There must always be some extra-mundane God somewhere, who gives this impetus, who imparts this tangential force. This is always presupposed; and remember, this assumption was made at a time when we had lost all idea of bringing the material and the spiritual into any kind of connection, when we were incapable of conceiving of anything but a perfectly external ‘push’.
