 In the Treatise, Condillac was no longer willing to declare that objects can be known to be either extended or colourless. He simply claimed that its experiences would lead his “statue” to first conceive of colours as modifications of its own being, then to conceive them as modifications of its extended sense organs, and finally to conceive them as modifications of external objects (Treatise III.3). But this was not to answer the metaphysical problem but rather to ignore it. If colours are in fact extended, as the Treatise continued to insist, yet the mind ultimately only knows its own sensations, however variously they might be transformed by cognitive processing, then we can only come to be in a position to attribute colours to external objects if we first experience those colours, which suggests that they must modify our being.
