The most common form of despair is not being who you are.

There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.

The greatest hazard of all, losing one’s self, can occur very quietly in the world, as if it were nothing at all. No other loss can occur so quietly; any other loss - an arm, a leg, five dollars, a wife, etc. - is sure to be noticed.

The tyrant dies and his rule is over, the martyr dies and his rule begins.

To venture causes anxiety, but not to venture is to lose one's self.... And to venture in the highest is precisely to be conscious of one's self.

It is the thought, not the incidentals of expression, that essentially makes an exposition unpopular. A systematic ribbon and button maker can become unpopular but essentially is not at all, inasmuch as he does not mean much by the very odd things he says (alas, and this is a popular art!). Socrates, on the other hand, was the most unpopular in Greece because he said the same thing as the simplest person but meant infinitely much by it. To be able to stick to one thing, to stick to it with ethical passion and undauntedness of spirit, to see the intrinsic duplexity of this one thought with the same impartiality, and at one and the same time to see the most profound earnestness and the greatest jest, the deepest tragedy and highest comedy―this is unpopular in any age for anyone who has not realized that immediacy is over. But neither can what is essentially unpopular be learned by rote. More on that later.
