Compassion is the basis of morality. - Arthur Schopenhauer

"We can come to look upon the deaths of our enemies with as much regret as we feel for those of our friends, namely, when we miss their existence as witnesses to our success."

"A man can be himself only so long as he is alone, and if he does not love solitude, he will not love freedom, for it is only when he is alone that he is really free."

"Happiness consists in frequent repetition of pleasure"

"Almost all of our sorrows spring out of our relations with other people. There is no more mistaken path to happiness than worldliness."

"Qualsiasi uomo notevole, chiunque cioè non appartenga a quei 5/6 dell'umanità dotati tanto miseramente dalla natura, rimarrà dopo i quarant'anni difficilmente esente da una certa traccia di misantropia."
