From “Thoughts.” Translation of C. Keegan Paul.

ALL things here are true in part, and false in part. Essential truth is not thus, it is altogether pure and true. This mixture dishonors and annihilates it. Nothing is purely true, and therefore nothing is true, understanding by that pure truth. You will say it is true that homicide is an evil; yes, for we know well what is evil and false. But what can be named as good? Chastity? I say no, for then the world would come to an end. Marriage? No, a celibate life is better. Not to kill? No, for lawlessness would be horrible, and the wicked would kill all the good. To kill then? No, for that destroys nature. Goodness and truth are therefore only partial, and mixed with what is evil and false.

  Were we to dream the same thing every night, this would affect us as much as the objects we see every day, and were an artisan sure to dream every night, for twelve hours at a stretch, that he was a king, I think he would be almost as happy as a king who should dream every night for twelve hours at a stretch that he was an artisan.

  Should we dream every night that we were pursued by enemies, and harassed by these painful phantoms, or that we were passing all our days in various occupations, as in traveling, we should suffer almost as much as if the dream were real, and should fear to sleep, as now we fear to wake when we expect in truth to enter on such misfortunes. And, in fact, it would bring about nearly the same troubles as the reality.

  But since dreams are all different, and each single dream is diversified, what we see in them affects us much less than what we see when awake, because that is continuous, not indeed so continuous and level as never to change, but the change is less abrupt, except occasionally, as when we travel, and then we say, “I think I am dreaming,” for life is but a little less inconstant dream.
