| 18889 | Ostensive definitions needn't involve pointing, but must refer to something specific [Salmon,N] |
| Full Idea: So-called ostensive definitions need not literally involve ostension, e.g. pointing, but they must involve genuine reference of some sort (in this case reference to a sample of water). | |
| From: Nathan Salmon (Reference and Essence (1st edn) [1981], 4.11.2) |
| 14627 | S4, and therefore S5, are invalid for metaphysical modality [Salmon,N, by Williamson] |
| Full Idea: Salmon argues that S4 and therefore S5 are invalid for metaphysical modality. | |
| From: report of Nathan Salmon (Reference and Essence (1st edn) [1981], 238-40) by Timothy Williamson - Modal Logic within Counterfactual Logic 4 | |
| A reaction: [He gives references for Salmon, and for his own reply] Salmon's view seems to be opposed my most modern logicians (such as Ian Rumfitt). |
| 15201 | That Queen Anne is dead is a 'general fact', not a fact about Queen Anne [Prior,AN] |
| Full Idea: The fact that Queen Anne has been dead for some years is not, in the strict sense of 'about', a fact about Queen Anne; it is not a fact about anyone or anything - it is a general fact. | |
| From: Arthur N. Prior (Changes in Events and Changes in Things [1968], p.13), quoted by Robin Le Poidevin - Past, Present and Future of Debate about Tense 1 b | |
| A reaction: He distinguishes 'general facts' (states of affairs, I think) from 'individual facts', involving some specific object. General facts seem to be what are expressed by negative existential truths, such as 'there is no Loch Ness Monster'. Useful. |
| 18888 | Essentialism says some properties must be possessed, if a thing is to exist [Salmon,N] |
| Full Idea: The metaphysical doctrine of essentialism says that certain properties of things are properties that those things could not fail to have, except by not existing. | |
| From: Nathan Salmon (Reference and Essence (1st edn) [1981], 3.8.2) | |
| A reaction: A bad account of essentialism, and a long way from Aristotle. It arises from the logicians' tendency to fix objects entirely in terms of a 'flat' list of predicates (called 'properties'!), which ignore structure, constitution, history etc. |
| 18886 | Frege's 'sense' solves four tricky puzzles [Salmon,N] |
| Full Idea: Reference via sense solves Frege's four puzzles, of the informativeness of identity statements, the failure of substitutivity in attitude contexts, of negative existentials, and the truth-value of statements using nondenoting singular terms. | |
| From: Nathan Salmon (Reference and Essence (1st edn) [1981], 1.1.1) | |
| A reaction: These must then be compared with Kripke's three puzzles about referring via sense, and the whole debate is then spread before us. |
| 18887 | The perfect case of direct reference is a variable which has been assigned a value [Salmon,N] |
| Full Idea: The paradigm of a nondescriptional, directly referential, singular term is an individual variable. …The denotation of a variable… is semantically determined directly by the assignment of values. | |
| From: Nathan Salmon (Reference and Essence (1st edn) [1981], 1.1.2) | |
| A reaction: This cuts both ways. Maybe we are muddling ordinary reference with the simplicities of logical assignments, or maybe we make logical assignments because that is the natural way our linguistic thinking works. |
| 23169 | Democratic institutions become impossible in a fanatical democracy [Russell] |
| Full Idea: Even democracy, when it becomes fanatical, as it did …in the French Revolution, ceases to be Liberal. Indeed, a fanatical belief in democracy makes democratic institutions impossible. | |
| From: Bertrand Russell (Philosophy and Politics [1950], p.26) | |
| A reaction: Presumably this is because the supposed 'will of the people' is continually placed in opposition to the institutions. For example, there is a problem if a referendum is held, which produces a result in conflict with the institutions. |
| 23170 | Liberal opinions are tentative rather than dogmatic, and are always responsive to new evidence [Russell] |
| Full Idea: The essence of the Liberal outlook lies ...in how opinions are held: instead of being held dogmatically, they are held tentatively (as they are in science), and with a consciousness that new evidence may at any moment lead to their abandonment. | |
| From: Bertrand Russell (Philosophy and Politics [1950], p.26) | |
| A reaction: A nice assessment. Russell shows himself finally to be a Liberal. This flexible approach to opinions is what infuriates dogmatists from both the left and the right. It might be said that the basic evidence rarely changes. |
| 23172 | Empiricist Liberalism is the only view for someone who favours scientific evidence and happiness [Russell] |
| Full Idea: Empiricist Liberalism (not incompatible with democratic socialism) is, as in Locke's time, the only philosophy that can be adopted by a man who demands some scientific evidence for beliefs, and also desires human happiness more than some party or creed. | |
| From: Bertrand Russell (Philosophy and Politics [1950], p.31) | |
| A reaction: I like this way of presenting liberalism. In the modern world we are sunk if we don't pay attention to experts, so we all need a critical understanding of what counts as good evidence. Tricky in a world of lying media. |
| 23171 | Empiricism is ethically superior, because dogmatism favours persecution and hatred [Russell] |
| Full Idea: Empiricism is to be commended not only on the grounds of its greater truth, but also on ethical grounds. Dogma demands authority rather than intelligent thought; it requires persecution of heretics and unbelievers, and favours systematic hatred. | |
| From: Bertrand Russell (Philosophy and Politics [1950], p.31) | |
| A reaction: He links empiricism with the liberal outlook. At its best, the respect by empiricists for evidence is a sort of humility. |
| 18891 | Nothing in the direct theory of reference blocks anti-essentialism; water structure might have been different [Salmon,N] |
| Full Idea: There seems to be nothing in the theory of direct reference to block the anti-essentialist assertion that the substance water might have been the very same entity and yet have had a different chemical structure. | |
| From: Nathan Salmon (Reference and Essence (1st edn) [1981], 6.23.1) | |
| A reaction: Indeed, water could be continuously changing its inner structure, while retaining the surface appearance that gets baptised as 'water'. We make the reasonable empirical assumption, though, that structure-change implies surface-change. |
| 22899 | 'Thank goodness that's over' is not like 'thank goodness that happened on Friday' [Prior,AN] |
| Full Idea: One says 'thank goodness that is over', ..and it says something which it is impossible which any use of any tenseless copula with a date should convey. It certainly doesn't mean the same as 'thank goodness that occured on Friday June 15th 1954'. | |
| From: Arthur N. Prior (Changes in Events and Changes in Things [1968]), quoted by Adrian Bardon - Brief History of the Philosophy of Time 4 'Pervasive' | |
| A reaction: [Ref uncertain] This seems to be appealing to ordinary usage, in which tenses have huge significance. If we take time (with its past, present and future) as primitive, then tenses can have full weight. Did tenses mean anything at all to Einstein? |
