If the cat reappears in a new position, presumably it has passed through the intermediate positions [Russell]
     Full Idea: If the cat appears at one moment in one part of the room, and at another in another part, it is natural to suppose that it has moved from the one to the other, passing over a series of intermediate positions.
     From: Bertrand Russell (Problems of Philosophy [1912], Ch. 2)
     A reaction: This example seems perfect as an illustration of inference to the best explanation (now called 'abduction'), and that seems to me the absolute key to human knowledge. The cat example is what made me a devotee of Bertrand Russell.
Belief in real objects makes our account of experience simpler and more systematic [Russell]
     Full Idea: The belief that there are objects corresponding to our sense-data tends to simplify and systematize our account of our experiences, so there seems no good reason for rejecting it.
     From: Bertrand Russell (Problems of Philosophy [1912], Ch. 2)
     A reaction: This hardly counts as a good argument against the logical possibility of global scepticism, but it is a nice statement of the concept of 'best explanation', which obviously requires some sort of rational criteria if it is to provide a theory of knowledge.
