I slid gently into atheism and my total failure to believe in souls was the way I realized I was in fact an atheist.

I was reading something that was discussing something about souls and I thought, pfft, there's no such thing as souls.

I think we're made out of meat. The thing that makes me me is a series of electrical impulses in (mostly?) my brain meat. That's why I find sports that involve repeated head trauma (football, boxing, etc) viscerally upsetting: by getting concussed a bunch of times you are, in my view, literally risking obliteration of the self.
