“We do not ask for what useful purpose the birds do sing, for song is their pleasure since they were created for singing. Similarly, we ought not to ask why the human mind troubles to fathom the secrets of the heavens... The diversity of the phenomena of Nature is so great and the treasures hidden in the heavens so rich, precisely in order that the human mind shall never be lacking for fresh nourishment.”
― Johannes Kepler

“Never believe that anti-Semites are completely unaware of the absurdity of their replies. They know that their remarks are frivolous, open to challenge. But they are amusing themselves, for it is their adversary who is obliged to use words responsibly, since he believes in words. The anti-Semites have the right to play. They even like to play with discourse for, by giving ridiculous reasons, they discredit the seriousness of their interlocutors. They delight in acting in bad faith, since they seek not to persuade by sound argument but to intimidate and disconcert. If you press them too closely, they will abruptly fall silent, loftily indicating by some phrase that the time for argument is past.”
― Jean-Paul Sartre

“The thing about working with time, instead of against it, he thought, is that it is not wasted. Even pain counts.”
― Ursula K. Le Guin, The Dispossessed: An Ambiguous Utopia

“It isn't changing around from place to place that keeps you lively. It's getting time on your side. Working with it, not against it.”
― Ursula K. Le Guin, The Dispossessed: An Ambiguous Utopia
