Stalnaker on sensuous knowledge

Robert Stalnaker has recently argued that a pair of natural thoughts are incompatible. One of them is the view that items of non-indexical factual knowledge rule out possibilities. The other is the view that knowing what sensuous experience is like involves non-indexical knowledge of its phenomenal character. I argue against Stalnaker’s take on things, elucidating along the way how our knowledge of what experience is like fits together with the natural idea that items of non-indexical factual knowledge rule out possibilities. I am grateful to Nel Block, Dque Chalmers, Benj Hellie, Mike Martin, Susanna Siejel, Robert Stalnaker and especially Majo Spencer for help with this work.
