“No philosophy that he had ever heard or read gave any reasonable purpose for man's existence, nor any rational clue to his proper conduct. Basking in the sunshine might be as good a thing to do with one's life as any other — but it was not for him and he knew it, even if he could not define how he knew it.”

— Robert A. Heinlein, book Methuselah's Children

“Duran knew how to fight. He knew what to do. If he looked at the corner the only thing I ever had to do was pretend to jab, once he was using his jab I knew he’d have no trouble. Even more important he knew how to think. When you talk about great fighters, always remember there was a guy named Roberto Duran. He was never given the opportunity to really display his wares because at his peak, he was overshadowed by Muhammad Ali.”

“Though not as bad as most, he was going through that stage where he knew everything worth knowing and nothing his elders said—particularly if it bore any vaguely education hue—was worth hearing. He could not help that. It went with the age.
And I was my age and could not help saying things I knew would do no good.”

“He who does not know what the world is, does not know where he is. And he who does not know for what purpose the world exists, does not know who he is, nor what the world is. But he who has failed in any one of these things could not even say for what purpose he exists himself. What then dost thou think of him who [avoids or] seeks the praise of those who applaud, of men who know not either where they are or who they are?”

Marcus Aurelius book Meditations

He that knows not what the world is, knows not where he is himself. He that knows not for what he was made, knows not what he is nor what the world is.
VIII, 52
