conceptions which were later demonstrated and explained in their connection and their details in Capital. Both men were in touch with the revolutionists of the different countries of Europe, notably France, Belgium and England; their Manifesto was not the expression of their personal theory, but the doctrine of a party whose spirit, aim and activity already formed the International Workingmen’s Association.

These are the beginnings of modern socialism. We find there the line which separates it from all the rest.

The Communist League grew out of the League of the Just; the latter in its turn had been formed with a clear consciousness of its proletarian aims through a gradual specialization of the generic group of the refugees, the exiles. As a type, bearing within itself in an embryonic design the form of all the later socialist and proletarian movements, it had traversed the different phases of conspiracy and of equalitarian socialism. It was metaphysical with Gruen and utopian with Weitling. Having its principal seat at London it was interested in the Chartist movement and had had some influence over it. This movement showed by its disordered character, because it was neither the fruit of a premeditated experience, nor the embodiment of a conspiracy or of a sect, how painful and difficult was the formation of a proletarian political party. The socialist tendency was not manifested in Chartism until the movement was near its end and was nearly finished (though Jones and Horner can never be forgotten). The League everywhere carried an odor of revolution, both because the thing was in the air and because its instinct and method of procedure tended that way: and as long as the revolution was bursting forth effectively, it provided itself, thanks to the new doctrine of the Manifesto, with an instrument of orientation which was at the same time a weapon for combat. In fact, already international, both by the quality and differences of origin of its members, and still more by the result of the instinct and devotion of all, it took its place in the general movement of political life as the clear and definite precursor of all that can to-day be called modern socialism, if by modern we mean not the simple fact of extrinsic chronology but an index of the internal or organic process of society.

A long interruption from 1852 to 1864 which was the period of political reaction and at the same time that of the disappearance, the dispersion and the absorption of the old socialist schools, separates the International of the Arbeiterbildungsverein of London, from the International properly so called, which, from 1864 to 1873, strove to put unity into the struggle of the proletariat of Europe and America. The action of the proletariat had other interruptions especially in France, and with the exception of Germany, from the dissolution of the International of glorious memory up to the new International which lives to-day through other means and which is developing in other ways, both of them adapted to the political situation in which we live, and based upon riper experience. But just as the survivors of those who in December, 1847, discussed and accepted the new doctrine, have re-appeared on the public scene in the great International, and later again in the new International, the Manifesto itself has also re-appeared little by little and has made the tour of the world in all the languages of the civilized countries, something which it promised to do but could not do at the time of its first appearance.

There was our real point of departure; there were our real precursors. They marched before all the others, early in the day, with a step rapid but sure, over this exact road which we were to traverse and which we are traversing in reality. It is not proper to give the name of our precursors to those who followed ways which they later had to abandon, or to those who, to speak without metaphor, formulated doctrines and started movements, doubtless explicable by the times and circumstances of their birth, but which were later outgrown by the doctrine of critical communism, which is the theory of the proletarian revolution. This does not mean that these doctrines and these attempts were accidental, useless and superfluous phenomena. There is nothing irrational in the historic course of things because nothing comes into existence without reason, and thus there is nothing superfluous. We cannot even to-day arrive at a perfect understanding of critical communism without mentally retracing these doctrines and following the processes of their appearance and disappearance. In fact these doctrines have not only passed, they have been intrinsically outgrown both by reason of the change in the conditions of society and by reason of the more exact understanding of the laws upon which rest its formation and its process.

The moment at which they enter into the past, that is to say, that at which they are intrinsically outgrown, is precisely that of the appearance of the Manifesto. As the first index of the genesis of modern socialism, this writing, which gives only the most general and the most easily accessible features of its teaching, bears within itself traces of the historic field within which it is born, which was that of France, England and Germany. Its field for propaganda and diffusion has since become wider and wider, and it is henceforth as vast as the civilized world. In all countries in which the tendency to communism has developed through antagonisms under aspects different but every day more evident between the bourgeoisie and the proletariat, the process of its first formation is wholly or partly repeated over and over. The proletarian parties which are formed little by little have traversed anew the stages of formation which their precursors traversed at first; but this process has become from country to country and from year to year always more rapid by reason of the greater evidence, the pressing necessity and energy of the antagonisms, and because it is easier to assimilate a doctrine and a tendency than to create both for the first time. Our co-workers of 50 years ago were also from this point of view international, since by their example they started the proletariat of the different nations upon the general march which labor must accomplish.

But the perfect theoretical knowledge of socialism to-day, as before, and as it always will be, lies in the understanding of its historic necessity, that is to say, in the consciousness of the manner of its genesis; and this is precisely reflected, as in a limited field of observation and in a hasty example, in the formation of the Manifesto. It was intended for a weapon of war and thus it bears upon its own exterior the traces of its origin. It contains more substantial declarations than demonstrations. The demonstration rests entirely in the imperative force of its necessity. But we may retrace the process of this formation and to retrace it is to understand truly the doctrine of the Manifesto. There is an analysis which while separating in theory the factors of an organism destroys them in so far as they are elements contributing to the unity of the whole. But there is another analysis, and this alone permits us to understand history, which only distinguishes and separates the elements to find again in them the objective necessity of their co-operation toward the total result.

It is now a current opinion that modern socialism is a normal and thus an inevitable product of history. Its political action, which may in future involve delays and set-backs but never henceforth a total absorption, began with the International. Nevertheless the Manifesto precedes it. Its teaching is
