- Indirect Realism Problems
- Problem 1
- can't know if our sense data matches reality
- "scepticism about the nature of mind independent objects"
- veil of perception
- Russell 1 - same info from multiple senses
- criticism - sometimes senses don't add up
- Russell 2 - recognise similarities + differences in objects so must be difference in reality
- criticism - can't assume differences in sense data correspond with reality
- survival - perception must be good enough to survive
- criticism - could be nothing like reality but as long as senses work systematically we can survive
- animals perceive the world differently
- criticism - could be nothing like reality but as long as senses work systematically we can survive
- common perception - people see things roughly the same as we do
- criticism - what if we are all wrong
- Problem 2
- "scepticism about the existence of mind independent objects"
- if all we see is sense data we can't prove existence of mind independent objects
- agreed by Locke + Russell
- Locke 1 involuntary nature of perception - we cannot control what we see e.g. seeing someone get killed
- criticism - no control over our dreams but this doesn't come from an external cause
- Locke response - never mistake being awake with being asleep - waking life more vivid than our dreams so must be reality behind it
- "they must be produced in my minds by some external cause"
- criticism - no control over our dreams but this doesn't come from an external cause
- Locke 2 coherence of senses - primary properties perceived by more than one sense
- development Cockburn - not only do multiple sense confirm properties but learn to make connections between properties (predictability)
- criticism - just like dreams could still be in a consistent illusion
- development Cockburn - not only do multiple sense confirm properties but learn to make connections between properties (predictability)
- Conclusion - Russell Best Hypothesis
- "surely we might say, the existence of physical objects is simply a better, simpler and stronger explanation than these options"
- Problem 1
