Abstract
In the era of “high tech capitalism”, an era involving a progressive automation of production processes, we need a reading of Marx that reconnects his early works with those of his maturity and with some Engels’ key-texts, including the Dialectics of Nature. Today this reading is indispensable in order to think the current historical phase in its complexity. Against the apologists of a post-human robotics, it is necessary to build a new form of humanism, related to a practical dialectics that is the only true alternative to metaphysics. Only in this way, in the technological era, we will be able to understand society and nature not as abstractly splitted, but in their differentiated relationship, in view of a suitable form of praxis.
