This is usually stigmatized as "an appeal to the Passions instead of the Reason;" as if Reason alone could ever influence the Will, and operate as a motive, which it no more can, than the eyes, which show a man his road, can enable him to move from place to place; or than a ship provided with a compass, can sail without a wind.
