“Live according to Nature, runs the maxim of the West; but according to what nature, the nature of the body or the nature which exceeds the body? This first we ought to determine.”

“According to one mode… nature is thus denominated, viz. the first subject matter to every thing which contains in itself the principle of motion and mutation. But after another mode it is denominated form, which subsists according to definition: for as art is called that which subsists according to art, and that which is artificial; so likewise nature is both called that which is according to nature, and that which is natural. …that which is composed from these is not nature, but consists from nature; as, for instance, man. And this is nature in a greater degree than matter: for every thing is then said to be, when it is form in energy… entelecheia, rather than when it is incapacity.”

“While all bodies are composed of the four elements, that is, of heat, moisture, the earthy, and air, yet there are mixtures according to natural temperament which make up the natures of all the different animals of the world, each after its kind.”

“It were Happy if we studied Nature more in natural Things; and acted according to Nature; whose rules are few, plain and most reasonable.”

“The end may be defined as life in accordance with nature or, in other words, in accordance with our own human nature as well as that of the universe.”

“Unless man have a natural bent in accordance with nature's, he has no chance of understanding nature at all.”

“Living virtuously is equal to living in accordance with one's experience of the actual course of nature”

“If a plant cannot live according to its nature, it dies; and so a man.”

“To a rational being it is the same thing to act according to nature and according to reason.”

“Tell them that we are all one living body that cannot be separated from nature.”
