The deplorable mania of doubt exhausts me. I doubt about everything, even my doubts.

I am a man-pen. I feel through the pen, because of the pen.

Since you are now studying geometry and trigonometry, I will give you a problem. A ship sails the ocean. It left Boston with a cargo of wool. It grosses 200 tons. It is bound for Le Havre. The mainmast is broken, the cabin boy is on deck, there are 12 passengers aboard, the wind is blowing East-North-East, the clock points to a quarter past three in the afternoon. It is the month of May. How old is the captain?

The idea of bringing someone into the world fills me with horror. I would curse myself if I were a father. A son of mine! Oh no, no, no! May my entire flesh perish and may I transmit to no one the aggravations and the disgrace of existence.

The hearts of women are like those little pieces of furniture with secret hiding - places, full of drawers fitted into each other; you go a lot of trouble, break your nails, and in the bottom find some withered flower, a few grains of dust - or emptiness!

The rage for wanting to conclude is one of the most deadly and most fruitless manias to befall humanity. Each religion and each philosophy has pretended to have God to itself, to measure the infinite, and to know the recipe for happiness. What arrogance and what nonsense! I see, to the contrary, that the greatest geniuses and the greatest works have never concluded.
