Christopher Hitchens solves a mystery for me and gives me some German to pass along to my son. Freud said something like Nietzsche new himself best or had the best grasp of psychology in the previous generation. Nietzsche died shortly after having jumped in a river yelling some wild statement; so this didn't make sense to me. Hitchens points out that he had tertiary syphilis (which doesn't preclude you being sane earlier). Having addressed this mystery, there comes up the idea that Nietzsche would seem to have addressed issues of narcissism whereas Freud was more into dynamic understanding, anyway a lessor problem.
