“The only advantage of knowledge is that it can justify suffering.”

“If you suffer and make your loved ones suffer, there is nothing that can justify your desire.”

“The end of suffering does not justify the suffering, and so there is no end to suffering.”

“A means can be justified only by its end. But the end in its turn needs to be justified.”

“Say what you will of fortitude, but show me the man who can patiently endure the laughter of fools when they have obtained an advantage over him. 'Tis only when their nonsense is without foundation that one can suffer it without complaint.”

“And why are you so firmly, so triumphantly, convinced that only the normal and the positive--in other words, only what is conducive to welfare--is for the advantage of man? Is not reason in error as regards advantage? Does not man, perhaps, love something besides well-being? Perhaps he is just as fond of suffering? Perhaps suffering is just as great a benefit to him as well-being? Man is sometimes extraordinarily, passionately, in love with suffering, and that is a fact.”
