There is more heroism in self-denial than in deeds of arms.
To be always fortunate, and to pass through life with a soul that has never known sorrow, is to be ignorant of one half of nature.
True wisdom consists in not departing from nature and in molding our conduct according to her laws and model.
He will live ill who does not know how to die well.
What is true belongs to me!
Nothing will ever please me, no matter how excellent or beneficial, if I must retain the knowledge of it to myself. . . . . . No good thing is pleasant to possess, without friends to share it.
