What is dualism?
The metaphysical view that there are 2 fundamentally distinct and irreducibly different kinds of substances: body & mind (soul)
Why is dualism appealing?
- it agrees with an idea of human life that is advanced by many religions
- it fits very well with the idea that there are certain features of our mental life that cannot be physical.
What is Descartes's foundation for epistemology in his second meditation?
- That he knows he exists
- "What is this 'I' that I know?"
- He is not a body = material substance
- The body changes, but he remains the same

- The essence of bodies is extension
- The essence of minds if thought
- If I am a thinking substance, I am not a body
- I am a thinking substance
- Therefore, I am not a body
What are some problems with dualism?
- Using doubt and property divergence
- if A has a certain property and B does not, A≠B
- You can't use doubt as a basis for claiming not-identity
- The mind-body problem
- if A has a certain property and B does not, A≠B
- You can't use doubt as a basis for claiming not-identity
What is the mind-body problem?
- The difficulty of explaining how the mental activities of human beings relate to their living physical organisms
- How then can one's mind affect one's body?
- How can one's body affect one's mind?
- Drinking alcohol impairs my thinking ability
- Why will damage to the brain result in impaired thinking and cognition?

- How can one's body affect one's mind?
- Drinking alcohol impairs my thinking ability
- Why will damage to the brain result in impaired thinking and cognition?

- equate the mind with the behavior
What was Ryle's aim/purpose on his attack on dualism?
The central principles of the official doctrine are unsound and conflict with the whole body of what we know about minds.
What did Ryle meant with "official doctrine"?
- The Doctrine of the Ghost in the Machine
- Every human being has (or is) both a mind and a body
- There is a polar opposition between mind and matter
- What the mind wills, the legs, arms, and the tongue execute
- In consciousness and introspection he is directly and authentically appraised of the present states and operations of his mind.

- "Where is the university?"
- University is made up of other categories below it
- Ryle thought dualism commited a category mistake.
- "Where is the university?"
- University is made up of other categories below it
What is the category mistake that the proponents of the doctrine make?
- We know how to use words such as "process," "cause," "effect," etc.
- Such words can't be referring to what is unobservable, to use them that way is a category mistake
- Proponents of the official doctrine use those words to refer to the unobservable mind
- Therefore, proponents make a category mistake
What are some problems with the sameness of soul criterion?
- How do we know souls exists?
- How do we know that we have the same soul over time?
- The mind-body problem
- Why will damage to your brain effect who you are as a person?
Sameness of body/brain criterion
- The body plays an important in how we recognize and identify as persons
- Are you the person you are because of your body/brain?
- Is sameness of body/brain that which makes a person the same person over time?
