(Via Steve)

Well, I grew up Roman Catholic and was a believing Christian until 17 or so. More and more I came to see that things which I’d explained religiously, such as the existence of life, had perfectly naturalistic explanations. I remember that the last thing that held me to Catholicism was consciousness, which I assumed could only be explained by a soul. Gradually, I came to see that that view was grasping at straws, and I gave up all religious belief.
