Stupidity can win for a moment, but it can never really succeed because the nature of humans is to seek freedom. Rulers can delay that freedom, but they cannot stop it.
When I come upon anything-in Logic or in any other hard subject-that entirely puzzles me, I find it a capital plan to talk it over, aloud, even when I am all alone. One can explain things so clearly to one's self! And then, you know, one is so patient with one's self: one never gets irritated at one's own stupidity!
