| 15833 | Tell cleverness from answers, but wisdom from questions [Mahfouz] |
| Full Idea: You can tell whether a man is clever by his answers. You can tell whether a man is wise by his questions. | |
| From: Naguib Mahfouz (works [1998]) | |
| A reaction: [Popped up on Twitter. I am adjusting to the 21st century] The observation is simplistic, of course, but very nice indeed. |
| 22137 | Observation can force rejection of some part of the initial set of claims [Duhem, by Boulter] |
| Full Idea: Logic and observation alone do not force a scientist to reject a scientific claim if experimental observations so not turn out as expected. The scientist must reject something of the initial set of claims, but that is a matter of choice. | |
| From: report of Pierre Duhem (The Aim and Structure of Physical Theory [1906]) by Stephen Boulter - Why Medieval Philosophy Matters 2 | |
| A reaction: This is a key point against any simplified Popperian notion of falsification. Tiny observations can't kill huge well supported theories. |
| 18197 | Experiments only test groups of hypotheses, and can't show which one is wrong [Duhem] |
| Full Idea: The physicist can never subject an isolated hypothesis to experimental test, but only a whole group of hypotheses; when the experiment is in disagreement with his predictions ...it does not designate which one should be changed. | |
| From: Pierre Duhem (The Aim and Structure of Physical Theory [1906], p.187), quoted by Penelope Maddy - Naturalism in Mathematics II.2 | |
| A reaction: This is the idea frequently invoked by Quine, in support of his holistic view of scientific knowledge (along with Neurath's Boat). |
| 8326 | Science has shown that causal relations are just transfers of energy or momentum [Fair, by Sosa/Tooley] |
| Full Idea: Basic causal relations can, as a consequence of our scientific knowledge, be identified with certain physicalistic [sic] relations between objects that can be characterized in terms of transference of either energy or momentum between objects. | |
| From: report of David Fair (Causation and the Flow of Energy [1979]) by E Sosa / M Tooley - Introduction to 'Causation' §1 | |
| A reaction: Presumably a transfer of momentum is a transfer of energy. If only anyone had the foggiest idea what energy actually is, we'd be doing well. What is energy made of? 'No identity without substance', I say. I like Fair's idea. |
| 10379 | Fair shifted his view to talk of counterfactuals about energy flow [Fair, by Schaffer,J] |
| Full Idea: Fair, who originated the energy flow view of causation, moved to a view that understands connection in terms of counterfactuals about energy flow. | |
| From: report of David Fair (Causation and the Flow of Energy [1979]) by Jonathan Schaffer - The Metaphysics of Causation 2.1.2 | |
| A reaction: David Fair was a pupil of David Lewis, the king of the counterfactual view. To me that sounds like a disappointing move, but it is hard to think that a mere flow of energy through space would amount to causation. Cause must work back from an effect. |
