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

Slide14

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

Slide15

The Problem:

“How can a purely physical organ—the brain—experience?

Slide16

Answer:

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

Slide17

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.

Slide18

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.

Question to Ponder: “Are we anything more than computers and robots?”
