13. Knowledge Criteria / D. Scepticism / 5. Dream Scepticism
Dreams aren't a serious problem. No one starts walking round Athens next morning, having dreamt that they were there! [Aristotle]
     Full Idea: Is it really an issue whether things are true that appear to those asleep or to those awake? No one in Libya who dreamt he was in Athens, would set out for the Odeon next morning!
     From: Aristotle (Metaphysics [c.324 BCE], 1010b09)
Dreams can be explained fairly scientifically if we assume a physical world [Russell]
     Full Idea: Dreams are more or less suggested by what we call waking life, and are capable of being more or less accounted for on scientific principles if we assume that there really is a physical world.
     From: Bertrand Russell (Problems of Philosophy [1912], Ch. 2)
     A reaction: This sounds a bit circular, since scientific principles depend entirely on the assumption that there is a physical world. No doubt if we assume fairies, 'fairy lore' will explain everything. 'Explanation' is the basic concept here.
