I do believe that man is a rope between animal and superman. But the superman I'm thinking of isn't Nietzsche's. The real superhuman, man or woman, is the person who's rid himself of all prejudices, neuroses, and psychoses, who realizes his full potential as a human being, who acts naturally on the basis of gentleness, compassion, and love, who thinks for himself and refuses to follow the herd. That's the genuine dyed-in-the-wool superman.
