RE: Re: Why AI is impossible
I used the term *omniscience* in a rather general way, as a substitute for the term *universal* though it should be said that the purpose was to serve as adjective to the term *computational* rather than the other way around, as might be expected when the phrase is given in the form of *computational omniscience*. I like to play with language, and English has a rather free form. Omniscience has a sense of universality to it, and it is not solely connected to deity; there is also notion of realm, and mathematics is such. Hence, omniscience over computation (computational omniscience) represents not so much all knowing as all computable, and remember, all that is computable is so computable upon Turing machine as it might be anywhere else. The Turing machine, simply by its construction, computes in this universal fashion, and no other means of computing provides answers beyond those provided by Turing machine. Hence, the Turing machine is not only universally competent as a computer, it also is computationally omniscient. wrb From: everything-list@googlegroups.com [mailto:everything-list@googlegroups.com] On Behalf Of Roger Sent: Thursday, August 16, 2012 8:12 AM To: everything-list Subject: Re: Re: Why AI is impossible Hi Bruno Marchal The Bible teaches that God spends much of his time looking into men's hearts to see if love or evil rests there.

Re: Re: Why AI is impossible
Hi Bruno Marchal This is hard to put into words. No offense, and I may be wrong, but you seem to speak of the world and mind as objects. But like a coin, I believe they have a flip side, the world and mind as we live them, not as objects but as subjects. Entirely different worlds. It is as if you talk about swimming in the water without actually diving in. Or treating a meal as that which is on the menu, but not actually eating it.
