before Kopernicus, it was believed that the earth remained stationary, while the sun turned round it. The Polish genius demonstrated that what occurred was the exact contrary. And so, up to the time of Marx, the point of view taken by social science, was that of "human nature;" and it was from this point of view that men attempted to explain the historical movement of humanity. To this the point of view of the German genius is diametrically opposed. While man, in order to maintain his existence, acts upon nature outside himself, he alters his own nature. The action of man upon the nature outside himself, pre-supposes certain instruments, certain means of production; according to the character of their means of production men enter into certain relations within the process of production (since this process is a social one), and according to their relations in this social process of production, their habits, their sentiments, their desires, their methods of thought and of action, in a word, their nature, vary. Thus it is not human nature which explains the historical movement; it is the historical movement which fashions diversely human nature.

But if this is so, what is the value of all the more or less laborious, more or less ingenious enquiries into "perfect legislation" and the best of possible social organisations? None; literally none! They can but bear witness to the lack of scientific education in those who pursue them. Their day is gone for ever. With this old point of view of human nature must disappear the Utopias of every shade and colour. The great revolutionary party of our day, the International Social-Democracy, is based not upon some "new conception" of human nature, nor upon any abstract principle, but upon a scientifically demonstrable economic necessity. And herein lies the real strength of this party, making it as invincible as the economic necessity itself.

"The means of production and exchange on whose foundation the bourgeoisie built itself up, were generated in feudal society. At a certain stage in the development of these means of production and exchange, the conditions under which feudal society produced and exchanged, the feudal organisation of agriculture and manufacturing industry, in one word, the feudal relations of property become no longer compatible with the already developed productive forces, they become so many fetters. They had to be burst asunder; they were burst asunder. Into their place stepped free competition, accompanied by a social and political constitution adapted to it, and by the economical and political sway of the bourgeois class. A similar movement is going on before our own eyes. Modern bourgeois society, with its relations of production, of exchange, and of property, a society that has conjured up such gigantic means of production and of exchange, is like the sorcerer, who is no longer able to control the powers of the nether world whom he has called up by his spells. For many a decade past the history of industry and commerce is but the history of the revolt of modern productive forces against the property relations that are the conditions for the existence of the bourgeoisie and its rule. It is enough to mention the commercial crises that by their periodical return put on its trial, each time more threateningly, the existence of the entire bourgeois society.... The weapons with which the bourgeoisie felled feudalism to the ground are now turned against the bourgeoisie itself."[4]

The bourgeoisie destroyed the feudal conditions of property; the proletariat will put an end to the bourgeois conditions of property. Between the proletariat and the bourgeoisie a struggle, an implacable war, a war to the knife, is as inevitable as, was in its way, the struggle between the bourgeoisie and the privileged estates. But every class war is a political war. In order to do away with feudal society the bourgeoisie had to seize upon political power. In order to do away with capitalist society the proletariat must do the same. Its political task is therefore traced out for it beforehand by the force of events themselves, and not by any abstract consideration.

It is a remarkable fact that it is only since Karl Marx that Socialism has taken its stand upon the class war. The Utopian Socialists had no notion—even an inexact one—of it. And in this they lagged behind their contemporary theorists of the bourgeoisie, who understood very well the historical significance at any rate of the struggle of the third estate against the nobles.

If every "new conception" of human nature seemed to supply very definite indications as to the organisation of "the society of the future," Scientific Socialism is very chary of such speculations. The structure of society depends upon the conditions of its productive forces. What these conditions will be when the proletariat is in power we do not know. We now know but one thing—that the productive forces already at the disposal of civilised humanity imperatively demand the socialisation and systematised organisation of the means of production. This is enough to prevent our being led astray in our struggle against "the reactionary mass." "The Communists, therefore, are practically the most advanced and resolute section of the working class parties of every country ... theoretically they have over the great mass of the proletariat the advantage of clearly understanding the line of march, the conditions, and the ultimate general results of the proletarian movement."[5] These words, written in 1848, are to-day incorrect only in one sense: they speak of "working class parties" independent of the Communist party; there is to-day no working class party which does not more or less closely follow the flag of Scientific Socialism, or, as it was called in the Manifesto, "Communism."

Once again, then, the point of view of the Utopian Socialists, as indeed of all social science of their time, was human nature, or some abstract principle deriving from this idea. The point of view of the social science, of the Socialism of our time is that of economic reality, and of the immanent laws of its evolution.

It is easy, therefore, to form an idea of the impression made upon modern Socialists by the arguments of the bourgeois theorists who sing ceaselessly the same old song of the incompatibility of human nature and communism. It is as though one would wage war upon the Darwinians with arms drawn from the scientific arsenal of Cuvier's time. And a most noteworthy fact is that the "evolutionists" like Herbert Spencer, themselves are not above piping to the same tune.[6]

And now let us see what relation there may be between modern Socialism and what is called Anarchism.
