It is the set of the sails, not the direction of the wind that determines which way we will go.
The root issue in the discussion of the nature of man, is whether or not man is basically good or basically bad. Everyone believes that man is basically good, and that he can save himself. I’m not sure why they think he needs saving, if he’s basically good, but every world view has some salvation mechanism like enlightenment, social reform, etc. But basically, they are all part of the Frankenstein crowd.
