We love without heeding reason, and cease to love in the same manner.

I have loved women even to madness, but I have always loved liberty better.

I know that I have lived because I have felt, and, feeling giving me the knowledge of my existence.

I have felt in my very blood, ever since I was born, a most unconquerable hatred towards the whole tribe of fools, and it arises from the fact that I feel myself a blockhead whenever I am in their company.

It is only necessary to have courage, for strength without self-confidence is useless.

If I had married a woman intelligent enough to guide me, to rule me without my feeling that I was ruled, I should have taken good care of my money, I should have had children, and I should not be, as now I am, alone in the world and possessing nothing.

The philosopher is a person who refuses no pleasures which do not produce greater sorrows, and who knows how to create new ones.
