The argument seems wrong to me intuitively, but I'm hard-put to argue against it because the terms are so unclearly defined ... for instance I don't really know what you mean by a "visual scene" ...
I can understand that to create a form of this argument worthy of being carefully debated, would be a lot more work than writing this summary email you've given. So, I agree with your judgment not to try to extensively debate the argument in its current sketchily presented form. If you do choose to present it carefully at some point, I encourage you to begin by carefully defining all the terms involved ... otherwise it's really not possible to counter-argue in a useful way ... thx ben g On Sat, Oct 4, 2008 at 12:31 AM, Colin Hales <[EMAIL PROTECTED]>wrote: > Hi Mike, > I can give the highly abridged flow of the argument: > > !)
