Theories of Mind Study Notes

Theories of mind are philosophical perspectives that explain the relationship between mental events and physical events.

Definition: A philosophical theory that posits the existence of two distinct substances: mental and material.
Illustration: A mental event such as the feeling of pain is a separate entity from the material event of jumping up after sitting on a tack.

Definition: A theory suggesting that mental events and physical events occur in parallel but do not interact.
Example: If a person feels pain from sitting on a tack, there is a parallel mental event (feeling of pain) and a material event (jumping up) that occur simultaneously without causal interaction.

Definition: A philosophical view that denies direct interaction between mental and physical events and asserts that God intervenes to create the correlation when mental and material events occur.
Example: The mental event of having the desire to jump is paired with the material event of jumping up only when an occasion for such interaction occurs through divine intervention.

Definition: The school of thought which posits that reality is fundamentally mental and that the material world is an extension of the mind's perceptions.
Illustration: Both the mental feeling of pain and the consequential action (jumping up) are considered manifestations of a mental reality rather than purely physical events.

Definition: A view that considers mental events as byproducts ('epiphenomena') of physical processes, which means mental states do not exert any influence on physical actions.
Example: The sensation of pain is produced by physical processes, but it does not influence the action of jumping up; the action is purely a physical reaction.

Definition: A psychological perspective which studies observable behavior and dismisses introspective methods. It focuses on the connections between stimuli and responses.
Illustration: The material event of sitting on the tack leads to a disposition to jump, characterized by an observable behavioral response.

Definition: The theory that posits that mental states are identical to physical states in the brain; each mental event corresponds to a particular brain state.
Example: The mental event of feeling pain when one sits on a tack is directly identified with a specific neurological event in the brain.

Definition: A theory that emphasizes the functional role played by mental states in a system rather than their physical or material composition.
Key Points:
- Behavioral Reactions:
  - Action: Sat on tack leads to the pain state.
  - Result: Behavior exhibited includes jumping up.
  - Beliefs:
  - That the tack is sharp.
  - That skin is injured.
  - Desire:
  - For pain relief leads to behavior such as getting Advil and a Band-aid.
- Realizers: Functional states are realized by various physical states; this theory allows for multiple realizability across different systems.

Definition: A theory that suggests mental states represent the world in specific ways and that these representations drive behavior.
Application:
- Complete behavioral chain:
  - Behavior: Sat on tack leads to pain state initiating a jumping action.
  - Underlying beliefs and desires initiate towards the goal of pain relief through actions such as seeking medical aid.
- Realizers: Just like in functionalism, key behaviors are realized by specific mental states that correspond to the physical events involved in pain and response.
Summary of Key Concepts
The relationship between mental and physical events is contested across multiple philosophical theories, each with unique definitions and implications about how one affects the other, or if they exist independently.
