In "Reason and Belief in God," I suggested that such propositions as:
1. God is speaking to me.
This is important for the following reason. In arguing that belief in God is properly basic, I meant to rebut the claim made by the evidentialist objector: the claim that the theist who has no evidence for theism is in some way irrational. What the evidentialist objector objects to, however, is not just believing in God without having a response to such objections to theism as the argument from evil. He concedes that the theist may perfectly well have an answer to that objection and to others; but as long as she has no evidence for the existence of God, he says, she can't rationally believe. As the evidentialist objector thinks of evidence, then, you don't have evidence for a belief just by virtue of refuting objections against it; you must also have something like an argument for the belief, or some positive reason to think that the belief is true. I think this conception of evidence is an appropriate conception; but in any event it is the relevant conception, since it is this conception of evidence that the evidentialist objector has in mind in claiming that the theist without evidence is irrational.
As I see it, then propositions like (1) - (3) are properly basic for many persons, including even such intellectually sophisticated adults as you and I. Quinn disagrees: " . . . I conclude that many, perhaps most, intellectually sophisticated adult theists in our culture are seldom if ever, in conditions which are right for propositions like those expressed by (1) - (3) to be properly basic for them." Why so? I think Quinn is inclined to agree, first, that there are conditions in which such beliefs are properly basic for a person; such conditions might be those of a child brought up by believing parents, or perhaps of an adult in a culture in which skeptics had not produced the sorts of alleged reasons for rejecting theistic belief that are at present fashionable. The problem for intellectually sophisticated adults in our culture, he says, is that many potential defeaters of theistic belief are available; and we have substantial reason to think them true. One kind of defeater for a belief (the kind Quinn is concerned with here) is a proposition incompatible with the belief; Quinn cites
4. God does not exist
There are defeaters for theistic belief, then; and in the presence of defeaters, an otherwise properly basic belief may no longer be properly basic. More exactly, according to Quinn
it seems plausible to suppose that conditions are right for propositions like those expressed by (1) - (3) to be . . . properly basic for me only if (i) either I have no sufficiently substantial reason to think that any of their potential defeaters is true, or I do have some such reason, but for each such reason I have, I have an even better reason for thinking the potential defeater in question is false, and (ii) in either case my situation involves no epistemic negligence on my part.Quinn goes on to say that he is not in this fortunate condition with respect to theistic belief; he knows of substantial reasons, he says, to think that (4) is true, and it is not the case that for each such reason he has, he has an even better reason for thinking (4) false. So (by Q*) belief in God is not properly basic for him; and he suspects the same goes for most of the rest of us.
Now here I find myself in solid disagreement. We must first ask what are these "very substantial reasons" for thinking that what (4) expresses is true. What would be some examples of such substantial reasons for atheism? Quinn's answer: "After all, nontrivial atheological reasons, ranging from various problems of evil to naturalist theories according to which theistic belief is illusory or merely projective, are a pervasive, if not obtrusive, component of the rational portion of our intellectual heritage."[6 ] So these substantial reasons for thinking theism false would be the atheological argument from evil together with theories according to which theistic belief is illusory or merely projective; here perhaps Quinn has in mind Marxist and Freudian theories of religious belief.
I should remark immediately that the Marxist and Freudian theories he alludes to don't seem to be even reasonably cogent if taken as reasons for believing (4), or as evidence for the nonexistence of God, or as reasons for rejecting belief in God. Freud's jejune speculations as to the psychological origin of religion and Marx's careless claims about its social role can't sensibly be taken as providing argument or reason for (4) , i.e., for the nonexistence of God; so taken they present textbook cases (which in fact are pretty rare) of the genetic fallacy. If such speculations and claims have a respectable role to play, it is instead perhaps that of providing a naturalistic explanation for the wide currency of religious belief, or perhaps that of attempting to discredit religious belief by tracing it to a disreputable source. But of course that doesn't constitute anything like evidence for (4) or a reason to think theism false. One might as well cite as evidence for the existence of God St. Paul's claim (Romans 1) that failure to believe in God is a result of sin and rebellion against God. None of the naturalistic theories according to which theism is illusory or merely projective seem to me to have any strength at all as arguments or evidence for the nonexistence of God-although they may be of interest in other ways.
This leaves us with the atheological argument from evil as the sole substantial reason for thinking (4) true. And initially this argument seems much stronger as a reason for rejecting theistic belief. But is it really? Until recently, most atheologians who urged an atheological argument from evil held that
5. God exists and is omniscient, omnipotent, and wholly good
6. there are 10 turps of evil
So first, these alleged substantial reasons for rejecting theism warrant a good deal of skepticism. But secondly, even if we concede that there are such reasons, Quinn's conclusion won't follow; this is because (Q*), as it stands, is pretty clearly false. The suggestion is that if I have a substantial reason for thinking some defeater of a proposition (for example, it's denial) is true, then I can't properly take the proposition as basic unless I have an even stronger reason for thinking the defeater in question false. But surely this is to require too much. Suppose an atheologian gives me an initially convincing argument for thinking that (5) is in fact extremely unlikely or improbable on (6). Upon grasping this argument, perhaps I have a substantial reason for accepting a defeater of theistic belief, namely that (5) is improbable on (6). But in order to defeat this potential defeater, I need not know or have very good reason to think that it is false that (5) is improbable on (6); it would suffice to show that the atheologian's argument (for the claim that (5) is improbable on (6)) is unsuccessful. To defeat this potential defeater, all I need to do is refute this argument; I am not obliged to go further and produce an argument for the denial of its conclusion. Quinn takes
(4) God does not exist
to be a potential defeater for the propositions (1) - (3); but to defeat the potential defeater offered by an argument for (4) I need not necessarily have some argument for the existence of God. There are undercutting defeaters as well as rebutting defeaters.
There is another and more subtle point here. Quinn seems to be thinking along the following lines: suppose I take some proposition as basic, but have substantial evidence from other things I believe for some defeater of this proposition-a proposition incompatible with it, let's say. Then (according to Q*) I am irrational if I continue to accept the proposition in question, unless I also have good evidence for the falsehood of the defeater. So if I accept a proposition p, but believe or know other things that constitute strong evidence of some defeater q of p, then, says Q*, if I am not to be irrational in continuing to accept p as basic, I must have a reason for thinking q false, a reason that is stronger than the reasons I have for thinking q true.
Now my question is this: could p itself be my reason for thinking q false? Or must that reason be some proposition distinct from p? Consider an example. I am applying to the National Endowment for the Humanities for a fellowship; I write a letter to a colleague, trying to bribe him to write the Endowment a glowing letter on my behalf; he indignantly refuses and sends the letter to my chairman. The letter disappears from the chairman's office under mysterious circumstances. I have a motive for stealing it; I have the opportunity to do so; and I have been known to do such things in the past. Furthermore an extremely reliable member of the department claims to have seen me furtively entering the chairman's office at about the time when the letter must have been stolen. The evidence against me is very strong; my colleagues reproach me for such underhanded behavior and treat me with evident distaste. The facts of the matter, however, are that I didn't steal the letter and in fact spent the entire afternoon in question on a solitary walk in the woods; furthermore I clearly remember spending that afternoon walking in the woods. Hence I believe in the basic way
7. I was alone in the woods all that afternoon, and I did not
steal the letter.
So I take (7) as basic; but I have a substantial reason to believe a defeater of (7). According to Q*, if I am to be rational in this situation, I must have even better reason to believe that this potential defeater is false. Do I? Well, the only reason I have for thinking this potential defeater false is just (7) itself; I don't have any independent reason to think the defeater false. (The warrant I have for (7) is nonpropositional warrant; it is not conferred upon (7) by virtue of my believing that proposition on the basis of some other proposition, for I don't believe (7) on the basis of any other proposition.)
In this situation it is obvious, I take it, that I am perfectly rational in continuing to believe (7) in this basic way. The reason is that in this situation the positive epistemic status or warrant that (7) has for me (by virtue of memory) is greater than that conferred upon its potential defeater by the evidence I share with my colleagues. We might say that (7) itself defeats the potential defeater; no further reason for the denial of this defeater is needed for me to be rational. Suppose we say that in this sort of situation a proposition like (7) is an intrinsic defeater of its potential defeater. When a basic belief p has more by way of warrant than a potential defeater q of p, then p is an intrinsic defeater of q-an intrinsic defeater-defeater, we might say. (A belief r is an extrinsic defeater-defeater if it defeats a defeater q of a belief p distinct from r.)
So my question here is this: how is Quinn thinking of these reasons for thinking the defeating proposition false? I am inclined to believe that he intends Q* to be read in such a way that these reasons have to be extrinsic defeater-defeaters; but if so, then his principle, I think, is clearly false. On the other hand, perhaps it is to be understood as saying something like
Q** If you believe p in the basic way and you have reason to believe a defeater q of p, then if you are to be rational in continuing to believe p in this way, p must have more warrant for you then q does.
I am not certain this principle is correct, but I am also not inclined to dispute it. The central point to see, however, is that if a belief p is properly basic in certain circumstances, then it has warrant or positive epistemic status in those circumstances in which it is properly basic-warrant it does not get by virtue of being believed on the evidential basis of other propositions. (By hypothesis it is not believed on the evidential basis of other propositions.) To be successful, a potential defeater for p must have as much or more warrant as p does. And p can withstand the challenge offered by a given defeater even if there is not independent evidence that serves either to rebut or undercut the defeater in question; perhaps the nonpropositional warrant that p enjoys is itself sufficient (as in the above case of the missing letter) to withstand the challenge.
But how does all this apply in the case in question, the case of belief in God and the alleged defeaters Quinn mentions? As follows. If there are circumstances in which belief in God is properly basic, then in those circumstances such belief has a certain degree of warrant or positive epistemic status. Now suppose a potential defeater arises: someone claims that the existence of 10 turps of evil makes theism improbable, or he claims that theistic belief arises out of nothing more reputable than a kind of widespread human neurosis. Two questions then arise. First, how does the degree of nonpropositional warrant enjoyed by your belief in God compare with the warrant possessed by the alleged potential defeater? It could be that your belief, even though accepted as basic, has more warrant than the proposed defeater and thus constitutes an intrinsic defeater-defeater. When God spoke to Moses out of the burning bush, the belief that God was speaking to him, I daresay, had more by way of warrant for him than would have been provided for its denial by an early Freudian who strolled by and proposed the thesis that belief in God is merely a matter of neurotic wish-fulfillment. And secondly, are there any extrinsic defeaters for these defeaters? Someone argues that the existence to 10 turps of evil is inconsistent with the existence of God; I may then have an extrinsic defeater for this potential defeater. This defeater-defeater need not take the form of a proof that these propositions are indeed consistent; if I see that the argument is unsound, then I also have a defeater for it. But I needn't do even that much to have a defeater. Perhaps I am no expert in these matters but learn from reliable sources that someone else has shown the argument unsound; or perhaps I learn that the experts think it is unsound, or that the experts are evenly divided as to its soundness. Then too I have or may have a defeater for the potential defeater in question, and can continue to accept theistic belief in the basic way without irrationality.
By way of conclusion then: Quinn claims that intellectually sophisticated adult theists in our culture are seldom in epistemic circumstances in which belief in God is properly basic; for they have substantial reason to think that some potential defeater of theism is true, and do not have, for each such defeater, even stronger reason to think it is false. But first, it isn't necessary that they have reasons independent of their belief in God for the falsehood of the alleged defeaters. Perhaps the nonpropositional warrant enjoyed by your belief in God is itself sufficient to turn back the challenge offered by the alleged defeaters, so that your theistic belief is an intrinsic defeater-defeater. And second, extrinsic defeaters of the alleged defeaters need not be evidence for the falsehood of those defeaters; they may instead undercut the alleged defeaters; they may be, for example, refutations of atheological arguments. (And here Christian philosophers can clearly be of service to the rest of the Christian community.) My opinion (for what it is worth) is that for many theists, the nonpropositional warrant belief in God has for them is indeed greater than that of the alleged potential defeaters of theistic belief- for example, Freudian or Marxist theories of religion. Furthermore, there are powerful extrinsic defeaters for the sort of potential defeaters of theism Quinn suggests. The atheological argument from evil, for example, is formidable; but there are equally formidable defeaters for this potential defeater. I am therefore inclined to believe that belief in God is properly basic for most theists-even intellectually sophisticated adult theists.

I owe these terms to John Pollock. The distinction between undercutting and rebutting defeaters is of central importance to apologetics. If the propriety of basic belief in God is threatened by defeaters, there are two ways to respond. First, there is negative apologetics: the attempt to refute the arguments brought against theism (the atheological argument from evil, the claim that the conception of God is incoherent, and so on). Second, there is positive apologetics: the attempt to develop arguments for the existence of God. These are both important disciplines; but it is only the first, clearly enough, that is required to defeat those defeaters.
