Ptolemy was wrong. But he was wrong with a large pile of actual measurements of celestial bodies, and a falsifiable theory. That made him wrong in the positive sense of wrong in the phrase "not even wrong", where wrong is just the first step of the ladder. I wish I could say the same about Freud, but that ladder is distressingly horizontal.
