Seeing and demonstration (Perception)

We see things. We also perceptually demonstrate things. There seems to be s ome sort of ling between these two phenomena. Indeed, in the standard case, the former is accompanied by a capacity for the latter. One sees a dog and can, on the basis of one's perceptual capacities, think thoughts of the fo rm 'That is F.' But how strong is that link? Does seeing a thing (in the su ccess sense of seeing) inevitably bring with it the capacity for perceptual ly demonstrating it? In what follows, we argue for a negative answer to thi s question. In so doing, we hope to shed some light on the phenomenon of pe rceptual demonstration. After presenting the main argument in section one, we go in section two to consider a series of objections and replies.
