Mr Godwin's five propositions respecting political truth, on which his whole work hinges, not established--Reasons we have for supposing, from the distress occasioned by the principle of population, that the vices and moral weakness of man can never be wholly eradicated--Perfectibility, in the sense in which Mr Godwin uses the term, not applicable to man--Nature of the real perfectibility of man illustrated. If the reasonings of the preceding chapter are just, the corollaries respecting political truth, which Mr Godwin draws from the proposition, that the voluntary actions of men originate in their opinions, will not appear to be clearly established. These corollaries are, "Sound reasoning and truth, when adequately communicated, must always be victorious over error: Sound reasoning and truth are capable of being so communicated: Truth is omnipotent: The vices and moral weakness of man are not invincible: Man is perfectible, or in other words, susceptible of perpetual improvement." The first three propositions may be considered a complete syllogism. If by adequately communicated, be meant such a conviction as to produce an adequate effect upon the conduct, the major may be allowed and the minor denied. The consequent, or the omnipotence of truth, of course falls to the ground. If by 'adequately communicated' be meant merely the conviction of the rational faculty, the major must be denied, the minor will be only true in cases capable of demonstration, and the consequent equally falls. The fourth proposition Mr Godwin calls the preceding proposition, with a slight variation in the statement. If so, it must accompany the preceding proposition in its fall. But it may be worth while to inquire, with reference to the principal argument of this essay, into the particular reasons which we have for supposing that the vices and moral weakness of man can never be wholly overcome in this world.
