Abstract: | This paper defends a non-reductive realist view of the sensible qualities—roughly, the view that the sensible qualities are (i) really instantiated by the external objects of perception, and (ii) not reducible to response-independent physical properties or response-dependent relational properties. I begin by clarifying and motivating the non-reductive realist view. I then consider some familiar difficulties for the view. Addressing these difficulties leads to the development and defence of a general theory, inspired by Russellian Monist theories of consciousness, of how the sensible qualities (especially the so-called ‘secondary qualities’) relate to physical reality. I conclude by showing how this theory, which I call ‘Secondary Quality Russellian Monism’, resolves the most significant difficulties for the non-reductive realist view of the sensible qualities. |
