Fair use statement:
“By the manner in which man has been scored by some political writers and system-makers, one would think they took him for a Polypus. Montesquieu split him into two halves, one of them may be rendered good (by one cause,) while the other is rendered evil by another cause. The laws of perfection derived from religion, have more for their object the goodness of the man who observes them, than that of the society in which they are observed. Civil laws on the contrary have more for their object the moral goodness of men in general, than that of individuals! But what is it that a writer means when he talks of good men making up a community not good, and of a good community made up of men not good?
“Bishop Warburton has [gone farther—he has] made three selves out of a man; and lest they should be surprised at finding what’s done to them—not so, only, says he, but if I find I want more, I make as many more out of you as I please. What! three distinct men out of one man? Yes, three distinct men to be sure—What do you think I am talking about? What do you take me for? A metaphor-monger, a romancer? Know that I am a logician; mind me, now—I am going to prove it as plain as the nose upon your face. Maj.: A distinct will and personality make a distinct man. Do you deny it? Have at you, then.”
