no. that isn't possible for physical properties either, and in any case has nothing to do with determinism > If you possessed this algorithm, I could present you with a large cube > of metal, silicon, and flashing lights, you could apply your algorithm > to determine for certain whether any form of artificial intelligence > was instantiated by the cube? > > No matter how obfuscated, encrypted, or abstract the representation > used to instantiate the AI? > > This would be in contradiction to Hilary Putnam's work: > > "Putnam's proposal, and its historical importance, was analyzed in > detail in Piccinini forthcoming b.

In what sense does it exist, if not physically? I assume your list of mass, charge, etc, were intended to be.

It's something you can have, but not choose to have. It is not, in other words an achievement; one wuuld be no more responsible for ones rationality or intelligence than eye-colour > For any given input, a deterministic system can only react in one way. > > If you expose a deterministic system to a set of inputs that represent > a particular environment, the system will react in the one and only > way it can to that set of inputs. > > Knowledge is just the internal state of the deterministic system. > > This is true of a human.

You haven't shown they are equally (un)intelligent. the behaviour of a dropped rock and a dropped feather may be equally indeterministic, but it is not the same > And, as I pointed out in the original post, probabilistic systems are no > better. better at what? the only thing determinism is incompatible with is free choice. in order to argue that determinism is incompatible with intelligence, you have to take intelligence to mean something like freely chosen intelligence > Intelligence is an arbitrary criterion based only on how things "seem" > to you, and which has no other basis in how things are. not established. That something has a relatively wide and complex repertoire of responses to stimuli is an objective fact. (That it has "memory", or the ability to modify its responses according to its whole history and not just the present stimulus is as well) > So, that is what I mean by: > > "The word 'intelligence' doesn't refer to anything except the > experiential requirements that the universe places on you as a > consequence of its causal structure." nothing above explains the "experiential requirements" clause -- You received this message because you are subscribed to the Google Groups "Everything List" group.
