The Mind-Body Problem Today Flashcards
What is dualism?
The argument that the mind and body are 2 separate substances
What is monism?
The argument that the mind and body are one substance
What was Descartes’ view on the mind-body problem? What type of dualism is this?
He argued that the mind and body were made up of 2 separate things. This is known as substance dualism.
What is parallellism? Who argued in favour of this?
A form of dualism where the mind and body do not interact directly but live separate, parallel lives that are both caused by God.
Leibniz argued in favour of this.
What are the 3 property dualisms?
- Epi-phenomenalism
- Pan-psychism
- Emergent materialism
What are the 4 physicalisms?
- Identity theory
- Functionalism
- Eliminative materialism
- Behaviourism
What are 5 schools of continental philosophy that discuss the mind-body problem?
- Existentialism
- Phenomenology
- Structuralism
- Psychoanalytic theory
- Critical theory
Epi-phenomenalism:
Who proposed it?
What is it?
In epi-phenomenalism, the physical brain causes mental states.
BUT mental states have no causal role in changing physical states.
This was proposed by Huxley.
What are 3 arguments FOR epi-phenomenalism?
Neuropsychology - many reactions and functions don’t require conscious awareness
Behaviourism - there has been great progress made without even referring to the mind
Neurophysiology - conscious awareness may come long after the brain states that cause it (Libet)
What are 4 arguments AGAINST epi-phenomenalism?
Evolutionary - if the mind has no causal role, then why has it evolved?
Interaction - the same problem as with substance dualism - how do mind & body interact?
Logical - how can we know about the existence of the mind, if the mind can’t affect the brain?
Empirical - even Libet claimed that we have a ‘conscious veto’ over our actions.
Pan-psychism:
What is it?
Who proposed it?
The idea that there are mental properties in EVERYTHING and mind is a non-physical property of all matter.
This was proposed by Nagel.
What were Nagel’s 4 premises for pan-psychism? What was his conclusion? What problem does it solve?
- Everything is physical
- But also, the mind is real (just in a different way)
- Mind can’t be reduced to physical states
- Mind can’t emerge from physical states
His conclusion was: all matter must have mind.
This solves the hard problem of consciousness (how does the brain produce consciousness?).
What were 3 arguments AGAINST pan-psychism?
- Empirical: it can’t (yet) be tested scientifically
- Meaningless: worse than un-testable, it’s not even a theory yet (Searle)
- Pan-psychists reply saying there is no evidence against it, and it is elegant
Emergent materialism:
What is it?
Who proposed it?
The idea that there are causal relationships between the body and the mind.
All mental states are caused by a physical state. Mental states do not always cause mental states
Mind depends on, but is not the same as, the body.
This was proposed by Chalmers.
What is an argument for emergent dualism?
Physical properties can be described at multiple levels.
Eg. Water.
- The properties of snowflakes/tsunamis can’t be derived from those of H2O.
These higher-level properties emerge from the lower-level properties, within the constraints of a particular physical system.
So… Can you explain consciousness in terms on singular neurones? No.
