Indirect Realism
Indirect realism is the view that:
The external world exists independently of the mind but we perceive the world indirecly via sense data
indirect realism says the immediate object of perception is sense data. This sense data is caused by, and represents, the mind-independent external world.
Most philosophers who argue for indirect realism start with the problems for direct realism. The many differences between reality and our perception of it, make direct realism implausible.**
Instead, they claim that what we really perceive is sense data.
SENSE DATA
Sense data can be described as the content of perceptual experience
It is not a physical thing, it exists in the mind. However, sense data is said to be caused by mind-independent physical objects .
Sense data is private. No ones else can see your sense data
