- Indirect realism
- Physical objects exist but their properties are dependant on the mind
- Primary properties: shape, size, extension and other physical properties of an object
- Secondary properties: subjective properties, such as colour, taste, smell, texture and sound
- Has three parts: perceiver ==> perception ==> real world
- Veil of perception
- invisible 'barrier' between the real world and our perception
- Veil of perception
- Locke: sense data

- We uses sense data to build a picture of the physical world
- Qualia: the subjectiveness of something
- Weaknesses and counter arguments
- Scepticism of the nature of the mind: independent objects
- If we cannot directly perceive objects, how do I know if my perception of them is correct?
- Response: the veil of perception- if the VOP changed our view of the real world too much, then we would not survive
- We can eat and hunt, which are visual perceptions caused by the real world
- Scepticism about the existence of mind: independent objects
- If Descartes demons theory is true, then how do we know that our sense data is actually perceiving the real world, and not some evil image?
- Responses
- Locke: we lack choice in what we perceive and we can verify them through various sense
- If I can smell flowers and see/touch them at the same time, we can probably conclude that they exist
- Russell: the external world is the best idea, it is better than having no real world
- Locke: we lack choice in what we perceive and we can verify them through various sense
- Kant: we should call the perceived world the real world, as it is beyond our comprehension to know what the real world is actually liek
- If we cannot justify that there is a real world, then we cannot conclude that there is one
- Scepticism of the nature of the mind: independent objects
- Strengths
- Intuative: easily recognisable that there is a gap between perception and the real world
- Sunlight take 8 mins to reach the earth
- Intuative: easily recognisable that there is a gap between perception and the real world
- Physical objects exist but their properties are dependant on the mind
