I've been enthusing about
this beautiful post about atheism by
approximator for the last several days, and saying that I ought to post a link to it. Well, now I have :)
"I may not believe in a personal god, but I do believe in love. I think that love is a common emotional response that provides an evolutionary advantage. Love is a gift from our ancestors, they selected each other for mates based on the ability to express love and thus selected love as an important attribute for all of us."
