Every man hath a general desire of his own happiness and likewise a variety of particular affections, passions, and appetites to particular external objects. – Joseph Butler
Happiness or satisfaction consists only in the enjoyment of those objects which are by nature suited to our several particular appetites, passions, and affections. – Joseph Butler
