| Summary: | Molyneux's Question (MQ) concerns whether a newly sighted man would recognize/distinguish a sphere and a cube by vision, assuming that he could previously do this by touch. We argue that MQ splits into questions about (a) shared representations of space in different perceptual systems, and about (b) shared ways of constructing higher-dimensional spatiotemporal features from information about lower-dimensional ones, most of the technical difficulty centring on (b). So understood, MQ resists any monolithic answer: everything depends on the constraints faced by particular perceptual systems in extracting features of higher dimensionality from those of lower dimentionality.
