The theory of resistance here elaborated is based on considerations current since the 18th century and concern the proof of reality of the external world. However, what is ignored in the course of these proofs are the social, psychological, and in particular the logical aspects of resistance. The idea of a theory of resistance is inspired by tendencies in the philosophy of technology, as well as other current philosophical and scientific lines of thought that obscure their metaphysical underpinnings, advocating a (...) position of complete achievability of human and natural relations. The theory of resistance seeks to show that resistance is a reflexive term that concerns relations, not objects or those relations that can be expressed in qualities and quantities. Furthermore, this concept has a positioning role, important in epistemological, as well as ethical and anthropological sense. Resistance is a central, although not the sole characteristic of reality. As an ethical category, it is articulated, for example, in the idea of dignity if understood as hostility to mere typologization and subjection to calcu?lation. The theory of resistance does not advocate some existing reality, but limits the domain of validity of constructivist and narrativist theories. (shrink)
