Old ideas are continually being slain by new facts. There is nothing stable in the conclusions of the mind, and it is impossible that there ever should be unless we hold that the universe is made to the measure of the human mind, an assumption for which nothing in the past gives any warrant.

Theories that go counter to the facts of human nature are foredoomed.

None so good that he has no faults, None so wicked that he is worth naught.
