Is Atheism Irrational?

By GARY GUTTING,

This is the first in a series of interviews about religion that I will conduct for The Stone. The interviewee for this installment is Alvin Plantinga, an emeritus professor of philosophy at the University of Notre Dame, a former president of both the Society of Christian Philosophers and the American Philosophical Association, and the author, most recently, of “Where the Conflict Really Lies: Science, Religion, and Naturalism.”

Gary Gutting: A recent survey by PhilPapers, the online philosophy index, says that 62 percent of philosophers are atheists (with another 11 percent “inclined” to the view). Do you think the philosophical literature provides critiques of theism strong enough to warrant their views? Or do you think philosophers’ atheism is due to factors other than rational analysis?

Alvin Plantinga: If 62 percent of philosophers are atheists, then the proportion of atheists among philosophers is much greater than (indeed, is nearly twice as great as) the proportion of atheists among academics generally. (I take atheism to be the belief that there is no such person as the God of the theistic religions.) Do philosophers know something here that these other academics don’t know? What could it be? Philosophers, as opposed to other academics, are often professionally concerned with the theistic arguments — arguments for the existence of God. My guess is that a considerable majority of philosophers, both believers and unbelievers, reject these arguments as unsound.

Still, that’s not nearly sufficient for atheism. In the British newspaper The Independent, the scientist Richard Dawkins was recently asked the following question: “If you died and arrived at the gates of heaven, what would you say to God to justify your lifelong atheism?” His response: “I’d quote Bertrand Russell: ‘Not enough evidence, God! Not enough evidence!’” But lack of evidence, if indeed evidence is lacking, is no grounds for atheism. No one thinks there is good evidence for the proposition that there are an even number of stars; but also, no one thinks the right conclusion to draw is that there are an uneven number of stars. The right conclusion would instead be agnosticism.

In the same way, the failure of the theistic arguments, if indeed they do fail, might conceivably be good grounds for agnosticism, but not for atheism. Atheism, like even-star-ism, would presumably be the sort of belief you can hold rationally only if you have strong arguments or evidence.
