I would have far more fear of being mistaken, and of finding that the Christian religion was true, than of not being mistaken in believing it true.

Let no one say that I have said nothing new... the arrangement of the subject is new. When we play tennis, we both play with the same ball, but one of us places it better.

...for the truth is always older than all the opinions men have held regarding it; and one should be ignoring the nature of truth if we imagined that the truth began at the time it came to be known.

The imagination enlarges little objects so as to fill our souls with a fantastic estimate; and, with rash insolence, it belittles the great to its own measure, as when talking of God.

When we are in love we seem to ourselves quite different from what we were before.

What a chimera then is man. What a novelty! What a monster... what a contradiction, what a prodigy

All man's troubles come from not knowing how to sit still in one room.
