Class Review Flashcards
Cartesian Dualism
the doctrine that thinking beings possess immaterial souls entirely distinct from their physical bodies
Argument From Doubt
(1) I can doubt the existence of my brain and my body.
(2) I cannot doubt the existence of my mind.
Therefore
(Conclusion) My mind is not the same thing as my body or brain.
Leibniz’s Law
If A and B are the same object, then they have exactly the same properties. In other words, if A and B do not share all the same properties, then A and B are not the same object.
Why is the argument from doubt fallacious?
because it involves an illegitimate use of Leibniz’s Law.
The Conceivability Argument
(1) If I can conceive of some state of affairs without contradiction, then the state of affairs is possible. (God could bring it about)
(2) I can conceive of myself as existing without my body
Therefore
(3) It is possible for my body to exist without my body existing.
But,
(4) It is not possible for my body to exist without my body existing.
Hence (by Leibniz’s Law)
(conclusion) I am distinct from my body.
Arnauld’s Objection/Response and what does he give as an example?
The mere fact Descartes can conceive of some state of affairs does not sow that the state of affairs is possible. We can conceive of a triangle that does not follow the Pythagorean theorem and could not bring it into reality.
What does it mean for something to be ‘metaphysically possible’?
A way the world could have been
Amnesia Argument
Suppose I have amnesia.
(1) If I can conceive of a state of affairs, that that state of affairs is possible.
(2) I can conceive of a world in which I exist but HS does not exist.
Therefore,
(3) It is possible for me to exist w/o HS existing.
But,
(4) It is impossible for HS to exist w/o HS existing
Hence (by LL)
(conclusion) I am not HS
What was Princess Elisabeth’s Challenge?
How could an immaterial substance, existing outside physical universe, exert any kind of causal impact upon physical processes (soul)?
What was Descartes’ Response to Princess Elisabeth’s Challenge? How convincing is his response?
Only the pineal gland (seat of the soul) is affected. Not convincing bc it still does not explain how the nonphysical affects the physical.
Interactionism (and how its received)
the doctrine that the mind can enter into causal interactions with the physical world (almost everyone believes in this)
Materialism and what it thinks of mental
the doctrine that everything exists in physical (material). the mental is an extremely complex manifestation of underlying physical phenomena
What does objecting to materialism do?
Leaves out the subjective character of experience, omits what it is like to feel pain, see color, …
Consciousness
qualitative aspect of experience (what it is like)
The Mary Argument
(1) Mary knows all the physical facts concerning human color vision before leaving the black-and-white room.
(2) But there are some facts about human color vision that Mary does not know before leaving the black-and-white room.
Therefore,
(conclusion) There are non-physical facts concerning human color vision
Supervenience
the doctrine that, if two entities share all the same physical properties, then they also share all the mental properties
What is the relationship between materialism and supervenience?
Anyone who endorses materialism also endorses supervenience.
What is the inverted spectrum?
When two people are actually seeing two different colors, but still describe it as all the same properties. But this can only be seen as a 3rd party and we cannot prove ourselves so rejoinder: maybe this is not true at all.
Descartes’ thoughts on Machine Thought
‘no machine could speak a language, so not machine could think’ ‘no thinking beings are composed of both bodily machine and immaterial soul’
Turing Test
computer passes the TT if we cannot discern if it is a machine, rather than a human being, during the Imitation Game
What are the three resulting views of Machine Thoughts and Turing Test?
(1) If a machine passes the TT, then it can think
(2) If no machine can think. A machine that passes the TTcan only simulate thought
(3) If a machine passes the TT, then that provides us with good reason to believe that it can think
The Computational Theory of Mind
Mind is just a computer (made of neurons instead of silicon). Mental activity is just computational activity. (mind is software, not hardware)
Syntactic Manipulation
computational models place a big emphasis on syntactic man. Basic idea is that a computer manipulates pieces of data according to mechanical rules
What are the three theories of mind?
Dualistic: mind=soul
Behaviorism: mind=behavioral dispositions
Computational Theory of Mind: mind=computer
What are the aspects of mentality?
Qualitative aspects (consciousness). Representational aspects (beliefs about the world/represent the world)
