Freedom, morality, and the human dignity of the individual consists precisely in this; that he does good not because he is forced to do so, but because he freely conceives it, wants it, and loves it.

Liberty means that a man is recognized as free and treated as free by those who surround him.

The individual who dares commit a crime is guilty in a two-fold sense; first, he is guilty against human conscience, and, above all, he is guilty against the State in arrogating to himself one of its most precious privileges.

There is only one power and one dictatorship whose organisation is salutary and feasible: it is that collective, invisible dictatorship of those who are allied in the name of our principle.

We must spread our principles, not with words but with deeds, for this is the most popular, the most potent, and the most irresistible form of propaganda.

The liberty of man consists solely in this, that he obeys the laws of nature because he has himself recognized them as such, and not because they have been imposed upon him externally by any foreign will whatsoever, human or divine, collective or individual.

The organization of society is always and everywhere the unique cause of the crimes committed by individuals.
