I have suffered too much in this world not to hope for another.

Teach by doing whenever you can, and only fall back upon words when doing it is out of the question.

Everything is in constant flux on this earth. Nothing keeps the same unchanging shape, and our affections, being attached to things outside us, necessarily change and pass away as they do. Always out ahead of us or lagging behind, they recall a past which is gone or anticipate a future which may never come into being; there is nothing solid there for the heart to attach itself to. Thus our earthly joys are almost without exception the creatures of a moment.

The problem is to find a form of association which will defend and protect with the whole common force the person and goods of each associate, and in which each, while uniting himself with all, may still obey himself alone, and remain as free as before.

Heroes are not known by the loftiness of their carriage; the greatest braggarts are generally the merest cowards.

Every free action has two causes that come together to produce it. One is moral, the will that determines the act; the other is physical, the power that executes the will to act.

Women speak at an earlier age, more easily, and more agreeably than men; they are accused also of speaking more; this is as it should be, and I willingly change the reproach into a eulogy.
