Ocellus Lucanus on the nature of the universe

THEOREM 12.

Everything which is moved, is moved by something.

Demonstration.—Let A be that which is moved, I say that A is moved by something: for it is either moved according or contrary to nature. If, therefore, it is moved according to nature, that which moves is nature; but, if contrary to nature, that which employs violence moves; for every motion contrary to nature is violent.
