Thoughtless people contradict as readily the statement of perceptions as of opinions, or rather much more readily; for they do not distinguish between perception and notion. They fancy that I choose to see this or that thing. But perception is not whimsical, but fatal. If I see a trait, my children will see it after me, and in course of time all mankind, — although it may chance that no one has seen it before me. For my perception of it is as much a fact as the sun.
