Does Studying Theology Make Us Certain?

Those who are familiar with Thomas Aquinas know that he begins the Summa Theologica (his magnum opus) with the question as to how one can go about studying theology. In article two of that question, he asks whether theology is a science, and to answer, he makes a critical distinction so that he can answer that theology is, in one way at least, a science, thus making the Summa itself a work of science:

Sacred doctrine is a science. We must bear in mind that there are two kinds of sciences. There are some which proceed from a principle known by the natural light of intelligence, such as arithmetic and geometry and the like. There are some which proceed from principles known by the light of a higher science: thus the science of perspective proceeds from principles established by geometry, and music from principles established by arithmetic. So it is that sacred doctrine is a science because it proceeds from principles established by the light of a higher science, namely, the science of God and the blessed. Hence, just as the musician accepts on authority the principles taught him by the mathematician, so sacred science is established on principles revealed by God.

In other words, theology is a science, Aquinas says, if we understand it as a sort of “subalternated” science which derives its first principles from another science. Unlike other subalterated sciences like music or optics, however, theology derives its first principles from a non-demonstrable science. Godfrey of Fontaines explains why this is so:

[I]f theology were truly and properly a science after the model of a subalternated science in relation to a subalternating one, it would be necessary that the principles of theology that are had in this life be certain by the certitude of evidence at least in regard to knowledge that such is the case, and it would be necessary that there would be knowledge of why it is the case in the science the blessed have of these principles . . . So, in order that theology be science and that not only would there be faith regarding the conclusion of theology as there is regarding the principles, then regarding its principles it is necessary that they be not only believed but be known and evident. For, the type of evidence the principles have will determine the parallel type of evidence that the conclusion will have. For although a conclusion may be drawn from principles that are only believed and the consequence or the necessity of the consequence can be scientifically known, still the consequent and its necessity cannot be known scientifically from such principles (Quodlibet, IV, q. 10, 1287).

In other words, we might call music or optics a subalternated science because it derives its first principles from another science (arithmetic or geometry), or is subjected to other more proper sciences. Thus, an optician may proceed to study optics without having proper knowledge of the first principles of his science, which are derived from geometry. However, the optician may study geometry and in doing so, gain a more perfect knowledge of optics. Optics is thus subordinated or subalternated to geometry, but not in such a way that prevents a more perfect knowledge of optics through gaining a more perfect knowledge of its first principles through the study of another science.

Theology, as Godfrey points out, is not like this. Theology is based on first principles which do not come from another human science which may be studied, but rather from the science which exists in the mind of God and is consequently beyond all human understanding. “Science,” Godfrey tells us, is “a sure habit possessing both the certitude of evidence and the certitude of conviction,” which theology can never have because it is based in principles which are not certain but accepted on faith. In contrast to science, faith, Godfrey writes, is “a sure habit having only the certitude of conviction, not the certitude of evidence.” Faith may be stronger than opinion (which lacks both the certitude of evidence and conviction), but for Godfrey, because theology rests on revealed first principles which cannot be proved, it can only be faith and never science.

Is there a difference between Thomas and Godfrey? Maybe, but on the subject of theology as science, perhaps they can be reconciled. Thomas, like Godfrey, knows that the first principles of theology rest on faith. Such principles like the Trinity, Incarnation, and Eschaton cannot be proved, only believed. For Thomas, belief comes as a gift not only of intellectual propositions, but the gift of an actual relationship with God. The object of faith, while not convincing to the non-believer, is actually more certain than sensory knowledge because it is a knowledge based not only on the discursive intellect, but also the affections (as elevated by the gifts of the Holy Spirit). However, from those first principles, rational and logical conclusions can be drawn which enhance the knowledge one has of the first principles, and on this, Thomas and Godfrey are not in such disagreement. Godfrey writes:

So, when theology is posited as science, it is necessary that its principles become in some way evident and known or understood. In fact, evidence has to be of a kind that respects the excellence of its subject matter and the weakness of the human knower. Thus, to one instructed in theology, it is much more evident than to the simple layman that Christ, God and man, has risen, and how this is possible and not impossible. . . Therefore, even though such things are not as evident as are the principles of other sciences because of their lack of proportion to our intellect, still they are known by a kind of evidence that is sufficient. . . Concerning he kind of knowledge we have in theology, Augustine, in Book XIV of his De Trinitate, says: “Many of the faithful are not strong in this science, even though they are strong in the faith itself. For it is one thing to know what a man must believe in order to gain the blessed life; it is another thing to know how that which is believed may help the pious and be defended against the impious.”

So, both Aquinas and Godfrey show us that by studying theology, we are not making scientific arguments that will be convincing as science to the non-believer. However, by studying theology scientifically, that is, by logically deducing conclusions from revealed first principles, we do get a sort of science which is important, not because it makes our beliefs more convincing to the non-believer, but because we become more convinced, even in light of the opposition of non-believers. Thus, theology does enhance knowledge if conducted scientifically, even if we still might not be able to call theology a proper science.

This seems to me incredibly important today when so many believers, when faced with a materialist and empiricist scientific worldview, feel the need either to doubt or abandon their faith or to withdraw into a sectarian, anti-scientific stance. For this latter group, recovering the Medieval concept of theology as a science can help Christians engage the scientific community in a spirit of dialogue rather than polemics, and by incorporating the sciences into the study of theology, they may actually become better believers.

The Challenge of Naturalism

At an ethics colloquium this week, I heard a professor tell a story (which I hope is okay to repeat here since both the storyteller and the subject of the story are anonymous) of a former theology student who had recently written with proud news of an upcoming publication on the topic of liturgy. She went on to tell him that she was flourishing in her job as the campus minister at a Catholic school. She had recently gotten into spiritual direction, which was going okay, despite the fact that she no longer believed in God, and overall, she was very happy with her life and career.

Wait. . . she no longer believes in God? In America, this is not as rare as you might think. While Europe is becoming increasingly more secularized, and the churches are becoming more and more empty, in the US, something else is happening. Externally, we are a very religious nation with a high percentage of churchgoers (about 47% of Americans attend a weekly religious service as opposed to about 20% in Europe). Nevertheless, there are signs that we are a nation a lot like this professor’s former theology student—involved in the act of religion without the corresponding belief. As Terence Nichols puts it in his very fine book The Sacred Cosmos:

Supernatural realities such as miracles, angels, afterlife, a sacred cosmos, and so on are rarely broached, at least in mainline Protestant denominations (and less and less so in Roman Catholic churches). God has become distant from everyday life. People may still believe in God, got to church, even pray, but without deep conviction. . .(8)

For Nichols, the problem is naturalism, “the belief that nature is all that exists, and that everything can be explained by natural causes and therefore by science. There is no nonmaterial reality, such as God.” The problem, he says, is deep and

. . . originates further back—with the separation of God from nature, a split that began in the late medieval and early modern period. This resulted in the (perceived) separation of god from everyday life that is so characteristic of contemporary secular societies. . .Ancient and medieval Christians lived in a sacred cosmos and saw nature as a window or sacrament that expressed the beauty, majesty, and glory of God. . . Sacraments make God present and invite the believer into a sharing of God’s presence. But for a sacrament to work, there has to be some similarity, some unity. . . If nature is seen sacramentally, rather than as an object to be investigated and used, it also can mediate the presence of God. Seen sacramentally, nature is a sacred cosmos, for whatever mediates God’s presence is sacred (9).

Instead of a sacred cosmos infused with the supernatural, what we have now, according to Nichols, is a universe completely subject to natural laws, where even religion (to quote E.O. Wilson), is subject to the explanations of the natural sciences. This metaphysical naturalism is the greatest challenge Christianity faces in the contemporary world. As Nichols puts it,

For if nature is all that exists, there cannot be any reality that is greater than and independent of nature. Nor can there be any hope of an afterlife, nor any means to really transcend our natural condition. The consoling grace of god, which frees us from sin, addictions, selfishness, hopelessness, and lovelessness, is, for naturalists, a fiction.

Must we then, as Christians, be anti-science in order to avoid the dangers poised by naturalism? Not at all. Christians have long held (rooted especially in the Thomistic tradition) that scientific naturalism is perfectly appropriate for the natural sciences. Science can tell us much of the world—how it originated, how it fits together, where it is headed. The laws of nature that scientists study are laws created by God and hence are very, very good.

But just because a scientist is committed to scientific naturalism, she need not commit herself also to metaphysical naturalism, i.e., the belief that these natural laws are all that exist. More specifically, a Christian evolutionary biologist very committed to the principles of natural selection need not conclude that simply because evolution exist, God does not. As Nichols points out, some of the greatest scientists were also Christian (Galileo, Newton, Descartes, Pascal, Max Plank). The problem is not evolution (or any other natural “law”), but rather, when evolution becomes an all-encompassing philosophy. Science and theology are meant to be complementary, not antagonistic.

No, the solution for Christians, what Christians need to do if they are to survive the naturalist challenge, is not reject science (and hence the “natural”), but rather, they need to recover the supernatural. In a Christianity Today article, Hwa Yung writes on this,

A careful reading of the Bible and the sheer weight of empirical evidence eventually brought me back to a supernatural Christianity. In this, I found myself out of sync with much of Western theology. Here liberals were at least consistent, but not evangelicals. Most liberals denied the supernatural both in the Bible and in the present; evangelicals fought tooth and nail to defend the miraculous in the Bible, but rarely could cope with it in real life.

Now, Yung is writing about the recovery of a more charismatic Pentecostal form of Christianity, which I am not arguing for here, but his basic point is sound. Christians need to recover the idea of the miraculous, the realm beyond science, the invisible, the graced. To describe how this might take place liturgically or in other Christian practices is beyond the scope of one blog post (though I would love to hear your thoughts), but at the very least, Christians can recover the supernatural in conversation. We can admit that knowledge of God is beyond the capacity of reason. The natural world can lead us towards God, but true knowledge is a supernatural gift, elevating the intellect beyond what it is naturally capable of.

We can also admit that simply because knowledge of God is a gift, and one which we do not experience fully in this life (see 1 John 3:2 and 1 Corinthians 13:12 for when we can expect full knowledge), we can still do theology. In other words, we can still speculate about God, and even do so “scientifically.” Thomas Aquinas tells us

Sacred doctrine is a science. We must bear in mind that there are two kinds of sciences. There are some which proceed from a principle known by the natural light of intelligence, such as arithmetic and geometry and the like. There are some which proceed from principles known by the light of a higher science: thus the science of perspective proceeds from principles established by geometry, and music from principles established by arithmetic. So it is that sacred doctrine is a science because it proceeds from principles established by the light of a higher science, namely, the science of God and the blessed. Hence, just as the musician accepts on authority the principles taught him by the mathematician, so sacred science is established on principles revealed by God (I, Q. 1, art. 2).

For Aquinas, the object of this science is God, and its principles are the articles of faith (things like the Incarnation and the Trinity). Sacred Scripture is important, but is of itself neither the object nor the principle of theology:

Such are the Trinity of Persons in Almighty God [The Leonine Edition reads: The Three Persons, the omnipotence of God, etc.], the mystery of Christ’s Incarnation, and the like: and these are distinct articles of faith. On the other hand certain things in Holy Writ are proposed to our belief, not chiefly on their own account, but for the manifestation of those mentioned above: for instance, that Abraham had two sons, that a dead man rose again at the touch of Eliseus’ bones, and the like, which are related in Holy Writ for the purpose of manifesting the Divine mystery or the Incarnation of Christ: and such things should not form distinct articles (II-II, Q. 1, art. 6).

And in the end, although theology is a matter of disputation (I, Q. 1, art. 8), it ultimately does not get us knowledge of God, but only a certain knowledge of God’s effects, and how those effect pertain to our salvation:

Although we cannot know in what consists the essence of God, nevertheless in this science we make use of His effects, either of nature or of grace, in place of a definition, in regard to whatever is treated of in this science concerning God; even as in some philosophical sciences we demonstrate something about a cause from its effect, by taking the effect in place of a definition of the cause.

Ultimately, the point of theology is not to render God understandable or to possess God, but rather, to seek a mysterious God in love. And when we talk of God (or do theology), it should be this gifted love that we communicate, especially to our friends in the natural sciences. We do not have to make Christianity “natural” in order to speak to scientists. We need rather to speak confidently, humbly, and reverently about the supernatural, and listen to what the sciences have to say about the natural. Maybe, with a little grace, we can actually get a conversation going in which the scientist learns a little about grace and eternal life, and the Christian learns a little about the world.

And this brings us back to naturalism. In terms of religion, naturalism pushes us to make all matters of faith matters of natural science. The Bible becomes an anthropological and sociological document, sacraments become merely rituals, God becomes an idea, and the afterlife becomes a naiveté. Christianity becomes a voluntary association that anybody can “do,” like the girl in the opening story of this post, rather than a graced invitation into a relationship with God. Terence Nichols expresses well the appropriate Christian response:

The greatest gifts of grace are faith, hope, and the love of God (1 Cor. 13) which, Paul tells us, is poured into our hearts by the Holy Spirit that is given to us (Rom. 5:5). It is this love that allows us to love others, even enemies, and that characterizes the converted Christian life. Such a love is beyond our natural abilities. . . Christianity is not about rules and laws, guilt and fear of punishment, or extrinsic rewards. It is about grace: the experience of God’s transforming love and power in our lives that elevates and perfects our natural abilities and allows us to do more that we thought possible. In this sense, the life of every fully converted Christian moves beyond naturalism. It is god’s grace that makes the Christian practice of everyday life possible. And it is this same power of grace that one day will bring us to the resurrection, the ultimate transformation of nature, and to eternal life with God (226-27).

Thomas Aquinas’ Views Featured in TIME Magazine

I am delighted with the feature article for the most recent Time Magazine.  I love it when an article substantiating everything Thomas Aquinas said 800 years is considered “news.”  The Time Magazine article is all about happiness, which I talked about here in my article on beatitude as providing the foundation of Aquinas’ ethics.  This article, however, is not so much about ethics but rather, positive psychology, which I also talked about here.

Positive psychologists are interested  not just in what makes us depressed, but also in what makes us happy.  Or as Martin Seligman, the new president of the American Psychological Association, describes the goal of positive psychology: “It wasn’t enough for us (psychologists) to nullify disabling conditions and get to zero. We needed to ask, What are the enabling conditions that make human beings flourish? How do we get from zero to plus five?”  Seligman and others like Edward Diener, Ray Fowler, and Mihaly Csikszentmihalyi have been pushing scientific studies to determine what makes us happy, but for a Thomist, the conclusions are not news.

Turns out, wealth doesn’t make us happy.  As described by this accompanying Time Magazine article, scientific research indicates that people with above-average incomes are not much happier than others and that loss of wealth is usually only accompanied by a short term loss in happiness, if overal happiness is affected at all.

But Aquinas already said that happiness did not reside in the acquiring of wealth (I-II, Q. 2, art. 1) because wealth is meant to serve something else like the satisfaction of needs.  Even wealth that buys us not just what we need but all the things in the world that we may want does not satisfy our insatiable human appetites, as Aquinas explains:

in the desire for wealth and for whatsoever temporal goods . . . when we already possess them, we despise them, and seek others: which is the sense of Our Lord’s words (John 4:13): “Whosoever drinketh of this water,” by which temporal goods are signified, “shall thirst again.” The reason of this is that we realize more their insufficiency when we possess them: and this very fact shows that they are imperfect, and the sovereign good does not consist therein.

Positive psychologists are also discovering that education, fame, goods of the body, and even pleasure don’t make us happy.  All of Question 2 of the Prima Secundae, however,  is dedicated to proving this exact fact.

Positive psychologists have also discovered that friends are conducive to happiness.  Aquinas derives this notion from Aristotle, making this insight even more ancient:

If we speak of the happiness of this life, the happy man needs friends, as the Philosopher says (Ethic. ix, 9), not, indeed, to make use of them, since he suffices himself; nor to delight in them, since he possesses perfect delight in the operation of virtue; but for the purpose of a good operation, viz. that he may do good to them; that he may delight in seeing them do good; and again that he may be helped by them in his good work. For in order that man may do well, whether in the works of the active life, or in those of the contemplative life, he needs the fellowship of friends (I-II, Q. 4, art. 8 )

Religion also seems to make us  happier, which I talked about here.

But it also turns out that even the happiest people are sad some of the time.  According to Aquinas, this is because the happiness of this life is only imperfect happiness.  True happiness consists only in contemplating the Divine Essence, which is the only sort of happiness that cannot be lost.

Like I say, I am delighted that positive psychology is confirming all of these great Thomistic insights.  As valuable as positive psychology is, however, it can only tell us about imperfect happiness, which by its very nature will always be a little dissatisfying.  Maybe those like Martin Seligman and Edward Diener who are on the quest for happiness will, in their dissatisfaction with what positive psychology concludes, lead others to the theology of Thomas Aquinas which concludes that “final and perfect happiness can consist in nothing else than the vision of the Divine Essence” (I-II,  Q. 3, art. 8).
