" Thanks be then to nature for this unsociableness, for this envious jealousy and vanity, for this insatiable desire for possession and for power..

Man wishes concord; but nature knows better what is good for his species; and she wills discord, in order that man may be impelled to a new exertion of his powers, and to the further development of his natural capacities. "

― Will Durant , The Story of Philosophy: The Lives and Opinions of the World's Greatest Philosophers
