The conclusion of Franck Fishbach's La Production des Hommes: Marx Avec Spinoza ends with a discussion of Heidegger's understanding of production in contrast to its focus on the intersection of Marx and Spinoza. A Fischbach argues the contrast could not be more clear, whereas Marx and Spinoza posited a thought of production that broke with idealism, with much of philosophy, Heidegger saw production as the basis and culmination of metaphysics. Our conceptions of substance, being, and actuality all stem from humanity's productive comportment and this understanding of being culminates in the idea of a world in which what exists exists to be manipulated, produced, transformed, exists as an object for a subject. Production is the metaphysics of subjectivity.
