André Leroi-Gourhan

“André Leroi-Gourhan (25 August 1911 – 19 February 1986) was a French archaeologist, paleontologist, paleoanthropologist, and anthropologist with an interest in technology and aesthetics and a penchant for philosophical reflection.

Leroi-Gourhan completed his doctorate on the archaeology of the North Pacific under the supervision of Marcel Mauss.”

“In L’Homme et la matière [Man and Matter] (1943), Leroi-Gourhan proposes the concept of technical tendencies, that is, universal technical dynamics that operate independently of the ethnic groupings which are nevertheless the only forms through which these tendencies are concretised. The concretisation of the technical tendency in a particular ethnicity he calls a technical fact.

In Milieu et techniques [Environment and Techniques] (1945), Leroi-Gourhan develops this into a general theory of the relation between the technical (as universal tendency) and the ethnic (as specific, differentiated concretisation). The human group, according to Leroi-Gourhan, behaves as though it were a living organism, assimilating its exterior milieu via “a curtain of objects”, which he also calls an “interposed membrane” and an “artificial envelope”, that is, technology. The milieu of the organism is divisible into the exterior milieu (geography, climate, animals and vegetation) and the interior milieu (the shared past of the group, thus “culture”, etc.). This division enables a clarification of the concept of technical tendency. A tendency, according to Leroi-Gourhan, is a movement, within the interior milieu, that gains progressive foothold in the exterior milieu. “

“The French philosopher Jacques Derrida discusses Leroi-Gourhan in Of Grammatology (Baltimore & London: The Johns Hopkins University Press, 1997, corrected edition), in particular the concepts of “exteriorisation”, “program”, and “liberation of memory.” This discussion was particularly important in the formulation of Derrida’s neologism, différance.

Leroi-Gourhan is frequently cited in the two volume collaboration by French philosopher Gilles Deleuze and psychiatrist Félix Guattari entitled Capitalism and Schizophrenia. The hand/tool and face/vocalization couplings of Leroi-Gourhan play an important role in the development of Deleuze and Guattari’s concepts of becoming and deterritorialisation.

The French philosopher Bernard Stiegler gives an extensive reading of Leroi-Gourhan in Technics and Time, 1: The Fault of Epimetheus (Stanford: Stanford University Press, 1998). “
