The sharp line of demarkation (abstract precision) which so clearly distinguished the trading nations of antiquity, such as the Phenicians and the Carthagenians, was due to that very predominance of agriculture. Capital as trading or money capital appears in that abstraction, where capital does not constitute as yet the predominating element of society. The Lombardians and the Jews occupied the same position among the agricultural nations of the middle ages.
As a further illustration of the fact that the same category plays different parts at different stages of society, we may mention the following: one of the latest forms of bourgeois society, viz. stock companies, appear also at its beginning in the form of the great chartered monopolistic trading companies. The conception of national wealth which is imperceptibly formed in the minds of the economists of the seventeenth century, and which partly continues to be entertained by those of the eighteenth century, is that wealth is produced solely for the state, but that the power of the latter is proportional to that wealth. It was as yet an unconsciously hypocritical way in which wealth announced itself and its own production as the aim of modern states considering the latter merely as a means to the production of wealth.
The order of treatment must manifestly be as follows: first, the general abstract definitions which are more or less applicable to all forms of society, but in the sense indicated above. Second, the categories which go to make up the inner organization of bourgeois society and constitute the foundations of the principal classes; capital, wage-labor, landed property; their mutual relations; city and country; the three great social classes, the exchange between them; circulation, credit (private). Third, the organization of bourgeois society in the form of a state, considered in relation to itself; the “unproductive” classes; taxes; public debts; public credit; population; colonies; emigration. Fourth, the international organization of production; international division of labor; international exchange; import and export; rate of exchange. Fifth, the world market and crises.
