Deleuze & Guattari’s Souriau reference

Hat-tip to Alex Galloway:

“In 1939 Etienne Souriau published L’instauration philosophique (Paris: Alcan, 1939). Aware of creative activity in philosophy, he invoked a kind of plane of instituting as the ground of his creation, or ‘philosopheme,’ animated by dynamisms.”

(pp. 62-63)” (Deleuze and Guattari, What Is Philosophy?, 220n6).
