“[I]n other words, we should live with due knowledge of the course of things in the world. For whenever a man in any way loses self-control, or is struck down by a misfortune, grows angry, or loses heart, he shows in this way that he finds things different from what he expected, and consequently that he laboured under a mistake, did not know the world and life, did not know how at every step the will of the individual is crossed and thwarted by the chance of inanimate nature, by contrary aims and intentions, even by the malice inspired in others. Therefore either he has not used his reason to arrive at a general knowledge of this characteristic of life, or he lacks the power of judgement, when he does not again recognize in the particular what he knows in general, and when he is therefore surprised by it and loses his self-control. Thus every keen pleasure is an error, an illusion, since no attained wish can permanently satisfy, and also because every possession and every happiness is only lent by chance for an indefinite time, and can therefore be demanded back in the next hour. Thus both originate from defective knowledge. Therefore the wise man always holds himself aloof from jubilation and sorrow, and no event disturbs his ἀταραξία [ataraxia]."—from_The World as Will and Representation_. Translated from the German by E. F. J. Paye in two volumes: volume I, p. 88”

“Change alone is eternal, perpetual, immortal.”

“Because people have no thoughts to deal in, they deal cards, and try and win one another's money. Idiots!”

“Satisfaction consists in freedom from pain, which is the positive element of life.”

“Almost all of our sorrows spring out of our relations with other people.”

“Great men are like eagles, and build their nest on some lofty solitude.”

“With people of limited ability modesty is merely honesty. But with those who possess great talent it is hypocrisy.”

“To live alone is the fate of all great souls.”

“It is only a man's own fundamental thoughts that have truth and life in them. For it is these that he really and completely understands. To read the thoughts of others is like taking the remains of someone else's meal, like putting on the discarded clothes of a stranger.”

“All truth passes through three stages. First, it is ridiculed. Second, it is violently opposed. Third, it is accepted as being self-evident.”

“The discovery of truth is prevented more effectively, not by the false appearance things present and which mislead into error, not directly by weakness of the reasoning powers, but by preconceived opinion, by prejudice.”
