Extended vision

Vision constitutes an interesting domain, or range of domains, for debate over the extended mind thesis: the idea that minds extend physically beyond the boundaries of the body. In part this is because vision (and visual experience more particularly) are sometimes presented as a kind of line in the sand for what we might call externalist creep about the mind: once all reasonable concessions have been made to externalists about the mind, visual experience marks a line beyond which lies a safe haven for individualists. This chapter puts a little more pressure on such a view of visual experience, and offers a more constructive, positive argument in defence of the idea of extended vision.
