Le mouvement d’extériorisation. Husserl, Derrida, Stiegler

The third appendix to § 9a of Husserl’s The Crisis of the European Sciences, baptized by Eugen Fink “The Origin of Geometry”, presents us with a prototype of an “exteriorization movement” (linguistic-scriptural) that inaugurates, in the context of French philosophy, an important history of effects. Beginning with the Husserlian text, the essay focuses its attention on the readings and perspectives of thought of Jacques Derrida (logic of supplement, différance) and Bernard Stiegler (reciprocal invention of anthropos and techne, epiphylogenesis), finally proposing a further way, hinging on the principle of the “return effect”, of interpreting and putting to work the question of the movement of technical and “techno-logical” exteriorization.
