What amazes me most is to see that everyone is not amazed at his own weakness.

It is of dangerous consequence to represent to man how near he is to the level of beasts, without showing him at the same time his greatness. It is likewise dangerous to let him see his greatness without his meanness. It is more dangerous yet to leave him ignorant of either; but very beneficial that he should be made sensible of both.

There was once in man a true happiness of which there now remain to him only the mark and empty trace, which he in vain tries to fill from all his surroundings, seeking from things absent the help he does not obtain in things present.

Nothing is so insufferable to man as to be completely at rest, without passions, without business, without diversion, without study. He then feels his nothingness, his forlornness, his insufficiency, his dependence, his weakness, his emptiness. There will immediately arise from the depth of his heart weariness, gloom, sadness, fretfulness, vexation, despair.

All men naturally hate each other. We have used concupiscence as best we can to make it serve the common good, but this is mere sham and a false image of charity, for essentially it is just hate.

All the dignity of man consists in thought. Thought is therefore by its nature a wonderful and incomparable thing. It must have strange defects to be contemptible. But it has such, so that nothing is more ridiculous. How great it is in its nature! How vile it is in its defects! But what is this thought? How foolish it is!

The entire ocean is affected by a single pebble.
