This appropriation is further determined by the manner in which it must be effected. It can only be effected through a union, which by the character of the proletariat itself can again only be a universal one, and through a revolution, in which, on the one hand, the power of the earlier mode of production and intercourse and social organisation is overthrown, and, on the other hand, there develops the universal character and the energy of the proletariat, without which the revolution cannot be accomplished; and in which, further, the proletariat rids itself of everything that still clings to it from its previous position in society.
Only at this stage does self-activity coincide with material life, which corresponds to the development of individuals into complete individuals and the casting-off of all natural limitations. The transformation of labour into self-activity corresponds to the transformation of the earlier limited intercourse into the intercourse of individuals as such. With the appropriation of the total productive forces through united individuals, private property comes to an end. Whilst previously in history a particular condition always appeared as accidental, now the isolation of individuals and the particular private gain of each man have themselves become accidental.
The individuals, who are no longer subject to the division of labour, have been conceived by the philosophers as an ideal, under the name "Man".
They have conceived the whole process which we have outlined as the evolutionary process of "Man", so that at every historical stage "Man" was substituted for the individuals and shown as the motive force of history. The whole process was thus conceived as a process of the self-estrangement of "Man", and this was essentially due to the fact that the average individual of the later stage was always foisted on to the earlier stage, and the consciousness of a later age on to the individuals of an earlier. Through this inversion, which from the first is an abstract image of the actual conditions, it was possible to transform the whole of history into an evolutionary process of consciousness.
Finally, from the conception of history we have sketched we obtain these further conclusions: (1) In the development of productive forces there comes a stage when productive forces and means of intercourse are brought into being, which, under the existing relationships, only cause mischief, and are no longer productive but destructive forces (machinery and money); and connected with this a class is called forth, which has to bear all the burdens of society without enjoying its advantages, which, ousted from society, is forced into the most decided antagonism to all other classes; a class which forms the majority of all members of society, and from which emanates the consciousness of the necessity of a fundamental revolution, the communist consciousness, which may, of course, arise among the other classes too through the contemplation of the situation of this class. (2)
The conditions under which definite productive forces can be applied are the conditions of the rule of a definite class of society, whose social power, deriving from its property, has its practical-idealistic expression in each case in the form of the State; and, therefore, every revolutionary struggle is directed against a class, which till then has been in power. [4] (3) In all revolutions up till now the mode of activity always remained unscathed and it was only a question of a different distribution of this activity, a new distribution of labour to other persons, whilst the communist revolution is directed against the preceding mode of activity, does away with labour, and abolishes the rule of all classes with the classes themselves, because it is carried through by the class which no longer counts as a class in society, is not recognised as a class, and is in itself the expression of the dissolution of all classes, nationalities, etc. within present society; and (4) Both for the production on a mass scale of this communist consciousness, and for the success of the cause itself, the alteration of men on a mass scale is, necessary, an alteration which can only take place in a practical movement, a revolution; this revolution is necessary, therefore, not only because the ruling class cannot be overthrown in any other way, but also because the class overthrowing it can only in a revolution succeed in ridding itself of all the muck of ages and become fitted to found society anew.
