“it is a system of light before being a figure of stone”

“a visual assemblage and a luminous environment” (Deleuze, Foucault: 32)

“A system of light and a system of language are not the same form, and do not have the same formation.”

“expressing the ‘effects’ of analysis, not in a causal way but through the use of optics and colour: the red on red of the tortured inmates contrasts with the grey on grey of prison.” (24)

“a form that haunted the whole of Foucault’s work: the form of the visible as opposed to the form of whatever can be articulated.” (32)
