The Intellectual Arbitrariness Objection to Religious Exclusivism: version 1

Here is my presentation of the objection:

The objection here claims that we have an epistemic duty to treat like cases alike: if the evidence I have for p is the same (or similar) to the evidence that you have for ~p, then we should suspend belief with respect to p and ~p.

Response 1: The evidence will, in many or most cases, not be relevantly similarly. The phenomenology (the way the evidence is experienced by the subject) will be different, and thus the internal evidence will be different. Different rankings of evidence will be likely resulting in different overall assessment of the evidence. 

Reply: But those who deny (1) and (2) may have the same phenomenology and whatnot so that there really is relevant similarity—all the way down to how the evidence feels and is assessed. Think of two different detectives with the exact same evidence, same experience on the job, same level of intelligence, etc. and yet they each arrive at a different conclusion. Is that possible? If so, then it seems like it is possible when it comes to religious matters. In the detective case, they should suspend belief (according to the objection we are considering). Same for the religious case.

Response 2: Well, Plantinga (and I agree) do not think that the evidence for the existence of God and the evidence of for the denial of God's existence are on a par. Those who seriously, thoughtfully, patiently, virtuously, humbly, etc consider all the evidence, rationally should give more weight to God's existence than to the denial of God's existence. 

Reply: But suppose we are wrong. Suppose the evidence really is equal. What happens? 

Response 3: Nothing at all may follow. The objection is assuming something like the following principle: 

Epistemic Similarity: If S1 and S2 have all the same evidence, attention, time, etc. with respect to p, and S1 and S2 disagree about p, then S1 and S2 should suspend belief about p.

But lots of people disagree with Epistemic Similarity.  So we should suspend belief about Epistemic Similarity because that's what the principle tells us to do in such cases. The principle commands us to suspend belief in cases of the relevant kind of disagreement. Since there is such disagreement when it comes to the principle itself, we should suspend belief about the principle.  So we can't use it.
