The partisans of critical communism recognized that history has the right to follow its course. The bourgeois phase can be outgrown and it will be. But as long as it exists it has its laws. The relativity of these consists in the fact that they grow and develop in certain determined conditions, but their relativity is not simply the opposite of necessity, a mere appearance, a soap-bubble. These laws may disappear and they will disappear by the very fact of the change of society, but they do not yield to the arbitrary suggestion which demands a change, proclaims a reform, or formulates a programme. Communism makes common cause with the proletariat because in this resides the revolutionary force which, bursts, breaks, shakes and dissolves the present social form and creates in it, little by little, new conditions; or to be more exact, the very fact of its movement shows to us that these new conditions are already born. The theory of the class struggle was found. It was seen to appear both in the origins of the bourgeoisie (whose intrinsic _processus_ was already illustrated by the science of economics), and in this new appearance of the proletariat. The relativity of economic laws was discovered, but at the same time their relative necessity was understood. Herein lies the whole method and justification of the new materialistic conception of history. Those deceive themselves who, calling it the economic interpretation of history, think they understand it completely. That designation is better suited, and is only suited, to certain analytic attempts,[25] which, taking separately and in a distinct fashion on the one side the economic forms and categories, and on the other, for example, law, legislation, politics, customs,--proceed to study the reciprocal influences of the different sides of life considered in an abstract fashion. Quite different is our position. Ours is the organic conception of history. The totality of the unity of social life is the subject matter present to our minds. It is economics itself which dissolves in the course of one process, to reappear in as many morphological stages, in each of which it serves as a substructure for all the rest. Finally, it is not our method to extend the so-called economic factor isolated in an abstract fashion over all the rest, as our adversaries imagine, but it is, before everything else, to form an historic conception of economics and to explain the other changes by means of its changes. Therein lies our answer to all the criticisms which come to us from all the domains of learned ignorance, not excepting the socialists who are insufficiently grounded and who are sentimental or hysterical. And we explain our position thus as Marx has done in his Capital, not the first book of critical communism, but the last great book of bourgeois economics.
