Thus HELVETIUS, in his work on MAN, says expressly: "There is no man of understanding who does not acknowledge _an active power in Nature; there is, therefore, no Atheist_.

He is not an Atheist who says that _motion is God_; because, in fact, motion is incomprehensible, as we have no clear idea of it, since it does not manifest itself but by its effects, and because by it all things are performed in the universe.

He is not an Atheist who says, on the contrary, that _motion is not God_, because motion is not a being, but a mode of being.

They are not Atheists who maintain that motion is essential to matter, and regard it as the invisible and moving force that spreads itself through all its parts," "as the universal soul of matter, and the divinity that alone penetrates its substance.

Are the philosophers of this last opinion Atheists?
No; they equally acknowledge an unknown force in the universe.
