One must be born to any superior world -- to make it plainer, one must be bred for it. One has a right to philosophy (taking the word in its greatest sense) only by virtue of one's breeding. One's ancestors, one's "blood" decides this, too. Many generations must have worked on the origin of a philosopher; each one of his virtues must have been separately earned, cared for, passed on, made flesh and blood.
