I have not at all completed my design. But we must not leave the topic, without casting one glance into the interior recesses. It is a doctrine of philosophy, that man is a being of degrees; that there is nothing in the world, which is not repeated in his body; his body being a sort of miniature or summary of the world: then that there is nothing in his body, which is not repeated as in a celestial sphere in his mind: then, there is nothing in his brain, which is not repeated in a higher sphere, in his moral system. 5. Now these things are so in Nature. All things ascend, and the royal rule of economy is, that it should ascend also, or, whatever we do must always have a higher aim. Thus it is a maxim, that money is another kind of blood. _Pecunia alter sanguis_: or, the estate of a man is only a larger kind of body, and admits of regimen analogous to his bodily circulations. So there is no maxim of the merchant, _e.g._, "Best use of money is to pay debts;" "Every business by itself;" "Best time is present time;" "The right investment is in tools of your trade;" or the like, which does not admit of an extended sense. The counting-room maxims liberally expounded are laws of the Universe. The merchant’s economy is a coarse symbol of the soul’s economy. It is, to spend for power, and not for pleasure. It is to invest income; that is to say, to take up particulars into generals; days into integral eras,—literary, emotive, practical, of its life, and still to ascend in its investment. The merchant has but one rule, _absorb and invest_: he is to be capitalist: the scraps and filings must be gathered back into the crucible; the gas and smoke must be burned, and earnings must not go to increase expense, but to capital again. Well, the man must be capitalist. Will he spend his income, or will he invest? His body and every organ is under the same law. His body is a jar, in which the liquor of life is stored. Will he spend for pleasure? The way to ruin is short and facile. Will he not spend, but hoard for power? It passes through the sacred fermentations, by that law of Nature whereby everything climbs to higher platforms, and bodily vigor becomes mental and moral vigor. The bread he eats is first strength and animal spirits: it becomes, in higher laboratories, imagery and thought; and in still higher results, courage and endurance. This is the right compound interest; this is capital doubled, quadrupled, centupled; man raised to his highest power. The true thrift is always to spend on the higher plane; to invest and invest, with keener avarice, that he may spend in spiritual creation, and not in augmenting animal existence. Nor is the man enriched, in repeating the old experiments of animal sensation, nor unless through new powers and ascending pleasures, he knows himself by the actual experience of higher good, to be already on the way to the highest.
