The heart has its order, the mind has its own, which uses principles and demonstrations. The heart has a different one. We do not prove that we ought to be loved by setting out in order the causes of love; that would be absurd.

We desire truth, and find within ourselves only uncertainty. We seek happiness, and find only misery and death. We cannot but desire truth and happiness, and are incapable of certainty or happiness.

It is not certain that everything is uncertain.

Man lives between the infinitely large and the infinitely small.

All mankind's troubles are caused by one single thing, which is their inability to sit quietly.

Too much and too little wine. Give him none, he cannot find truth; give him too much, the same.

I know whom I have believed.
