| 12667 | Metaphysics aims at the simplest explanation, without regard to testability [Ellis] |
| Full Idea: The methodology of metaphysics... is that of arguing to the simplest explanation, without regard to testability. | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 1) | |
| A reaction: I love that! I'd be a bit cautious about 'simplest', since 'everything is the output of an ineffable God' is beautifully simple, and brings the whole discussion to a halt. I certainly think metaphysics goes deeper than testing. String Theory? |
| 12666 | We can base logic on acceptability, and abandon the Fregean account by truth-preservation [Ellis] |
| Full Idea: In logic, acceptability conditions can replace truth conditions, ..and the only price one has to pay for this is that one has to abandon the implausible Fregean idea that logic is the theory of truth preservation. | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 1) | |
| A reaction: This has always struck me as correct, given that if you assign T and F in a semantics, they don't have to mean 'true' and 'false', and that you can do very good logic with propositions which you think are entirely false. |
| 12688 | Mathematics is the formal study of the categorical dimensions of things [Ellis] |
| Full Idea: I wish to explore the idea that mathematics is the formal study of the categorical dimensions of things. | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 6) | |
| A reaction: Categorical dimensions are spatiotemporal relations and other non-causal properties. Ellis defends categorical properties as an aspect of science. The obvious connection seems to be with structuralism in mathematics. Shapiro is sympathetic. |
| 12683 | Objects and substances are a subcategory of the natural kinds of processes [Ellis] |
| Full Idea: The category of natural kinds of objects or substances should be regarded simply as a subcategory of the category of the natural kinds of processes. | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 3) | |
| A reaction: This is a new, and interesting, proposal from Ellis (which will be ignored by the philosophical community, as all new theories coming from elderly philosophers are ignored! Cf Idea 12652). A good knowledge of physics is behind Ellis's claim. |
| 12670 | A physical event is any change of distribution of energy [Ellis] |
| Full Idea: We may define a physical event as any change of distribution of energy in any of its forms. | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 2) | |
| A reaction: This seems to result in an awful lot of events. My own (new this morning) definition is: 'An event is a process which can be individuated in time'. Now you just have to work out what a 'process' is, but that's easier than understanding an 'event'. |
| 12673 | Physical properties are those relevant to how a physical system might act [Ellis] |
| Full Idea: We may define a physical property as one whose value is relevant, in some circumstances, to how a physical system is likely to act. | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 2) | |
| A reaction: Fair enough, but can we use the same 'word' property when we are discussing abstractions? Does 'The Enlightenment' have properties? Do very simple things have properties? Can 'red' act, if it isn't part of any physical system? |
| 12665 | I support categorical properties, although most people only want causal powers [Ellis] |
| Full Idea: I want to insist on the existence of a class of categorical properties distinct from causal powers. This is contentious, for there is a growing body of opinion that all properties are causal powers. | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], Intro) | |
| A reaction: Alexander Bird makes a case against categorical properties. If what is meant is that 'being an electron' is the key property of an electron, then I disagree (quite strongly) with Ellis. Ellis says they are needed to explain causal powers. |
| 12682 | Essentialism needs categorical properties (spatiotemporal and numerical relations) and dispositions [Ellis] |
| Full Idea: Essentialist metaphysics seem to require that there be at least two kinds of properties in nature: dispositional properties (causal powers, capacities and propensities), and categorical ones (spatiotemporal and numerical relations). | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 3) | |
| A reaction: At last someone tells us what a 'categorical' property is! Couldn't find it in Stanford! Bird and Molnar reject the categorical ones as true properties. If there are six cats, which cat has the property of being six? Which cat is 'three metres apart'? |
| 12684 | Spatial, temporal and numerical relations have causal roles, without being causal [Ellis] |
| Full Idea: Spatial, temporal and numerical relations can have various causal roles without themselves being instances of causal powers. | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 3) | |
| A reaction: He cites gaps, aggregates, orientations, approaching and receding, as examples of categorical properties which make a causal difference. I would have thought these could be incorporated in accounts of more basic causal powers. |
| 12672 | Properties and relations are discovered, so they can't be mere sets of individuals [Ellis] |
| Full Idea: To regard properties as sets of individuals, and relations as sets of ordered individuals, is to make a nonsense of the whole idea of discovering a new property or relationship. Sets are defined or constructed, not discovered. | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 2) | |
| A reaction: This bizarre view of properties (as sets) drives me crazy, until it dawns on you that they are just using the word 'property' in a different way, probably coextensively with 'predicate', in order to make the logic work. |
| 12676 | Causal powers can't rest on things which lack causal power [Ellis] |
| Full Idea: A causal power can never be dependent on anything that does not have any causal powers. | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 3) | |
| A reaction: Sounds right, though you worry when philosophers make such bold assertions about such extreme generalities. But see Idea 12667. This is, of course, the key argument for saying that causal powers are the bedrock of reality, and of explanation. |
| 23781 | Categoricals exist to influence powers. Such as structures, orientations and magnitudes [Ellis, by Williams,NE] |
| Full Idea: Ellis allows categoricals alongside powers, …to influence the sort of manifestations produced by powers. He lists structures, arrangements, distances, orientations, and magnitudes. | |
| From: report of Brian Ellis (The Metaphysics of Scientific Realism [2009]) by Neil E. Williams - The Powers Metaphysics 05.2 | |
| A reaction: I would have thought that all of these could be understood as manifestations of powers. The odd one out is distances, but then space and time are commonly overlooked in every attempt to produce a complete ontology. [also Molnar 2003:164]. |
| 12686 | Causal powers are a proper subset of the dispositional properties [Ellis] |
| Full Idea: The causal powers are just a proper subset of the dispositional properties. | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 5) | |
| A reaction: Sounds wrong. Causal powers have a physical reality, while a disposition sounds as if it can wholly described by a counterfactual claim. It seems better to say that things have dispositions because they have powers. |
| 12685 | Categorical properties depend only on the structures they represent [Ellis] |
| Full Idea: I would define categorical properties as those whose identities depend only on the kinds of structures they represent. | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 3 n8) | |
| A reaction: Aha. So categorical properties would be much more perspicaciously labelled as 'structural' properties. Why does philosophical terminology make it all more difficult than it needs to be? |
| 12679 | A real essence is a kind's distinctive properties [Ellis] |
| Full Idea: A distinctive set of intrinsic properties for a given kind is called a 'real essence'. | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 3) | |
| A reaction: Note that he thinks essence is a set of properties (rather than what gives rise to the properties), and that it is kinds (and not individuals) which have real essences, and that one role of the properties is to be 'distinctive' of the kind. Cf. Oderberg. |
| 12668 | Metaphysical necessity holds between things in the world and things they make true [Ellis] |
| Full Idea: Metaphysical necessitation is the relation that holds between things in the world and the things they make true. | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 1) | |
| A reaction: Not sure about that. It implies that it is sentences that have necessity, and he confirms it by calling it 'a semantic relation'. So there are no necessities if there are no sentences? Not the Brian Ellis we know and love. |
| 12687 | Metaphysical necessities are those depending on the essential nature of things [Ellis] |
| Full Idea: A metaphysically necessary proposition is one that is true in virtue of the essential nature of things. | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 6) | |
| A reaction: It take this to be what Kit Fine argues for, though it tracks back to Aristotle. I also take it to be correct, though one might ask whether there are any other metaphysical necessities, ones not depending on essences. |
| 12669 | Science aims to explain things, not just describe them [Ellis] |
| Full Idea: The primary aim of science is to explain what happens, not just to describe it. | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 2) | |
| A reaction: This I take to be a good motto for scientific essentialism. Any scientist who is happy with anything less than explanation is a mere journeyman, a servant in the kitchens of the great house of science. |
| 18658 | The 'Kantian' self steps back from commitment to its social situation [Kymlicka] |
| Full Idea: The 'Kantian' view of the self strongly defends the view that the self is prior to its socially given roles and relationships, and is free only if it is capable of holding these features of its social situation at a distance, and judging them by reason. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 6.3) | |
| A reaction: There is no correct answer here, because I am capable of Kantian distancing, and also capable of submersing myself in the social constructions around me. If society fosters rebellion (1810s, 1960s) then we become more Kantian. |
| 18650 | Teleological theories give the good priority over concern for people [Kymlicka] |
| Full Idea: Teleological theories take concern for the good (e.g. freedom or utility) as fundamental, and concern for people as derivative. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 2.4.a.ii) | |
| A reaction: There's a nice fundamental question with which to begin a discussion of value: which matters most - abstract values, or individual people? Placing a collective of people first (Stalinism?) seems to fall between them. |
| 18664 | Maybe the particularist moral thought of women is better than the impartial public thinking of men [Kymlicka] |
| Full Idea: There is a significant strand of contemporary feminism which argues that we should take seriously women's different morality. ...The particularistic thought women employ is a better morality than the impartial thought men employ in the public sphere. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 7.3) | |
| A reaction: I had taken Particularism to be an offshoot of virtue theory, as promulgated by Jonathan Dancy. Evidently the influence of feminism is strong. Personally I think the world would be a better place if it was run by women. |
| 18624 | Utilitarianism is not a decision-procedure; choice of the best procedure is an open question [Kymlicka] |
| Full Idea: Utilitarianism is essentially a 'standard of rightness', not a 'decision-procedure'. ...It is an open question whether we should employ a utilitarian decision-procedure - indeed, this question itself is to be answered by examining its consequences. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 2.3.b) | |
| A reaction: The point is that the aim is to maximise happiness, and you might do that by just maximising baked bean consumption, and not even thinking about happiness. This idea is labelled 'indirect utilitarianism'. Happiness does seem to be a by-product. |
| 18626 | One view says start with equality, and infer equal weight to interests, and hence maximum utility [Kymlicka] |
| Full Idea: The first main argument for utilitarianism is that people matter equally, and hence each person's interests should be given equal weight, and hence morally right acts will maximise utility. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 2.4.a) | |
| A reaction: The point is that this starts from the aim of equality, and infers maximum utility as its consequence. Equality has a primitive value. Whenever you dig down to a primitive value in a theory, I just find myself puzzled. What can justify basic equality? |
| 18627 | A second view says start with maximising the good, implying aggregation, and hence equality [Kymlicka] |
| Full Idea: The second main argument for utilitarianism defines the right in terms of maximising the good, which leads to the utilitarian aggregation standard, which as a mere consequence treats people's interests equally. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 2.4.b) | |
| A reaction: This takes maximum good as a primitive, and arrives at equality as the way to achieve it. So which is more morally fundamental, a maximum of goodness, or human equality? Kymlicka says this idea is too impersonal. |
| 18625 | To maximise utility should we double the population, even if life somewhat deteriorates? [Kymlicka] |
| Full Idea: Morally, should we double the population, even if it means reducing each person's welfare by almost half (since that will still increase overall utility)? | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 2.4.b) | |
| A reaction: [He cites Derek Parfit for this] The key word is 'almost', which ensures a small increase in overall utility. I think this is a particularly good objection to utilitarianism, which aims to maximise an abstraction called 'utility'. |
| 18638 | The difference principles says we must subsidise the costs of other people's choices [Kymlicka] |
| Full Idea: The difference principle does not make any distinction between chosen and unchosen inequalities, ....but the difference principle requires that some people subsidise the costs of other people's choices. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 3.3.b.2) | |
| A reaction: We do this in education, allowing people to study things in which we can see little point. We subsidise public ceremonies which strike us as ridiculous. |
| 18635 | Social contract theories are usually rejected because there never was such a contract [Kymlicka] |
| Full Idea: Social contract theories have all been subjected to the same criticism - that there never was such a state of nature, or such a contract. Hence neither citizens nor government are bound by it. Contracts only create obligations if they are actually agreed. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 3.3) | |
| A reaction: Even if they have been agreed in the past, why should subsequent generations be bound to them? Modern Germans aren't bound by their grandparents' oaths of allegiance to fascism. |
| 18630 | Utilitarianism is no longer a distinctive political position [Kymlicka] |
| Full Idea: Modern utilitarianism, despite its radical heritage, no longer defines a distinctive political position. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 2.6) | |
| A reaction: This is his final sentence on the topic. I suppose utilitarianism exists as a moral theory at too high a level of generality to count as a political theory. |
| 18623 | The quest of the general good is partly undermined by people's past entitlements [Kymlicka] |
| Full Idea: The existence of past entitlements on the part of particular people partially pre-empts, or constrains, the utilitarian quest to maximise the general good. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 2.3.a) | |
| A reaction: In other words, there is never a clean slate in politics (except in some hideously violent revolution). You might be able to justify to someone a withdrawal of their past entitlements. E.g. confiscating a stolen painting that was bought in ignorance. |
| 18628 | We shouldn't endorse preferences which reject equality, and show prejudice and selfishness [Kymlicka] |
| Full Idea: Equality should enter into the very formation of our preferences. ....Prejudiced and selfish preferences should be excluded from the start, for they already reflect a failure to show equal consideration. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 2.5.b) | |
| A reaction: This is meant to block utilitarian summing of preferences like racism, but it feels like a rather desperate attempt to get righteous liberal values in at the beginning, where they can't be questioned. How can you justify equal respect and treatment? |
| 18629 | Using utilitarian principles to make decisions encourages cold detachment from people [Kymlicka] |
| Full Idea: Acting directly on utilitarian grounds is counter-productive, for it encourages a contingent and detached attitude towards what should be whole-hearted personal and political commitments. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 2.7) | |
| A reaction: I've always seen this as an objection to utilitarianism, but I now see that it is only an objection to the decision procedure. We should be warm-hearted and committed, in the knowledge that this will increase benefits to all. Hm. A bit schizoid. |
| 18637 | Utilitarianism is irrational if it tells you to trade in your rights and resources just for benefits [Kymlicka] |
| Full Idea: Utilitarianism is an irrational choice, for it is rational to ensure your basic rights and resources are protected, even if you thereby lessen your chance of receiving benefits above and beyond the basic goods that you seek to protect. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 3.3) | |
| A reaction: [He's discussing Rawls] Utilitarians would obviously respond to this by saying that the rights and resources are needed to protect future benefits, so it would be short-termism to trade them in now. |
| 18663 | Modern liberalism has added personal privacy to our personal social lives [Kymlicka] |
| Full Idea: Modern liberalism is concerned not only to protect the private sphere of social life, but also to carve out a realm within the private sphere where individuals can have privacy. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 7.2.b) | |
| A reaction: Interestingly, he associates this development with the romantic movement, which designated social interaction as public and political, creating a need for true privacy. Privacy is the blessing and blight of the modern world. |
| 18632 | Liberalism tends to give priority to basic liberties [Kymlicka] |
| Full Idea: One way of differentiating liberalism is that it gives priority to the basic liberties. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 3.1.b) | |
| A reaction: [He is citing Rawls for this] This is not the same as extreme libertarianism, which makes liberty the only priority. The issue would be over which liberties count as 'basic'. Taxation would be a good test case. |
| 18656 | Marxists say liberalism is unjust, because it allows exploitation in the sale of labour [Kymlicka] |
| Full Idea: The fundamental flaw of liberal justice, Marxists claim, is that it licences the continuation of the worker by the capitalist, since it licences the buying and selling labour. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 5.2.a) | |
| A reaction: I can't see that all sale of labour is exploitation, if (for example) the wage paid was extremely high (maybe even higher than the employer's wage, which is possible). So exploitation involves something more. |
| 18659 | The 'Kantian' view of the self misses the way it is embedded or situated in society [Kymlicka] |
| Full Idea: Communitarians believe that the 'Kantian' view of the self is false, because it ignores the fact that the self is 'embedded' or 'situated' in existing social practices, so that we cannot always stand back and opt out of them. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 6.3) | |
| A reaction: [Hegel and Charles Taylor 1979 seem to be the sources for this] I have several times been told that I am so typical of the culture I arose in that it is almost comical. This was quite disconcerting, but I got used to it, and now I love it. |
| 18660 | Communitarians say we should pay more attention to our history [Kymlicka] |
| Full Idea: Communitarians like to say that political theory should pay more attention to the history of each culture. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 6.4.c) | |
| A reaction: I like this. Kylicka says communitarians tend not to do this, partly because history might reveal an unpleasant basis for present society (such as English country house life benefiting from slavery). The ignorance of history among politicians appals me. |
| 18657 | Communitarian states only encourage fairly orthodox ideas of the good life [Kymlicka] |
| Full Idea: A communitarian state can and should encourage people to adopt conceptions of the good that conform to the community's way of life, while discouraging conceptions of the good that conflict with it. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 6.2) | |
| A reaction: This is the conservative aspect of communitarianism which many people (notably liberals) find uncongenial. This conservatism is implicit in Aristotle's account of virtue. I have become more conservative to accommodate it. |
| 18649 | If everyone owned himself, that would prevent slavery [Kymlicka] |
| Full Idea: The best way to prevent enslavement of one person to another is to give each person ownership over himself. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 4.2.c) | |
| A reaction: [The idea comes from Nozick, but Kymlicka is assessing how it should be understood] The best way to block any social evil like slavery is to make it unthinkable. Legislation is second best. Presumably I could sell myself into slavery (like Faust)? |
| 18640 | Libertarians like the free market, but they also think that the free market is just [Kymlicka] |
| Full Idea: Not everyone who favours the free market is a libertarian, for they do not all share the libertarian view that the free market is inherently just. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 4.1.a) | |
| A reaction: Illuminating. It would appear that exploitation is possible within a strictly free market, so it seems unlikely that free markets are inherently just (unless you don't acknowledge that 'exploitation' is wrong). |
| 18651 | The most valuable liberties to us need not be the ones with the most freedom [Kymlicka] |
| Full Idea: Different liberties promote different interests for many different reasons, and there is no reason to assume that the liberties which are most valuable to us are the ones with the most freedom. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 2.4.a.iii) | |
| A reaction: As I grow older I come more and more to think that freedom is overvalued. But have you tried the other thing? We complacently take huge freedoms for granted. Be passionate about fundamental freedoms, and relaxed about the rest. |
| 18661 | Ancient freedom was free participation in politics, not private independence of life [Kymlicka] |
| Full Idea: The liberty of the ancients was their active participation in the exercise of political power, not the peaceful enjoyment of personal independence. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 7.2.a) | |
| A reaction: Interesting. It takes a feat of imagination to grasp a world where the desire for freedom to sit at home and compile a database of philosophical ideas never even crossed anyone's mind. |
| 18633 | Equal opportunities seems fair, because your fate is from your choices, not your circumstances [Kymlicka] |
| Full Idea: The ideology of equal opportunity seems fair to many people in our society because it ensures that people's fate is determined by their choices, rather than their circumstances. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 3.2) | |
| A reaction: Is it that we surmise that people have 'free will', and then engineer a situation where it can be exercised? Is it that the rest of us don't want to feel guilty when someone else's life goes awry (because it was 'their fault')? |
| 18634 | Equal opportunity arbitrarily worries about social circumstances, but ignores talents [Kymlicka] |
| Full Idea: The prevailing view [of equal opportunity] only recognises differences in social circumstances, while ignoring differences in natural talents (or treating them as if they were a choice). This is an arbitrary limit on the theory's central intuition. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 3.2) | |
| A reaction: Of course we (society) can do a lot about your social circumstances, but very little about your talents, other than to develop them or thwart them. Talented children need more than mere 'opportunity'. |
| 18654 | Marxists say justice is unneeded in the truly good community [Kymlicka] |
| Full Idea: Marxists believe that justice, far from being the first virtue of social institutions, is something that the truly good community has no need for. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 5.1) | |
| A reaction: This seems to imply that in the truly good community there are nothing but truly good individuals, which is taking social determinism to its limits. Are all the citizens of a bad community inherently bad? |
| 18652 | The Lockean view of freedom depends on whether you had a right to what is restricted [Kymlicka] |
| Full Idea: The Lockean camp defines freedom in terms of the exercise of our rights. Whether or not a restriction decreases our freedom depends on whether or not we had a right to do the restricted thing. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 2.4.a.iii) | |
| A reaction: My first instinct is to be sympathetic to this, since a detached and general notion of 'freedom' strikes me as suspect. He offers the rival 'Spenserian' view of freedom as just having the choice. |
| 18655 | Justice corrects social faults, but also expresses respect to individuals as ends [Kymlicka] |
| Full Idea: Justice is more than a remedial virtue. It does remedy defects in social co-ordination, ...but it also expresses the respect individuals are owed as ends in themselves, not as mean's to someone's good, or even to the common good. | |
| From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 5.1) | |
| A reaction: That is, I take it, that justice operates at two different levels in our theoretical social thinking. |
| 1748 | Archelaus was the first person to say that the universe is boundless [Archelaus, by Diog. Laertius] |
| Full Idea: Archelaus was the first person to say that the universe is boundless. | |
| From: report of Archelaus (fragments/reports [c.450 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.Ar.3 |
| 12681 | There are natural kinds of processes [Ellis] |
| Full Idea: There are natural kinds of processes. | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 3) | |
| A reaction: Interesting. I am tempted by the view that processes are the most basic feature of reality, since I think of the mind as a process, and quantum reality seems more like processes than like objects. |
| 12680 | Natural kind structures go right down to the bottom level [Ellis] |
| Full Idea: Natural kind structures go all the way down to the most basic levels of existence. | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 3) | |
| A reaction: Even the bottom level? Is there anything to explain why the bottom level is a kind, given that all the higher kinds presumably have an explanation? |
| 12675 | Laws of nature are just descriptions of how things are disposed to behave [Ellis] |
| Full Idea: The laws of nature must be supposed to be just descriptions of the ways in which things are intrinsically disposed to behave: of how they would behave if they existed as closed and isolated systems. | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 3) | |
| A reaction: I agree with this, and therefore take 'laws of nature' to be eliminable from any plausible ontology (which just contains the things and their behaviour). Ellis tends to defend laws, when he doesn't need to. |
| 12671 | I deny forces as entities that intervene in causation, but are not themselves causal [Ellis] |
| Full Idea: The classical conception of force is an entity that intervenes between a physical cause and its effect, but is not itself a physical cause. I see no reason to believe in forces of this kind. | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 2) | |
| A reaction: The difference of view between Leibniz and Newton is very illuminating on this one (coming this way soon!). Can you either have forces and drop causation, or have causation and drop forces? |
| 12674 | Energy is the key multi-valued property, vital to scientific realism [Ellis] |
| Full Idea: Perhaps the most important of all multi-valued properties is energy itself. I think a scientific realist must believe that energy exists. | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 2) | |
| A reaction: It's odd that the existence of the most basic thing in physics needs a credo from a certain sort of believer. I have been bothered by notion of 'energy' for fifty years, and am still none the wiser. I'm sure I could be scientific realist without it. |
| 12689 | Simultaneity can be temporal equidistance from the Big Bang [Ellis] |
| Full Idea: Cosmologists have a concept of objective simultaneity, which they take to mean something like 'temporally equidistant from the Big Bang'. | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 6) | |
| A reaction: I find this very appealing, when faced with all the relativity theory that tells me there is no such thing as global simultaneity, a claim which I find deeply counterintuitive, but seems to have the science on its side. Bravo. |
| 12690 | The present is the collapse of the light wavefront from the Big Bang [Ellis] |
| Full Idea: The global wavefront that collapses when a light signal from the Big Bang is observed is what most plausibly defines the frontier between past and future. | |
| From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 6) | |
| A reaction: I'm not sure I understand this, but it is clearly worth passing on. Of all the deep mysteries, the 'present' time may be the deepest. |
| 5989 | Archelaus said life began in a primeval slime [Archelaus, by Schofield] |
| Full Idea: Archelaus wrote that life on Earth began in a primeval slime. | |
| From: report of Archelaus (fragments/reports [c.450 BCE]) by Malcolm Schofield - Archelaus | |
