 The most developed proposal has come from Christopher Peacocke who has proposed a radically externalist conception of nonconceptual content aimed explicitly at explaining the nonconceptual content of perceptual states (Peacocke 1992). Peacocke suggests that a given perceptual content should be specified in terms of the ways of filling out the space around the perceiver that are consistent with the content’s being correct. For each minimally discriminable point within the perceiver’s perceptual field (where these are identified relative to an origin and axes centered in the perceiver’s body) we need to start by specifying whether it is occupied by a surface and, if so, what the orientation, solidity, hue, brightness and saturation of that surface are. This specification gives us the way the perceiver represents the environment. The content of that representation is given by all the ways of filling out the space around the perceiver in which the minimally discriminable points have the appropriate values. The representation is correct just if the space around the perceiver is occupied in one of those ways. Peacocke calls this type of nonconceptual content positioned scenario content.
