Here is an interesting article about Apatheism -

I have always contended that reason contradicts the existence of God.
However, I have also noted that most people I knew of were pretty reasonable, pragmatic people that, for some reason, believed in God. Thus, I made every attempt to understand the reasoning behind their beliefs.
This was where I hit a stone wall. All of them were absolutely sure about their belief in God; yet, somehow, they found it difficult to expound upon their beliefs.
This frustrated me.
Don't get me wrong, I was not frustrated by their beliefs; rather, I was flummoxed by my own understanding, or lack thereof, of them.
I found "apatheism" interesting because it helped pigeonhole a lot of people around me (at least better than any other previous denomination that I knew of) and because it helped in bettering my understanding of their beliefs
Although I didn't agree with some of the author's claims, I found the article to be, on the whole, an interesting read.
P.S. There is also a good article about introversion in the same site - actually that's how I got to that blog.
