| 14092 | Philosophers are often too fussy about words, dismissing perfectly useful ordinary terms [Rosen] |
| Full Idea: Philosophers can sometimes be too fussy about the words they use, dismissing as 'unintelligible' or 'obscure' certain forms of language that are perfectly meaningful by ordinary standards, and which may be of some real use. | |
| From: Gideon Rosen (Metaphysical Dependence [2010], 01) | |
| A reaction: Analytic philosophers are inclined to drop terms they can't formalise, but there is more to every concept than its formalisation (Frege's 'direction' for example). I want to rescue 'abstraction' and 'essence'. Rosen says distinguish, don't formalise. |
| 14100 | Figuring in the definition of a thing doesn't make it a part of that thing [Rosen] |
| Full Idea: From the simple fact that '1' figures in the definition of '2', it does not follow that 1 is part of 2. | |
| From: Gideon Rosen (Metaphysical Dependence [2010], 10) | |
| A reaction: He observes that quite independent things can be mentioned on the two sides of a definition, with no parthood relation. You begin to wonder what a definition really is. A causal chain? |
| 14096 | Explanations fail to be monotonic [Rosen] |
| Full Idea: The failure of monotonicity is a general feature of explanatory relations. | |
| From: Gideon Rosen (Metaphysical Dependence [2010], 05) | |
| A reaction: In other words, explanations can always shift in the light of new evidence. In principle this is right, but some explanations just seem permanent, like plate-tectonics as explanation for earthquakes. |
| 14097 | Things could be true 'in virtue of' others as relations between truths, or between truths and items [Rosen] |
| Full Idea: Our relation of 'in virtue of' is among facts or truths, whereas Fine's relation (if it is a relation at all) is a relation between a given truth and items whose natures ground that truth. | |
| From: Gideon Rosen (Metaphysical Dependence [2010], 07 n10) | |
| A reaction: This disagreement between two key players in the current debate on grounding looks rather significant. I think I favour Fine's view, as it seems more naturalistic, and less likely to succumb to conventionalism. |
| 14095 | Facts are structures of worldly items, rather like sentences, individuated by their ingredients [Rosen] |
| Full Idea: Facts are structured entities built up from worldly items rather as sentences are built up from words. They might be identified with Russellian propositions. They are individuated by their constituents and composition, and are fine-grained. | |
| From: Gideon Rosen (Metaphysical Dependence [2010], 04) | |
| A reaction: I'm a little cautious about the emphasis on being sentence-like. We have Russell's continual warnings against imposing subject-predicate structure on things. I think we should happily talk about 'facts' in metaphysics. |
| 14093 | An 'intrinsic' property is one that depends on a thing and its parts, and not on its relations [Rosen] |
| Full Idea: One intuitive gloss on 'intrinsic' property is that a property is intrinsic iff whether or not a thing has it depends entirely on how things stand with it and its parts, and not on its relation to some distinct thing. | |
| From: Gideon Rosen (Metaphysical Dependence [2010], 02) | |
| A reaction: He offers this as a useful reward for reviving 'depends on' in metaphysical talk. The problem here would be to explain the 'thing' and its 'parts' without mentioning the target property. The thing certainly can't be a bundle of tropes. |
| 14094 | The excellent notion of metaphysical 'necessity' cannot be defined [Rosen] |
| Full Idea: Many of our best words in philosophy do not admit of definition, the notion of metaphysical 'necessity' being one pertinent example. | |
| From: Gideon Rosen (Metaphysical Dependence [2010], 03) | |
| A reaction: Rosen is busy defending words in metaphysics which cannot be pinned down with logical rigour. We are allowed to write □ for 'necessary', and it is accepted by logicians as being stable in a language. |
| 14101 | Are necessary truths rooted in essences, or also in basic grounding laws? [Rosen] |
| Full Idea: Fine says a truth is necessary when it is a logical consequence of the essential truths, but maybe it is a consequence of the essential truths together with the basic grounding laws (the 'Moorean connections'). | |
| From: Gideon Rosen (Metaphysical Dependence [2010], 13) | |
| A reaction: I'm with Fine all the way here, as we really don't need to clog nature up with things called 'grounding laws', which are both obscure and inexplicable. Fine's story is the one for naturalistically inclined philosophers. |
| 14099 | 'Bachelor' consists in or reduces to 'unmarried' male, but not the other way around [Rosen] |
| Full Idea: It sounds right to say that Fred's being a bachelor consists in (reduces to) being an unmarried male, but slightly off to say that Fred's being an unmarried male consists in (or reduces to) being a bachelor. There is a corresponding explanatory asymmetry. | |
| From: Gideon Rosen (Metaphysical Dependence [2010], 10) | |
| A reaction: This emerging understanding of the asymmetry of the idea shows that we are not just dealing with a simple semantic identity. Our concepts are richer than our language. He adds that a ball could be blue in virtue of being cerulean. |
| 468 | Musical performance can reveal a range of virtues [Damon of Ath.] |
| Full Idea: In singing and playing the lyre, a boy will be likely to reveal not only courage and moderation, but also justice. | |
| From: Damon (fragments/reports [c.460 BCE], B4), quoted by (who?) - where? |
| 22808 | Liberalism is minimal government, or individual rights, or equality [Avineri/De-Shalit] |
| Full Idea: Liberalism has been defended as a theory of minimal government, or as a theory of basic individual rights, or as an egalitarian philosophy. | |
| From: Avineri,S/De-Shalit,A (Intro to 'Communitarianism and Individualism' [1992], §5) | |
| A reaction: Minimal government tends towards anarchist liberalism, but then what grounds the right to be free of government? Presumably any sensible theory of rights has to be egalitarian. What could ground unequal rights? |
| 22803 | Can individualist theories justify an obligation to fight in a war? [Avineri/De-Shalit] |
| Full Idea: How can an individualist theory justify an obligation to fight for the state in the case of war? | |
| From: Avineri,S/De-Shalit,A (Intro to 'Communitarianism and Individualism' [1992], §4) | |
| A reaction: The most dramatic example of obliging citizens to contribute to the state, the notable other case being taxes. Some imagined ancient 'social contract' doesn't seem sufficient for later generations. Does being naturally sociable create such obligations? |
| 22804 | Autonomy is better achieved within a community [Avineri/De-Shalit] |
| Full Idea: Communitarians often argue that personal autonomy is better achieved within the community. | |
| From: Avineri,S/De-Shalit,A (Intro to 'Communitarianism and Individualism' [1992], §4) | |
| A reaction: Hegel is the source of this view. The simplest version of the point is that autonomy can only be asserted if a person has rights, which can be asserted and defended, and only a society can provide that. That is plausible. |
| 22806 | Communitarians avoid oppression for the common good, by means of small mediating communities [Avineri/De-Shalit] |
| Full Idea: Because of the mediating structures of small communities, communitarians are less fearful [than liberals] of the emergence of an oppressive government as a result of the politics of the common good. | |
| From: Avineri,S/De-Shalit,A (Intro to 'Communitarianism and Individualism' [1992], §5) | |
| A reaction: A politics of the common good has an obvious implicit conservatism because the central consensus is always likely to disapprove of errant individuals, of all sorts. Only individual rights can block an oppressive government. |
| 22807 | If our values are given to us by society then we have no grounds to criticise them [Avineri/De-Shalit] |
| Full Idea: If communitarians are right that we are not free to choose, but rather that our values are determined by our community, the individualists say, then there is no reason to criticise the values of one's society. | |
| From: Avineri,S/De-Shalit,A (Intro to 'Communitarianism and Individualism' [1992], §5) | |
| A reaction: This is an obvious challenge, but if one's concept of community is a forum for free debate then it can be overcome. There is no avoiding the fact, though, that a good community always needs a high degree of consensus. |
| 14098 | An acid is just a proton donor [Rosen] |
| Full Idea: To be an acid just is to be a proton donor. | |
| From: Gideon Rosen (Metaphysical Dependence [2010], 10) | |
| A reaction: My interest here is in whether we can say that we have found the 'essence' of an acid - so we want to know whether something 'deeper' explains the proton-donation. I suspect not. Being a proton donor happens to have a group of related consequences. |
