Perception permits us to think and know about what we perceive. Upon seeing an object for the first time, you are in a position to form thoughts about it that you would express with sentences like ‘that is tall’ or ‘that is red’.
Whatever role perceiving objects plays in anchoring this variety of thought about objects, we can ask: does property perception play a parallel role for our capacity to form perception-based thoughts about sensible properties, and is this the case for all or only some sensible properties?
If more is required of property perception—and many assume that it is—then this imposes substantive constraints on the right account of property perception. Yet if more is required, what is it about properties and, relatedly, perception-based thought about properties that imposes these demands?
