Is absence of evidence for God evidence of his absence?

From Christopher Copan Scott. (H/T The Poached Egg)

Excerpt:

There is a central question that must be answered in the philosophy of religion: Is absence of evidence, evidence of absence? The answer is that it all depends on what the thingin question is.

Examine these two scenarios:

Suppose in S1 (scenario one) Bob is invited on a challenge to find one golden ant, the only golden ant, and it happens to be somewhere in the 1.7 billion acres known as the Amazon Rainforest. If you were to find this one golden ant in 24 hours you would be rewarded with a large sum of money. Furthermore, suppose Bob the contestant is unsuccessful in this challenge and as a result complains to the organizers of the event saying that because he could not find the golden ant, it therefore does not exist. The problem with his complaint is that in S1, the absence of evidence for this one golden ant, gives little to no justification for you to conclude the non-existence of it.

Let us go on to S2. Here Bob is confronted with a similar challenge, instead he is not trying to find an ant but an elephant, and the environment is not the Amazon Rainforest, but his small office room. In S2, one’s assertion that the lack of evidence of the elephant in his office is evidence of absence of the elephant would be warranted.

This demonstrates that the absence of evidence is evidence of absence for the existence of a particular entity, if and only if it meets the following two conditions:

1)      If the postulated entity were to exist, we should expect to have some evidence of its existence.

2)      We have thoroughly examined the area which we would expect to find the entity.

Now what does this mean when it comes to the existence of God? This means that those who assert that the lack of evidence for the existence of God provides sufficient grounds to assert that this is evidence of absence must take the burden of proving (1) and (2).

This debate has been taken up in what is called the hiddenness of God. So at the least, in order to assert that the absence of evidence is evidence of absence for God one is required to provide justification for this claim.

For a longer treatment of the question of the hiddenness of God, please see a paper by philosopher Michael Murray, which I discuss in this post. This is an important philosophical problem that rarely comes up in the formal academic debates that we all love to watch with William Lane Craig. On a related note, it’s worth taking a look at the concept of burden of proof as it relates to the problems of evil and suffering. There are lots of links to lectures and essays in that post.
