Dr. Johnson’s argument is exclusively directed against the political and moral propriety of the institution of slavery as a state or condition of man anywhere, instead of the true question at issue. The argument, taken as a whole, is, therefore, a sophism, of the order which dialecticians call “_ignoratio elenchi_;” a dodging of the question; a substitution of something for the question which is not; a practice common among the pert pleaders of the day—sometimes, doubtless, without their own perception of the fact. In regard to him who uses this sophism to effect the issue, the conclusion is inevitable,—he is either dishonest or he is ignorant of his subject. And when we come to examine this celebrated production as an argument against the moral propriety of the existence of the institution of slavery in the world, we shall find every pillar presented for its foundation a mere sophism, now quite distinctly, and again more feebly enunciated, as if with a more timid tongue, and left to inquiry, adorned by festoons of doubt and supposition. We shall requote some portions, with a view to their more particular consideration. And, first, “Yet it may be doubted whether slavery can ever be supposed the natural condition of man.” This clause, when put in the crucible, reads, “Yet slavery can never exist in conformity to the law of God.” Whoever doubts this to be the sense, we ask him to suppose what the sense is! The author did not choose these few words to express the proposition, because the law of God _could_ readily be produced in contradiction: “_Whosoever committeth sin is the servant_ (δοῦλος, _doulos_, SLAVE) _of sin_.” Besides, then, he loses the benefit of the sophism,—the substitution of the condition of man in his fallen state, through the ambiguity of the word “natural,” for the condition of the first man, fresh from the hand of the Creator. This sophism is one of great art and covertness; so much so, that it takes its character rather from its effect on the mind than from its language; and we therefore desire him who reads, to notice the whole chain of thought passing in the author’s mind,—lest he forget how our present state is the subject of contemplation offered as data, when, on the word “natural,” as if it were a potter’s wheel, our _original condition_ is turned to the front, a postulate, from which we are left to compare and conclude.
