Happiness does not consist in self-love. – Joseph Butler
The principle we call self-love never seeks anything external for the sake of the thing, but only as a means of happiness or good: particular affections rest in the external things themselves. – Joseph Butler
Compassion is a call, a demand of nature, to relieve the unhappy as hunger is a natural call for food. – Joseph Butler
The private interest of the individual would not be sufficiently provided for by reasonable and cool self-love alone therefore the appetites and passions are placed within as a guard and further security, without which it would not be taken due care of. – Joseph Butler
