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

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.

Virtue, as such, naturally procures considerable advantages to the virtuous.

It is not at all incredible, that a book which has been so long in the possession of mankind should contain many truths as yet undiscovered.

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.

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.

Both our senses and our passions are a supply to the imperfection of our nature; thus they show that we are such sort of creatures as to stand in need of those helps which higher orders of creatures do not.
