The Nature of the Psyche: Its Human Expression

"You are each born with the conscious knowledge of what has come before. Your brain is far from an empty slate, waiting for the first imprint of experience; it is already equipped with complete "equations", telling you who you are and where you have come from. Nor do you wipe that slate clean, symbolically speaking, before you write your life upon it. Instead, you draw upon what has gone before: the experiences of your ancestors, back through time immemorial."
