  7. Jerry Fodor Modularity of the Mind

  8. McDermott’s Chapters 1. Shows his intent to overcome first order flaws Places his theory as a second order theory 2. Surveys state of AI research 3. Detailed explanation of his Theory of Consciousness 4.Answers Objections Ill-defined terms computer and Symbol 5. Defines Computer and Symbol 6. Effects of theory on religion and ethics

  9. McDermott’s Argument Second-Order Theory of Consciousness: Digital computer simulates Modules of Brain Activity Includes Qualia Disagrees with Dennett’s Intentional Stance Appeals Little to Neuroscience Computationalism and Functionalism

  10. The Problem: “How can a purely physical organ—the brain—experience?

  11. Answer: Humans have minds because they (or their brains) are computers.

  12. Development: Computers have things in common with the brain Both make and use models of their worlds Both can (theoretically) experience qualia in their own way Both of these elements occur via codes and molecules Phenomenal Consciousness originates: For Neurologists, in protoplasm (living, feeling parts) For McDermott, opposite intuition: Feeling is unrelated to “being alive” “The great majority of living things never feel anything.” Therefore, both living systems and other organisms can have feelings Should therefore accept H that organisms have desires, beliefs, and feelings somehow similar to ours Consciousness is thus possible in organisms such as computers.

  13. Paper #2: “AI & Intelligence” In order to refute critics—such as Searle—AI must create computational models explaining Vision, Language, Locomotion First section: Overview of Consciousness Theories Phenomenological Consciousness is a property of a computational system if models itself as experiencing. Middle Section: Defines a computational system in detail Shows how one can exhibit intentionality Shows that consciousness is modeling self as having experiences So, computers (s.f. intelligent robots) can theoretically be conscious. And human beings can, conversely, be seen as robotic.
