My post was about using non-commutative geometry to describe space-time, and, perforce, all the physical systems in space-time, of which brains are one example. <BR/><BR/>The claim that mental states have no spatial extent is a separate premise, endorsed by McGinn. I sought to re-conceptualise the brain, using non-commutative geometry, in a way which would make it easier to reconcile the nature of mental states with the nature of the brain.Gordon McCabehttps://www.blogger.com/profile/09151162643523937086noreply@blogger.comtag:blogger.com,1999:blog-37936507.post-27064259551366655372007-04-20T14:13:00.000+01:002007-04-20T14:13:00.000+01:00Clearly, but your post was about using non-commuta...Clearly, but your post was about using non-commutative geometry to describe mental states, not space-time. That would lead to the claim that mental states do not have spacial extent, but that's begging the question in light of point (4).<BR/><BR/>A better analogy would be the claim that my computer can't fit on my desk because I can run Google Earth on it and clearly the Earth is bigger than my desk.Susan's Husbandhttps://www.blogger.com/profile/02862667802025231163noreply@blogger.comtag:blogger.com,1999:blog-37936507.post-46467060970393428832007-04-19T23:36:00.000+01:002007-04-19T23:36:00.000+01:00If a map of the world requires a Mercator projecti...If a map of the world requires a Mercator projection to accurately represent distances, then it suggests that the world is round rather than flat. Similarly, if a representation of the structure of space-time requires non-commutative geometry to be accurate at small as well as large scales, then it suggests that space-time is not a manifold of points.Gordon McCabehttps://www.blogger.com/profile/09151162643523937086noreply@blogger.comtag:blogger.com,1999:blog-37936507.post-16722250343773942522007-04-19T21:47:00.000+01:002007-04-19T21:47:00.000+01:00— Non-commutative geometry suggests that the...—<EM> Non-commutative geometry suggests that the spatial extension of any physical system, including the brain, is an illusion. </EM>—<BR/><BR/>Nonsense, you're confusing the map for the territory.Susan's Husbandhttps://www.blogger.com/profile/02862667802025231163noreply@blogger.com
