- Direct realism
- The external world exists independently of the mind
- We perceive the external world directly
- If we see a tree then there is a tree
- Immediate objects of perception are mind independent objects
- We perceive the external world directly
- Argument from illusion
- We perceive the external world directly as it is
- But with illusion there is an obvious difference between our perception and reality
- When a pencil is placed in a glass it is crooked but it isn't actually crooked
- If DR was true then the external world would be exactly as we perceive
- But the pencil just has the property of looking crooked even though its not crooked
- DR is concerned with immediate objects tho which includes the pencil looking crooked
- But the pencil just has the property of looking crooked even though its not crooked
- If DR was true then the external world would be exactly as we perceive

- We perceive the external world directly as it is
- Argument from hallucination
- When we hallucinate we perceive things that are not there
- But they're not as vivid as physical objects
- Sometimes they are extremely vivid therefore this cannot counter this point
- What causes these perceptions cannot come from the external world directly
- How do we know the hallucinations don't exist?
- Because others do not perceive it
- We cannot trust our feeling
- Because others do not perceive it
- How do we know the hallucinations don't exist?
- What causes these perceptions cannot come from the external world directly
- Sometimes they are extremely vivid therefore this cannot counter this point
- But they're not as vivid as physical objects
- When we hallucinate we perceive things that are not there
- Argument from perceptual variation
- Bertland Russell
- Differences in perceptual variation causes issues for direct realism
- Famous dress conflict
- Blue or black
- According to DR there should be no difference between perception and reality
- Gold and white
- We are all perceiving the same blue and black dress but from specific angles and lights it looks white and gold
- But there is perceptual variation nevertheless therefore DR is weak
- According to DR there should be no difference between perception and reality
- Gold and white
- Blue or black

- Time lag argument
- The sun is 149,600,000km from the earth
- Light traveks at 299,792,458 per second
- It takes approximately 8 minutes for light to reach the earth
- When we look at the sun we're actually perceiving it from how it was 8 minutes ago
- not directly
- If it exploded we wouldn't know, we would be perceiving something that is not there
- This is similar to the hallucination problem but everyone would be perceiving the same thing
- All of us would see the sun even though it was not there
- DR respond that this does not under mind the theory are you are not perceiving the light from the sun directly
- This still shows DR has many flaws and is not be the correct basis
- A better theory would be one that bases their theory on perceiving the external world indirectly and via our senses
- This still shows DR has many flaws and is not be the correct basis
- DR respond that this does not under mind the theory are you are not perceiving the light from the sun directly
- All of us would see the sun even though it was not there
- This is similar to the hallucination problem but everyone would be perceiving the same thing
- If it exploded we wouldn't know, we would be perceiving something that is not there
- not directly
