Quote from : The Bonobo and the Atheist: In Search of Humanism Among the Primates Book

Along with people in other creative professions, such as artists and musicians, many scientists experience this transcendence. I do so every day. For one, it's impossible to look an ape in the eye and not see oneself. There are other animals with frontally oriented eyes, but none that give you the shock of recognitions of the ape's. Looking back at you is not so much an animal but a personality as solid and willful as yourself.
