His mother was Yvette Lemat (1931–2025), a French-Swiss native of the Canton of Vaud, a German teacher, and an honorary deputy headmistress of the Lycée Condorcet (Paris). Franck Fischbach completed his secondary education at that lycée, as well as two years of preparatory classes (including the khâgne in the philosophy class of Jean-Pierre Osier, a student of Louis Althusser and translator of Ludwig Feuerbach and Thomas Hodgskin.
He completed a habilitation to direct research in philosophy in 2002. The habilitation was sponsored by Jean-François Kervégan, also at Paris 1, and investigated the formation of the modern ontology of activity spanning Fichte to Marx. It was titled L'Être et l'Acte.
Fischbach’s work encompasses two fields: first, the history of modern and contemporary German philosophy (ranging from Fichte to Heidegger and the Frankfurt School’s Critical Theory, including Hegel, the Young Hegelians, and Marx; and second, social philosophy He has helped develop this latter field in France by defining it as a critical approach to social forms of life, one informed by insights from the social sciences and capable of addressing issues such as alienation or recognition. It is within this theoretical framework that Fischbach has philosophically addressed the question of labor. He has proposed understanding labor as an activity that cannot be reduced merely to production (poiésis) but is instead characterized by a significant practical (or "praxic") dimension, evidenced by the stakes of self-realization or collective liberation pursued by those involved in the work process. If social labor consists of a set of activities through which a society regulates its interactions with nature and ensures its own reproduction, then the subjection of labor activities to the productivist imperative of accumulation under capitalist social relations leads to a crisis of social reproduction, a crisis that, according to Fischbach, constitutes a significant dimension of contemporary ecological crises.
↑See his book: Philosophies de Marx, Vrin: 2015. The referenced article by Jérôme Skalski talks about the anthology of translations of the Young Hegelians (Gallimard, 2023) which he edited and also refers to his book Science de la logique.
↑See his works: Manifeste pour une philosophie sociale, La Découverte, 2009; Le sens du social, Lux Éditeur: 2015; and Faire ensemble, Le Seuil: 2024. The referenced article from Libération talks about his translations of Hegel, Schelling, Marx, and Honneth. Maggiori, the writer, also talks about Fischbach's book Le sens du social (Lux, 2015) and what's needed toward a new sense of social life in a free democratic society.
↑The article by Louis Pinto talks about his book La Privation de monde where he attempts to combine Heidegger and Marx into a theory of labor based on how it shapes the social sense of the individual and how its disintegration into overemphasis on production leads to world deprivation.
↑See his works: La production des hommes, 2005, 2nd ed. 2014 Après la production. Travail, nature et capital, 2019. The referenced article from Pierre Chaillan goes into Fischbach's book Faire ensemble (the title meaning "working together").
↑Pour la Théorie critique. Raison, nature et société, Vrin: 2024. Again, the referenced article talks about Faire ensemble: Reconstruction sociale et sortie du capitalisme. Like his other books, it discusses the social disintegration and overproduction, but here is the theory to reconstruction after capitalism and to address the ecological crisis.
