Property Dualism (Jackson) Flashcards
What is the Goal of Frank Jackson?
Physicalism is false, any theory that depicts the world as entirely physical is false
Does Jackson offer explicit proof or a deductive logical conclusion as to why physicalism is false?
no
Who offers a intuition pump?
Frank Jackson
Does Jackson admit that he could be wrong?
yes but very improbable he is
What Argument does Frank Jackson Introduce?
The Knowledge Argument
Briefly Describe the knowledge argument
-Mary raised in black and white room
-has access to everything there is to know about color red in the physical world
-learns all the physical facts about red
-then released into the world and sees red for the first time
DID MARY LEARN ANYTHING WHEN SHE SEEN THE COLOUR RED FOR THE FIRST TIME
According to Jackson did Mary learn anything when she seen the color red for the first time?
yes, even if she knew absolutely everything about the color red she still would have learnt something therefore even if she had physically known everything about red, she was not able to capture the sensation (quaila) of seeing red
Clarifying the Argument (missing)
What are is Paul Churchland’s 1st objection
Paul rewords the knowledge argument in the following way
1) Mary knows everything there is to know about brain states and there properties (DESCRIPTION)
2) ~Mary knows everything that there is to know about sensations and their properties (ACQUAINTANCE)
3) Therefore, sensations and their properties are not equal to brain states and their properties
What was Churchlands 1st objection about in lay terms
Jackson is actually using the term KNOWLEDGE in two different ways.
Knowledge by DESCRIPTION
Knowledge by ACQUAINTANCE
What is Jackson Reply to Churchland’s 1st Objection?
That was Churchland 1st criticism is misleading. Jackson argument has nothing to do with types of knowledge, the fact is she does not know everything before release. Still does not have complete knowledge.
The knowledge argument can be clarified further by:
1) Mary before her release knows everything physical there is to know about other people
2) Mary before her release does not know everything there is to know about other people
3) Therefore there are truths about other people (and herself) which escape the physicalist theory
What was Churchland’s 2nd Objection
The knowledge argument is too strong and therefore apply it to dualism and about the dualist teaching the laws of quail. Upon her release she still would’ve learnt something
What was Jackson’s response to Churchland’s 2nd objection
Churchland is mistaken, the dualist admits they can’t tell her everything and shouldn’t expect dualists should. Jackson is confused then what the dualist argues
What was Jackson’s response to help Churchland’s 2nd objection
they would have to change the first premise:
1) Mary before her release knows everything of the dualist sort about other people
However, this isn’t plausible because the dualist would deny that you can capture all the physical stuff by lecture and rather they dont think you can describe everything physically
What is Churchland’s 3rd objection?
That there is a chance that Mary with all her physical information could figure out what it is like to see the color red
What was Jackson’s response to help Churchland’s 3rd objection
What Mary can or cannot imagine is irrelevant. Imagination has nothing to do but rather than what she knows
Lets grant her the imagination of red (she’s still going to learn something when she gets release)
fill in the blanks for a quote from Jackson regarding his objection to Churchland’s 3rd criticism:
“If her knowledge is defective, despite being all there is to know according to ____, whatever her powers of imagination.” -Jackson
physicalism then physicalism is false
What does Jackson determine there to be left?
~physicalism
Fill in the quote by Jackson:
“Nothing you could tell of the ______captures the smell of a rose, for instance. Therefore, _______.” (Jackson Epiphenomenal Qualia 127)
1) physical sort
2)physicalism is false
Does the knowledge prove Descartes Dualism correct?
no he’s still sort of right and wrong
what are properties properties of?
some thing
what is weight, height, shape?
These are properties of our bodies
and what category of properties are weight, height, shape?
physical properties
What problem does the Knowledge argument generate?
how do we categorize everything
