Ce texte prononcé par Gilbert Simondon (1924-1989) à la Sorbonne en 1965-1966 développe une théorie de l'image en en faisant la genèse. Il constitue une réflexion sur la façon dont l'image se forme et devient une fonction vitale lorsqu'elle sert l'invention et les techniques.--[Memento].
The image and imagination have always seemed fundamental and overdetermining for philosophers, but also enigmatic, not easily placed in relation to reasoning, sensation, memory etc. For Simondon the image belongs to the living, and in fact is a kind of living organism itself, almost a parasite, growing, mutating, evolving and branching out. Neither inside nor outside, it brings together extremes by actively formalizing, recruiting and amplifying. Passing through several cycles, it enriches the body as it interfaces with the milieu, becoming a symbol and culminating in a creative prosthesis that can be detached and proliferate.
