Indirect Realism Flashcards
What is our sense-data?
Mind-dependant
What are sense-data caused by and represent?
Physical objects
How do we perceive sense-data?
Directly
How do we perceive physical objects?
Indirectly
Example of perceptual variation?
Desk remains rectangular, even as the way it looks to me changes as I look at it from different angles.
What does this mean we’re immediately aware of in perception
It isnt exactly the same as what exists independently of our minds
What does the argument from perceptual variation shows?
We do not perceive physical objects directly.
What shows that we don’t know that physical objects exist?
The only access we have to them is through our sense-data.
What is a bad response to scepticism?
Other people see the same thing
How does scepticism object to the response?
How can we know other people exist.
Claim that is true or false
Physical object exist or do not exist
Treat the claim as?
A hypothesis
Better hypothesis?
Physical objects exist and cause my sense data.
Can’t control?
Perceptual experiences
Different sense do what?
Confirm the same information
Indirect Realism
Infer the existence of physical objects
Sense-data
How we perceive physical objects.
Not a hypothesis
Existence of physical objects
Systematic correlations
What we experience and the nature of the world
Doesn’t tell us
What underlies the correlation
Russell’s distinction
Physical space and apparent space
Shape
Apparent space
Physical space causes our sense-data
We exist in physical space
Something that appears further
Longer to walk through physical space to get there.
All we can know about physical space
What secures this correspondence.
Can’t know space or distance
In themselves
2 objects have the same colour
2 objects have something in common
Extend point
All properties of an objects.
Physical objects secure relations of
Similarity and difference.
