Turing's Test Are human beings Turing machines? More exactly Can they be simulated by such discrete state machines? Turing's great advance. Taking an intuitively, hard to answer question and making it precise So that we can answer it. Objections 1. mathematical (Only sketched). It fails 2 Theological Different religions give different views. So unfair to adopt Christian view In truth, Turing doesn't take this seriously. T We don't know enough to give a reasonable answer 3. The argument from consciousness Perhaps machine only looks to be doing something intelligent But it is not even pretending Really a Cartesian point. Applies as well to other people, as to machine. 4. Machines cannot do everything Insofar as it is a well formed question, no good reason to believe this 5. Cartesian objection Machine cannot think of itself. It cannot perform the cogito 6 the machine is not creative Only does what it has been programmed to do. Maybe human beings are not creative either 7. We do not have rules for every piece of behavior This a variation on 6 8. Machine lacks the power of ESP. A genuinely bizarre objection
