Herbert Marcuse was one of the most influential political philosophers in the 20th century. After his death, his popularity started decreasing and the philosopher somewhat sank into oblivion. This dissertation intends to investigate the Marcusean contribution to the subject of technics, so imbricated on his political philosophy, and demonstrate that it deserves reappraisal. We shall analyse the theoretical context of Marcuse’s work and put opposing stances, both technophobe and technophile, up for debate. The intent is to not only present the (...) topics that organized this discussion back in its day, but also to set Marcuse apart from such hardline approaches. We shall then elucidate the Marcusean criticism of the capitalist technological system of advanced industrial societies and present the fundamental lines of its new historical project, supported by a qualitative change made possible by the ambivalence of technics. Since, in Marcuse’s view, technics configure the basis for the organisation of the status quo, and also the basis which might modify it if duly reoriented, the ambivalent character which the philosopher identifies in technics becomes the nuclear idea in his thesis; it is the very foundation upon which he builds his philosophy of technics. The marcusean thoughtshall then be exposed to critique: we shall examine the most relevant objections raised against it, but also its most fruitful ideas. Through the contributions of Gorz and, more specifically, of Feenberg, we intend to confirm the relevance of Marcuse’s thought in the context of the hodiern technological reality. (shrink)
