any other kind.

Having thus settled, as it seemed to him beyond dispute, that manual labour, estimated in terms of time, is the sole source and measure of economic values or of wealth, Marx goes on to point out that, by the improvement of industrial methods, labour in the modern world has been growing more and more productive, so that each labour-hour results in an increased yield of commodities. Thus a man who a couple of centuries ago could have only just kept himself alive by the products of his entire labour-day, can now keep himself alive by the products of half or a quarter of it. The products of the remainder of his labour-day are what Marx called a "surplus value," meaning by this phrase all that output of wealth which is beyond what is practically necessary to keep the labourer alive. But what, he asks, becomes of this surplus? Does it go to the labourers who have produced it? No, he replies. On the contrary, as fast as it is produced, it is abstracted from the labourer in a manner, which he goes on to analyse, by the capitalist.

Marx here advances to the second stage of his argument. Capital, as he conceives of it, is the tools or instruments of production; and modern capital for him means those vast aggregates of machinery by the use of which in most industries the earlier implements have been displaced. Now, here, says Marx, the capitalist is sure to interpose with the objection that the increased output of wealth is due, not to labour, but to the machinery, and that the labourer, as such, has consequently no claim on it. But to this objection Marx is ready with the following answer—that the machinery itself is nothing but past labour in disguise. It is past labour crystallised, or embodied in an external form, and used by present labour to assist itself in its own operations. Every wheel, crank, and connecting-rod, every rivet in every boiler, owes its shape and its place to labour, and labour only. Labour, therefore—the labour of the average multitude—remains the sole agent in the production of wealth, after all.

Capital, however, as thus understood, has, he says, this peculiarity—that, being labour in an externalised and also in a permanent form, it is capable of being detached from the labourers and appropriated by other people; and the essence of modern capitalism is neither more nor less than this—the appropriation of the instruments of production by a minority who are not producers. So long as the implements of production were small and simple, and such that each could be used by one man or family, the divorce between the labourer and his implements was not easy to accomplish; but in proportion as these simple implements were developed into the aggregated mechanisms of the factory, each of which aggregates was used in common by hundreds and even by thousands of labourers, the link between the implement and the user was broken by an automatic process; for a single organised mechanism used by a thousand men could not, in the nature of things, be owned by each one of the thousand individually, and collective ownership by all of them was an idea as yet unborn. Under these circumstances, with the growth of modern machinery, the ownership of the implements of production passed, by what Marx looked upon as a kind of historical fatality, into the hands of a class whose activities were purely acquisitive, and had no true connection with the process of production at all; and this class, he said, constitutes the capitalists of the modern world.

The results of this process have, according to him, been as follows: Society has become divided into two contrasted groups—an enormous group, and a small one. The enormous group—the great body of every nation—the people—the labouring mass—the one true producing power—has been left without any implements by means of which its labour can exert itself, and these implements have been monopolised by the small group alone. The people at large, in fact, have become like the employés of a single mill-owner, who have no choice but to work within the walls of that mill or starve; and the possessing class at large has become like the owner of such a single mill, who, holding the keys of life and death in his hands, is able to impose on the mill-workers almost any terms he pleases as the price of admission to his premises and to the privilege of using his machinery; and the price which such an owner, so situated, will exact (such was the contention of Marx) inevitably must come, and historically has come, to this—namely, the entire amount of goods which the labouring class produces, except such a minimum as will just enable its members to keep themselves in working order, and to reproduce their kind. Thus all capital, as at present owned, all profits, and all interest on capital, are neither more nor less than thefts from the labouring class of commodities which are produced by the labouring class alone.

The argument of Marx is not, however, finished yet. There remains a third part of it which we still have to consider. Writing as he did, almost half a century ago, he said that the process of capitalistic appropriation had not—yet completed itself. A remnant of producers on a restricted scale survived, still forming a middle class, which was neither rich nor poor. But, he continued, in all capitalistic countries, a new movement, inevitable from the first, had set in, and its pace was daily accelerating. Just as the earlier capitalists swallowed up most of the small producers, so were the great capitalists swallowing up the smaller, and the middle class which survived was disappearing day by day. Wages, meanwhile, were regulated by an iron law. Under the system of capitalism it was an absolute impossibility that they could rise. As he put it, in language which has since become proverbial, "The rich are getting richer, the poor poorer, the middle class is being crushed out," and the time, he continued, was in sight already—it would arrive, according to him, before the end of the nineteenth century—when nothing would be left but a handful of idle and preposterous millionaires on the one hand, and a mass of miserable ragamuffins who provided all the millions on the other, having for themselves only enough food and clothing to enable them to move their muscles and protect their nakedness from the frost. Then, said Marx, when this contrast has completed itself, the situation will be no longer tolerable. "Then the knell of the capitalistic system will have sounded." The producers will assert themselves under the pressure of an irresistible impulse; they will repossess themselves of the implements of production of which they have been so long deprived. "The expropriators will in their turn be expropriated," and the labourers thenceforth owning the implements of production collectively, all the wealth of the world will forever afterwards be theirs.

This concluding portion of the gospel of Marx—its prophecies—has been in many of its details so completely falsified by events that even his most ardent disciples no longer insist on it. I have only mentioned it here because of the further light which it throws on what alone, in this discussion, concerns us—namely, the Marxian theory of labour as the sole producer of wealth, and the absolute nullity, so far as production goes, of every form of activity associated with the possession of capital, or with any class but the labouring.

This theory of production, then, which has been the foundation of socialism as a party—or, as Gronlünd, a disciple of Marx, calls it, "its idée mère"—and which is still its foundation for the great majority of socialists, we will now examine in detail, and, considering how complex are the processes of production in the modern world, ask how
