“A man can be himself only so long as he is alone; and if he does not love solitude, he will not love freedom; for it is only when he is alone that he is really free.”

“Compassion for animals is intimately connected with goodness of character, and it may be confidently asserted that he, who is cruel to living creatures, cannot be a good man. Moreover, this compassion manifestly flows from the same source whence arise the virtues of justice and loving-kindness towards men.”

“I have not yet spoken my last word about women. I believe that if a woman succeeds in withdrawing from the mass, or rather raising herself from above the mass, she grows ceaselessly and more than a man.”

“It is asserted that beasts have no rights; the illusion is harboured that our conduct, so far as they are concerned, has no moral significance, or, as it is put in the language of these codes, that "there are no duties to be fulfilled towards animals." Such a view is one of revolting coarseness, a barbarism of the West, whose source is Judaism. In philosophy, however, it rests on the assumption, despite all evidence to the contrary, of the radical difference between man and beast,—a doctrine which, as is well known, was proclaimed with more trenchant emphasis by Descartes than by any one else: it was indeed the necessary consequence of his mistakes.”

“They tell us that Suicide is the greatest piece of Cowardice… That Suicide is wrong; when it is quite obvious that there is nothing in this world to which every man has a more unassailable title than to his own life and person.”

“True brevity of expression consists in a man only saying what is worth saying, while avoiding all diffuse explanations of things which every one can think out for himself”

Arthur Schopenhauer

Essays, On Authorship and Style
Context: The law of simplicity and naïveté applies to all fine art, for it is compatible with what is most sublime.
True brevity of expression consists in a man only saying what is worth saying, while avoiding all diffuse explanations of things which every one can think out for himself; that is, it consists in his correctly distinguishing between what is necessary and what is superfluous. On the other hand, one should never sacrifice clearness, to say nothing of grammar, for the sake of being brief. To impoverish the expression of a thought, or to obscure or spoil the meaning of a period for the sake of using fewer words shows a lamentable want of judgment.

“Man can do what he wills but he cannot will what he wills.”

“To free a man from error is to give, not to take away. Knowledge that a thing is false is a truth. Error always does harm; sooner or later it will bring mischief to the man who harbors it.”

Context: To free a man from error is to give, not to take away. Knowledge that a thing is false is a truth. Error always does harm; sooner or later it will bring mischief to the man who harbors it. Then give up deceiving people; confess ignorance of what you don't know, and leave everyone to form his own articles of faith for himself. Perhaps they won't turn out so bad, especially as they'll rub one another's corners down, and mutually rectify mistakes. The existence of many views will at any rate lay a foundation of tolerance. Those who possess knowledge and capacity may betake themselves to the study of philosophy, or even in their own persons carry the history of philosophy a step further.

“Truth is no harlot who throws her arms round the neck of him who does not desire her; on the contrary, she is so coy a beauty that even the man who sacrifices everything to her can still not be certain of her favors.”
