeds are important, but precisely the study of Scripture and especially the Passion which reveals the Trinity.

We see the central and foundational importance of scripture in Aquinas’ Trinitarian formulas elsewhere, specifically in his commentary on John. Commenting on John 5:20, Aquinas writes that “because the Father perfectly loves the Son, this is a sign that the Father has shown him everything and has communicated to him his very own power and nature” (Super Ioan. 5, lect. 3, no. 753). Because the Father gives the Son everything he has, the Son is the perfect image of the Father (Hebrews 1:3, Colossians 1:15) or as Aquinas reflects using metaphysical language “since likeness is a cause of love (for every animal loves its like), wherever a perfect likeness of God is found, there also is found a perfect love of God” (Super Ioan 5, lect. 3, no. 753). Just as the Father bets the Son by absolute self-gift, so too the Son, in order to reveal the Father, must give himself completely.” Hence, we get the Passion.

This is not a way of ignoring the God of Israel which Jesus reveals perfectly through his earthly life (as Wright wants to argue); it is, however, a fuller revelation of the God of Israel. Levering writes, “Before Christ’s coming, the people of Israel knew God the father, but they only knew him as father in the sense of Creator, and as the one and only God. Christ’s disciples, on the other hand, are able to know Father by faith (by the grace of the Holy Spirit) as the Father of the only-begotten son” (139). Aquinas cites John 5:36 on this point: “The very works which m Father has given me to perform—those works that I myself perform—they bear witness to me that the Father sent me.” According to Aquinas, by the power of the Holy Spirit, Jesus, by revealing himself through his works, also reveals the Father. This is the basis of Trinitarian formulas—the works of Jesus as related by Scripture.

Wright wants to say that if we really study the Jesus as revealed in Scripture, we will not get at a creedal Trinitarian formula. The real Jesus and the Second Person of the Trinity have nothing to do with each other. He writes,

After fifteen years of serious historical Jesus study, I still say the creed ex animo; but I now mean something very different by it, not least by the word “god” itself. The portrait has been redrawn. At its heart we discover a human face, surrounded by a crown of thorns. God’s purpose for Israel has been completed. Salvation is of the Jews, and from the King of the Jews it has come. God’s covenant faithfulness has been revealed in the good news of Jesus, bringing salvation for the whole cosmos.

But for Aquinas, as Levering points out, it is precisely by studying this historical, earthly Jesus that we are taught, as Jesus taught his friends, about the Trinity. Jesus teaches us through his words and actions. On this, Aquinas would agree with Wright. But whereas Wright uses only historical and literary methods to understand this Jesus, Aquinas also integrates metaphysical methods to not only exegete the historical Jesus, but also to be conformed to true knowledge of the living God revealed in scripture. Metaphysical speculation does not, as Wright criticizes, lead to the construction of an aloof kyriarchal idol, but rather, seeks to illuminate the true meaning of scriptural narrative of the transcendent and immanent God revealed to Israel as YHWH. In short, metaphysical speculation, in addition to historical and literary methods of understanding, complement one another by instilling within the believer greater contemplative understanding of the mystery of the Trinity. Or as A.F. Gunten, O.P. remarks,

“The texts of Scripture invited [Aquinas] to undertake a philosophical study that bears its fruits. It then permits him to give a more precise interpretation of Scripture.”

Aquinas on God’s Knowledge

Jon Levenson writes in Creation and the Persistence of Evil: The Jewish Drama of Divine Omnipotence that three Christian theological errors have distorted the scriptural understanding of Israel’s God:

1. “the residue of the static Aristotelian conception of deity as perfect, unchanging being”
2. “the uncritical tendency to affirm the constancy of divine action;”
3. “the conversion of biblical creation theology into an affirmation of the goodness of whatever is.” (Levenson xxv).

This is the argument that Matthew Levering takes on in Chapter 3 of Scripture and Metaphysics, namely, that in light of Scripture’s numerous accounts of God’s capricious will e.g. Exodus 32, Jeremiah 18), incomplete knowledge (Genesis 18:21), and impotence to stop certain atrocious acts, how can Christian theology still hold that God is unchanging, omniscient, and omnipotent. Levering illustrates how Aquinas solves this problem through a creative interplay of Scriptural exegesis and metaphysical reflection. In this post, we will discuss Levenson’s argument that God is not omniscient as the metaphysicians claim that God is.

Levering first identifies three important aspects of Aquinas’ scriptural exegesis. The first is that Aquinas has a “whole-canon hermeneutic;” that is, he accepts on faith that the whole Bible contains God’s self-revelation. This means that Aquinas thinks that each passage which reveals something about God’s identity must be weighed against other relevant passages in order to understand the full meaning of these passages.

Second, Aquinas thinks that the images of God found in the biblical texts must be analyzed metaphysically in order to fully understand what the text is saying, and in order to avoid anthropomorphizing God. The third point is related to the second. That is, Aquinas believes that human language used to refer to God is analogical, meaning that words used to describe finite creatures like “good” or “wise” or “angry” cannot be fully and properly ascribed to God who is beyond human comprehension and human language. To see more on Aquinas’ use of analogical language to talk about God, check out this earlier post.

In seeking to understand God’s knowledge, Aquinas turns first to the relevant passages of Scripture, and then uses metaphysical speculation to investigate these revealed mysteries by establishing “their ontological, causal, and communicative structures, [thus enabling him as a theologian] to express judgments about the meaning of Scripture’s claims about God and human beings” (Levering 21; see Fides et Ratio no. 66).

Jon Levenson, influenced by process theology, doubts that God fully knows other creatures, arguing that this seems to contradict the image of God in scripture of God coming to know his creatures, whose free actions seem to frequently allude the knowledge of God. In investigating God’s knowledge, Aquinas begins with God’s perfection, citing Matthew 5:48: “Be perfect as your heavenly Father is also perfect.” Aquinas notes that “a thing is perfect in proportion to its state of actuality, because we call that perfect which lacks nothing of the mode of its perfection” (Ia, Q. 4, art. 1). What he means is that we use the word “perfect” analogically to describe the being of something.

A thing is perfect in so far as it exists the way that it is supposed to. A pen, for example, is perfect in so far as it fully exists as a pen is supposed to exist, writing smoothly, etc. Human beings, however, are more complicated than pens. There are lots of different ways that humans can be. Humans can be wise or unwise, they can be good or not good, they can be knowledgeable or lacking knowledge. Human beings are good or perfect (that is, achieve the fullness of their being) to the extent that they do the various things that human beings are supposed to do. One of the things that humans are supposed to do is “know things.” Thus, knowledge is one of the various perfections that we can ascribe to humans.

But humans exist or “have being” in a different way that God does since they are (1) created and (2) embodied. Humans can have more or less existence. For example, somebody who has lived a long time and has done good and virtuous things and has gained a lot of knowledge we might describe as having “a full life.” Such a person has reached a greater state of perfection. I do not a moral state of perfection but an ontological state of perfection. They have reached a greater or fuller state of being. They have lived the way humans are supposed to live.

God, we have already established, is pure Being, because God is pure form. Since God is pure and simple Being, there is only one way for God to exist. In other words, God does not have more or less existence like human beings do. So all the “perfections” that we ascribe to humans to indicate the extent to which they are fulfilling how they are supposed “to be,” perfections like goodness and knowledge, are already in God because God is simple Being. God is not better or worse, or does not exist in a fuller or lesser way. God simply IS. And this means that any perfection that we would derive from existence is simply in God.

Aquinas uses this idea of God’s perfection to shed light on the scriptural passages that refer to different “perfections” of God like God’s knowledge. He looks at Romans 11:33, for example, “O the depth of the riches of the wisdom and knowledge of God” and Job 12:13 “With God is wisdom and strength, counsel and understanding” and Hebrews 4:13 “All things are naked and open to his eyes.” Aquinas’ explanation is metaphysical. Since God is simple being, God’s knowledge is not a perfection that exists apart from God’s being. As Levering writes, “God is his knowledge, and his knowing is infinite. Knowing is a perfection of His infinite Act” (86). Simple existence that God reveals of his identity in Scripture, from which all created things take their existence demands that God is also perfect and knowing.

But surely Levenson would argue that this is exactly the God that is not revealed in Scripture, but rather the philosophers’ god superimposed on the scriptural account. Levering would point to Scripture accounts of God not knowing, such as in Genesis 3 when he questions the woman. If God knew everything, why the questions?

Aquinas’ response to Levering is that Scripture clearly indicates that God is all-knowing. However, in describing the ways that human beings can relate to God, the authors of scripture sometimes portray God’s knowledge as incomplete, not because God’s knowledge is incomplete, but because human language is insufficient to describe the complex ways that human beings relate to God. Human beings know, to return to our last post, in an analogous fashion to the way God knows.

Human knowledge in Aquinas’ theory is obtained in two operations. The first operation, the sensitive operation, is when the sense perceptions like vision and hearing and touching perceive a particular object. Sense knowledge then is knowledge of particular things like a particular dog. The second operation is the intellective operation. Intellective knowledge is knowledge of universal things, that is, what makes this particular furry and barking thing in front of me a “dog.” So human knowledge proceeds from particular things to the ideas behind those things; that is, human knowledge processes from sensory knowledge to intellective knowledge of the ideas behind the sensory objects.

Another way of explaining this is with the distinction between form and matter (see this and this earlier post for more explanation). In Aquinas’ view, all things are composed of form, or the essence of what they are (the dogginess in the dog) and matter, the particular individuating “stuff” which makes one dog a particular dog and distinguishes it from other dogs. The sensory operation of knowledge perceives the various aspects of the dog like fur, four legs, paws, canine teeth. The intellective knowledge abstracts from the particular matter and judges the “thing” to be a dog. It is the intellect that allows a person to say that both a Chihuahua and a Doberman, despite their differences. That is, it is the intellective operation that allows a human to abstract the form “dog” from the particular substance.

Truth consists in the equality of the intellect with its object. True knowledge of a dog is when the intellect rightly abstracts the form “dog” from the particular substance, rather than abstracting the form “cat” or “bear” despite certain similarities in the particular matter.

God’s knowledge is different. God does not have a body, so obviously, God does not know things through a sensitive power. Nor is God’s knowledge a distinct power in God. As we established above, as simple Being, God is God’s own knowledge. So how does God know? God knows, according to Aquinas, because God is the cause of all things. God knows things because God makes them. God’s knowledge, therefore, (and this is the important part) is not affected by and dependent on what is known, but God’s knowledge is what causes anything to be known.

For humans, something must exist (even as an abstraction like a dinosaur) for it to be known. For God, it is the opposite. God must know anything for it to exist. God’s knowledge is logically and metaphysically prior to existence. God’s causative knowledge raises a huge theological problem, namely the problem of evil, because if God’s knowledge causes all things, then how can we say that God does not thereby cause evil. We will address this problem in another blog post. But for now, it is sufficient to address Jon Levenson’s claim that God has incomplete knowledge with the metaphysical claim that our knowledge is analogical to God’s. So we have to use analogical language to talk about God’s knowledge. God does not know through sensory perception like we do, nor does God know in stages of perceiving, abstracting, and judging like we do. God’s knowledge of a dog, in its essence, is metaphysically necessary (though not sufficient) for the dog to even exist, much less be known according to human knowledge.

YHWH: God’s Being as Simple Being

Continuing on with our examination of Matthew Levering’s Scripture and Metaphysics, in this post I will give a concrete, hopefully simple, example of how metaphysical speculation can enhance our understanding of Scripture.

In examining Scripture, there are numerous passages that refer to God’s body. In Exodus 33, God speaks to Moses face to face, and allows Moses to gaze upon his back. Psalm 33 anthropomorphically depicts God sitting on his throne in heaven and looking down on the earth to judge the righteous and the wicked. Scripture frequently refers to God’s “right hand” (Psalm 48:10, Acts 7:56). However, Christianity holds that God is not a body, but that God is a spirit. In light of the scriptural passages that say otherwise, how can Christianity hold such a belief?

Aquinas, as Matthew Levering points out, provides one such way of interpreting these seeming conflicting passages, by using metaphysical reflection to illumine the relevant passages of Scripture. He begins with John 4:24: “God is a spirit” as providing the basis of his metaphysical reflection (Ia, Q. 3, art. 1). He then goes on to say, in light of the biblical quotations which describe God in bodily terms, that the Bible “puts before us spiritual and divine things under the comparison of corporeal things” (Ia, Q. 3, art. 1, ad. 1). Aquinas’ point is that human language must rely on sensible images to describe God, though God is immaterial.

But how do we know this is the case? In light of the numerous Scripture passages that say otherwise, would it not make more sense to conclude that God has a body (and a spirit, to take into proper account John 4:24)? Aquinas uses metaphysical arguments to the contrary. First, a body is composed of matter, and it would be impossible for matter to be attributed to God. This is because matter exists in a state of potentiality.

Aquinas takes his understanding of potentiality from Aristotle. Aristotle’s definition of potentiality in the Metaphysics, is the “power that a thing has to produce change” or “the source of change in something else or in itself qua other.” (1046a12). The exercise of potentiality is movement or process (kinesis) or actuality (energeia). So a thing has potentiality in so far as it is capable of changing, and especially in so far as it is capable of taking on a better or more complete state of being.

We can think of potentiality as “potential energy” in physics. A stone sitting at the top of the hill has potential energy, which will be translated to movement (kinesis or kinetic energy) as the stone rolls down the hill and comes to a rest. But metaphysically, potentiality has a wider meaning that refers to states of being. An infant, for example, has potentiality to grow into an adult, thus taking on a more perfect or more complete state of being, because as an adult, the infant will be able to do more things properly ascribed to humans (walking, talking, reasoning, making art) that an infant cannot do.

According to Aristotle, everything in the universe can be described as a combination of form and matter. Matter is the raw material of things, whereas form is the structure of a thing or the “essence of what a thing is.” A woman and a gazelle are both composed of matter, and some of the same types of matter (like carbon, oxygen, nitrogen) but the two substances are distinguished by their form—the woman has the form of a human and the gazelle the form of the gazelle. All matter is in a state of potentiality because it could take on any number of forms. So matter is the “waiting to happen” part of existence; form is the “happening” part of existence. An infant’s matter will change over time, but the form, the essence of what that infant is, will remain constant, which is why the three year-old, 20 year-old, and 90 year-old “former infant” can still be said to be the same person.

Things that have bodies, therefore, are in a state of potentiality. They are changing, they are always in the process of becoming. So if God had a body, God would be in a state of change. But Aquinas, based on both Scripture and metaphysics, does not accept that God changes. He cites James 1:17 that in God “there is no change nor shadow of alteration” and Malachi 3:6 “For I the Lord do not change” and Numbers 23:19: “God is not as a man, that He should lie, nor as the son of man that He should be changed” (see Ia, Q. 14, art. 10 and Q. 19, art. 7) Using these passages of Scripture, Aquinas can then return to his metaphysical speculation—things that have bodies composed of matter are in a state of potentiality, and therefore they change. But God does not change. Thus, God must not have a body composed of matter.

Metaphysically, this informs Aquinas of something important. He accepts the Aristotelian dictum that all things are composed of matter and form or potentiality and actuality. But if God does not have matter, then God must be only form, and if God is only form, then God must be only actuality without any potentiality. Another way of saying this is that God is “pure Act” or the perfect fullness of “to be.” Moreover, things that are composed of matter and form are composites, but God is not composed of matter and form and therefore cannot be a composite. Thus, Aquinas concludes, that God is simple.

These are the two metaphysical assumptions which Aquinas bases all subsequent metaphysical reflection when discussing God’s existence: (1) God is pure Being or pure Act and (2) God is simple. Although he uses metaphysical language to make these claims, Aquinas is not doing pure metaphysical speculation. In other words, he is not just recapitulating the “static Aristotelian conception of the deity” as a “mere philosophical problem” (Levering 86) but is rather using Aristotelian metaphysics to illuminate an understanding of the God of Israel and this God’s relation to human history.

For Aquinas, the language of God as “pure Being” is not separable theologically from the revelation of “YHWH”: “The two names complement each other, revealing God’s historical presence as infinite, sheer, eternal Presence. They express the same God, understood metaphysically and historically” (Levering 61).

So why use the metaphysical language at all? Because, as we saw at the beginning of this post, Scripture uses language to refer to God that describes God in human terms, and as such, the language of Scripture can possibly dispose readers to idolatry, to create God according to a human image. According to Aquinas, as Levering points out in his book, the metaphysical language God ascribes to Godself in Exodus 3:14 is intended to wean God’s people from idolatry by revealing God as pure being and nothing more, without any particular mode of being (i.e. as simple) and consequently, and here is the important part, as sheer presence.

Because God does not have any particular mode of being, God is eternally present. As YHWH, the God of Abraham, Isaac, and Jacob, God is intimately active without being limited by temporality. There should be no doubt that Aquinas is not trying to create a philosopher’s God who is detached from creation, but is rather trying to use metaphysical language to illuminate the God who is intimately close to creation, who is personal, and eternally present. God as Aquinas describes him in the language of Greek metaphysics as Pure, Simple Being is also the living and creating God of Israel. On this point, Thomas Weinandy finds a unity of metaphysical and historical naming of God in Christian thought:

Within Greek though these attributes [e.g. imperishability, perfection, goodness, power] constitute God as one who is removed from, even if related to, all else that is. They constitute him as transcendent in the sense of not only making him other than the cosmic order, but also as often being incapable of actively relating to the cosmic order. Within the Judeo/Christian tradition these attributes do constitute God as wholly other than all else, but they equally constitute him as Creator and so immediately related to all else that is” (Weinandy, Does God Suffer?, 72)

So here we have one example of how Aquinas uses both Scripture and metaphysical reasoning to illuminate God as revealed in Scripture, namely, as a God who is simple (not composite form and matter but rather pure form without a body) and a God who is Pure Being.

Questions:
1. Aquinas uses metaphysics to make sense of all those scriptural passages saying that God has a body. How do you make sense of those passages?
2. It is very important for Aquinas’ understanding of God that God does not have a body. In your mind, what difference does it make if God does or does not have a body?
3. Does describing God as “Pure Being” obscure or illuminate God as God is revealed in Scripture, especially in light of the fact that God gives the name YHWH “I am who I am” to Moses as the name by which God should be called.

More on Metaphysics

As I mentioned in my last post, I am doing a series of articles on Matthew Levering’s new book entitled Scripture and Metaphysics: Aquinas and the Renewal of Trinitarian Theology, largely in hopes of starting an ecumenical conversation between traditions like the Church of Christ that tend to be sola Scriptura, and traditions like Roman Catholicism that tends to be heavily philosophical. The point of this blog is to probe deeper into the subject of metaphysics, in order to understand why Levering’s project is so important.

In the last post, I said that Protestant theology tends to reject metaphysics in favor of using Scripture to understand God. This claim, however, requires some clarification. There are several different ways of “rejecting metaphysics.” As I mentioned before, metaphysics is simply the study of that which is not physical like God, angels, demons, and the soul. One way which a person could reject metaphysics is by rejecting that any such metaphysical or immaterial realm exists. This is a move frequently made in the modern sciences, and is sometimes called materialism, meaning that only a material realm of reality which is subject to empirical inquiry exists.

One example of a materialist rejection of metaphysics is found in this recent op-ed from the New York Times evaluating the selection of Francis Collins as the director of the National Institute of Health. Collins is a geneticist and former head of the Human Genome Project, and he is also a practicing Catholic and believer in God. Collins actually wrote a book called The Language of God which tries to show how faith and new developments in genetics are not at odds, but are rather mutually reinforcing (a good Thomist position). The author of the op-ed, Sam Harris, is not so much uncomfortable with Collin’s belief in a God but rather with his position that some things “including an immortal soul, free will, the moral law, spiritual hunger, genuine altruism, etc.” are beyond scientific scrutiny. Harris writes,

As someone who believes that our understanding of human nature can be derived from neuroscience, psychology, cognitive science and behavioral economics, among others, I am troubled by Dr. Collins’s line of thinking. I also believe it would seriously undercut fields like neuroscience and our growing understanding of the human mind. If we must look to religion to explain our moral sense, what should we make of the deficits of moral reasoning associated with conditions like frontal lobe syndrome and psychopathy? Are these disorders best addressed by theology?

Collins holds the position that he does because he believes in a metaphysical realm that cannot be the subject of scientific empirical inquiry which by definition can only study material phenomena. Harris, on the other hand, rejects such a metaphysical realm. If there is a reason, according to Harris, that we think that free will, morality, and suffering are mysteries, it is simply because we have not developed sufficiently sophisticated scientific methods to study these phenomena (For a good argument that probes materialist rejection of metaphysics on a deeper intellectual level, check out this from First Things).

Christians, however, who reject metaphysics, do not do so in the same way as Harris. Christians are not materialists, meaning that they do accept a metaphysical realm. Christians who reject metaphysics do so on different grounds, namely, by rejecting the validity of metaphysical speculation or philosophical arguments to talk about God. Christians who reject metaphysics tend to claim that everything we need to know about God has already been revealed to us in Scripture, and so rather than using philosophy to talk about God, we need only to open the Bible.

There are two big reasons why that position is a problem. First, say you have an atheist or agnostic scientist or believer in science like Sam Harris and you want to talk to him about Christianity. Opening up the Bible and reading about all that God has done is going to do little to persuade someone like Harris to accept the Christian claims of faith. But say instead you close the Bible and use a metaphysical argument to engage Sam, perhaps an argument from Aquinas. You might say something like, “Sam, our senses tell us that everything is in motion, and that things are set into motion when they are acted on by something else in motion. But things were not always in motion. For example, the theory of the Big Bang tells us that before time, there was no molecular motion at all, but something must have initially set things into motion. This first mover, we can reasonably say, is God.” (For the record, this is Aquinas’ first way of five for demonstrating reasonably God’s existence).

Now Harris may or may not be convinced by such an argument, but the point is, that such an argument, which is a metaphysical argument, has the benefit of being able to show how the God which Christians take on faith is not beyond reason. Certain things can be known about this God through ordinary human reasoning. Now, faith in the living God of Israel, fully revealed in Jesus Christ, cannot be attained through mere rational speculation, but is rather an effect of God’s grace. But Aquinas believed, and I think rightly, that we can make ourselves more or less amenable to faith. Sam Harris is not going to be made amenable to faith by reading the Bible, but he might be by rational, philosophical, and metaphysical arguments. Get him convinced enough that faith and reason are not in conflict, and he may get to the point where he can actually open the Bible and read it with a certain degree of docility. So metaphysics can be a powerful tool for evangelization.

The second reason that rejecting metaphysical arguments in favor of a sola Scriptura position to understand God is a problem is that God as revealed in Scripture does not always seem to make a lot of sense. For example, a Christian may site Psalm 118, “O give thanks to the LORD, for he is good! for His mercy endures forever” and make a claim along with the Psalmist that God is good. But then somebody could open the Bible and read 2 Samuel 6 where Uzzah, a seemingly good guy and servant of God, reaches out to touch the ark of the covenant to keep it from falling, and God gets angry and strikes him dead. A person reading this passage could claim that such a God is not good. Or a Christian could say that God loves peace and mercy and cite the numerous Biblical passages which support this, like when Jesus says “Blessed are the peacemakers” or in the Old Testament:

“If your enemy is hungry, give him food to eat; and if he is thirsty, give him water to drink; for you will heap burning coals on his head, and the Lord will reward you.” (Prov. 25:21,22)

“Seek peace and pursue it” (Ps. 34:14)

But then someone else could open the Bible and look at the following passages and draw a very different conclusion:

Observe what I command you this day. Behold, I am driving out from before you the Amorite and the Canaanite and the Hittite and the Perizzite and the Hivite and the Jebusite. Take heed to yourself, lest you make a covenant with the inhabitants of the land where you are going, lest it be a snare in your midst. But you shall destroy their altars, break their sacred pillars, and cut down their wooden images. For you shall worship no other god, for the Lord, whose name is Jealous, is a jealous God (Exodus 34: 11-14)

<blockquoteYou will chase your enemies, and they shall fall by the sword before you. Five of you shall chase a hundred, and a hundred of you shall put ten thousand to flight; your enemies shall fall by the sword before you. For I will look on you favorably and make you fruitful, multiply you and confirm My covenant with you. You shall eat the old harvest, and clear out the old because of the new (Leviticus 26: 7-9)

Reading these passages, someone could make a very valid claim (as lots of people do, and they frequently abandon their faith as a result) that God is actually not peaceful and merciful, but is rather capricious and wrathful, going so far as to command genocide, one of the greatest of atrocities.

Levering says that it is all too easy to read these passages and others from the Bible and create an idol out of God. Our idol may be a wrathful God who sends down punishments on the wicked and hates his enemies. Or our idol may be a revolutionary God involved in radical societal reform and social justice. Or our idol may be a God who loves and accepts all his creatures, no matter what they do. Or our God may be a strict authoritarian who has set down rules in Holy Writ and fully expects his creatures to follow them.

All of these understandings of God are present in Scripture and thus all of them have at least some element of truth. But Levering wants to argue that taking any one of these understandings of God on its own, despite its scriptural warrant, is still making an idol out of God.

Levering wants to make the claim in his book that a basic metaphysical assumption about God is that God is reasonable, and thus, we can use our reason to understand and explain these seeming conflicting passages about God. That is, if we put metaphysical speculation about God into dialogue with scriptural exegesis about God, we can come up with an understanding of God that is richer, truer, and less prone to idolatry. We will go into the details of how Levering thinks this should proceed in later posts, but he basically wants to argue that Thomas Aquinas’ metaphysical assumptions allowed him to resolve apparent conflicts regarding God as God is revealed in Scripture. Metaphysical speculation allowed Aquinas to make sense of Scriptural accounts of the seeming capriciousness of God and scriptural accounts of God as unchanging. Aquinas’ metaphysical speculation allowed him to make sense of the Christian claim that God is good, despite Scriptural evidence to the contrary. Aquinas’ metaphysical speculation allowed him to make sense of the fact that God is one, despite the fact that Christianity hold that Jesus and the Holy Spirit are also God. And Levering thinks that these are exactly the tools that Christians need to today in order to understand God and enter into greater union with that God.

Scripture and Metaphysics: Aquinas and the Renewal of Trinitarian Theology

Metaphysics is that science which studies all that is beyond the natural world, yet still relates to the natural world. Metaphysics studies the nature of being (ontology) and causation and transcendentals (the Beautiful, the Good, the True). Metaphysics (meta ta phusika) itself simply means “beyond the physics” and was the word assigned to the sequel of Aristotle’s book the Physics which examined the natural world. Everything that our senses can perceive is subject to contingency and change and it is these things that are the object of the study of physics. Metaphysics studies those things which are beyond apprehension of our senses. We can perceive a rock or a tree or a piece of cake with our senses, and so these can be the subject of physical inquiry. But we cannot perceive God or the immortal soul or spiritual beings like angels with our senses; these, then, are the subject of metaphysical inquiry.

Aristotle himself did not use this word but called the subject of his book the “First Science,” “Wisdom,” or “Theology.” The subject of his inquiry was specifically the first cause of things or non-material things which do not change. This is sometimes described as “being qua being,” or “being as it is in itself.” Because this was the most fundamental subject, Aquinas thought the study of metaphysics as “wisdom” (sophia), the highest type of knowledge.

Metaphysics has always had a reputation of being about matters which are notoriously difficult. Andronicus of Rhodes probably assigned the title ‘metaphysics’ to Aristotle’s text indicating that the subject matter of the Physics must be fully grasped before one could understand the subject of the sequel. Metaphysicians use phrases like “essence precedes existence” or “substances, while not universals, are subjects of predication that cannot themselves be predicated of things.” Such language is especially prohibitive according to our modern sensibilities which seek to explain all phenomena in positivistic or empirical language. Kant rejected metaphysics because he claimed that the immaterial world was beyond intellectual inquiry. Hume claimed that all we could know was what we could experience, thus precluding metaphysics as a viable mode of inquiry since it was specifically about things which could not be experienced. Modern materialists reject metaphysics because they claim there is no immaterial world–all that exists is what we can apprehend with our senses.

In Christian theology, metaphysical language has been used to talk about and explain various things about God. In the creed, for example, when you say, “begotten not made, one in being with the Father,” you are expressing a metaphysical conclusion which was once a hot debate in the early church. Metaphysics has been especially employed throughout history to discuss the nature of the Incarnation (word becoming flesh) and the Trinity (one being or ousia of three persons or hypostases). Aquinas relied heavily on metaphysical language to explain these mysteries. Aquinas used metaphysical language to talk about God’s simplicity (that he lacks composition), his perfection, his eternity, his immutability, and his power. But he also employs heavily metaphysical language to explain the doctrine of the Trinity. That is, given that God is one and simple, how can we also say that God is three persons?

Much of Protestant theology has assumed an irreconcilable division between Scripture and metaphysics. For many Protestants, the best way to talk about God is not in the metaphysical language of being, but rather in the language that God gives us in Scripture. That is, if we want to understand God, we turn to Scripture which tells us who YHWH is, who Jesus Christ is, and who the Holy Spirit is.

There is good reason for this turn to Scripture, rather than philosophy, in order to understand God. Luther, for example, quite famously said that metaphysics was prohibitive for understanding God, and was a way of getting around the fact that the living God has revealed himself historically in Scripture. Moreover, it is hard to deny that it is much easier to be inspired and captivated by the scriptural tales of the various acts of the God of Israel, and the stories of Jesus, and the Pauline arguments about Jesus’ significance than it is to be inspired and captivated by a discussion like the following from Aquinas’ treatment of the Trinity:

the divine simplicity requires that in God essence is the same as “suppositum,” which in intellectual substances is nothing else than person. But a difficulty seems to arise from the fact that while the divine persons are multiplied, the essence nevertheless retains its unity. And because, as Boethius says (De Trin. i), “relation multiplies the Trinity of persons,” some have thought that in God essence and person differ, forasmuch as they held the relations to be “adjacent”; considering only in the relations the idea of “reference to another,” and not the relations as realities. But as it was shown above (Question 28, Article 2) in creatures relations are accidental, whereas in God they are the divine essence itself. Thence it follows that in God essence is not really distinct from person; and yet that the persons are really distinguished from each other. (Ia, Q. 39, art. 1).

However, the assumed antagonism between Scripture and metaphysics is in many ways a straw man. First of all, Scripture uses metaphysical language to talk about God. When God tells Moses “I AM who AM,” he is using metaphysical language. The Prologue of John is heavily metaphysical:

In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things came into being through him, and without him not one thing came into being. What has come into being in him was life, and the life was the light of all people.

Second of all, many of those who use metaphysics, like Aquinas, do not do so in order to replace Scripture, but rather to shed light on the mysteries narrated by Scripture.

Overcoming the antagonism between Scripture and metaphysics is the subject of Matthew Levering’s excellent new book, Scripture and Metaphysics: Aquinas and the Renewal of Trinitarian Theology, which I will be discussing in subsequent blog posts. Levering argues that metaphysical speculation about God, rather than rendering God distant and meaningless, is necessary to ensure that our worship is oriented towards Israel’s God, rather than culturally relevant idols. Aquinas, he argues, is an invaluable guide for learning how metaphysics enhances our understanding of Scripture and deepens our knowledge and union with God. He writes in the introduction,

We learn from Aquinas how the language of ‘being’ [metaphysical language] preserves Israel’s radical insistence upon the intimate presence in the world of her transcendent god, a presence that is ultimately Messianic, given the evil of the world. Aquinas exposes how the doctrine of divine Personhood attains real knowledge of, without over-narrating, the inner life of God as revealed in Scripture. He finds in the proper names of the Trinity—father, Son, Word, Image, Holy Spirit, Love, Gift—the biblical distinctions of the divine communion-in-unity into which our lives have been salvifically drawn. Against supersessionism, including the unconscious supersessionism that is Trinitarian ontology, he teaches Christians that we must always speak of our triune God under two aspects (4).

Metaphysics, for Aquinas and for Levering who wants to defend Aquinas, belongs to the personal encounter in which human beings use human words and human concepts to truly express divine revelation. Aquinas uses metaphysics to illumine the meaning of Scriptural revelation, to talk in a meaningful way about the God who has made himself known, and ultimately, to help Christians contemplate and enter into greater union with this living God. A Jean Pierre Torrell writes:

When Thomas says that theology is principally speculative, he means that it is in the first instance contemplative; the two words are practically synonymous in Thomas. This is why—we shall not be slow to see this operative in Thomas’ life—research, study, reflection on God can find their source and their completion only in prayer. The Eastern Christians like to say of theology that it is doxology; Thomas would add some further clarifications to that, but he would not reject the intention: the joy of the Friend who is contemplated is completed in song (Saint Thomas Aquinas, Vol. 1: The Person and His Work, 157).

On a final note, I hope this post and the subsequent posts I write on this book and the topic of scripture and metaphysics will foster ecumenical dialogue. As a Roman Catholic married to a member of the Church of Christ, and as a regular mass attendant and active worshipper in a local church of Christ, I am very interested in finding points of similarity and unity between a tradition that is heavily speculative and metaphysical, and a tradition that is historically rationalistic, positivistic, and solely reliant on Scripture to know God and how to worship him. I think that Aquinas is an invaluable resource for this dialogue, and for future ecumenical dialogue between Roman Catholics and other Christian traditions, and I hope that these posts can help to foster an ongoing conversation between different Christians who seek to climb the steep mountain of the knowledge of God.

How Should Christians Make Sense of the Theory of Evolution?

In John Paul II’s message to the Pontifical Academy of Science on Evolution in 1996, he finely summed up the Roman Catholic Church’s stance on evolution, reaffirming the statement made by his predecessor Pius XII in 1950 that “there was no opposition between evolution and the doctrine of the faith about man and his vocation.” The conflict among theologians over evolution according to the pope was not whether Darwinian theories were compatible with Christianity, but rather “the true role of philosophy and, beyond it, of theology.” Some, like Cardinal Christoph Schoenborn in this NYTimes Op-ed, claim that John Paul II’s support for evolutionary theories are overblown. Pope Benedict XVI said in his 2005 inaugural mass that “We are not some causal and meaningless product of evolution. Each of us is the result of a thought of God. Each of us is willed, each of us is loved, each of us is necessary.” But this should not be taken as a Catholic hostility to the theory of evolution, per se. For both John Paul II and Benedict XVI, science and religion are ultimately compatible, each with different questions, tools, and spheres of influence, but at certain points, mutually enlightening.

Evolution is a materialist theory, meaning that it is a theory concerned with matter. It explains the reorganization of matter over time. As an empirical theory, it is based on observations and measurements. The job of the natural sciences is to explain such natural phenomenon like the differences between the species or the biological development of organisms over time.

But there are other disciplines that study phenomena that are not natural, not concerned with matter, and not empirically observable. For example, the soul, according to Christian theology is immaterial. Thus, it cannot be explained by a materialistic theory like evolution. Rather, the question of the soul is a metaphysical question. Metaphysics simply means “beyond or above physics.” Whereas physics and the other natural sciences are concerned with nature, that is, observable and measurable phenomena, metaphysics is concerned with that which cannot be observed, with those deep and abiding questions of why. Why are we here? What is our purpose? What is the soul?

It is concerning the question of human evolution, particularly when it comes to humans having an immortal soul, where evolutionary theories and theology really seem to conflict. It seems directly contrary to the Biblical account of creation to say that human are the process of natural selection. Moreover, it seems repulsive to the idea of human dignity rooted in the belief that human beings are created in the image of God to say that human beings and monkeys descended from a common ape-like ancestor. How can human beings bear the divine image if one accepts that they are descended from an animal?

Thomas Aquinas offers us one such solution. Thomas Aquinas adopted Aristotelian biology to explain the biology of the human being. Aristotle thought that human beings were animals, and Aquinas affirmed him on that. According to both, the organizing structure (or form) of the human being was the soul, which was both immaterial and inseparable from the body (unlike Plato who thought the soul was imprisoned in the body). In the Aristotelian view, the human soul had three levels. The most primitive level was the vegetative level that allowed the human being to do plant-like things like grow through cellular division or use energy. The next level of the soul was the animalic level, which allowed the human being to do animal-like things like hunt down food, attack in self-defense, and mate with other human animals. But where humans were distinct from their fellow animal kingdom members was that they had a third level of their soul—the rational part–which allowed them to do things like think, ponder, form communities, create moral codes, resist animal instincts, and wonder about God. Most importantly, it is the rational part of the soul that allows the person to have free will, that is, the ability to act voluntarily and intentionally. The idea of the soul as having multiple levels allowed Aristotle and Aquinas to conceive of the human person as both an animal and more than an animal.

According to Aquinas, it is in the rational part of the soul that we find the image of God. This is an important point to emphasize: for Aquinas, being in the image of God means being able to act (1) voluntarily and (2) with intention or purpose.

So this gets to why the Roman Catholic Church, which is heavily influenced by the theology and philosophy of Aquinas, can accept evolution. It is because the church sees the realm of philosophy and theology to be concerned primarily with the rational dimension of the soul and with the human being as a free and intentional creature, capable of conceiving a realm of reality that is not material, a realm of reality that is concerned with immaterial, or metaphysical phenomena like the true, the good, and the beautiful.

It is not the job of philosophy and theology to explain functioning of the other parts of the soul that control things like cell division and appetite. This is the job of the natural sciences like biology. Theology, since it is based on revelation, cannot explain the exact observable mechanisms of the way the world works or the way God creates. Saying that God created the earth is one thing; explaining how is quite another. Science, on the other hand, cannot explain the deep and inescapable existential questions that arise in human existence. Why are we here? Where are we heading? How do we lead a good life?

There are reductionist tendencies on both sides of the debate. There are some religious folk who say that everything we need to know is in the Bible. This sort of Biblicism (sometimes called fundamentalism) is ultimately self-defeating. The majority of even the most stringent Biblicists or fundamentalists will go to a doctor when they are sick. The Bible talks about healing, so why not turn to the Bible for answers to an illness? Because the Bible does not give us those answers. The Bible does not tell us how to set a broken bone or how to cure strep throat. To think that the Bible provides all the answers is an example of reductionism.

The reductionist tendencies on the scientific side of the debate try and use science to provide all the answers. We said before that religion can provide answers to the deep-seated metaphysical questions that emerge in each of our lives, but scientific reductionists will say that science provides answers to these questions. To the question, “why are we here?” scientific reductionists will say that we are not here for any reason, but are rather the products of chance. To the question, “what happens when we die?” scientific reductionists will say that nothing happens when we die besides the fact that our biological mechanisms cease to function. To the question, “how do we live a good life,” scientific reductionists will say something like “there is no such thing as a good life, only as much subjective pleasure as possible.” But like the religious reductionist position, this scientific reductionism is also ultimately self-defeating. There is no scientific (i.e. empirical) evidence to prove that there is no God or that chance, not God, is the force behind the evolutionary processes. You cannot use the tools of science to examine metaphysical questions like the meaning of life, the nature of God, or the question of final causality.

This is why Darwin’s theories have never been officially condemned by Vatican. Darwin sought to explain a physical question, whereas the church seeks to explain metaphysical questions. Now, metaphysical explanations are partially dependent on physical phenomena, but metaphysics goes beyond what physical theories like evolution can tell us. Theologically, it would be devastating for the acceptance of evolutionary theories if they embraced a view of human beings as wholly material, and indeed, some evolutionists believe this. But Darwin did not, and strictly speaking, evolutionary theories do not contribute to such a view of mankind.

Neighbor Love, Natural Law, and Universal Moral Norms

Last Thursday, Barack Obama spoke at the Annual Prayer Breakfast about his faith and what he sees as the role of religion in public life. Judging from the fact that President Obama referred to unbelievers as “humanists,” it is pretty clear what Obama thinks religion is there to do: help us love one another.

“Whatever our differences, there is one law that binds all great religions together. Jesus told us to ‘love thy neighbor as thyself.’ The Torah commands, ‘That which is hateful to you, do not do to your fellow.’

” In Islam, there is a hadith that reads ‘None of you truly believes until he wishes for his brother what he wishes for himself.’ And the same is true for Buddhists and Hindus; for followers of Confucius and for humanists.

“It is, of course, the Golden Rule -– the call to love one another; to understand one another; to treat with dignity and respect those with whom we share a brief moment on this Earth.”

The interesting thing about this claim our president is making is that it rests on anthropological and metaphysical principles that we all do not actually agree on. Conservative Christians, for example, lost no time in pointing out the hypocrisy of President Obama’s insistence that there is no God who condones taking the life of an innocent human being when he has one of the most consistent pro-choice records of any politician around today. This is because Barack Obama does not think that the fetus is a full human being with full moral rights; Conservative Christians do.

Turns out, in the history of humanity, we have never been all that clear about what it means to be human or what counts as a full human being. Metaphysically, the question is “what is the essence of humanity?” Some people think we can resolve this question through practical reasoning and consensus. Jacques Maritain, for example, thought that natural law reasoning could provide the philosophical foundations for an anthropology that would support the drafting of the 1948 UN Universal Declaration of Human Rights. Maritain thought we could get all nations together and agree on such rights even if we did not agree on their metaphysical presuppositions. But as post-1948 history has illustrated, we might like the rights when they apply to ourselves, but it still isn’t all that clear who counts as human and gets to benefit from them. Our progressive-minded president draws a line in the womb somewhere. Peter Singer draws the line at infants. Aristotle drew the line at barbarians, women, and natural slaves.

A lot of people, many of them Catholic but not all, think that natural law can provide a fixed understanding of human nature. The idea is basically that human beings can rationally derive what it means to be a human, and what is normative for human nature, based on rational discernment about what is “natural.” Some have described this as an unwritten law on the human heart, and it is normally not thought of a religious way of thinking about humanity and morality. The Founding Fathers in the United States were deists, and were very influenced by natural law reasoning from the Enlightenment that led them to the American Proposition that “all men are created equal.” Because of its characteristic “unreligious” nature, natural law reasoning has been dismissed by many Protestants like Karl Barth who claim that God’s will, not human reason, is up to the task of figuring out what human beings are and what they are supposed to do.

Natural law, as defined by Aquinas (though Aquinas’ definition in no way exhausts all the different ways natural law has been conceived from the time of the pre-Socratics to the present) is the rational creature’s participation in the Eternal Law (I-II, Q. 91, art. 2). The natural law is a capacity to distinguish between good and evil that rational creatures are endowed with. This capacity is expressed through moral precepts like the Golden Rule. The natural law can yield more specific precepts and includes a fundamental capacity for moral judgment, but there is considerably less certainty on the level of particular norms. Basically, the Golden Rule might be absolute and universal, but how to apply it is not. Rather than thinking of the natural law as a series of universal norms, it is better to think of it a rational principle of discernment–a built-in mechanism human beings have to discern between good and evil.

What the natural law does not give us, despite what some people think, is a fixed understanding of human nature. Natural law does not allow us to grasp absolute, fundamental, and universal aspects of human nature. Rational discernment gives us an idea of what is fundamental to human nature, but our ability both to know these elements and to express them is limited, not only by our inability as finite creatures to grasp the absolute and the universal, but also due to sin which clouds our intellect and veils the truth. Moreover, human nature is not something that exists in a fixed way prior to becoming embedded in a culture, but is rather a political or social thing. God may know the essence of human nature, and what should be normative for human beings to do in any given situation, but human beings do not have access to such knowledge. As Reinhold Niebuhr said, the one absolute is that human beings do not know the absolute.

What we get from natural law reasoning are a lot of different norms and a lot of different ideas about human nature. Aristotle, Aquinas, Peter Singer, and Barack Obama are all using the natural law to make judgments about what is good and what is evil, and I am betting that none of my readers agree with all of them. Although modern natural law theorists have attempted to provide a universal moral code based purely on practical reasoning, I think this is an impossibility. Natural law reasoning, rather, is always embedded in a particular belief system and a particular metaphysical conception of the good. You cannot separate the work of practical reasoning from the political, social, and religious environs in which such reasoning occurs, nor can you present a definition of human that is detached from such an environs. At least, not an absolute or universal definition.

So what are we to do in this global environment where we are desperate, as President Obama illustrates, to find commonalities, or the universal among all the particularities? Does natural law provide us with any way of generating universal norms or a universal definition of what it means to be human? Jean Porter has argued convincingly that people like Thomas Aquinas thought of natural law as a Scriptural concept, that his understanding of human nature was guided by scriptural and theological principles of interpretation. Consequently, Aquinas’ idea of human nature was not grounded in the conclusions of pure practical reasoning, but rather in the image of God in the person of Jesus Christ. For thinkers like Aquinas, natural law reasoning occurred at the locus where reason and revelation occurred, and this allowed him to construct an elaborate, virtue-based ethic delineating not only what was possible but also what was desirable for human nature under the aid of grace. What is normative for the human being under such specifically Christian natural law reasoning is not just the Decalogue and the two-fold command to love God and love your neighbor as yourself, but also the call to perfection in the Sermon on the Mount, the fruits of the Spirit in Galatians, and that ever-tricky love of enemy.

The consequence of this idea of natural law is that Barack Obama cannot just say that everybody across the globe knows to “love their neighbors as their selves.” I’m sure the Hutus bought into that as they were slaughtering the Tutsis. Good thing the Tutsis weren’t neighbors. The British probably bought into as well as they were legislating apartheid in South Africa to keep the non-neighbor Africans in their place. The German National Socialists, many of them good Lutherans in their free time, undoubtedly thought love of neighbor was important, but Jews and Communists and homosexuals were fair game. And Barack Obama can cite the universality of the command in front on the National Prayer Breakfast with a clear conscience, even though he thinks that partial birth abortion is okay, and has done all he can to make sure it stays legal in this country.

For Christians, who counts as the neighbor cannot be separated from what revelation through Scripture tells us. For the hard-core biologist, the neighbor will be defined differently, probably based on some scientific standard for who counts and who does not. For the philosophical humanist, we will get another definition. Barack Obama is right to point out the universal nature of the Golden Rule, but the Golden Rule tells us practically nothing. As the Gospel of Luke, chapter 10 indicates, the juicy part of that question is “who is my neighbor.”

Revealed Knowledge of God

Today’s first reading for Mass from 1 Samuel presents the perfect opportunity to talk a little about natural knowledge of God and revelation, a topic which I have also written about here.

Samuel is sleeping in the temple of the Lord where the ark is when he hears a voice calling him. Thinking the voice is coming from Eli, the only human voice around, he runs to him saying “Here I am. You called me.” When this has happened twice to Samuel, the author tells us, “Samuel was not familiar with Yahweh because the lord had not revealed anything to him as yet.” The NRSV makes it clearer “Samuel did not yet know Yahweh” (1 Samuel 3:7). Because God had not yet revealed himself, Samuel attributes his experience–hearing this voice–to a natural cause. Only when it happens a third time does Eli realize that no natural cause could explain Samuel’s experience. “Eli understood that Yahweh was calling the youth. So he said to Samuel, ‘Go to sleep, and if you are called, reply, ‘Speak, Yahweh, for your servant is listening.’” The next time that Yahweh calls out, Samuel is able to respond correctly. He knows who is calling.

If you went to Mass this morning, you probably heard a slightly different reading of the story. Instead of “Yahweh,” you probably heard “the LORD.” When you see in your Bibles the word “LORD” in small capital letters, what you are seeing is the translation of the transliteration of the Hebrew word for “Yahweh.” I used Yahweh in my own version of 1 Samuel to emphasize that the young Samuel is not receiving just any revelation, but is learning the proper name of the God of Israel.

Thomas Aquinas’ second question of the Summa Theologica is on the existence of God, a part of the Summa often quoted and studied in intro. Philosophy classes and often misunderstood. First, Thomas asks whether the existence of God is self-evident. He answers, “No one can mentally admit the opposite of what is self-evident; as the Philosopher [Aristotle] states concerning the first principles of demonstration. But the opposite of the proposition “God is” can be mentally admitted: ‘The fool said in his heart, There is no God.’ Therefore, the existence of God is not self-evident.”

Something is only self-evident, according to Aquinas, if the essence of the subject includes the predicate like “a zebra is an animal” because the essence of zebra, what makes a zebra what it is, includes animal in it. Regarding God, Aquinas says that if we say “God is,” the statement in itself would be self-evident because God includes his own essence. There is no predication in God. But here’s the rub: “Now because we do not know the essence of God, the proposition is not self-evident to us, but needs to be demonstrated by things that are more known to us, though less known in their nature, namely, by effects.”

Thomas’ main interlocutor here is John Damascus who says that “the knowledge of God is naturally implanted in all.” Aquinas agrees that the knowledge of God is in us naturally–sort of. Here, the passage in 1 Samuel is helpful. Samuel hears Yahweh calling him, so in this way, he has knowledge of God because he hears the voice of God. But until it is revealed to him that this voice comes from Yahweh, he attributes the voice to other things, namely, Eli. Aquinas writes,

“To know that God exists in a general and confused way is implanted in us by nature, inasmuch as God is man’s beatitude. For man naturally desires happiness, and what is naturally desired by man must be naturally known to him. This however is not to know absolutely that God exists; just as to know that someone is approaching is not the same as knowing that Peter is approaching, even though it is Peter who is approaching; for there are many who imagine that man’s perfect good which is happiness, consists in riches, and others in pleasures, and others in something else.”

The knowledge human beings have of God naturally is analogous to Samuel hearing a voice, and not knowing who it comes from, or seeing a person approaching and not knowing who it is. Not very useful knowledge.

But Aquinas still wants to insist that we can know that God exists naturally. Our knowledge of his existence comes from his effects. For Aquinas, the universe is constantly in motion, and it is this motion which is mysterious and needs to be investigated. Motion means that the universe is always in a state of flux, because when one thing moves, it impacts another. And because the universe’s change is attributable to motion, the universe can be investigated according to principles of causation.

Aquinas, when he looks around the universe, tries to explain things in terms of Aristotelian causation, as he claims all humans do. But this chain of causation cannot be endless. There must be some first cause. There must be some first efficient cause, some unmoved mover or necessary “causer” on which all other contingent causes derive their existence. This, Aquinas says, is God, which he explains in the second question of the Prima Pars. This first cause is what is naturally sought out by the intellect. In other words, the intellect was made to seek out knowledge of God in this way. Aquinas writes,

The existence of God, like other truths about God, which can be known by natural reason, are not articles of faith, but are preambles to the articles; for faith presupposes natural knowledge, even as grace presupposes nature, and perfection presupposes that something can be perfected (I, Q. 2, art. 2, ad. 2).

What Aquinas is trying to do is show that the intellect can come to some natural knowledge of what God does through his effects. But this tells us nothing about the essence of God. What or Who or the Essence of God remains beyond us. The human intellect, says Aquinas is not made to know anything naturally about God.

For knowledge of God, the human depends on grace. In the first question of the Prima Pars, Aquinas says that sacred science (I.e. theology) is necessary because the human being does not naturally know God, and so a further principle, revelation, is necessary. This first question regarding the importance of revelation guides the rest of the Summa. When Aquinas says that the effects of God in the universe lead the intellect to posit God as their cause, he emphasizes that revelation is still necessary in order to know anything about this first cause. The intellect depends on God’s grace to elevate it and allow it to grasp knowledge of God. Thus, faith, the theological virtue located in the intellect, is necessary to grasp knowledge of God.

In the story in 1 Samuel, Yahweh has to be revealed to Samuel. He can’t just hear the voice and know God. He must be helped, both directly by God’s self-revelation, and indirectly by the assistance provided by those who know Yahweh, in this case, Eli (this “assistance” other people provide in disclosing knowledge of God is what Aquinas calls “justifying grace”).

Fergus Kerr says that Aquinas’ five proofs are about showing how God has already been known naturally by the philosophers. He is not re-proving God, but simply rearticulating. His basis for doing so is Scriptural, and he cites Romans 1 “for what can be known of God is plain to them, because God has shown it to them. Ever since the creation of the world, his eternal power and divinity has been understood by the things he has made.” In the Old Testament, we see a fuller understanding of God, revealed in God’s election and sustaining of Israel. But the Jews also have an imperfect knowledge of God. The fulfillment of knowledge about God is found in the person of Jesus Christ, in his birth, life, death, and resurrection. It is in Jesus that God makes himself fully known.
