It has been said by a great mind, that confusion is worse than error.¹ Erroneous statements and opinions, in their naked deformity, are generally too hideous to win the regard and confidence of men even in their present depraved condition; while the manifestation of what is true, in its simple grandeur and pure light, is often too bright and fair to be agreeable to the eye and the heart of man. The great work which a lover of truth finds to do, is to separate the conglomerate mass of knowledge, or what men call knowledge, into its two component parts, the true and the false. What is false owes all its plausibility and power to its being associated and mingled with what is true. What is true, is rendered dim and uncertain and weak by being blended and confounded with the erroneous. The human mind is like a thrashing-floor. The honest inquirer will be constantly using the fan, to separate the chaff from the wheat.

Alston notes two pillars that he believes, in tandem, support theistic belief: the general consideration of natural theology and the experience of God. For Alston, the latter bears the greater weight and he goes on to explore how such experience contributes appropriate epistemic support to theism.

In this essay I shall explore the possibilities for knowledge of God that are opened up by recent developments in epistemology that go under the title externalism; more specifically, I shall be concerned with the version of externalism known as reliabilism. I shall set this up with a consideration of how those possibilities look from a more internalist epistemological stance. I shall be working from within the Christian tradition, though I take my remarks to have a wider bearing.

If you take a poll in a typical Christian congregation, you will discover that the majority of church members have had very deep encounters with God. Most have had at least a few occasions of dramatic answer to prayer, some have seen physical healings of various sorts, and many have had moments when God was intensely real to them. Moreover, these phenomena happen not only to individual believers, they also occur when Christians gather together in community. Speaking more generally, it is safe to say that millions upon millions of people worldwide have had some sort of religious experience at one time or another. What should we make of these facts? Do they provide evidence for the existence of God? For the truth of Christianity? How is a naturalist supposed to take these facts?

In response to Robert A. Larmer, Basinger argues: "There is little basis upon which to claim that all proponents of solely natural causation are guilty of dogmatic, uncritical, question-begging reasoning. To claim emphatically that there is in fact no God (and thus no divine causal intervention) may be an unwarranted metaphysical contention. But the nontheist need not be making any such ontological claim. She can simply be saying that, while this epistemological contention is debatable, its affirmation is not necessarily any more dogmatic or question begging than the belief that the 'total' evidence makes theistic belief (and thus the possibility of divine intervention) most reasonable."

In an ongoing dialogue in this journal (Sophia), Robert Larmer and I have been discussing whether the undisputed occurrence of certain conceivable events — for instance, astonishing healings — could require all honest, thoughtful individuals to acknowledge that God has supernaturally intervened in earthly affairs. I have not denied that a theist (or nontheist) could justifiably consider the occurrence of certain possible (or even actual) events to be strong evidence for theism — for the existence of a God who benevolently intervenes in earthly affairs. But nontheists, I have argued, can justifiably maintain that evil — that the amount and nature of human pain and suffering — stands as strong evidence against God's existence. Furthermore, I have argued, nontheists can justifiably maintain that the evidence against God's existence generated by evil would outweigh any amount of evidence for theism that might be produced by any conceivable set of events. And for this reason I have continued to deny that there exists any conceivable context in which a person who did not acknowledge that God has intervened in earthly affairs could justifiably be accused of having conducted herself in a nonrational manner.
