In the true state of nature egoism did not exist - Jean-Jacques Rousseau

To this motive which encourages me is added another which made up my mind: after I have upheld, according to my natural intelligence, the side of truth, no matter what success I have, there is a prize which I cannot fail to win. I will find it in the depths of my heart.

Le plus fort n'est jamais assez fort pour être toujours le maître, s'il ne transforme sa force en droit et l'obéissance en devoir.

I am not worried about pleasing clever minds or fashionable people. In every period there will be men fated to be governed by the opinions of their century, their country, and their society. For that very reason, a freethinker or philosopher today would have been nothing but a fanatic at the time of the League.* One must not write for such readers, if one wishes to live beyond one’s own age.
