Pleasure-Displeasure

Can you learn to live ? Yes, if you are not happy. There is no virtue in felicity. (Colette)

Not joy but joylessness is the mother of debauchery. (Nietzsche)

The greatest happiness you can have is knowing that you do not necessarily require happiness. (William Saroyan)

Nature, with her customary beneficence, has ordained that man shall not learn how to live until the reasons for living are stolen from him, that he shall find no enjoyment until he has become incapable of vivid pleasure. (Giacomo Leopardi)

Life is a progress from want to want, not from enjoyment to enjoyment. (Samuel Johnson)

The greatest happiness of the greatest number is the foundation of morals and legislation. (Jeremy Bentham)
