Belief without Proof: Is Belief in God Rational if there is no Evidence? Part III

April 7th, 2009 by Matt

In Part I of this series, I criticised the rationalist objection to belief in God. In Part II I set out an alternative view of faith and reason defended by Alvin Plantinga. In this final post, I want to address two common objections to the view of faith and reason I have been sketching.

Argument is irrelevant
One argument Martin suggests is more of a statement. He claims that by classing certain theological beliefs as basic one puts those beliefs beyond rational appraisal. Once a belief is declared basic, one cannot rationally evaluate it.

This objection is incorrect. As noted above, a belief is properly basic only if no defeaters are forthcoming for it. Consequently, the belief is not immune to argument. Sceptics could offer rebutting defeaters of theological beliefs, give arguments to the claim that theism is false or they could argue that the concept of God is incoherent or inconsistent. Further, sceptics could offer undercutting defeaters that the grounds that produce theological beliefs are questionable. The assessment of such objections would be vital to determining the rationality of belief in God.

There are further ways sceptics and believers can engage in dialogue. One could point out inconsistencies or incoherence in a person’s belief set, even if one does not accept the beliefs in question. One can grant a proposition held by one’s opponents for the sake of argument and then point out its implications, show that these implications or the beliefs themselves entail things that the person themself rejects or considers absurd. Further, one can show that the views one person holds follow from beliefs his opponent holds and so his opponent has good reasons for accepting these beliefs and so on.

Finally, as I noted above properly basic beliefs are foundational beliefs. A foundation needs to be able to support the structure which is built upon it. One important question, then, is to ask what happens if you take a belief as basic, can one reason from it to find plausible, coherent and defensible answers to the various existential and philosophical questions that we use basic beliefs to assist us in answering. C S Lewis put the point well when he stated, “I believe the sun has risen, not because I can see the sun, but because with it I can see everything else.”[1]

The Great Pumpkin
Perhaps the most common objection to Christians taking belief in God as properly basic belief is what is called “the Great Pumpkin objection.” Plantinga himself cites this argument,

If belief in God is properly basic, why cannot just any belief be properly basic? Could we not say the same for any bizarre aberration we think of? What about voodoo or astrology? What about the belief that the Great Pumpkin returns every Halloween? Could I properly take that as basic? Suppose I believe that if I flap my arms with sufficient vigour, I can take off and fly around the room; could I defend myself against the charge of irrationality by claiming this belief is basic? If we say belief in God is properly basic, will we not be committed to holding that just anything, or nearly anything, can be properly taken as basic, thus throwing wide the gates to irrationalism and superstition?[2][Emphasis added]

A particularly succinct articulation of this objection is made by Keith Parsons, who offers the following reductio ad absurdum of Plantinga’s position,[3]

(1) “God exists” is a properly basic belief for Christians. (assumption for reductio)

(2) If “God exists” is a properly basic belief for Christians, then innumerable patently irrational beliefs are properly basic for the groups that endorse them.

(3) Innumerable patently irrational beliefs are properly basic for the groups that endorse them. (from 1 and 2 by modus ponens)

(4) But this is absurd.

(5) Therefore: The assumption “God exists’ is a properly basic belief for Christians” must be rejected.

Parsons notes, correctly, that this argument hinges on (2) and (4). I agree; however, unlike Parsons, I think these premises are not as well established as he thinks.

Turning to (2), Parsons suggests that for any argument used by a Christian to justify the claim that belief in God is properly basic there exists an analogous argument for patently irrational beliefs. This, however, is mistaken. I noted above that basic beliefs, even ones that entail the existence of God, are properly basic in certain circumstances. First, they were typically based on grounds, either perceptual or doxastic. Second, they were justified only if there exists no defeaters for them.

Patently irrational beliefs do not meet these criteria. The reason Parsons’ appeals to patently irrational beliefs is because anyone can see on reflection that they are absurd. But if one can see that a belief is absurd then it is unlikely that it will be a belief that seems true to that person. Moreover, if it is obviously absurd then there exists a defeater for it. One will see that it entails an obviously absurd conclusion; itself.

If we turn to premise (4) another problem arises. Parsons takes it as absurd that a “patently irrational belief” can be rational. This is true if the word “rational” is used in the same sense both times it occurs in this statement. It is not true if the word “rational” is used in different senses. It is not absurd for a belief to be irrational in one sense and yet rational in another sense.

We need to ask, then, what sense of rational Parsons has in mind. Now in order for his argument to follow from (1), the word “rational” must be used in an internalist sense. This is because that is how the term is used by Plantinga when he argues that, in specific circumstances, belief in God can be properly basic.

The problem is that in this sense it is not clear that the claim that the kind of beliefs Parsons refers to are always irrational. Take an example Parsons himself cites, Voodoo. Suppose that a person suffers from some mental disorder which causes her to hallucinate and have a vivid experience, such that, it seems obvious to her that Voodoo is true. Moreover, suppose further, that she has no reason to doubt this experience. She is not aware it is a hallucination and is not aware of an argument against the truth of what she perceives. It seems clear that such a person is rational in the internalist sense, she is not acting irresponsibly given the information available to her. Of course her belief is irrational in an externalist sense, it is caused by brain disorder; and hence, is based on an unreliable process. But this externalist sense is not the sense Plantinga uses when he argues that belief in God is rational in the absence of evidence.

Perhaps Parsons means to use rational in the externalist sense and his position is that it is absurd to claim that Voodoo could ever be rational in this sense; only a person suffering from a hallucination or mental impairment could actually have experiences such that Voodoo was obvious and fail to see the force of argument. If this is what Parsons means then (4) may well be true, the problem now is that it is false to suggest that an analogue of Plantinga’s argument shows that Voodoo is rational. Plantinga argued that a basic belief in God is externally rational only if it is based on reliable ground and a hallucination is not a reliable ground.

Conclusion
I have argued that the rationalist position, that belief in God is irrational in the absence of proof, is incoherent. I have sketched a way of looking at faith and reason under which one is rational in believing in God independently of proof and have defended it against two objections.

Let me finish by citing from Alvin Plantinga’s famous advice to Christian philosophers,

We come to philosophy with a range of opinions about the world and humankind and the place of the latter in the former; and in philosophy we think about these matters, systematically articulate our views, put together and relate our views on diverse topics, and deepen our views by finding unexpected interconnections and by discovering and answering unanticipated questions. Of course we may come to change our minds by virtue of philosophical endeavor; we may discover incompatibilities or other infelicities. But we come to philosophy with prephilosophical opinions; we can do no other. And the point is: the Christian has as much right to his prephilosophical opinions, as others have to theirs. He needn’t try first to ‘prove’ them from propositions accepted by, say, the bulk of the non-Christian philosophical community; and if they are widely rejected as naive, or pre-scientific, or primitive, or unworthy of “man come of age,” that is nothing whatever against them. Of course if there were genuine and substantial arguments against them from premises that have some legitimate claim on the Christian philosopher, then he would have a problem; he would have to make some kind of change somewhere. But in the absence of such arguments-and the absence of such arguments is evident-the Christian philosophical community, quite properly starts, in philosophy, from what it believes.[4]

  • It never fails to amaze me that skeptics adopt Parson’s premise 2) with such ease, as though they think it’s acceptable to just assume that any number of false and absurd beliefs are held with just as much warrant as belief in God. That they don’t stop and think “Oh wait – that’s one of the very thinks in dispute here” is startling given the supposedly critical approach being taken by these qualified philosophers of religion.

    Recent blog post: Craig vs Hitchens

  • Keith Parsons emailed while I was writing my chapter on “Faith and Reason” for my book by saying something to the effect that if this was the first argument Plantinga ever wrote on he would be not be taken seriously as a philosopher, even by Christians.

  • Hi John

    Let’s just say I disagree with Parson’s here:

    In fact one of Plantinga’s earliest articles did defend the idea that belief in God was rational in the absence of proof this was of course the short paper “The Strategy of the Skeptic” published in 1964. Moreover the idea that belief in God was justified independently of proof was the conclusion of Plantinga’s earliest book God and Other Minds: A Study of the Rational Justification of Belief in God (1967) and people took God and Other minds very seriously. Quentin Smith for example writes:

    “ The secularization of mainstream academia began to quickly unravel upon the publication of Plantinga’s influential book on realist theism, God and Other Minds, in 1967. It became apparent to the philosophical profession that this book displayed that realist theists were not outmatched by naturalists in terms of the most valued standards of analytic philosophy: conceptual precision, rigor of argumentation, technical erudition, and an in-depth defense of an original world-view. This book, followed seven years later by Plantinga’s even more impressive book, The Nature of Necessity, made it manifest that a realist theist was writing at the highest qualitative level of analytic philosophy, on the same playing field as Carnap, Russell, Moore, Grünbaum, and other naturalists. Realist theists, whom hitherto had segregated their academic lives from their private lives, increasingly came to believe (and came to be increasingly accepted or respected for believing) that arguing for realist theism in scholarly publications could no longer be justifiably regarded as engaging in an “academically unrespectable” scholarly pursuit.” (The Metaphilosophy of Naturalism, Philo Vol 4 number 1)

    So it seems Plantinga’s earliest arguments were for this thesis and in fact lead to him being taken very seriously as a Philosopher the converse of what Parson’s affirms.

  • How about a more moderate version of the second objection? Rather than supposing that “patently irrational beliefs” are just as likely to be properly basic, why not focus instead on other religions?

    A Muslim could argue that (a) if Islam is true, then it is reasonable to expect Allah to personally tell them the “truths” of Islam, and (b) there are no known defeaters of Islam. As a Christian, you would probably reject (b), but if you were willing to use similar arguments to Christian apologists in defending against “apparent” contradictions, “apparent” brutality in the scriptures, etc, you might find that any attack against Islam could be brushed aside – at least in such a way that a committed Muslim could continue to “responsibly” remain a Muslim.

    Naturally, the previous paragraph could be adapted for Judaism, Mormonism, Hinduism, and any other religion. There are many, even if you just focus on the ones that are “plausible” enough to have attracted more than a million followers.

    Now this doesn’t automatically mean they are all wrong. But it raises a different problem, as I see it. If you are a reasonably conservative Christian, then you presumably believe that God will actually punish people from these other religions for eternity, for not being a Christian. (Please correct me if I’m wrong about this.) But if you accept that their beliefs could be properly basic – or even just that *they could responsibly believe* that their beliefs are properly basic – then it seems God would be punishing them for being just as rational and responsible as you, who presumably will be rewarded for eternity.

    I know this might seem like a bit of a rehash of the old “but there are so many religions; why should we believe yours is the true one?” argument. But I think that Plantinga’s willingness to lower the bar in terms of knowledge/rationality leaves the door open for too many things to be regarded as “knowledge”, including religions at odds with Christianity.
