Now, I have pressed this upon you at more length than is needful or proportioned to our present purposes of inquiry, because I would not for the first time speak to you on this subject of political economy without clearly stating what I believe to be its first grand principle. But its bearing on the matter in hand is chiefly to prevent you from at once too violently dissenting from me when what I may state to you as advisable economy in art appears to imply too much restraint or interference with the freedom of the patron or artist. We are a little apt, though, on the whole a prudent nation, to act too immediately on our impulses, even in matters merely commercial; much more in those involving continual appeals to our fancies. How far, therefore, the proposed systems or restraints may be advisable, it is for you to judge; only I pray you not to be offended with them merely because they _are_ systems and restraints. Do you at all recollect that interesting passage of Carlyle, in which he compares, in this country and at this day, the understood and commercial value of man and horse; and in which he wonders that the horse, with its inferior brains and its awkward hoofiness, instead of handiness, should be always worth so many tens or scores of pounds in the market, while the man, so far from always commanding his price in the market, would often be thought to confer a service on the community by simply killing himself out of their way? Well, Carlyle does not answer his own question, because he supposes we shall at once see the answer. The value of the horse consists simply in the fact of your being able to put a bridle on him. The value of the man consists precisely in the same thing. If you can bridle him, or which is better, if he can bridle himself, he will be a valuable creature directly. Otherwise, in a commercial point of view, his value is either nothing, or accidental only. Only, of course, the proper bridle of man is not a leathern one: what kind of texture it is rightly made of, we find from that command, "Be ye not as the horse or as the mule which have no understanding, whose mouths must be held in with bit and bridle." You are not to be without the reins, indeed, but they are to be of another kind; "I will guide thee with mine Eye." So the bridle of man is to be the Eye of God; and if he rejects that guidance, then the next best for him is the horse's and the mule's, which have no understanding; and if he rejects that, and takes the bit fairly in his teeth, then there is nothing left for him than the blood that comes out of the city, up to the horsebridles.
