Intelligence is not something you can "detect" by observing neuronal activity, it is an emergent property of extremely complex systems, it derives from their structure, it is manifested in their behaviour, and it comes on a sliding scale. Some cats are more intelligent than others. Cats are more intelligent than slugs, and less intelligent than most humans. (Slug lovers, no flames please!) Do not make the mistake of defining intelligence to be "What humans do". Firstly, it begs the question. Secondly, it degenerates rapidly into "What X believes humans do", where X is you, me, or some other know-all who probably has an extremely shallow understanding of *what* it is that humans do, let alone *how*. People who, for whatever reason, insist on equating intelligence with "What (and how) humans do" should at least have the decency to speak about "human intelligence", leaving the unqualified word free to describe a wider range of phenomena. Have you considered the possibility that it may not be possible for a system to be intelligent enough to understand its own workings? Certainly, if you insist on knowing *how* a system works before you ascribe intelligence to it, then you cannot claim yourself to be intelligent. How does your memory work? How do you recognise objects in the real world so easily? How does your ability to make abstractions arise? You do not know the answers to these questions. Understanding how complex systems work is *very* difficult. If you know *how* a system works, then you can conclude that you're probably much more intelligent than it is, and hence that it's not very intelligent. We must content ourselves with behavioural definitions of intelligence, such as the Turing Test, at least until such time as we have a far more profound understanding of how intelligence arises. Claims about a given system passing the Turing Test, while clearly not being intelligent, are specious unless it is clear that such a system is (in principle) constructible, and would in fact pass the test. Remember that we currently do not know how to construct *any* system that passes such a test, except by unskilled labour. If and when such a system is achieved or encountered, the chances are that those not blinded by prejudice will admit its intelligence, but few if any of us will begin to understand how it works. -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= David Kinny Australian Artificial Intelligence Institute dnk@aaii.oz.AU 1 Grattan Street Phone: +61 3 663 7922 CARLTON, VICTORIA 3053, AUSTRALIA
