| 5363 | 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. |
| 5367 | 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. |
| 12769 | Inference to best explanation contains all sorts of hidden values [Fraassen] |
| Full Idea: The very phrase 'inference to the best explanation' should wave a red flag for us. What is good, better, best? What values are slipped in here, under a common name, and where do they come from? | |
| From: Bas C. van Fraassen (The Empirical Stance [2002], 1.5) | |
| A reaction: A point worth making, but overstated. If we are going to refuse to make judgements for fear that some wicked 'value' might creep in, our lives will be reduced to absurdity. |
| 12768 | We accept many scientific theories without endorsing them as true [Fraassen] |
| Full Idea: The choice among theories in science may be a choice to accept in some sense falling far short of endorsement as true. | |
| From: Bas C. van Fraassen (The Empirical Stance [2002], 1.5) | |
| A reaction: When put like this, it is hard to deny the force of Van Fraassen's reservations about science. Lots of people, including me, use scientific theories as working assumptions for life, with nothing like full confidence in their truth. |
