"Man's earliest arms were fingers, teeth, and nails,
And stones, and fragments from the branching woods;
Then copper next; and last, as later traced,
The tyrant iron."

We are at no loss, then, to explain the origin of Capital and its motives. Tools are invented and employed for no other reason than this, that, by means of their help, the human efforts are lessened relatively to the given satisfactions. Since it requires tools to make tools, the progress of this branch of capital must have been relatively slow at first; but, since every advance in mechanical contrivance makes still further advances easier, there is a natural tendency, which facts abundantly exemplify, to a more and more rapid progression in the number and perfection of all implements of production. The same motive that impelled to the first invention, has impelled to the whole series of inventions since, and will constantly impel to further inventions till the end of time. Every step of this progress gives birth to a larger and still larger proportion of satisfactions relatively to efforts; marks an increasing control on the part of man over the powers of Nature; and gives promise for the time to come of greater advantages still in both of these directions. The powers of Nature, such as those which make the grain grow, bring the tree down, turn the water-wheel, impel the locomotive, and send the message round the world, all stand ready to slave in the service of man; but in order to make their aid available for human purposes, there must be a plough, an axe, a wheel, an engine, an electric machine; and it is because capital brings gratuitous natural forces into service, and the more so as capital progresses, that the Value of those commodities produced by the aid of capital tends constantly to decline as compared with those commodities, in the production of which capital conspires less.

It is already plain, that the class, Capital, is a smaller and a peculiar sub-class under the great class, Valuables; nothing can become Capital until it first become a Valuable, and then be capitalized by a distinct act or intention on the part of the owner to reserve it in his own hands as an aid in further production, or transfer it to other hands to be so used, he meanwhile receiving profits as the reward of his abstinence; only a transferable valuable, accordingly, can become Capital in any case, that is to say, it must be either a Commodity or a Credit, since personal services, though they may be sold, cannot be put over into the hands of another to be used in production, and therefore cannot become Capital in any case; and the chief peculiarity of this sub-class, Capital, is, unlike the three great classes of Valuables, each of which is utterly distinct from the other two, so that a Commodity can never become a Credit or a personal Service either of the others, that Capital as a class has extremely flexible limits, and consequently certain Commodities and Credits may easily enough be Capital to-day, and fall back to-morrow into their respective classes of mere Valuables and the next day come out from the class Non-Capital into the class Capital again. The same commodities and credits may be capital at one time, and non-capital at another, though they must be valuable all the time, or cease to be commodities and credits. When it is said that a young man's talents and skill are his "capital," the word of course is used in a metaphorical sense, and the meaning is, that skill and talents are like capital in some respects. Popular language is not scientific.

Cicero wrote long ago: "Optimum et in privatis familiis et in republica vectigal est parsimonia." Abstinence is the best means of revenue as well in private families as in the State. The source of Capital in a distinct act of will saving or sparing from present use (parsimonia) a valuable commodity or credit, and the quick nature of Capital as adding to itself (vectigal) in profits, are both brought out in this Latin maxim, which is rather an expression of an old and ingrained Roman sentiment than anything original with Cicero. It is the very nature as well as the very name of "Capital" to increase itself by rapid increments. It is as well the Stream as the Source. For example, any sum of money soon doubles itself when put out at compound interest, because the original sum increases day and night until it be repaid. It is of the essence of every form of Capital to make growth, because its sole purpose as such is to become an aid to future and further production. A trowel in the hands of a mason, which is capital, pays for itself every day he works with it, and perhaps every hour of the day, in the increased production wrought by means of it. The wheel, which free water turns, though a costly implement, repays that cost a hundred fold in the additional bushels of wheat turned into flour through its aid as capital. So of all implements. So of all machinery. So of all means of transportation: ships, canals, railroads.

There was a strange prejudice in ancient and mediæval times against this natural increase of capital out of its own bowels, as it were, owing probably to this dictum of Aristotle: "For usury is most reasonably detested, as the increase of our fortune arises from the money itself, and not by employing it for the purpose for which it was intended." In 1360, a French bishop, Nicole Oresme, repeats the error of Aristotle under the same rhetorical image: "It is monstrous and contrary to Nature that a barren stock should give birth, that a thing sterile in its whole being should fructify and be multiplied from itself, and such a thing is money." Even Shakspeare catches up the old figure: "Is your gold and silver ewes and rams?" Shylock answers: "I cannot tell; I make it breed as fast." In the light of the three requisites of Production, in the light of the purpose and wisdom of God in arranging the active forces of this world, the prejudice in question disappears, and intelligence rejoices in the ever-increasing use of Capital as the handmaid of Labor, in the quick and sure reward of him who practises abstinence, in the production of commodities constantly made easier and cheaper in all directions, in a scale of comforts for the masses of men assuredly rising, in a divinely appointed force lifting like Christianity itself upon the otherwise sagging condition of mankind.

Capital assumes but two economical forms, namely, Circulating Capital and Fixed Capital. Circulating Capital is all those capitalized products, whether commodities or credits, the returns for the sale or use of which are derived at once and once for all. All circulating capital will be found in one or other of the following sub-forms: (1) raw materials; (2) wages paid out in view of an ultimate profit; (3) completed products on hand for sale; and (4) products bought and held for the sake of resale. The crucial test of circulating capital is the question, Are the returns to be secured by the single use or single transfer of that particular product? Tools, for example, in the hands of him who has manufactured them for sale is circulating capital. Fixed Capital is all those capitalized products, which are purchased or held with a view of deriving an income from their delayed and repeated use. All fixed capital will probably be found in one or other of the sub-forms following: (1) tools and machinery in use; (2) buildings used for productive purposes; (3) permanent improvements in land parcels; (4) investments in aid of locomotion and transportation; (5) products rented or retained for that purpose; and (6) the national money considered as a whole.

2. We will next look at the essential Conditions of the production of Commodities. These are also three, as are the Requisites, namely, Association, Invention, Freedom. More or less will men make and sell to one another commodities in any state of society, in which there is permitted any considerable degree of association of men with men locally or commercially, in which is encouraged in any way the universal spirit of invention or the desire to get hard things done easier, and in which some degree of liberty of action and security of property and equality of privileges is guaranteed; but it is very plain, that the production of commodities will increase in all directions and become the greatest in that age and country when and where are allowed the closest ties of human association both in place and in commerce, the freest scope and largest rewards of inventive genius, and the highest possible degree of liberty and security and equality of rights. Let us illustrate from a state of things in the southern half of the United States during the first half of the nineteenth century. For the most part the land owners lived on isolated plantations widely separate from one another, these plantations were cultivated by gangs of slaves, a system that tends to bring all manual labor into contempt, the poor whites scattered in hamlets felt themselves above the slaves and beneath the masters, intercourse between the three classes was little, opportunity to better essentially their condition was denied to all three alike, there were but few cities sprinkled over the vast territory and these relatively small, the only commodity produced on a large scale was raw cotton, the simple device for ginning this had been invented in the decade preceding by a college boy from Connecticut, the agricultural implements were of the rudest kind, even the coarse shoes for the slaves were bought at the North;—in short, the degree of association and invention and freedom was each so low, that the production of commodities was exceedingly small, even as compared with what that production became in one quarter of a century after the abolition of slavery.

(a) Association. If we may continue for purpose of illustration our childhood trust in the story of De Foe, Robinson Crusoe came to lead a very tolerable life upon his desolate island by means of his own industry directed so as to satisfy his own wants by his own efforts. He did everything for himself, and had no opportunity to buy anything or sell anything. The whole course of such an isolated life could never develop the idea of Value, would require no such word as Commodities or suggest their production, and such a man while solitary upon his island could not possess Property in the true sense of that word. Association is the first main condition of Production, because of the natural obstacles interposed between the isolated man and the supply of his various wants. If any one man try to surmount a considerable number of these natural obstacles, he must miserably fail, because his powers are not adequate to the task; and hence it follows, that, in a state of isolation, men's wants exceed their powers; but now let the same man devote himself to overcome a single class of obstacles, for instance, those in the way of procuring suitable clothing, and his powers are adequate to this, he soon acquires skill in it, he learns to avail himself of the free help of Nature and the facilitating processes of art, he is able to realize large products along his line, and is now ready to offer his surplus in exchange with other men, who meanwhile have been giving themselves each to another class of obstacles, have concentrated efforts and skill upon them, have succeeded by the help of Nature and art in surmounting them, and are now ready to offer their surplus commodities in exchange for others; and, the exchanges beginning to be made in all directions, men find that they thus obtain vastly greater satisfactions for their various desires than they could possibly get by direct efforts: so that we may even say, that, in a state of society through association, men's powers tend to overtake their wants.

Without association with his fellow-men, there is no creature so helpless, so unable to reach his true end, as is man; and therefore it is, that the impulse to association is one of the strongest of our natural impulses. Men come together, as it were by instinct, into society; and, thus associating themselves together, it is soon discovered, not only that there are various desires in the different members of the community, which are now readily met by coöperation and mutual exchange, but also that there are very different powers in the different individuals in relation to those obstacles which are to be surmounted. The tastes and aptitudes of different men are very diverse. There is a great diversity in natural gifts. One man has physical strength, another mechanical ingenuity, a third a philosophical turn, and a fourth a bent and genius for traffic. Now, then, Nature speaks in as loud a voice as she can utter, in favor of such a degree of association and exchange as shall allow a free development of these varying capacities, while they work upon the obstacles to the gratification of men's wants, which lie appropriately opposite to them.

Men must come together either locally or commercially, must learn each other's wants, must compare with each other powers and tastes and opportunities, must come to have some confidence in each other, and then they will begin by rendering mutual services back and forth to experience the better satisfactions and the new strength that exchanges bring. Whatever improves the character of men, and thus leads to greater confidence among them, will enlarge their commerce, and knit closer and wider ties of association and production. Neighborhood associations and productions soon create a surplus to be exchanged for something else with other neighborhoods; parts of single nations however remote from each other find a relative diversity of advantage and an increasing profit in connecting themselves by the ties of trade; and the separate nations learn, though late, that they are only one great family for the grand ends of production and progress. Even within the single nation, there is a strong tendency for particular trades to localize themselves in one spot, as for instance, the manufacture of skin gloves has centered itself for the United States in Gloversville, N. Y.; and so in the great cities that are centres of distribution, for example, the wholesale grocers of St. Paul are on one street, the dry goods houses of Boston are in close proximity, and the booksellers of New York are tending towards each other in place.
