- IR leads to scepticism about the nature and the existence of the external world
- There would be no difference to the perceiver if there was no physical world
- If we only perceive sense data and not the object itself, how can we know anything about the external world
- We have know way of knowing that sense data is an accurate representiation of the external world
- Maybe there isn't an external world at all?

- When we perceive sense data, it must be part of the external world as we are unable to control them

- We cannot perceive a table as brown and then suddenly perceive the same table as half the size and suddenly hot pink

- Different senses confirm information of one another
- You can write something on apiece of paper and see the words, you can get someone to read it and you hear it through a different source
- How do you not know that that source exists?
- If its just sense data that is personal, this could happen in your mind and we wouldn't know
