This chapter explains Descartes confusion on sensations, size, shape, position, and motion. Descartes in detail explains that we perceive particular figures or actual bodies affecting our senses much more distinctly than their colours. Descartes construe the perception of position, distance, size, and shape as involving strong intellectual elements and he holds that they differ in this fundamental respect from ordinary perceptions of color, sound, heat and cold, taste, and the like, which are said to consist just in having “sensations” that (...) “arise from the mind-body union.” This position leaves room for uncertainty about what he means when he speaks elsewhere of the near-uselessness of sense perceptions in informing us of particular qualities of bodies, in so far as it opens the possibility of a quite restricted understanding of “sense perception” in these contexts.
