I don’t think that the humanities or the liberal arts can be defended, at least not in the sense that most people give to “defended.” Here’s why, starting with three texts on which I will build my explanation.
The English theologian Austin Farrer used to say that some Christian doctrines — he was thinking especially of the hypostatic union — cannot be defended, but can be homiletically expounded.
Similarly, in Whose Justice? Which Rationality? Alasdair MacIntyre writes,
In systematizing and ordering the truths they take themselves to have discovered, the adherents of a tradition may well assign a primary place in the structures of their theorizing to certain truths and treat them as first metaphysical or practical principles. But such principles will have had to vindicate themselves in the historical process of dialectical justification… Such first principles themselves, and indeed the whole body of theory of which they are a part, themselves will be understood to require justification. The kind of rational justification which they receive is at once dialectical and historical. They are justified insofar as in the history of this tradition they have, by surviving the process of dialectical questioning, vindicated themselves as superior to their historical predecessors.
And in The Abolition of Man C. S. Lewis writes,
Those who understand the spirit of the Tao and who have been led by that spirit can modify it in directions which that spirit itself demands. Only they can know what those directions are. The outsider knows nothing about the matter. His attempts at alteration, as we have seen, contradict themselves. So far from being able to harmonize discrepancies in its letter by penetration to its spirit, he merely snatches at some one precept, on which the accidents of time and place happen to have riveted his attention, and then rides it to death — for no reason that he can give. From within the Tao itself comes the only authority to modify the Tao. This is what Confucius meant when he said ‘With those who follow a different Way it is useless to take counsel’. This is why Aristotle said that only those who have been well brought up can usefully study ethics: to the corrupted man, the man who stands outside the Tao, the very starting point of this science is invisible. He may be hostile, but he cannot be critical: he does not know what is being discussed…. Outside the Tao there is no ground for criticizing either the Tao or anything else.
I think that these passages, read rightly, suggest a few things. First, that it’s probably impossible to defend the artes liberales, or the studia humanitatis, to people who are firmly outside their Tao — who simply do not acknowledge the value of the foundational commitments that have shaped the tradition. The person who relentlessly demands to know what kind of job a liberal-arts education will get him “may be hostile, but he cannot be critical.” And this is not a temporary or trivial impediment that can be maneuvered around; it’s an immoveable object.
But apologetics is not the only mode of suasion. In some cases the more appropriate rhetoric relies on narration and exposition: perhaps something as simple as telling the story of what we do. There are many places around the country where older models of the humanities are flourishing, even as those who have rejected this Tao are floundering — those older models having, as it were, vindicated themselves as superior to their historical successors, or would-be successors. But what happens in these institutions, in these classrooms, is simply invisible to people who question the value of the humanities. Rendering the invisible visible might be one of the best services those of us following those models could perform in “defense” of our practices.
I’m teaching a class called Philosophy Versus Literature and right now we’re working through Lucretius. Yesterday we talked about philosophy as therapy — drawing on Martha Nussbaum, among others — and the odd but, in the end, strong logic that leads Lucretius (following Epicurus) to believe that physics is first philosophy, that understanding the constitution of the world is the necessary first step towards being liberated from fear and unnecessary pain. Next time I’m going to tell the students about Stephen Greenblatt’s (very bad) book The Swerve, and ask them why a book about the early modern recovery of Lucretius became a bestseller and award-winner in 21st-century America. These conversations concern matters ancient and permanent and are also about as relevant as relevant can be, if that happens to be one of your criteria for educational value. Moreover, De Rerum Natura is a book that runs pretty strongly against the grain of all that my students believe and hope — but that does not deter them nor me from treating it with the utmost attentiveness.
I can’t defend the value of this kind of exercise in some kind of abstract, characterless intellectual space; nor am I inclined to. It makes sense within the Tao; and if you want to see what kind of sense it makes you have to think and act within the Tao. You have to take it on as a living option, not a dessicated proposition. To those who doubt the value of what I do, I probably have little more to say than: Taste and see. (But I’ll use more words to say it.)
