Whoever is not a misanthrope at forty can never have loved mankind.
There some trifles well habited, as there are some fools well clothed.
At the sight of what goes on in the world, the most misanthropic of men must end by being amused, and Heraclitus must die laughing.
Pleasure may come from illusion, but happiness can come only of reality.
Public opinion reigns in society because stupidity reigns amongst the stupid.
It is said of a lonely man that he does not appreciate the life of society. This is like saying he hates hiking because he dislikes walking in thick forest on a dark night.
