jim; //...computing gives us a sort of hint -- information can easily be stored in a physical way. No reason to suppose that the same doesn't apply, albeit in much more complexity, in our own brains.//
True to some extent, but the computer can only reproduce what it already 'knows', just like we can see things which we once knew but no longer exist via our memory, but we can also imagine things which do not, nor have never existed; if I ask you to visualise say, an apple nailed to a dartboard by a 6 inch nail, you can see that in your 'minds eye' but it is beyond your experience. So I'm wondering how that image can exist in the physical domain, and if it doesn't, it must exist outside of it, wouldn't you say?
(To be sure, I have just typed it into Google images, and it isn't there. :-) )
