genesis of this struggle; it details its evolutionary rhythm, and predicts its final result.

In that conception of history is embodied the whole doctrine of scientific communism. From that moment the theoretical adversaries of socialism have no longer had to discuss the abstract possibility of the democratic socialization of the means of production;[2] as if it were possible in this question to rest their judgment upon inductions based upon the general and common aptitudes of what they characterize as human nature. Thenceforth, the question was to recognize, or not to recognize, in the course of human events the necessity which stands over and above our sympathy and our subjective assent. Is or is not society in the countries most advanced in civilization organized in such a way that it will pass into communism by the laws inherent in its own future, once conceding its present economic structure and the friction which it necessarily produces within itself, and which will end by breaking and dissolving it? That is the subject of all discussion since the appearance of this theory and thence follows also the rule of conduct which imposes itself upon the action of the socialist parties whether they be composed of proletarians alone or whether they have in their ranks men who have come out from the other classes and who join as volunteers the army of the proletariat.

That is why we voluntarily accept the epithet of scientific, provided we do not thus confuse ourselves with the positivists, sometimes embarrassing guests, who assume to themselves a monopoly of science; we do not seek to maintain an abstract and generic thesis like lawyers or sophists, and we do not plume ourselves on demonstrating the reasonableness of our aims. Our intentions are nothing less than the theoretical expression and the practical explanation of the data offered us by the interpretation of the process which is being accomplished among us and about us and which has its whole existence in the objective relations of social life of which we are the subject and the object, the cause and the effect. Our aims are rational, not because they are founded on arguments drawn from the reasoning of reason, but because they are derived from the objective study of things, that is to say, from the explanation of their process, which is not, and which cannot be, a result of our will but which on the contrary triumphs over our will and subdues it.

Not one of the previous or subsequent works of the authors of the Manifesto themselves, although they have a much more considerable scientific leaning, can replace the Manifesto or have the same specific efficacy. It gives us in its classic simplicity the true expression of this situation; the modern proletariat exists, takes its stand, grows and develops in contemporary history as the concrete subject, the positive force whose necessarily revolutionary action must find in communism its necessary outcome. And that is why this work while giving a theoretical base to its prediction and expressing it in brief, rapid and concise formulae, forms a storehouse, or rather an inexhaustible mine of embryonic thoughts which the reader may fertilize and multiply indefinitely; it preserves all the original and originating force of the thing which is but lately born and which has not yet left the field of its production. This observation is intended especially for those who applying a learned ignorance, when they are not humbugs, charlatans, or amiable dilettanti, give to the doctrine of critical communism precursors, patrons, allies and masters of every class without any respect for common sense and the most vulgar chronology. Or again, they try to bring back our materialistic conception of history into the theory of universal evolution which to the minds of many is but a new metaphor of a new metaphysics. Or again they seek in this doctrine a derivative of Darwinism which is an analogous theory only in a certain point of view and in a very broad sense; or again they have the condescension to favor us with the alliance or the patronage of that positive philosophy which extends from Comte, that degenerate and reactionary disciple of the genial Saint-Simon, to Spencer, that quintessence of anarchical capitalism, which is to say that they wish to give us for allies our most open adversaries.

It is to its origin that this work owes its fertilizing power, its classic strength, and the fact that it has given in so few pages the synthesis of so many series and groups of ideas.[3]

It is the work of two Germans, but it is not either in its form or its basis the expression of personal opinion. It contains no trace of the imprecations, or the anxieties, or the bitterness familiar to all political refuges and to all those who have voluntarily abandoned their country to breathe elsewhere freer air. Neither do we find in it the direct reproduction of the conditions of their own country, then in a deplorable political state and which could not be compared to those of France and England socially and economically, except as regards certain portions of their territory. They brought to their work, on the contrary, the philosophic thought which alone had placed and maintained their country upon the level of contemporary history:—this philosophic thought which in their hands was undergoing that important transformation which permitted materialism, already renewed by Feuerbach combined with dialectics, to embrace and understand the movement of history in its most secret and until then unexplored causes,—unexplored because hidden and difficult to observe. Both were communists and revolutionists, but they were so neither by instinct, by impulse nor by passion. They had elaborated an entirely new criticism of economic science and they had understood the connection and the historic meaning of the proletarian movement on both sides of the Channel, in France and in England, before they were called to give in the Manifesto the programme and the doctrine of the Communist League. This had its center in London and numerous branches on the continent; it had behind it a life and development of its own.

Engels had already published a critical essay in which passing over all subjective and one-sided corrections he brought out for the first time in an objective fashion the criticism of political economy and of the antitheses inherent in the data and the concepts of that economy itself, and he had become celebrated by the publication of a book on the condition of the English working class which was the first attempt to represent the movements of the working class as the result of the workings of the forces and means of production.[4] Marx, in the few years preceding, had become known as a radical publicist in Germany, Paris and Brussels. He had conceived the first rudiments of the materialistic conception of history. He had made a theoretically victorious criticism of the hypotheses of Proudhon and the deductions from his doctrine, and had given the first precise explanation of the origin of surplus value as a consequence of the purchase and the use of labor power, that is to say the first germ of the
