Does Belief Always Require Evidence? (Pt. II)

I closed yesterday's post with the assertion that just as it would be foolish to expect Ellie Arroway or Kirsten Powers to discount their experiences because they can't empirically prove that they had them, so, too, it's foolish of skeptics to think that the only warrant for belief in God is the ability to provide objective, physical evidence that the belief is true.

Yet the alleged lack of evidence for theism has long been one of the most popular reasons adduced for the refusal to accept it. As the 20th century philosopher Bertrand Russell famously said when asked what he would tell God were he to stand before Him after his death and be asked why he never believed, Russell declared that he would simply tell God that "there wasn't enough evidence."

The 19th century writer W.K. Clifford insisted that “It is wrong always, everywhere, and for anyone to believe anything upon insufficient evidence,” and the 20th century philosopher Antony Flew, before his conversion to theism, wrote that,

If it is to be established that there is a God then we have to have good grounds for believing that this is indeed so. Until or unless some such grounds are produced we have literally no reason at all for believing; and in that situation the only reasonable posture must be that of either atheism or agnosticism.

Theists contend that notwithstanding the skeptic's claim that there's not enough evidence to support a belief in God, the evidence is substantial and indeed, overwhelming.

It's not to the purpose of this post to recount that evidence here, but doubters are urged to read philosopher of science Stephen Meyer's latest book Return of the God Hypothesis to get an idea of why many theists believe the evidence is indeed dispositive for anyone who's not already dead set against it.

What is to the purpose in the present post, though, is to show that the demand for evidence before belief is warranted is very selective. What I mean is that skeptics often believe a lot of things for which they not only don't have evidence but for which evidence may not even be theoretically possible.

Here are some examples:

1. Memory beliefs (I believe I had a dream last night.)
2. Belief that we have (or don't have) free-will.
3. Belief that logical axioms are true and self-evident (If A then not ~A.)
4. Belief that there are an infinity of other universes.
5. Belief that every event has a cause.
6. Belief that nothing can cause itself.
7. Belief that life arose in some "warm little pond." (Darwin)
8. Belief that life is the product of material causes only.
9. Belief that justice is right and cruelty is wrong (What evidence justifies this or any moral belief?)
10. Belief that there is a past, present, or future.
11. Belief in the principle of cause and effect.
12. Belief that "the cosmos is all there is, ever was, or ever will be" (Carl Sagan).
13. Belief that evidence is necessary to warrant belief (Is there any evidence to support this belief?)

If skeptics hold these beliefs even though there's no empirical evidence for any of them, why is it thought to be a legitimate criticism of theists that they believe in the existence of God, especially since, as I mentioned above, there's lots of evidence that God exists?
