My views have been changing pretty rapidly recently as I've been reading a lot of philosophy of religion, but here's a summary of what I think right now.
The Principle of Critical Trust
According to Swinburne's principle of credulity, what seems to be the case is probably the case in the absence of defeaters. So for example, if I have an experience in which I seem to see a car in my garage, I am justified in believing that there is a car in my garage. On the other hand, if when I move a pencil up and down it seems to bend, I am not justified in believing that the pencil is probably bending, because that claim is defeated by other evidence that I have about the nature of pencils.
I don't agree with the principle of credulity, because it's insufficiently rigorous. We need a number of qualifiers to make it viable. The most important such qualifier is the observation that when an experience is defeated, we rationally preserve the highest undefeated level of content from the experience.
For example, if I see a plane and you see a weather balloon when we look at the same location in the sky at the same time, both of our experiences are defeated. I have a defeater for my plane-experience, and you have a defeater for your weather-balloon-experience. However, just because both of our experiences are defeated, we don't conclude that there was nothing in the sky. We conclude that there was something in the sky, but we don't know what it was exactly.
I call the principle of credulity, when modified by this and a few other qualifiers, the principle of critical trust.
An Argument from Religious Experience
Billions of people have had religious experiences since before recorded history. Under the principle of critical trust, all of these experiences get prima facie justification. So Christian experiences get justification, as do Hindu experiences, Muslim experiences, and so forth. The problem is that these experiences conflict with one another. So, every religious experience has a defeater: the experiences of other contradictory religions.
Applying the qualifier to the principle of critical trust, though, we don't have to concede that any religious experience loses all of its justification. We just cancel out the differences between religious experiences to arrive at the "core" of all such experiences, which remains undefeated. This "core" includes a god and perhaps some lesser supernatural beings.
Therefore, I think that any rational person who is apprised of this argument is obligated to either provide a defeater for this "core" of all religious experiences or believe in a god. This defeater will have to be so strong that we cannot interpret any experience as being of a god. I suggest that the only defeater with that kind of strength will be some kind of argument from evil.
The Problem of Evil
One form of the problem of evil says that since it seems reasonable to assert that there is pointless evil, God probably does not exist. Another form says that the world we observe is better predicted by the hypothesis that the universe is indifferent to us than by the hypothesis that God exists and cares about us. A final form of the problem of evil claims that an all-good, all-powerful God is logically incompatible with the existence of evil.
In the context of my argument from religious experience, the first two forms of the problem of evil attempt to pit inductive evidence against the direct evidence of human experience. The problem is that experience is what directs our inductive evidential inferences.
So for example, if I see a cat eating green beans, I can reasonably believe that some cats eat green beans. This may fly in the face of the evidence of cat physiology, and someone might construct a compelling argument for the conclusion that cats don't eat green beans based on the evidence of cat physiology, but I could remain firm in my belief that some cats eat green beans in spite of that argument.
Likewise, since I experience God (or know that some people do experience God), I can believe that God exists in spite of inductive evidence that there is pointless evil.
So the argument from evil, to work, will need to be logically sound. Only the final form of the argument is logically sound, so if this form does not work, then there is no defeater for religious experience. And indeed it does not work, since simply inserting the claim that "God has a morally sufficient reason for allowing evil" shows that the set is logically consistent.
Conclusion: Christian Faith
So, some kind of God exists. As we know from experience that this being is supremely good and worthy of worship, it is reasonable to wish to do homage to him. The Christian religion would seem to be the best way for me to do that at any rate, since it is the most plausible religion that I know of.
