Skeptical theism states that if we cannot tell whether any of the evils in our world are gratuitous, then we cannot appeal to the existence of gratuitous evil to conclude that God does not exist. However, I can't help but think that we can. The rules of probability tell us that that individual probabilities can be quite low, but their disjunction can be very high. For instance, there may be only a small chance that you will be involved in an automobile accident on a given day, but if you drive every day, the chances are pretty good that you will be in one on some day in your lifetime. Similarly, even if the chance that a given instance of a trillion cases of suffering is gratuitous is quite low, the chance that one of that trillion is gratuitous can be can be very high, and it only takes one instance of gratuitous evil to rule out the existence of God. Coming from someone who is not a philosophy major, am I right in my criticism of skeptical theism or is it too naive?
