9429 | Many forms of reasoning, such as extrapolation and analogy, are useful but deductively invalid [Mumford] |
Full Idea: There are many forms of reasoning - extrapolation, interpolation, and other arguments from analogy - that are useful but deductively invalid. | |
From: Stephen Mumford (Laws in Nature [2004], 04.4) | |
A reaction: [He cites Molnar for this] |
4731 | Good reasoning will avoid contradiction, enhance coherence, not ignore evidence, and maximise evidence [O'Grady] |
Full Idea: The four basic principles of rationality are 1) avoid contradiction, 2) enhance coherence, 3) avoid ignoring evidence, and 4) maximise evidence. | |
From: Paul O'Grady (Relativism [2002], Ch.5) | |
A reaction: I like this, and can't think of any additions. 'Coherence' is the vaguest of the conditions. Maximising evidence is still the driving force of science, even if it does sound quaintly positivist. |
