There are others, whose prejudices are still more formidable, inasmuch as they are grounded in their moral feelings and religious principles, which had been alarmed and shocked by the impious and pernicious tenets defended by Hume, Priestley, and the French fatalists or necessitarians; some of whom had perverted metaphysical reasonings to the denial of the mysteries and indeed of all the peculiar doctrines of Christianity; and others even to the subversion of all distinction between right and wrong. I would request such men to consider what an eminent and successful defender of the Christian faith has observed, that true metaphysics are nothing else but true divinity, and that in fact the writers, who have given them such just offence, were sophists, who had taken advantage of the general neglect into which the science of logic has unhappily fallen, rather than metaphysicians, a name indeed which those writers were the first to explode as unmeaning. Secondly, I would remind them, that as long as there are men in the world to whom the Gnothi seauton is an instinct and a command from their own nature, so long will there be metaphysicians and metaphysical speculations; that false metaphysics can be effectually counteracted by true metaphysics alone; and that if the reasoning be clear, solid and pertinent, the truth deduced can never be the less valuable on account of the depth from which it may have been drawn. A third class profess themselves friendly to metaphysics, and believe that they are themselves metaphysicians. They have no objection to system or terminology, provided it be the method and the nomenclature to which they have been familiarized in the writings of Locke, Hume, Hartley, Condillac, or perhaps Dr. Reid, and Professor Stewart. To objections from this cause, it is a sufficient answer, that one main object of my attempt was to demonstrate the vagueness or insufficiency of the terms used in the metaphysical schools of France and Great Britain since the revolution, and that the errors which I propose to attack cannot subsist, except as they are concealed behind the mask of a plausible and indefinite nomenclature.
