Instinct teaches us to look for happiness outside ourselves.

Curiosity is only vanity. We usually only want to know something so that we can talk about it.

When we see an effect happen always in the same manner, we infer that it takes place by a natural necessity; as, for instance, that the sun will rise to morrow; but nature often deceives us, and will not submit to its own rules.

Human life is thus only an endless illusion. Men deceive and flatter each other. No one speaks of us in our presence as he does when we are gone. Society is based on mutual hypocrisy.

Our nature consists in motion; complete rest is death.

We must keep our thought secret, and judge everything by it, while talking like the people.

The heart has its reasons which reason knows nothing of... We know the truth not only by the reason, but by the heart." - Blaise Pascal
