Let us now look more closely at the objectification, at the production of the worker; and in it at the estrangement, the loss of the object, of his product.

The worker can create nothing without nature, without the sensuous external world. It is the material on which his labor is realized, in which it is active, from which, and by means of which it produces.

But just as nature provides labor with [the] means of life in the sense that labor cannot live without objects on which to operate, on the other hand, it also provides the means of life in the more restricted sense, i.e., the means for the physical subsistence of the worker himself.

Thus the more the worker by his labor appropriates the external world, sensuous nature, the more he deprives himself of the means of life in two respects: first, in that the sensuous external world more and more ceases to be an object belonging to his labor–to be his labor’s means of life; and, second, in that it more and more ceases to be a means of life in the immediate sense, means for the physical subsistence of the worker.

In both respects, therefore, the worker becomes a servant of his object, first, in that he receives an object of labor, i.e., in that he receives work, and, secondly, in that he receives means of subsistence. This enables him to exist, first as a worker; and second, as a physical subject. The height of this servitude is that it is only as a worker that he can maintain himself as a physical subject and that it is only as a physical subject that he is a worker.

(According to the economic laws the estrangement of the worker in his object is expressed thus: the more the worker produces, the less he has to consume; the more values he creates, the more valueless, the more unworthy he becomes; the better formed his product, the more deformed becomes the worker; the more civilized his object, the more barbarous becomes the worker; the more powerful labor becomes, the more powerless becomes the worker; the more ingenious labor becomes, the less ingenious becomes the worker and the more he becomes nature’s slave.)

Political economy conceals the estrangement inherent in the nature of labor by not considering the direct relationship between the worker (labor) and production. It is true that labor produces for the rich wonderful things–but for the worker it produces privation. It produces palaces–but for the worker, hovels. It produces beauty–but for the worker, deformity. It replaces labor by machines, but it throws one section of the workers back into barbarous types of labor and it turns the other section into a machine. It produces intelligence–but for the worker, stupidity, cretinism.

The direct relationship of labor to its products is the relationship of the worker to the objects of his production. The relationship of the man of means to the objects of production and to production itself is only a consequence of this first relationship–and confirms it. We shall consider this other aspect later. When we ask, then, what is the essential relationship of labor we are asking about the relationship of the worker to production.

Till now we have been considering the estrangement, the alienation of the worker only in one of its aspects , i.e., the worker’s relationship to the products of his labor. But the estrangement is manifested not only in the result but in the act of production, within the producing activity, itself. How could the worker come to face the product of his activity as a stranger, were it not that in the very act of production he was estranging himself from himself? The product is after all but the summary of the activity, of production. If then the product of labor is alienation, production itself must be active alienation, the alienation of activity, the activity of alienation. In the estrangement of the object of labor is merely summarized the estrangement, the alienation, in the activity of labor itself.

What, then, constitutes the alienation of labor?

First, the fact that labor is external to the worker, i.e., it does not belong to his intrinsic nature; that in his work, therefore, he does not affirm himself but denies himself, does not feel content but unhappy, does not develop freely his physical and mental energy but mortifies his body and ruins his mind. The worker therefore only feels himself outside his work, and in his work feels outside himself. He feels at home when he is not working, and when he is working he does not feel at home. His labor is therefore not voluntary, but coerced; it is forced labor. It is therefore not the satisfaction of a need; it is merely a means to satisfy needs external to it. Its alien character emerges clearly in the fact that as soon as no physical or other compulsion exists, labor is shunned like the plague. External labor, labor in which man alienates himself, is a labor of self-sacrifice, of mortification. Lastly, the external character of labor for the worker appears in the fact that it is not his own, but someone else’s, that it does not belong to him, that in it he belongs, not to himself, but to another. Just as in religion the spontaneous activity of the human imagination, of the human brain and the human heart, operates on the individual independently of him–that is, operates as an alien, divine or diabolical activity–so is the worker’s activity not his spontaneous activity. It belongs to another; it is the loss of his self.

As a result, therefore, man (the worker) only feels himself freely active in his animal functions–eating, drinking, procreating, or at most in his dwelling and in dressing-up, etc.; and in his human functions he no longer feels himself to be anything but an animal. What is animal becomes human and what is human becomes animal.

Certainly eating, drinking, procreating, etc., are also genuinely human functions. But taken abstractly, separated from the sphere of all other human activity and turned into sole and ultimate ends, they are animal functions.

We have considered the act of estranging practical human activity, labor, in two of its aspects. (1) The relation of the worker to the product of labor as an alien object exercising power over him. This relation is at the same time the relation to the sensuous external world, to the objects of nature, as an alien world inimically opposed to him. (2) The relation of labor to the act of production within the labor process. This relation is the relation of the worker to his own activity as an alien activity not belonging to him; it is activity as suffering, strength as weakness, begetting as emasculating, the worker’s own physical and mental energy, his personal life–for what is life but activity?–as an activity which is turned against him, independent of him and not belonging to him. Here we have self-estrangement, as previously we had the estrangement of the thing.
