The aim of this article is to consider biobanks through the conceptual tools of French Thought and twentieth-century French philosophy of technology. Firstly, two pairs of authors and their respective conceptions of the relationship between technics and memory are considered: on the one hand, Jacques Derrida and Bernard Stiegler, who thought of memory and technics on the model of writing; on the other hand, Henri Bergson and André Leroi-Gourhan, who thought of memory as linked to biological life, and of technics (...) as an exteriorization of life. On the basis of this discussion, a philosophical analysis of biobanks is then provided, understanding them as exteriorized memories of life, and some conceptual problems raised by biobanks are addressed: the question of exteriorization and its relation with the organic and the inorganic matter; the relation between the living and the environment; the mode of existence of biological data; and the distinction between natural and artificial memory.
