Francis Collins has some interesting observations on agnosticism perhaps being the ultimate cop out*. He was agnostic, then atheist, then believer. Interesting journey.
He's quoted in this excellent book too. Written by another scientist**.
I think it's often a simple case of life's baggage determine how we view the idea of faith and God. And as an exJW, I fully recognise that the Governing Body have ladened us with more than our personal allowance.
*Quote: "In response, Collins clarified his position on agnosticism so as not to include "earnest agnostics who have considered the evidence and still don't find an answer. I was reacting to the agnosticism I see in the scientific community, which has not been arrived at by a careful examination of the evidence."
**Not sure if those of a scientific background on this forum would consider him a real scientist as I'm not clear on the predicating conditions with which one science is considered more or less legitimate than another.
