" The more I think about myself, the more I'm persuaded that, as a person, I really don't exist. That is one of the reasons why I can't believe in any orthodox religion: I cannot believe in my own soul. No, I am a chemical compound, conditioned by environment and education. My "character" is simply a repertoire of acquired tricks, my conversation a repertoire of adaptations and echoes, my "feelings" are dictated by purely physical, external stimuli. "
