“I might have been your happiness, and became your misfortune.”
Rome, 5 December
Without Dogma (1891)
Context: I might have been your happiness, and became your misfortune. I am the cause of your death, for if I had been a different man, if I had not been wanting in all principles, all foundations of life, there would not have come upon you the shocks that killed you.

“It is a kind of happiness to know how unhappy we must be.”
C’est une espèce de bonheur, de connaître jusqu’à quel point on doit être malheureux.
Maxim 8 of the Maximes supprimées.
