Primary substance = ether

Every particle of matter is composed of a primary substance-- the ether--filling all space. The atom of any elementary body is differentiated from the rest of this tenuous substance merely by a spinning motion like a whirl in a calm lake. By being set in movement ether becomes palpable matter; the movement arrested, the primary substance reverts to its normal state and becomes imperceptible....To create and annihilate material substance, to cause at will its birth and death, would be man's most consequential deed--his greatest achievement, which would place him beside his creator, make him fulfill his ultimate destiny.
