1. We notice a prominent and important mistake common to metaphysicians, especially of the German school, in their Treatises on the Will. Liberty of Will with them is Liberty as distinguished from Moral Servitude, and not as distinguished from Necessity. Hence, in all their works, very little light is thrown upon the great idea of Liberty, which lies at the foundation of moral obligation, to wit: Liberty as distinguished from Necessity. “A free Will,” says Kant, “and a Will subjected to the Moral Law, are one and identical.” A more capital error in philosophy is not often met with than this.
