- That's all I mean by "using the Turing Test"; using only behavioral

- Whoops. I meant:
-
- Behavior is the causal relationship between a history of
- effects of the environment on the system, and the actions taken
- by the system.

-
- Yes. As I said, behavior is a causal relationship between inputs and
- outputs, it is *not* simply a sequence of actions. While it may be
- possible to classify actions as "unintelligent", and it may be
- possible for an intelligent entity to produce an unintelligent action,
- I don't believe it is possible for an intelligent entity to have an
- unintelligent behavior (or vice-versa).
-
- >And if not, what has been ruled out?
-
- You can rule out the possibility that the entity completely ignores
- what is said to it (as a phonograph does). You can rule out the
- possibility that the entity simply repeats what is said to it (as
- a parrot does). You can rule out the possibility that the output
- is simply a syntactic rearrangement of the inputs (as Eliza does).

-
- Agreed. But the judging intelligence (and other mental properties)
- based on behavioral evidence is about as justified as any fallible
- test can be.
