What now on the other hand makes people sociable is their incapacity to endure solitude and thus themselves. - Arthur Schopenhauer

All happiness is of a negative rather than positive nature, and for this reason cannot give lasting satisfaction and gratification, but rather only ever a release from a pain or lack, which must be followed either by a new pain or by languor, empty yearning and boredom.

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.

universal compassion is the only guarantee of morality.
