“It would be a great mistake to suppose that it is sufficient not to become personal yourself. For by showing a man quite quietly that he is wrong, and that what he says and thinks is incorrect — a process which occurs in every dialectical victory — you embitter him more than if you used some rude or insulting expression. Why is this? Because, as Hobbes observes, all mental pleasure consists in being able to compare oneself with others to one’s own advantage. — Nothing is of greater moment to a man than the gratification of his vanity, and no wound is more painful than that which is inflicted on it. Hence such phrases as “Death before dishonour,” and so on.”

“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.”
