Direct Realism Flashcards
1
Q
Direct realism
A
The immediate objects of perception are mind-independent objects and their properties
2
Q
Argument from common sense
A
- most basic intution is that we perceive mind-independent objects and their properties
- doesn’t prove we do, but it means other theories of perception claim that basic intution is incorrect
- direct realism fits perfectly with our basic intuition
3
Q
Issue of illusion
A
- In illusions we are perceiving mind-independent objects with properties they don’t in fact have
- shows that direct realism must be false
4
Q
Response to the issue of illusion
A
- when a stick is half submerged in water looks crooked, there is nothing that is crooked
- the stick itself has the relational property of looking crooked when half submerged in water, and yet simultaneously has the non-relational property of being straight
- sometimes we perceive the properties that MIPO have that dont related to how they’re being perceived -> sometimes we perceiver the properties that MIPO have that do related to how they are being perceived
5
Q
Issue of perceptual variation
A
- Direct realisms claim
- yet the immediate objects of perception can vary without any change in the so called ‘mind-independent object’, just by altering the perceptual variation (viewing a table from different angles)
6
Q
Response to perceptual variation
A
- some of the perceived propelires of the mind-independent object are relational, which means that they are properties the mind-independent object has in relation to being perceived
- we could say the ‘real’ property of a table, is the one normal observers perceive under normal conditions
7
Q
Issue of hallucinations
A
- in the case of hallucinations the immediate object of perception is not actually a mind-dependent object at all, simply not even there even though we thought it to be
- hallucinations can be subjectively indistinguishable from veridical perceptions
- if two perceptual experiences are subjectively indistinguishable, the best explanation for this is that they are perceptual variations of the same thing
- therefore both hallucinations and veridical perceptions the immediate objects must be mind-dependent objects (sense data)
- therefore direct realism is false
8
Q
Response to hallucinations
A
- veridical perceptions are perceptions that are true
- hallucinations are not veridical perceptions, they are a different type of mental state, in hallucinations we dont perceive, we imagine
- the fact that hallucinations are subjectively indistinguishable from veridical perceptions does not tell us anything significant about veridical perceptions
- the DR theory is about veridical perceptions not hallucinations, so what happens in them is irrelevant to DR
- hallucinations are not a threat to direct realism
9
Q
Time-lag issue
A
- it takes time of light and sound waves to travel from the so-called mind-independent objects to the perceiver
- how are we seeing things before we’re supposed to see them?
10
Q
Response to time-lag issue
A
- confusion between how we perceive and what we perceive
- its part of the equipment of perception, not the thing that perception is used on
