2 - Part II. Consciousness
An Aristotelian account
Of the things that exist, some exist by nature, some from other causes. By nature the animals and their parts exist, and the plants and the simple bodies (earth, fire air, water)—for we say that these and the like exist by nature…. For each of them has within itself a principle of motion and of stationariness (in respect of place, or of growth and decrease, or by way of alteration).Aristotle (Physics 192b:9–16)
Nature is a principle of motion and change. … We must therefore see that we understand what motion is; for if it were unknown, nature too would be unknown.Aristotle (Physics 200b:12–14)
