An edited version of this post, first published here five years ago today, forms the first half of Chapter 5 of Philosophy after Christ: Thinking God’s Thoughts after Him. The post linked in the first paragraph appeared on Bill Vallicella’s blog in 2018 (therefore, more than “a few months ago”).—A.G.F.
In a short post few months ago, Bill Vallicella argued that “If God exists, and one is an atheist, then one is ignorant of God, but it does not follow that one is culpably ignorant.” (Italics added.)
Bill takes his definition of “culpable ignorance” from a Catholic dictionary: ignorance is blameworthy if the ignorant one could have “cleared up” his ignorance, but chose not to. “One is said to be simply (but culpably) ignorant,” the dictionary says, “if one fails to make enough effort to learn what should be known.”
Bill applies this to the atheist this way:
I hold that there is vincible ignorance on various matters. But I deny that atheists are vincibly ignorant. Some might be, but not qua atheists. Whether or not God exists, one is not morally culpable for denying the existence of God. Nor do I think one is morally culpable if one doubts the existence of God.
Bill acknowledges that his exculpation of the professing atheist “puts me at odds with St. Paul, at least on one interpretation of what he is saying at Romans 1: 18-20.”
I’ll say! As Bill wrote in the post he linked to: “There are sincere and decent atheists, and they have plenty of excuse for their unbelief. The best of them, if wrong in the end, are excusably wrong.”
That position reveals a great deal about Bill’s idea of God. It’s not the idea one gets from the Bible, arguably the source of what Bill calls “the Judeo-Christian tradition.” I bring this up because Bill stipulates (in the post under discussion) that for “present purposes, it suffices to say that ‘God’ refers to the supreme being of the Judeo-Christian tradition.”
For Bill’s argument to work, that interpretation of Romans 1:18-20—God infallibly communicates His existence, power, and divinity to all people and they are all responsible for having received that communication—would have to fall outside that “tradition.”
God’s Word is the light that enlightens everyone who comes into the world (John 1:9). There are no exceptions for professing atheists.
