A lover is a man who tries to be more amiable than it is possible for him to be.

Contact with the world either breaks or hardens the heart.

Conviction is the conscience of intellect.

He who disguises tyranny, protection, or even benefits under the air and name of friendship reminds me of the guilty priest who poisoned the sacramental bread.

What we love intensely or for a long time we are likely to bring within the citadel, and to assert as part of oneself.

And so I leave this world, where the heart must either break or turn to lead (suicide note)

Knowledge is boundless,--human capacity, limited.
