This article explores the theoretical intersections and divergences between Bernard Stiegler and Catherine Malabou, two prominent figures shaped by the deconstructive legacy of Jacques Der-rida, but whose mutual engagement remains limited. The article seeks to establish a hermeneu-tical framework to address this gap: reading Malabou and Stiegler as “transformation masks” of deconstruction. §1 analyzes Derrida’s concept of trace and its implications for understanding life, death, and exteriority; §2 delves into Stiegler’s epiphylogenesis, highlighting the role of technicity as a co-evolutionary force shaping human individuation; §3 discusses Malabou’s notion of plas-ticity, its Hegelian roots, and its extension into neurosciences and epigenetics. The article pro-poses a “pharmacology of plasticity” as a conceptual bridge between their frameworks, §4. This approach addresses the ambivalence of plasticity as both a creative and a disruptive force. It argues that integrating technicity and plasticity offers new insights into the political stakes of sub-jectivity in a technologically mediated world. By synthesizing Derrida’s différance, Stiegler’s gram-matization, and Malabou’s morphogenesis, the paper advances a nuanced understanding of the dynamic interplay between life, form, and technology.
