Every 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.

Every man hath a general desire of his own happiness; and likewise a variety of particular affections, passions, and appetites to particular external objects.

Happiness or satisfaction consists only in the enjoyment of those objects which are by nature suited to our several particular appetites, passions, and affections.

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.

I measure the progress of a community by the degree of progress which women have achieved.

Man may act according to that principle or inclination which for the present happens to be strongest, and yet act in a way disproportionate to, and violate his real proper nature.
