3 ideas
| 10800 | The values of variables can't determine existence, because they are just expressions [Ryle, by Quine] |
| Full Idea: Ryle objected somewhere to my dictum that 'to be is to be the value of a variable', arguing that the values of variables are expressions, and hence that my dictum repudiates all things except expressions. | |
| From: report of Gilbert Ryle (works [1950]) by Willard Quine - Reply to Professor Marcus p.183 | |
| A reaction: I have a lot of sympathy with Ryle's view, and I associate it with the peculiar Millian view that we can somehow replace a name in a sentence with the actual physical object. Objects can't be parts of sentences - and maybe they can't be 'values'. |
| 14367 | An explanation is a causal graph [Woodward,J, by Strevens] |
| Full Idea: On Woodward's manipulationist view, an explanation would take the form of a causal graph. | |
| From: report of James Woodward (Making Things Happen [2003]) by Michael Strevens - No Understanding without Explanation 1 | |
| A reaction: The idea is that causation is all to do with how nature responds when you try to manipulate it. I'm certainly in favour of tying explanation closely to causation. |
| 7435 | Dispositions are second-order properties, the property of having some property [Jackson/Pargetter/Prior, by Armstrong] |
| Full Idea: It was proposed that dispositions are second-order properties of objects: the property of having some property. | |
| From: report of Jackson/Pargetter/Prior (Three theses about dispositions [1982]) by David M. Armstrong - Pref to new 'Materialist Theory' p.xvii | |
| A reaction: It seems more plausible to say that dispositions are first-order properties - that is, properties are dispositions, which are causal powers. A disposition to smoke is to have a causal power which leads to smoking. |
