I haven't bookmarked any quotes at the moment.
Destiny is an absolutely definite and inexorable ruler. Physical ability and moral determination count for nothing. It is impossible to perform the simplest act when the gods say no. I have no idea how they bring pressure to bear on such occasions; I only know that it is irresistible.
But wait... my book has more:
Progress is impossible without change, and those who cannot change their minds cannot change anything.
Women wish to be loved not because they are pretty, or good, or well bred, or graceful, or intelligent, but because they are themselves.
Bad people are less a problem than indifferent people.
Look at things... as they can be.
