The concept of “Machination” (Machenschaft) occupies a central place in Heidegger’s work during the period between 1936 and 1940. In his analysis of the essence of the Modern Age, the Marxist-oriented czech philosopher Karel Kosík appropriates important conceptual elements from this stage of Heidegger’s thought. In particular, he employs analogous notions to “Machination”, as “Manipulability System”. We highlight the similarities and points of friction in the description of the essence of the Modern Age in both thinkers, as well as their respective proposals to limit technical primacy and calculative thinking and political resonances derived from their analysis.
