The object of self-love is expressed in the term self; and every appetite of sense, and every particular affection of the heart, are equally interested or disinterested, because the objects of them all are equally self or somewhat else.
Joseph ButlerEvery one of our passions and affections hath its natural stint and bound, which may easily be exceeded; whereas our enjoyments can possibly be but in a determinate measure and degree.
Joseph ButlerSelf-love then does not constitute THIS or THAT to be our interest or good; but, our interest or good being constituted by nature and supposed, self-love only puts us upon obtaining and securing it.
Joseph ButlerHappiness or satisfaction consists only in the enjoyment of those objects which are by nature suited to our several particular appetites, passions, and affections.
