Abstract
The lasting cultural attitude distrusting image, and especially certains forms of visualisation, shows the functionment of cultural norms of the possible representation of the private, the valuable, the sacred. In the level of the cultural practice of visualisation, this ethical and political impossibility manifests itself as a ban, eventually as a censorship destined to eliminate the "inaproppriate" images.
In the level of the theoretical thought, it is mostly treated as a philosophical reflection of the representable, the visible, the visibility. This reflection partly founds the work of two french thinkers: Michel Foucault and Georges Didi-Huberman.
The paper analyses their approches the representation and the representable : why and how does the concept of visibility give rise to a discussion about limits of representable, a discussion with political connotation?
