But I'm thinking that to become who you are you need to know history, you need to know your basic drives without a whole lot of moralizing about good and bad you need knowledge of your evolutionary history and the challenges all your generations faced and survived long enough to share DNA to understand some of your basic drives. I can go on and on about this. Very few people have plummeted the depths of their psyche like Nietzsche, and perhaps that is what led to him going mad at such a young age.
Jung's was surprised that the Buddha was able to make so much of his unconscious conscious and not go insane.
