Peter van Inwagen on disciplinary hubris, relevant expertise, expectations of deference, and ordinary prudence

In the early 1990s the philosopher Peter van Inwagen wrote an essay called "Critical Studies of the New Testament and the User of the New Testament." It is a long, detailed philosophical investigation of the epistemic nature, or status, of academic biblical scholarship; specifically, it asks whether ordinary Christians or readers of the Bible ought to consult such scholarship, or defer to its judgments, prior to or in the course of their readings of the Bible or accompanying theological judgments. After many pages, his answer is a firm No. Here are the final paragraphs of the essay (bolded emphases are mine):

I conclude that there is no reason for me to think that Critical Studies have established that the New Testament narratives are historically unreliable. In fact, there is no reason for me to think that they have established any important thesis about the New Testament. I might, of course, change my mind if I knew more. But how much time shall I devote to coming to know more? My own theological writings, insofar as they draw on contemporary knowledge, draw on formal logic, cos­mology, and evolutionary biology. I need to know a great deal more about these subjects than I do. How much time shall I take away from my study of them to devote to New Testament studies (as opposed to the study of the New Testament)? The answer seems to me to be: very little. I would suggest that various seminaries and divinity schools might consider devoting a portion of their curricula to these subjects (not to mention the systematic study of the Fathers!), even if this had to be done at the expense of some of the time currently devoted to Critical Studies.

 Let me close by considering a tu quoque. Is not philosophy open to many of the charges I have brought against Critical Studies? Is not philosophy argument without end? Is not what philosophers agree about just precisely nothing? Are not the methods and arguments of many philosophers (especially those who reach extreme conclusions) so bad that an outsider encountering them for the first time might well charitably conclude that he must be missing something? Must one not devote years of systematic study to philosophy before one is competent to think philosophically about whether we have free will or whether there is an objective morality or whether knowledge is possible?—and yet, is one not entitled to believe in free will and knowledge and morality even if one has never read a single page of philosophy?

Ego quoque. If you are not a philosopher, you would be crazy to go to the philosophers to find anything out—other than what it is that the philosophers say. If a philosopher tells you that you must, on methodological grounds, since he is the expert, take his word for something—that there is free will, say, or that morality is only convention—you should tell him that philosophy has not earned the right to make such demands. Philosophy is, I think, valuable. It is a good thing for the study of philosophy to be pursued, both by experts and by amateurs. But from the premise that it is a good thing for a certain field of study to be pursued by experts, the conclusion does not follow that that field of study comprises experts who can tell you things you need to attend to before you can practice a religion or join a political party or become a conscientious objector. And from the premise that it is a good thing for a certain field of study to be pursued by amateurs, the conclusion does not follow that anyone is under an obligation to become an amateur in that field.

This is very close to some of the depreciatory statements I have made about the authority of Critical Studies. Since I regard philosophy as a Good Thing, it should be clear that I do not suppose that my arguments lend any support to the conclusion that the critical study of the New Testament is not a Good Thing. Whether it is, I have no idea. I don't know enough about it to know whether it is. I have argued only that the very little I do know about Critical Studies is sufficient to establish that users of the New Testament need not—but I have said nothing against their doing so—attend very carefully to it. (God, Knowledge, and Mystery [Ithaca: Cornell University Press, 1995], 189–190)

The choice quote here, reduced to a general maxim:

If an [expert in X] tells you that you must, on methodological grounds, since he is the expert, take his word for something, you should tell him that [X] has not earned the right to make such demands.

One cannot substitute just anything for "X," but one can substitute most things, and certainly anything outside the hardest of hard disciplines. Any and all discursive practices and realms of knowledge in which prudence is required or normative questions are involved, or in which ongoing contestation, adjudication, and dissent are prominent or at least typical, are by definition substitutable for "X." Moreover, if a legitimate expert in X attempts to mandate deference to her authority, but in this case regarding not X but Y, the attempt is patently fallacious, mendacious, confused, and absurd. One owes such an attempt and such an expert little more than an eye-roll, though laughter and mockery are warranted.

Let the reader understand.
