Review of Descartes on Mind and Body

•           According to Descartes, what is body?

•           According to Descartes, what is mind?

•           According to Descartes, what sorts of things can we construct mathematical models of?

•           What might Descartes say about the possibility of a thinking machine?

Thinking Machines and AI

•           Some history regarding “thinking” machines

•           What is AI?

The Kinds of Machines at Issue

•           When Turing asks whether machines can think, what kinds of machines does he have in mind?

•           What methods of design is he willing to permit?

The Kinds of Machines at Issue

•           Some features of digital computers:

     –      Store

     –      Executive unit

     –      Control

•           Does the type of hardware matter with respect to the issue of whether a system is a digital computer?

Imitation Game

•           Turing wants to replace the question, “Can machines think?” with another question.  What is that other question?

•           What is his motivation for replacing his original question with his new question?

Evaluation of the Turing Test

•           If a machine can think, then it can pass the Turing test.  Is that true?  Is passing the Turing test necessary for a machine being able to think?  Does Turing think it is necessary?

•If a machine can pass the Turing test, then it can think.  Is that true?  Is passing the Turing test sufficient for a machine being able to think?  Does Turing think it is sufficient?
