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.

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.

Thus there is no doubt the eye was intended for us to see with.

Every thing is what it is, and not another thing.

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.

Compassion is a call, a demand of nature, to relieve the unhappy as hunger is a natural call for food

The only distinct meaning of the word "natural" is stated, fixed, or settled; since what is natural as much requires and presupposes an intelligent agent to render it so, i.e. to effect it continually or at stated times, as what is supernatural or miraculous does to effect it for once.
