Supreme happiness consists in self-content.

Anticipation and Hope are born twins.

We are born, so to speak, twice over; born into existence, and born into life; born a human being, and born a man.

Cities are the abyss of the human species.

With children use force; with men reason; such is the natural order of things. The wise man requires no law.

We cannot teach children the danger of telling lies to men without realising, on the man's part, the danger of telling lies to children. A single untruth on the part of the master will destroy the results of his education.

A child who passes through many hands in turn, can never be well brought up. At every change he makes a secret comparison, which continually tends to lessen his respect for those who control him, and with it their authority over him. If once he thinks there are grown-up people with no more sense than children the authority of age is destroyed and his education is ruined.
