The great man fights the elements in his time that hinder his own greatness, in other words his own freedom and sincerity.

Beggars should be entirely abolished! Truly, it is annoying to give to them and annoying not to give to them.

What is it that you love in others?--My hopes.

Profundity of thought belongs to youth, clarity of thought to old age.

One receives as reward for much ennui, despondency, boredom -such as a solitude without friends, books, duties, passions must bring with it -those quarter-hours of profoundest contemplation within oneself and nature. He who completely entrenches himself against boredom also entrenches himself against himself: he will never get to drink the strongest refreshing draught from his own innermost fountain.

Logic, too, also rests on assumptions that do not correspond to anything in the real world, e.g., on the assumption that there areequal things, that the same thing is identical at different points in time: but this science arose as a result of the opposite belief (that such things actually exist in the real world). And it is the same with mathematics, which would certainly never have arisen if it had been understood from the beginning that there is no such thing in nature as a perfectly straight line, a true circle, and absolute measure.
