| 8014 | Resolve a complex into simple elements, then reconstruct the complex by using them [Hobbes, by MacIntyre] |
| Full Idea: Hobbes took his method from Galileo, of resolving any complex situation into its logically primitive, simple elements and then using the simple elements to show how the complex situation could be reconstructed. | |
| From: report of Thomas Hobbes (Leviathan [1651]) by Alasdair MacIntyre - A Short History of Ethics Ch.10 | |
| A reaction: Reverse engineering of reality. This idea, wherever it comes from, strikes me as the key to the advance of human understanding. No one has yet improved on it as a method, in science or philosophy. Reconstruction needs the mechanism. |
| 7559 | Every part of the universe is body, and non-body is not part of it [Hobbes] |
| Full Idea: The world is corporeal, that is to say, body...and every part of the universe is body, and that which is not body is no part of the universe. | |
| From: Thomas Hobbes (Leviathan [1651], IV.46) | |
| A reaction: [Hobbes concedes existence to visible spirits, but not invisible ones]. This is the kind of remark which got Hobbes hated. It is also the sort of thing that makes him the best candidate for the 'first modern man'. |
| 16185 | Causality indicates which properties are real [Cartwright,N] |
| Full Idea: Causality is a clue to what properties are real. | |
| From: Nancy Cartwright (How the Laws of Physics Lie [1983], 9.3) | |
| A reaction: An interesting variant on the Shoemaker proposal that properties actually are causal. I'm not sure that there is anything more to causality that the expression in action of properties, which I take to be powers. Structures are not properties. |
| 14508 | A 'thisness' is a thing's property of being identical with itself (not the possession of self-identity) [Adams,RM] |
| Full Idea: A thisness is the property of being identical with a certain particular individual - not the property that we all share, of being identical with some individual, but my property of being identical with me, your property of being identical with you etc. | |
| From: Robert Merrihew Adams (Primitive Thisness and Primitive Identity [1979], 1) | |
| A reaction: These philosophers tell you that a thisness 'is' so-and-so, and don't admit that he (and Plantinga) are putting forward a new theory about haecceities, and one I find implausible. I just don't believe in the property of 'being-identical-to-me'. |
| 14511 | There are cases where mere qualities would not ensure an intrinsic identity [Adams,RM] |
| Full Idea: I have argued that there are possible cases in which no purely qualitative conditions would be both necessary and sufficient for possessing a given thisness. | |
| From: Robert Merrihew Adams (Primitive Thisness and Primitive Identity [1979], 6) | |
| A reaction: Are we perhaps confusing our epistemology with our ontology here? We can ensure that something has identity, or ensure that its identity is knowable. If it is 'something', then it has identity. Er, that's it? |
| 12031 | Essences are taken to be qualitative properties [Adams,RM] |
| Full Idea: Essences have normally been understood to be constituted by qualitative properties. | |
| From: Robert Merrihew Adams (Primitive Thisness and Primitive Identity [1979], 1) | |
| A reaction: I add this simple point, because it might be challenged by the view that an essence is a substance, rather than the properties of anything. I prefer that, and would add that substances are individuated by distinctive causal powers. |
| 12034 | If the universe was cyclical, totally indiscernible events might occur from time to time [Adams,RM] |
| Full Idea: There is a temporal argument for the possibility of non-identical indiscernibles, if there could be a cyclical universe, in which each event was preceded and followed by infinitely many other events qualitatively indiscernible from itself. | |
| From: Robert Merrihew Adams (Primitive Thisness and Primitive Identity [1979], 3) | |
| A reaction: The argument is a parallel to Max Black's indiscernible spheres in space. Adams offers the reply that time might be tightly 'curved', so that the repetition was indeed the same event again. |
| 14510 | Two events might be indiscernible yet distinct, if there was a universe cyclical in time [Adams,RM] |
| Full Idea: Similar to the argument from spatial dispersal, we can argue against the Identity of Indiscernibles from temporal dispersal. It seems there could be a cyclic universe, ..and thus there could be distinct but indiscernible events, separated temporally. | |
| From: Robert Merrihew Adams (Primitive Thisness and Primitive Identity [1979], 3) | |
| A reaction: See Idea 14509 for spatial dispersal. If cosmologists decided that a cyclical universe was incoherent, would that ruin the argument? Presumably there might even be indistinguishable events in the one universe (in principle!). |
| 16455 | Black's two globes might be one globe in highly curved space [Adams,RM] |
| Full Idea: If God creates a globe reached by travelling two diameters in a straight line from another globe, this can be described as two globes in Euclidean space, or a single globe in a tightly curved non-Euclidean space. | |
| From: Robert Merrihew Adams (Primitive Thisness and Primitive Identity [1979], 3) | |
| A reaction: [my compression of Adams's version of Hacking's response to Black, as spotted by Stalnaker] Hence we save the identity of indiscernibles, by saying we can't be sure that two indiscernibles are not one thing, unusually described. |
| 14507 | Are possible worlds just qualities, or do they include primitive identities as well? [Adams,RM] |
| Full Idea: Is the world - and are all possible worlds - constituted by purely qualitative facts, or does thisness hold a place beside suchness as a fundamental feature of reality? | |
| From: Robert Merrihew Adams (Primitive Thisness and Primitive Identity [1979], Intro) | |
| A reaction: 'Thisness' and 'suchness' aim to capture Aristotelian notions of the entity and its attributes. Aristotle talks of 'a this'. Adams is after adding 'haecceities' to the world. My intuitive answer is no, there are no 'pure' identities. We add those. |
| 11964 | Possible worlds are world-stories, maximal descriptions of whole non-existent worlds [Adams,RM, by Molnar] |
| Full Idea: According to a theory proposed by Adams, possible worlds are world-stories, that is maximally complete consistent sets of propositions which between them describe non-existent whole worlds. | |
| From: report of Robert Merrihew Adams (Primitive Thisness and Primitive Identity [1979]) by George Molnar - Powers 12.2.2 | |
| A reaction: Presumably this places an additional constraint on the view that a world is just a maximal set of propositions. It seems to require coherence as well as consistency. Suppose an object destroys all others objects. Is that a world? |
| 16451 | Adams says anti-haecceitism reduces all thisness to suchness [Adams,RM, by Stalnaker] |
| Full Idea: The anti-haecceitist thesis (according to Adams's version) is that all thisnesses are reducible to, or supervenient upon, suchnesses. | |
| From: report of Robert Merrihew Adams (Primitive Thisness and Primitive Identity [1979]) by Robert C. Stalnaker - Mere Possibilities 3.5 |
| 11901 | Haecceitism may or may not involve some logical connection to essence [Adams,RM, by Mackie,P] |
| Full Idea: Moderate Haecceitism says that thisnesses and transworld identities are primitive, but logically connected with suchnesses. ..Extreme Haecceitism involves the rejection of all logical connections between suchness and thisness, for persons. | |
| From: report of Robert Merrihew Adams (Primitive Thisness and Primitive Identity [1979]) by Penelope Mackie - How Things Might Have Been | |
| A reaction: I am coming to the conclusion that they are not linked. That thisness is a feature of our conceptual thinking, and is utterly atomistic and content-free, while suchness is rich and a feature of reality. |
| 14512 | Moderate Haecceitism says transworld identities are primitive, but connected to qualities [Adams,RM] |
| Full Idea: My position, according to which thisnesses and transworld identities are primitive but logically connected to suchnesses, we may call 'Moderate Haecceitism'. | |
| From: Robert Merrihew Adams (Primitive Thisness and Primitive Identity [1979], 6) | |
| A reaction: The rather tentative connection to qualities is to block the possibility of Aristotle being a poached egg, which he (quite reasonably!) holds to be counterintuitive. It all feels like a mess to me. |
| 2356 | Appearance and reality can be separated by mirrors and echoes [Hobbes] |
| Full Idea: If colours or sounds were in the bodies or objects that cause them, they could not be severed from them, as by glasses, and in echoes by reflection, we see they are; where we know the thing we see is in one place, the appearance in another. | |
| From: Thomas Hobbes (Leviathan [1651], 1.01) |
| 2357 | Dreams must be false because they seem absurd, but dreams don't see waking as absurd [Hobbes] |
| Full Idea: Because waking I often observe the absurdity of dreams, but never dream of the absurdity of my waking thoughts, I am well satisfied that, being awake, I know I dream not, though when I dream I think myself awake. | |
| From: Thomas Hobbes (Leviathan [1651], 1.02) |
| 16182 | Two main types of explanation are by causes, or by citing a theoretical framework [Cartwright,N] |
| Full Idea: In explaining a phenomenon one can cite the causes of that phenomenon; or one can set the phenomenon in a general theoretical framework. | |
| From: Nancy Cartwright (How the Laws of Physics Lie [1983], 4.1) | |
| A reaction: The thing is, you need to root an explanation in something taken as basic, and theoretical frameworks need further explanation, whereas causes seem to be basic. |
| 16184 | An explanation is a model that fits a theory and predicts the phenomenological laws [Cartwright,N] |
| Full Idea: To explain a phenomenon is to find a model that fits it into the basic framework of the theory and that thus allows us to derive analogues for the messy and complicated phenomenological laws that are true of it. | |
| From: Nancy Cartwright (How the Laws of Physics Lie [1983], 8.3) | |
| A reaction: This summarises the core of her view in this book. She is after models rather than laws, and the models are based on causes. |
| 16167 | Laws get the facts wrong, and explanation rests on improvements and qualifications of laws [Cartwright,N] |
| Full Idea: We explain by ceteris paribus laws, by composition of causes, and by approximations that improve on what the fundamental laws dictate. In all of these cases the fundamental laws patently do not get the facts right. | |
| From: Nancy Cartwright (How the Laws of Physics Lie [1983], Intro) | |
| A reaction: It is rather headline-grabbing to say in this case that laws do not get the facts right. If they were actually 'wrong' and 'lied', there wouldn't be much point in building explanations on them. |
| 16169 | Laws apply to separate domains, but real explanations apply to intersecting domains [Cartwright,N] |
| Full Idea: When different kinds of causes compose, we want to explain what happens in the intersection of different domains. But the laws we use are designed only to tell truly what happens in each domain separately. | |
| From: Nancy Cartwright (How the Laws of Physics Lie [1983], Intro) | |
| A reaction: Since presumably the laws are discovered through experiments which try to separate out a single domain, in those circumstances they actually are true, so they don't 'lie'. |
| 16176 | Covering-law explanation lets us explain storms by falling barometers [Cartwright,N] |
| Full Idea: Much criticism of the original covering-law model objects that it lets in too much. It seems we can explain Henry's failure to get pregnant by his taking birth control pills, and we can explain the storm by the falling barometer. | |
| From: Nancy Cartwright (How the Laws of Physics Lie [1983], 2.0) | |
| A reaction: I take these examples to show that true explanations must be largely causal in character. The physicality of causation is what matters, not 'laws'. I'd say the same of attempts to account for causation through counterfactuals. |
| 16177 | I disagree with the covering-law view that there is a law to cover every single case [Cartwright,N] |
| Full Idea: Covering-law theorists tend to think that nature is well-regulated; in the extreme, that there is a law to cover every case. I do not. | |
| From: Nancy Cartwright (How the Laws of Physics Lie [1983], 2.2) | |
| A reaction: The problem of coincidence is somewhere at the back of this thought. Innumerable events have their own explanations, but it is hard to explain their coincidence (see Aristotle's case of bumping into a friend in the market). |
| 16180 | You can't explain one quail's behaviour by just saying that all quails do it [Cartwright,N] |
| Full Idea: 'Why does that quail in the garden bob its head up and down in that funny way whenever it walks?' …'Because they all do'. | |
| From: Nancy Cartwright (How the Laws of Physics Lie [1983], 3.5) | |
| A reaction: She cites this as an old complaint against the covering-law model of explanation. It captures beautifully the basic error of the approach. We want to know 'why', rather than just have a description of the pattern. 'They all do' is useful information. |
| 16171 | The covering law view assumes that each phenomenon has a 'right' explanation [Cartwright,N] |
| Full Idea: The covering-law account supposes that there is, in principle, one 'right' explanation for each phenomenon. | |
| From: Nancy Cartwright (How the Laws of Physics Lie [1983], Intro) | |
| A reaction: Presumably the law is held to be 'right', but there must be a bit of flexibility in describing the initial conditions, and the explanandum itself. |
| 16183 | In science, best explanations have regularly turned out to be false [Cartwright,N] |
| Full Idea: There are a huge number of cases in the history of science where we now know our best explanations were false. | |
| From: Nancy Cartwright (How the Laws of Physics Lie [1983], 5.3) | |
| A reaction: [She cites Laudan 1981 for this] The Ptolemaic system and aether are the standard example cited for this. I believe strongly in the importance of best explanation. Only a fool would just accept the best explanation available. Coherence is needed. |
| 2358 | Freedom is absence of opposition to action; the idea of 'free will' is absurd [Hobbes] |
| Full Idea: If a man should talk to me of a 'free-will', or any 'free' but free from being hindered by opposition, I should not say that he were in an error, but that his words were without a meaning, that is to say, absurd. | |
| From: Thomas Hobbes (Leviathan [1651], 1.05) |
| 6214 | Liberty and necessity are consistent, as when water freely flows, by necessity [Hobbes] |
| Full Idea: Liberty and necessity are consistent: as in the water, that hath not only liberty, but a necessity of descending by the channel. | |
| From: Thomas Hobbes (Leviathan [1651], II.Ch.XI) | |
| A reaction: Hume asserts something similar (Idea 2223), but they both miss the point, which is that libertarians about water would have to believe it didn't need to follow gravity, but could refuse to flow. Freedom of will and freedom of action are quite different. |
| 23987 | The 'simple passions' are appetite, desire, love, aversion, hate, joy, and grief [Hobbes, by Goldie] |
| Full Idea: For Hobbes the 'simple passions' were appetite, desire, love, aversion, hate, joy, and grief. | |
| From: report of Thomas Hobbes (Leviathan [1651], I.6) by Peter Goldie - The Emotions 4 'Evidence' | |
| A reaction: This is the standard approach to emotions of Hobbes's time. Modern thinkers probably reject the idea that passions can be simple or basic. Rightly, I think. |
| 12032 | Direct reference is by proper names, or indexicals, or referential uses of descriptions [Adams,RM] |
| Full Idea: Direct reference is commonly effected by the use of proper names and indexical expressions, and sometimes by what has been called (by Donnellan) the 'referential' use of descriptions. | |
| From: Robert Merrihew Adams (Primitive Thisness and Primitive Identity [1979], 2) | |
| A reaction: One might enquire whether the third usage should be described as 'direct', but then I am not sure that there is much of a distinction between references which are or are not 'direct'. Either you (or a sentence) refer or you (or it) don't. |
| 2362 | The will is just the last appetite before action [Hobbes] |
| Full Idea: In deliberation, the last appetite or aversion immediately adhering to the action, or to the omission thereof, is that we call the Will. | |
| From: Thomas Hobbes (Leviathan [1651], 1.06) | |
| A reaction: I share his caution about 'the will', but his observation strikes me as inaccurate. When I drink, my 'will' is not my thirst. I take the will to be a feature of my reason. I gave my thirst permission to indulge itself. The will is practical reason? |
| 2363 | Reason is usually general, but deliberation is of particulars [Hobbes] |
| Full Idea: Reasoning is in general words, but deliberation for the most part is of particulars. | |
| From: Thomas Hobbes (Leviathan [1651], 1.06) |
| 2360 | 'Good' is just what we desire, and 'Evil' what we hate [Hobbes] |
| Full Idea: Whatsoever is the object of any man's appetite or desire, that is it which he for his part calleth 'Good'; and the object of his hate or aversion 'Evil'. | |
| From: Thomas Hobbes (Leviathan [1651], 1.06) | |
| A reaction: This meets the Frege-Geach Problem - that we can have these feelings while reading ancient history, but we can't possibly 'desire' any of that. This is better on evil than on good. |
| 2368 | Men's natural desires are no sin, and neither are their actions, until law makes it so [Hobbes] |
| Full Idea: The desires and other passions of man are in themselves no sin. No more are the actions that proceed from those passions, till they know a law that forbids them. | |
| From: Thomas Hobbes (Leviathan [1651], 1.13) | |
| A reaction: That is a pretty flat rejection of natural law, as you might expect from an empiricist. So prior to the first law-making, no one ever did anything wrong? Hm. |
| 2359 | Desire and love are the same, but in the desire the object is absent, and in love it is present [Hobbes] |
| Full Idea: Desire and love are the same thing, save that by desire we always signify the absence of the object, by love most commonly the presence of the same. | |
| From: Thomas Hobbes (Leviathan [1651], 1.06) | |
| A reaction: Implausible reductivism from Hobbes. Plenty of counterexamples to this. You work it out! |
| 2370 | All voluntary acts aim at some good for the doer [Hobbes] |
| Full Idea: Of the voluntary acts of every man, the object is some good to himself. | |
| From: Thomas Hobbes (Leviathan [1651], 1.14) | |
| A reaction: Nonsense. You can only describe sacrificial acts for loved ones, such as children, in this way if this proposal is a tautology. Hobbes cannot know the truth of this claim. |
| 8015 | Hobbes wants a contract to found morality, but shared values are needed to make a contract [MacIntyre on Hobbes] |
| Full Idea: Hobbes makes two incompatible demands of the original contract: he wishes it to be the foundation of all shared and common standards and rules; but he also wishes it to be a contract, which needs prior shared and common standards. | |
| From: comment on Thomas Hobbes (Leviathan [1651], Pt 1) by Alasdair MacIntyre - A Short History of Ethics Ch.10 | |
| A reaction: At the very least, the participants in a contract must be committed to keeping it even when it is not convenient. But a common purpose seems to be needed too, which makes the contract itself intrinsically valuable. Similar objections to Kant. |
| 2371 | A contract is a mutual transfer of rights [Hobbes] |
| Full Idea: The mutual transferring of right is that which men call 'contract'. | |
| From: Thomas Hobbes (Leviathan [1651], 1.14) |
| 2372 | The person who performs first in a contract is said to 'merit' the return, and is owed it [Hobbes] |
| Full Idea: He that performeth first in the case of a contract, is said to 'merit' that which he is to receive by the performance of the other, and he hath it as due. | |
| From: Thomas Hobbes (Leviathan [1651], 1.14) |
| 5337 | For Hobbes the Golden Rule concerns not doing things, whereas Jesus encourages active love [Hobbes, by Flanagan] |
| Full Idea: Hobbes put the Golden Rule as 'do NOT do to others what you would NOT want done to yourself'. Jesus's formulation encouraged active love. Most Westerners conceive their moral duty as not to do harm, rather than actively doing good. | |
| From: report of Thomas Hobbes (Leviathan [1651]) by Owen Flanagan - The Problem of the Soul p.20n | |
| A reaction: This idea probably runs very deep into western culture, where most people feel that they are being very morally good when they are sitting at home and not actually annoying anyone. Utilitarianism also offers a challenge to such complacency. |
| 2374 | In the violent state of nature, the merest suspicion is enough to justify breaking a contract [Hobbes] |
| Full Idea: If a covenant is made with neither party performing presently, but trust one another, in the condition of mere nature (which is war between men) upon reasonable suspicion, it is void. | |
| From: Thomas Hobbes (Leviathan [1651], 1.14) |
| 2375 | Suspicion will not destroy a contract, if there is a common power to enforce it [Hobbes] |
| Full Idea: If there be a common power set over both parties in a contract, with right and force sufficient to compel performance, a contract does not become void as soon as the parties are suspicious. | |
| From: Thomas Hobbes (Leviathan [1651], 1.14) |
| 8016 | Fear of sanctions is the only motive for acceptance of authority that Hobbes can think of [MacIntyre on Hobbes] |
| Full Idea: Hobbes has such a limited view of human motives that he cannot provide any other explanation for the acceptance of authority than the fear of sanctions.. | |
| From: comment on Thomas Hobbes (Leviathan [1651], Pt 1) by Alasdair MacIntyre - A Short History of Ethics Ch.10 | |
| A reaction: There are two alternative views - the conservative view that people naturally welcome and even need authority, because they need to be led; or the Aristotelian view that people are naturally communal, and authority is part of community life. |
| 2377 | No one who admitted to not keeping contracts could ever be accepted as a citizen [Hobbes] |
| Full Idea: He therefore that breaketh his covenant, and consequently declareth that he thinks he may with reason do so, cannot be received into any society. | |
| From: Thomas Hobbes (Leviathan [1651], 1.15) |
| 2379 | If there is a good reason for breaking a contract, the same reason should have stopped the making of it [Hobbes] |
| Full Idea: If any fault of man be sufficient to discharge our covenant made, the same ought in reason to have been sufficient to have hindered the making of it. | |
| From: Thomas Hobbes (Leviathan [1651], 1.15) |
| 2373 | The first performer in a contract is handing himself over to an enemy [Hobbes] |
| Full Idea: He which performeth first in a contract, does but betray himself to his enemy. | |
| From: Thomas Hobbes (Leviathan [1651], 1.14) |
| 2382 | Someone who keeps all his contracts when others are breaking them is making himself a prey to others [Hobbes] |
| Full Idea: He that should be modest and tractable, and perform all the promises, in such time and place where no man else should do so, should but make himself a prey to others. | |
| From: Thomas Hobbes (Leviathan [1651], 1.15) |
| 2383 | Virtues are a means to peaceful, sociable and comfortable living [Hobbes] |
| Full Idea: The writers of moral philosophy, though they acknowledge the same virtues and vices, yet not seeing wherein consisted their goodness, nor that they come to be praised as the means of peaceable, sociable and comfortable living. | |
| From: Thomas Hobbes (Leviathan [1651], 1.15) |
| 2376 | Injustice is the failure to keep a contract, and justice is the constant will to give what is owed [Hobbes] |
| Full Idea: The definition of 'injustice' is no other than the not performance of covenant….. and 'justice' is the constant will of giving to every man his own. | |
| From: Thomas Hobbes (Leviathan [1651], 1.15) |
| 2367 | In time of war the life of man is solitary, poor, nasty, brutish and short [Hobbes] |
| Full Idea: In a time of war…. there is continual fear, and danger of violent death, and the life of man is solitary, poor, nasty, brutish and short. | |
| From: Thomas Hobbes (Leviathan [1651], 1.13) |
| 19764 | Hobbes attributed to savages the passions which arise in a law-bound society [Hobbes, by Rousseau] |
| Full Idea: Hobbes had wrongly injected into the savage man's concern for self-preservation the need to satisfy a multitude of passions which are the product of society and which have made laws necessary. | |
| From: report of Thomas Hobbes (Leviathan [1651]) by Jean-Jacques Rousseau - Discourse on the Origin of Inequality Part I | |
| A reaction: Hobbes's famous remark concerns a state of war, which is quite a sophisticated state of conflict between well formed social groups. Rousseau's savage is fairly solitary, so won't be involved in war. |
| 20566 | Hobbes says the people voluntarily give up their sovereignty, in a contract with a ruler [Hobbes, by Oksala] |
| Full Idea: While Hobbes had held that the people were the final source of political authority, he had argued that in entering the social contract they gave up their sovereignty by transferring all power to an absolute ruler. | |
| From: report of Thomas Hobbes (Leviathan [1651]) by Johanna Oksala - Political Philosophy: all that matters Ch.5 | |
| A reaction: Later the idea of 'inalienable' rights crept in. If you volunteer for exploitation or slavery, that still doesn't justify them. Sadism is presumably not justified by masochism. |
| 2366 | There is not enough difference between people for one to claim more benefit than another [Hobbes] |
| Full Idea: The difference between man and man is not so considerable as that one man can thereupon claim to himself any benefit to which another may not pretend as well as he. | |
| From: Thomas Hobbes (Leviathan [1651], 1.13) |
| 20485 | Hobbes says people are roughly equal; Locke says there is no right to impose inequality [Hobbes, by Wolff,J] |
| Full Idea: Hobbes's principle of equality was a claim about the mental and physical capabilities of all people. For Locke it is a moral claim about rights: no person has a natural right to subordinate any other. | |
| From: report of Thomas Hobbes (Leviathan [1651]) by Jonathan Wolff - An Introduction to Political Philosophy (Rev) 1 'Locke' | |
| A reaction: There are obvious questions to ask about the claim that people are naturally equal. For the second one, does the lion have a natural right to subordinate the gazelle? Who cares! I'm inclined to be consequentialist about equality. |
| 2369 | If we seek peace and defend ourselves, we must compromise on our rights [Hobbes] |
| Full Idea: From the first law of nature (that we seek peace, but also defend ourselves) comes the second: that a man be willing to lay down his rights to all things, and be contented with so much liberty against other men as he would allow other men against himself. | |
| From: Thomas Hobbes (Leviathan [1651], 1.14) |
| 20484 | We should obey the laws of nature, provided other people are also obeying them [Hobbes, by Wolff,J] |
| Full Idea: Hobbes's position is that we have a duty to obey the Laws of Nature when others around us are known (or can reasonably be expected) to be obeying them too, and so our compliance will not be exploited. | |
| From: report of Thomas Hobbes (Leviathan [1651]) by Jonathan Wolff - An Introduction to Political Philosophy (Rev) 1 'Hobbes' | |
| A reaction: In particular, we should keep contracts. Hobbes doesn't seem fully committed to keeping facts and values separate. |
| 7573 | The legal positivism of Hobbes said law is just formal or procedural [Hobbes, by Jolley] |
| Full Idea: Hobbes was one of the first to propose the view known as 'legal positivism' - that the criterion for deciding whether a rule is a genuine law is entirely formal or procedural | |
| From: report of Thomas Hobbes (Leviathan [1651]) by Nicholas Jolley - Leibniz Ch.7 | |
| A reaction: This was opposed to the tradition of natural law, deriving from Aquinas. It is part of a picture of values draining out of the world as science comes to dominate. The is/ought distinction is its culmination. Power replaces virtue, and Thrasymachus wins. |
| 2380 | Punishment should only be for reform or deterrence [Hobbes] |
| Full Idea: We are forbidden to inflict punishment with any other design than for correction of the offender, or direction of others. | |
| From: Thomas Hobbes (Leviathan [1651], 1.15) |
| 2361 | If fear of unknown powers is legal it is religion, if it is illegal it is superstition [Hobbes] |
| Full Idea: Fear of power invisible, feigned by the mind or imagined from tales publicly allowed, is religion; not allowed, is superstition. | |
| From: Thomas Hobbes (Leviathan [1651], 1.06) |
| 16175 | A cause won't increase the effect frequency if other causes keep interfering [Cartwright,N] |
| Full Idea: A cause ought to increase the frequency of the effect, but this fact may not show up in the probabilities if other causes are at work. | |
| From: Nancy Cartwright (How the Laws of Physics Lie [1983], 1.1) | |
| A reaction: [She cites Patrick Suppes for this one] Presumably in experimental situations you can weed out the interference, but that threatens to eliminate mere 'probability' entirely. |
| 2364 | Causation is only observation of similar events following each other, with nothing visible in between [Hobbes] |
| Full Idea: In knowing the meaning of 'causing', men can only observe and remember what they have seen to precede the like effect at some other time, without seeing between the antecedent and subsequent event any dependence or connexion at all. | |
| From: Thomas Hobbes (Leviathan [1651], 1.12) |
| 6781 | There are fundamental explanatory laws (false!), and phenomenological laws (regularities) [Cartwright,N, by Bird] |
| Full Idea: Nancy Cartwright distinguishes between 'fundamental explanatory laws', which we should not believe, and 'phenomenological laws', which are regularities established on the basis of observation. | |
| From: report of Nancy Cartwright (How the Laws of Physics Lie [1983]) by Alexander Bird - Philosophy of Science Ch.4 | |
| A reaction: The distinction is helpful, so that we can be clearer about what everyone is claiming. We can probably all agree on the phenomenological laws, which are epistemological. Personally I claim truth for the best fundamental explanatory laws. |
| 16166 | Laws of appearances are 'phenomenological'; laws of reality are 'theoretical' [Cartwright,N] |
| Full Idea: Philosophers distinguish phenomenological from theoretical laws. Phenomenological laws are about appearances; theoretical ones are about the reality behind the appearances. | |
| From: Nancy Cartwright (How the Laws of Physics Lie [1983], Intro) | |
| A reaction: I'm suspecting that Humeans only really believe in the phenomenological kind. I'm only interested in the theoretical kind, and I take inference to the best explanation to be the bridge between the two. Cartwright rejects the theoretical laws. |
| 16179 | Good organisation may not be true, and the truth may not organise very much [Cartwright,N] |
| Full Idea: There is no reason to think that the principles that best organise will be true, nor that the principles that are true will organise much. | |
| From: Nancy Cartwright (How the Laws of Physics Lie [1983], 2.5) | |
| A reaction: This is aimed at the Mill-Ramsey-Lewis account of laws, as axiomatisations of the observed patterns in nature. |
| 16170 | To get from facts to equations, we need a prepared descriptions suited to mathematics [Cartwright,N] |
| Full Idea: To get from a detailed factual knowledge of a situation to an equation, we must prepare the description of the situation to meet the mathematical needs of the theory. | |
| From: Nancy Cartwright (How the Laws of Physics Lie [1983], Intro) | |
| A reaction: She is clearly on to something here, as Galileo is blatantly wrong in his claim that the book of nature is written in mathematics. Mathematics is the best we can manage in getting a grip on the chaos. |
| 16181 | Simple laws have quite different outcomes when they act in combinations [Cartwright,N] |
| Full Idea: For explanation simple laws must have the same form when they act together as when they act singly. ..But then what the law states cannot literally be true, for the consequences that occur if it acts alone are not what occurs when they act in combination. | |
| From: Nancy Cartwright (How the Laws of Physics Lie [1983], 3.6) | |
| A reaction: This is Cartwright's basic thesis. Her point is that the laws 'lie', because they claim to predict a particular outcome which never ever actually occurs. She says we could know all the laws, and still not be able to explain anything. |
| 16178 | There are few laws for when one theory meets another [Cartwright,N] |
| Full Idea: Where theories intersect, laws are usually hard to come by. | |
| From: Nancy Cartwright (How the Laws of Physics Lie [1983], 2.3) | |
| A reaction: There are attempts at so-called 'bridge laws', to get from complex theories to simple ones, but her point is well made about theories on the same 'level'. |
| 2365 | Religion is built on ignorance and misinterpretation of what is unknown or frightening [Hobbes] |
| Full Idea: In these four things - opinion of ghosts, ignorance of second causes, devotion towards what men fear, and taking of things casual for prognostics, consisteth the natural seed of religion. | |
| From: Thomas Hobbes (Leviathan [1651], 1.12) |
| 2378 | Belief in an afterlife is based on poorly founded gossip [Hobbes] |
| Full Idea: Knowledge of man's estate after death, and its rewards, is a belief grounded upon other men's sayings that they knew it supernaturally, or they knew those, that knew those, that knew others, that knew it supernaturally. | |
| From: Thomas Hobbes (Leviathan [1651], 1.15) |
