Aristotle is described as embracing "naturalism" because:
a. He agrees with Plato that the "Forms" of, for example, "tree" and "human" are naturally good.
b. He believes that democracy is the natural form of human government.
c. He finds beauty and grace in all things natural, and strongly dislikes fake looking art work and dishonest people.
d. He rejects Plato's supernatural level of reality called the "Forms," and focuses instead on scientific observation.
