ABSTRACT. Marx depicts the worker under capitalism as suffering from four types of alienated labour: i) from the product, which as soon as it is created is taken away from its producer; ii) in productive activity (work) which is experienced as a torment; iii) from species-being, for humans produce blindly and not in accordance with their truly human powers; iv) from other human beings, where the relation of exchange replaces mutual need. Revolution and epoch change is understood as the consequence of an economic structure no longer being able to continue to develop the forces of production.
