| 6979 | Serious metaphysics cares about entailment between sentences [Jackson] |
| Full Idea: Serious metaphysics is committed to views about which sentences entail which other sentences. | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.1) | |
| A reaction: This does not say that metaphysics is only about entailment, or (even worse) only about sentences. Put another way: if we wish to be wise, we must study the implications of our beliefs. Yes. |
| 6980 | Conceptual analysis studies whether one story is made true by another story [Jackson] |
| Full Idea: Conceptual analysis is the very business of addressing when and whether a story told in one vocabulary is made true by one told in some allegedly more fundamental vocabulary. | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.2) | |
| A reaction: This is a view of linguistic analysis as focusing on entailments rather than on usage or truth conditions. If philosophy is the attempt to acquire a totally consistent set of beliefs (a plausible view), then Jackson is right. |
| 6983 | Intuitions about possibilities are basic to conceptual analysis [Jackson] |
| Full Idea: Intuitions about possibilities are the bread and butter of conceptual analysis. | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.3) | |
| A reaction: Hence the centrality of the debate over conceivability and possibility. Which seems to reduce to the relationship between 'intuition' and 'imagination'. Imagination is a very weak guide to what is possible, and intuition is very uncertain.... |
| 14707 | Conceptual analysis is needed to establish that metaphysical reductions respect original meanings [Jackson, by Schroeter] |
| Full Idea: On the empiricist view of meaning, the relevance of conceptual analysis to metaphysics is that it establishes that a putative reduction respects the original meaning of the target expression. | |
| From: report of Frank Jackson (From Metaphysics to Ethics [1998], p.28) by Laura Schroeter - Two-Dimensional Semantics 2.2.4 |
| 7005 | Something can only have a place in a preferred account of things if it is entailed by the account [Jackson] |
| Full Idea: The one and only way of having a place in an account told in some set of preferred terms is by being entailed by that account - a view I will refer to as the entry by entailment thesis. | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.1) | |
| A reaction: How do we distinguish between the original account, which seems to be just accepted, and the additions which accrue because they are entailed by it? Why does this club distinguish members from guests? |
| 6994 | Truth supervenes on being [Jackson] |
| Full Idea: Truth supervenes on being. | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.5) | |
| A reaction: A nice slogan for those of us who find the word 'truth' to be meaningful. |
| 21495 | Theoretical and practical politics are both concerned with the best lives for individuals [Russell] |
| Full Idea: Political ideals must be based upon ideals for the individual life. The aim of politics should be to make the lives of individuals as good as possible. | |
| From: Bertrand Russell (Political Ideals [1917], 1) | |
| A reaction: Russell floats between socialism and anarchism, but this foundational remark is classic liberalism. |
| 6984 | Smooth reductions preserve high-level laws in the lower level [Jackson] |
| Full Idea: In a 'smooth' reduction the laws of the reduced theory (thermodynamics of gases) are pretty much preserved in (and isomorphic with) the corresponding laws in the reducing theory (molecular or kinetic theory of gases). | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.3) | |
| A reaction: Are the 'laws' of weather (e.g. linking humidity, temperature and pressure to rainfall) preserved at the level of physics? One might say that they are not preserved, but they are not lost either (they just fade away). Contradictions would be worrying. |
| 6978 | Baldness is just hair distribution, but the former is indeterminate, unlike the latter [Jackson] |
| Full Idea: Baldness is a much more indeterminate matter than is hair distribution, nevetheless baldness is nothing over and above hair distribution. | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], p.22) | |
| A reaction: This seems to support Williamson's view that there is no vagueness in nature, and that 'vague' is an entirely epistemological concept. |
| 6993 | Redness is a property, but only as a presentation to normal humans [Jackson] |
| Full Idea: We typically count things as red just if they have a property that interacts with normal human beings to make the object look red in such a way that their so looking counts as a presentation of the property to normal humans. | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.4) | |
| A reaction: This is Jackson's careful statement of the 'Australian' primary property view of colours. He is trying to make red a real property of objects, but personally I take the mention of 'normal' humans as a huge danger sign. Nice try, but no. See Idea 5456. |
| 6987 | We should not multiply senses of necessity beyond necessity [Jackson] |
| Full Idea: We should not multiply senses of necessity beyond necessity. | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.3) | |
| A reaction: It would be nice if there was just one sense of necessity, with the multiplication arising from the different ways in which necessities arise. In chess, checkmate is a necessity which rests on contingencies. Absolute necessities seem different. |
| 6988 | Mathematical sentences are a problem in a possible-worlds framework [Jackson] |
| Full Idea: There is notoriously a problem about what to say concerning mathematical sentences within the possible-worlds framework. | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.3 n25) | |
| A reaction: Presumably this concerns possible axioms and their combinations. |
| 6975 | Possible worlds could be concrete, abstract, universals, sentences, or properties [Jackson] |
| Full Idea: Possible worlds might be concrete (Lewis), or abstract (Stalnaker), or structured universals (Forrest), or collections of sentences (Jeffrey), or mere combinations of properties and relations (Armstrong). | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.1) | |
| A reaction: A helpful summary. I don't like concrete, or collections of sentences. Whatever they are, they had better be 'possible', so not any old collection or idea will do. |
| 6982 | Long arithmetic calculations show the a priori can be fallible [Jackson] |
| Full Idea: We know that being fallible and being a priori can co-exist - the results of long numerical additions are well-known examples. | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.2) | |
| A reaction: I see this realisation as a good example of progress in philosophy. Russell, who says self-evidence comes in degrees, deserves major credit. It is the key idea that once again makes rationalism respectable. |
| 6991 | We examine objects to determine colour; we do not introspect [Jackson] |
| Full Idea: We examine objects to determine their colour; we do not introspect. | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.3) | |
| A reaction: Interesting, but the theory of secondary qualities did not arise from experience, but from a theory about what is actually going on. Compare pain appearing to be in your foot. |
| 6976 | In physicalism, the psychological depends on the physical, not the other way around [Jackson] |
| Full Idea: Physicalism is associated with various asymmetry doctrines, most famously with the idea that the psychological depends in some sense on the physical, and not the other way around. | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.1) | |
| A reaction: Sounds okay to me. Shadows depend on objects, and not the other way round. It might suggest properties depending on substances (or bare particulars), but I prefer the dependence of processes on mechanisms (waterfalls on liquid water). |
| 6986 | Is the dependence of the psychological on the physical a priori or a posteriori? [Jackson] |
| Full Idea: Should the necessary passage from the physical account of the world to the psychological one that physicalists are committed to, be placed in the a posteriori or the a priori basket? | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.3) | |
| A reaction: That is, is 'the physical entails the mental' empirical or a priori? See Idea 3989. If we can at least dream of substance dualism, it is hard to see how it could be fully a priori. I think I prefer to see it as an inductive explanation. |
| 6992 | If different states can fulfil the same role, the converse must also be possible [Jackson] |
| Full Idea: It would be strange if having learnt the lesson of multiple realisability that the same role may be filled by different states, we turned around and insisted that the converse - different roles filled by the same state - is impossible. | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.4 n3) | |
| A reaction: Good. The world is full of creatures who seem to enjoy the smell of decay etc. Some people (not me) like horror films. The separation of qualia and role leaves type-type physicalism as a possibility. Survival needs similar roles, not similar qualia. |
| 6996 | Folk psychology covers input, internal role, and output [Jackson] |
| Full Idea: Folk psychology has a tripartite nature, with input clauses, internal role clauses, and output clauses. | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.5) | |
| A reaction: Interesting, particularly that folk psychology refers to internal roles, or attempts to explain what is going on inside the 'black box'. The folk have collectively worked out a standard flow diagram for human thought. |
| 6977 | Egocentric or de se content seems to be irreducibly so [Jackson] |
| Full Idea: I have been convinced by arguments (e.g. of Perry, Castaņeda and Lewis) that egocentric or de se content is irreducibly so. | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.1) | |
| A reaction: This is associated with the use of indexicals (like 'I' and 'now') in language. Quine disagrees, and should not be written off. Any theory of content, concepts, meaning etc. must clearly taken account of such subjective language. |
| 6990 | Keep distinct the essential properties of water, and application conditions for the word 'water' [Jackson] |
| Full Idea: My guess is that objectors to the deflationary account of the Twin Earth parable are confusing the essential properties of water with the question of what is essential for being water. | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.3) | |
| A reaction: That is, we must distinguish between the actual ontology of water's properties and the conditions under which we (in our society) apply the word 'water'. Interesting. The latter issue, though, might push us back towards internalism... |
| 6985 | Analysis is finding necessary and sufficient conditions by studying possible cases [Jackson] |
| Full Idea: Conceptual analysis is sometimes understood as the business of finding necessary and sufficient conditions by the method of possible cases. | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.3) | |
| A reaction: Some (e.g. Stich) reject this, but it seems to me undeniable that the procedure can be very illuminating, even if it is never totally successful. Jackson prefers to see analysis as the study of entailments between stories about the world. |
| 6995 | Successful predication supervenes on nature [Jackson] |
| Full Idea: Successful predication supervenes on nature. | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.5) | |
| A reaction: A nice slogan, but it is in danger of being a tautology. If I say x and y 'are my favourites/are interesting', is that 'successful' predication? Is 'Juliet is the sun' unsuccessful? |
| 6989 | I can understand "He has a beard", without identifying 'he', and hence the truth conditions [Jackson] |
| Full Idea: If I hear someone say "He has a beard", and I don't know whether it is Jackson, Jones, or someone else, I don't know which proposition is being expressed in the sense of not knowing the conditions under which what is said is true. | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.3) | |
| A reaction: This is the neatest and simplest problem I have encountered for Davidson's truth-conditions account of meaning. However, we probably just say that we understand the sense but not the reference. The strict-and-literal but not contextual meaning. |
| 6998 | Folk morality does not clearly distinguish between doing and allowing [Jackson] |
| Full Idea: We have, it seems to me, currently no clear sense of the place and rationale of the distinction between doing and allowing in folk morality. | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.5) | |
| A reaction: Does this mean that philosophers should endeavour to appear on television in order to improve folk morality, so that Jackson, back at the ranch, can then infer the meanings of moral terms from the new improved version? |
| 6997 | Moral functionalism says moral terms get their meaning from their role in folk morality [Jackson] |
| Full Idea: Moral functionalism is the view that the meanings of moral terms are given by their place in the network of input, internal clauses, and output that makes up folk psychology. | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.5) | |
| A reaction: Jackson considers this enough to support a cognitivist view of morality. In assuming that there is something stable called 'folk morality' he seems to be ignoring questions about cultural relativism. |
| 7000 | Which are prior - thin concepts like right, good, ought; or thick concepts like kindness, equity etc.? [Jackson] |
| Full Idea: 'Centralists' (e.g. Bernard Williams) say thin ethical concepts (right, good, ought) are conceptually fundamental; 'non-centralists' (e.g. Susan Hurley) say that such concepts are not conceptually prior to kindness, equity and the like. | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.5) | |
| A reaction: My immediate intuition is to side with Susan Hurley, since morality grows out of immediate relationships, not out of intellectual principles and theoretical generalisations. This would go with particularist views of virtue theory. |
| 16764 | The soul conserves the body, as we see by its dissolution when the soul leaves [Toletus] |
| Full Idea: Every accident of a living thing, as well as all its organs and temperaments and its dispositions are conserved by the soul. We see this from experience, since when that soul recedes, all these dissolve and become corrupted. | |
| From: Franciscus Toletus (Commentary on 'De Anima' [1572], II.1.1), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 24.5 | |
| A reaction: A nice example of observing a phenemonon, but not being able to observe the dependence relation the right way round. Compare Descartes in Idea 16763. |
| 21517 | Individuals need creativity, reverence for others, and self-respect [Russell] |
| Full Idea: What we shall desire for individuals is now clear: strong creative impulses, overpowering and absorbing the instinct of possession; reverence for others; respect for the fundamental creative impulses in ourselves. | |
| From: Bertrand Russell (Political Ideals [1917], 1) | |
| A reaction: Interesting that when Russell focuses on morality, he turns to virtues, rather than to rules. He uses 'reverence' where I would favour 'respect'. His concept of creativity is broad, and does not just concern art etc. |
| 21523 | We would not want UK affairs to be settled by a world parliament [Russell] |
| Full Idea: We should none of us like the affairs of Great Britain to be settled by a parliament of the world. | |
| From: Bertrand Russell (Political Ideals [1917], 1) | |
| A reaction: The UK is currently (Dec 2018) living with a plan to quit Europe, mainly on the grounds that a European parliament has some authority over Britain. In every country resentment of the government increases with distance from the capital city. |
| 21522 | Democracy is inadequate without a great deal of devolution [Russell] |
| Full Idea: Democracy is not at all an adequate device unless it is accompanied by a very great amount of devolution. | |
| From: Bertrand Russell (Political Ideals [1917], 1) | |
| A reaction: This whole book of Russell's is an appeal for the devolution of power, and for workplace democracy. |
| 21521 | Anarchy does not maximise liberty [Russell] |
| Full Idea: The greatest degree of liberty is not secured by anarchy. ...[22] The results of anarchy between states should suffice to persuade us that anarchism has no solution to offer for the evils of the world. | |
| From: Bertrand Russell (Political Ideals [1917], 1) | |
| A reaction: I've heard Russell described as an anarchist, but this clearly wasn't true in 1917. Presumably liberty has to be protected. That we were watching anarchy between states in 1917 is a vivid observation. |
| 21528 | Groups should be autonomous, with a neutral authority as arbitrator [Russell] |
| Full Idea: For maximum freedom with minimum force: Autonomy within each politically important group, and a neutral authority for deciding questions involving relations between groups. | |
| From: Bertrand Russell (Political Ideals [1917], 3) | |
| A reaction: This is workplace democracy, and also considerable self-rule amongst minority groups such as religions. |
| 21527 | On every new question the majority is always wrong at first [Russell] |
| Full Idea: It is a mistake to suppose that the majority is necessarily right. On every new question the majority is always wrong at first. | |
| From: Bertrand Russell (Political Ideals [1917], 3) | |
| A reaction: Sounds like bitter experience. This is a good argument for taking time over decisions, and (topical) for a second referendum some time after the first one (if you must have a referendum). |
| 21526 | Unfortunately ordinary voters can't detect insincerity [Russell] |
| Full Idea: It is a painful fact that the ordinary voter, at any rate in England, is quite blind to insincerity. | |
| From: Bertrand Russell (Political Ideals [1917], 3) | |
| A reaction: Gor blimey yes! Well said, Bertie. Even in the age of television, when you can examine them in closeup, people seem to confuse superficial charm with genuine positive convictions. Why are people better at detecting it in private life? |
| 21525 | When the state is the only employer, there is no refuge from the prejudices of other people [Russell] |
| Full Idea: Under state socialism ...where the State is the only employer, there is no refuge from its prejudices such as may now accidentally arise through the differing opinions of men. | |
| From: Bertrand Russell (Political Ideals [1917], 2) | |
| A reaction: There is also a strong likelihood in full state socialism that the state will control housing as well as employment. This hadn't come to pass in 1917. |
| 21518 | Men unite in pursuit of material things, and idealise greed as part of group loyalty [Russell] |
| Full Idea: Men combine in groups to attain more strength in the scramble for material goods, and loyalty to the group spreads a halo of quasi-idealism round the central impulse of greed. | |
| From: Bertrand Russell (Political Ideals [1917], 1) | |
| A reaction: See the 'greed is good' speech in the film 'Wall Street'. This sounds like a description of the USA, but Russell was very much in England at this stage. |
| 21519 | We need security and liberty, and then encouragement of creativity [Russell] |
| Full Idea: Security and liberty are only the negative conditions for good political institutions. When they have been won, we need also the positive condition: encouragement of creative energy. | |
| From: Bertrand Russell (Political Ideals [1917], 1) | |
| A reaction: This sounds like some sort of liberal socialism. The nearest connection I can see is to the 'capabilities approach' of Martha Nussbaum. How do you intervene to encourage creativity? |
| 21524 | The right to own land gives a legal right to a permanent income [Russell] |
| Full Idea: There are many ways of becoming rich without contributing anything to the wealth of the community. Ownership of land or capital, whether acquired or inherited, gives a legal right to a permanent income. | |
| From: Bertrand Russell (Political Ideals [1917], 2) | |
| A reaction: I suspect that in the past land was the main source of this right, but now it is more likely to be capital. Land carries obligations of some sort, so income from capital is more fun. |
| 6999 | It is hard to justify the huge difference in our judgements of abortion and infanticide [Jackson] |
| Full Idea: We allow that abortion is permissible in many circumstances, but infanticide is hardly ever permissible, and yet it is hard to justify this disparity in moral judgement in the sense of finding the relevant difference. | |
| From: Frank Jackson (From Metaphysics to Ethics [1998], Ch.5) | |
| A reaction: The implications of this are tough to face. A foetus is (maybe) just not as important as a new-born babe - and so a new-born babe is of less importance than a five-year old. Birth is (or was) a hugely dangerous hurdle to be cleared. |
| 21520 | That our heaven is a dull place reflects the misery of excessive work in life [Russell] |
| Full Idea: It is a sad evidence of the weariness mankind has suffered from excessive toil that his heavens have usually been places where nothing ever happened or changed. | |
| From: Bertrand Russell (Political Ideals [1917], 1) | |
| A reaction: Has any religion got an idea of heaven as a place full of lively activity and creative problem-solving? That is what suits us best. |
