It follows from all we have been saying up till now that the communal relationship into which the individuals of a class entered, and which was determined by their common interests over against a third party, was always a community to which these individuals belonged only as average individuals, only insofar as they lived within the conditions of existence of their class -- a relationship in which they participated not as individuals but as members of a class. With the community of revolutionary proletarians, on the other hand, who take their conditions of existence and those of all members of society under their control, it is just the reverse; it is as individuals that the individuals participate in it. It is just this combination of individuals (assuming the advanced stage of modern productive forces, of course) which puts the conditions of the free development and movement of individuals under their control -- conditions which were previously abandoned to chance and had won an independent existence over against the separate individuals just because of their separation as individuals, and because of the necessity of their combination which had been determined by the division of labour, and through their separation had become a bond alien to them. Combination up till now (by no means an arbitrary one, such as is expounded for example in the Contrat social, but a necessary one) was an agreement upon these conditions, within which the individuals were free to enjoy the freaks of fortune (compare, e.g., the formation of the North American State and the South American republics). This right to the undisturbed enjoyment, within certain conditions, of fortuity and chance has up till now been called personal *******. These conditions of existence are, of course, only the productive forces and forms of intercourse at any particular time.
Forms of Intercourse Communism differs from all previous movements in that it overturns the basis of all earlier relations of production and intercourse, and for the first time consciously treats all natural premises as the creatures of hitherto existing men, strips them of their natural character and subjugates them to the power of the united individuals. Its organisation is, therefore, essentially economic, the material production of the conditions of this unity; it turns existing conditions into conditions of unity. The reality, which communism is creating, is precisely the true basis for rendering it impossible that anything should exist independently of individuals, insofar as reality is only a product of the preceding intercourse of individuals themselves. Thus the communists in practice treat the conditions created up to now by production and intercourse as inorganic conditions, without, however, imagining that it was the plan or the destiny of previous generations to give them material, and without believing that these conditions were inorganic for the individuals creating them. The difference between the individual as a person and what is accidental to him, is not a conceptual difference but an historical fact. This distinction has a different significance at different times -- e.g. the estate as something accidental to the individual in the eighteenth century, the family more or less too. It is not a distinction that we have to make for each age, but one which each age makes itself from among the different elements which it finds in existence, and indeed not according to any theory, but compelled by material collisions in life.
What appears accidental to the later age as opposed to the earlier -- and this applies also to the elements handed down by an earlier age -- is a form of intercourse which corresponded to a definite stage of development of the productive forces. The relation of the productive forces to the form of intercourse is the relation of the form of intercourse to the occupation or activity of the individuals. (The fundamental form of this activity is, of course, material, on which depend all other forms-mental, political, religious, etc. The various shaping of material life is, of course, in every case dependent on the needs which are already developed, and the production, as well as the satisfaction, of these needs is an historical process, which is not found in the case of a sheep or a dog (Stirner's refractory principal argument adversus hominem ), although sheep and dogs in their present form certainly, but malgré eux, are products of an historical process.) The conditions under which individuals have intercourse with each other, so long as the above-mentioned contradiction is absent, are conditions appertaining to their individuality, in no way external to them; conditions under which these definite individuals, living under definite relationships, can alone produce their material life and what is connected with it, are thus the conditions of their self-activity and are produced by this self-activity. The definite condition under which they produce, thus corresponds, as long as the contradiction has not yet appeared, to the reality of their conditioned nature, their one-sided existence, the one-sidedness of which only becomes evident when the contradiction enters on the scene and thus exists for the later individuals. Then this condition appears as an accidental fetter, and the consciousness that it is a fetter is imputed to the earlier age as well.
These various conditions, which appear first as conditions of self-activity, later as fetters upon it, form in the whole evolution of history a coherent series of forms of intercourse, the coherence of which consists in this: in the place of an earlier form of intercourse, which has become a fetter, a new one is put, corresponding to the more developed productive forces and, hence, to the advanced mode of the self-activity of individuals-a form which in its turn becomes a fetter and is then replaced by another.
