"None of the gods philosophizes," Plato has Diotima say in the Symposium: "nor do fools; for that is what is so bad about ignorance — that you think you know enough." "Who, then, O Diotima, I asked, are the philosophers, since they are neither those who know nor those who don't know?" Then she answered me: "It's so obvious, Socrates, that a child could understand: the philosophers are the ones in between." This "in-between" is the realm of the truly human. It is truly human, on the one hand, not to understand (as God), and on the other hand, not to become hardened; not to include oneself in the supposedly completely illuminated world of day-today life.
