Molyneux's Question Within and Across the Senses

This chapter explores how our understanding of Molyneux’s question, and of the possibility of an experimental resolution to it, should be affected by recognizing the complexity that is involved in reidentifying shapes and other spatial properties across differing sensory manifestations of them. I will argue that while philosophers today usually treat the question as concerning ‘the relations between perceptions of shape in different sensory modalities’ (Campbell 1995, 301), in fact this is only part of the question’s real interest, and that the answer to the question also turns on how shape is perceived within each of sight and touch individually.
