This chapter considers both conceptual reasons and empirical evidence in favour of the dualistic model of the human visual system applied to the vision of objects. It examines the contribution of the visual system to a restricted class of human actions — reaching, grasping and manipulating objects in one's vicinity — and argues that one and the same visual stimulus can undergo perceptual processing or motor processing. It characterizes the major differences between these two kinds of processing of visual inputs, called ‘semantic’ and ‘pragmatic’ processing. The chapter makes the bold claim that a new kind of non-conceptual content has been discovered by the cognitive neuroscientific study of the visual system, i.e. visuomotor content.
