"Mit der Dummheit kämpfen Götter selbst vergebens."
I admired it much more than I actually enjoyed it. Asimov's ideas are brilliant but his characters are somewhat bloodless and cardboard. Even when he tries to work against this it comes out all embarrassing. The third section on the moon is a pale imitation to Heinlein's 'Moon is a Harsh Mistress'. Given the timing on the publication that can't have been an accident.
