 Though Condillac’s official reply to the charge of materialism, as expressed in the letter to Lignac, is something of a disappointment, scholars have occasionally read the Treatise as taking some steps towards a more radical way of dealing with the problem. Recall that in that work Condillac advanced the view that even though colours are in fact extended and bounded, it is not intuitively evident that they are. We need to learn to see their shapes. Interestingly, what teaches us to see these shapes are tactile sensations of solidity and observations of the appearance and disappearance of colours consequent upon moving our hands before our eyes. Since neither sensations of solidity nor the tactile sensations that accompany hand motions are patently extensive in character, and colours themselves might as well not be so far as the early learner is concerned, some scholars have suggested that the Condillac of the Treatise meant to claim that our perceptions of space are constructed from raw data that, as they are at first experienced by the mind, are in no way spatial. Insofar as the Treatise does move towards this more radical view, it can be seen as a precursor of such 19th century Berkeleyan theories of vision as those of Steinbuch, Mill, Helmholtz, and Wundt. However, those later theories invoked notions of local signs (sensations specific to which nerve is being stimulated) and made explicit appeals to kinaesthetic sensations that are simply absent from Condillac’s work. Lacking those notions, Condillac claimed that an awareness of space cannot be generated from aspatial sensations, and he represented his statue, not as constructing space, but as discovering the spatial features that were already present in its sensations from the first. Viewing him as a precursor of 19th century Berkeleyanism risks overlooking this fact and, as a consequence, misrepresenting his thought.
