Abstract
What is implicit in a typically human perception of a material object? First, perceivability is a contingent property of its bearer, relative to perceiver and conditions. Typically, human perception is special in involving the use of concepts and an awareness of object‐structures. When we visually recognize a material object, an almost limitless array of properties and procedures are by implication condensed into an instant: one entertains multiple beliefs, and posits at a distance, multiple properties. Then the experiential integration of the almost limitless visual evidence of a material object is dubbed ‘constituting the material object out of experience’. Central concepts in doing so are those of side, outside, surface, interior, and part. The most important of these experiential syntheses is the spatial, whose unit is the 3D‐seeing of object‐sides, a concept that depends upon those of 2D/3D and 2D/2D seeing. Two vitally important elements in this procedure are, first, the work of the understanding, second, an awareness of the objective physical situation of perceiver and object.
