Man is effect and cause.

He is fed, but he feeds in turn.

When you call God a Creator, you dwarf Him.
He did not create, as you think He did, plants or animals or stars.
Could He proceed by a variety of means?
Must He not act by unity of composition?
Moreover, He gave forth principles to be developed, according to His universal law, at the will of the surroundings in which they were placed.

Hence a single substance and motion, a single plant, a single animal, but correlations everywhere.

In fact, all affinities are linked together by contiguous similitudes; the life of the worlds is drawn toward the centres by famished aspiration, as you are drawn by hunger to seek food.
"To give you an example of affinities linked to similitudes (a secondary law on which the creations of your thought are based), music, that celestial art, is the working out of this principle; for is it not a complement of sounds harmonized by number?
Is not sound a modification of air, compressed, dilated, echoed?
You know the composition of air,--oxygen, nitrogen, and carbon.
