Hi INRM,
The question of being 'wired' for faith seems wrong, or at least asks the wrong question.
We evolved according to certain natural (mathematic) principles, so it makes sense that we might ascribe something 'outside the natural' to a principle we realize at some level we can
never know or understand. Suppose for example, that the way we evolved (physically and socially) impacts how we perceive beauty.
Does that mean we are
wired to worship that principle? Have faith in it? Not really. Maybe the proper response is not to have faith in it, but to recognize that it has an aspect of beauty to it, and let it go.
I've given this one some thought today. It would seem that the feeling of something greater than ones self when someone dies -- perhaps that's where people make the leap to there being something after this life.
Here's what I think, and mind you it is an entirely atheist kind of view. Death is a time when we sometimes realize that
we are all one thing. The universe came together for a short time in a way that is incredible, it has now changed again. We are the person who died, and they are us. The core of religious experience is not so much a recognition of 'otherness' but a realization of unity.
It does not take death to understand this 'oneness', things occur all the time that can remind us. There was a violin concert here, can't remember the names but the violinist was world famous, and even the violin had a name (it was a Stradivarius). There is something about that quality of music that evokes that same sense of oneness. The violin had a name because, it was like it was alive.
