Man is born free; and everywhere he is in chains. One thinks himself the master of others, and still remains… — Jean Jacques Rousseau

Man is born free; and everywhere he is in chains. One thinks himself the master of others, and still remains a greater slave than they.

In the original (French)

L'homme est né libre, et partout il est dans les fers. Tel se croit le maître des autres, qui ne laisse pas d’être plus esclave qu’eux.
