This inhumanity of mercenary commerce is the more notable because it is a fulfilment of the law that the corruption of the best is the worst. For as, taking the body natural for symbol of the body politic, the governing and forming powers may be likened to the brain and the labouring to the limbs, the mercantile, presiding over circulation and communication of things in changed utilities is symbolized by the heart; which, if it harden, all is lost. And this is the ultimate lesson which the leader of English intellect meant for us (a lesson, indeed, not all his own, but part of the old wisdom of humanity), in the tale of the "Merchant of Venice"; in which the true and incorrupt merchant,--kind and free, beyond every other Shakespearian conception of men,--is opposed to the corrupted merchant, or usurer; the lesson being deepened by the expression of the strange hatred which the corrupted merchant bears to the pure one, mixed with intense scorn-- "This is the fool that lent out money gratis; look to him, jailor," (as to lunatic no less than criminal); the enmity, observe, having its symbolism literally carried out by being aimed straight at the heart, and finally foiled by a literal appeal to the great moral law that flesh and blood cannot be weighed, enforced by "Portia" ("Portion"), the type of divine Fortune,[98] found, not in gold, nor in silver, but in lead, that is to say, in endurance and patience, not in splendour; and finally taught by her lips also, declaring, instead of the law and quality of "merces," the greater law and quality of mercy, which is not strained, but drops as the rain, blessing him that gives and him that takes. And observe that this "mercy" is not the mean "Misericordia," but the mighty "Gratia," answered by Gratitude (observe Shylock's leaning on the, to him detestable, word gratis, and compare the relation of Grace to Equity given in the second chapter of the second book of the "Memorabilia"); that is to say, it is the gracious or loving, instead of the strained, or competing manner, of doing things, answered, not only with "merces" or pay, but with "merci," or thanks. And this is indeed the meaning of the great benediction, "Grace, mercy, and peace," for there can be no peace without grace (not even by help of rifled cannon),[99] nor even without triplicity of graciousness, for the Greeks, who began with but one Grace, had to open their scheme into three before they had done.
