Key passages
“we possess a clear and distinct knowledge of pain, colour, and other things of this sort, when we consider them simply as sensations or thoughts; but that, when they are judged to be certain things subsisting beyond our mind, we are wholly unable to form any conception of them.”
We clearly understand pain and color only as mental experiences; if we try to think of them as real things outside the mind, we have no real understanding of them.
Key distinction between subjective sensation and objective reality.
