23350 | A wise philosophers uses reason to cautiously judge each aspect of living [Epictetus] |
Full Idea: The sinews of a philosopher are desire that never fails in its achievement; aversion that never meets with what it would avoid; appropriate impulse; carefully considered purpose; and assent that is never precipitate. | |
From: Epictetus (The Discourses [c.56], 2.08.29) | |
A reaction: This is a very individual view of wisdom and the philosopher, whereas wisdom is often thought to have a social role. Is it not important for a philosopher to at least offer advice? |
23355 | The task of philosophy is to establish standards, as occurs with weights and measures [Epictetus] |
Full Idea: Things are judged and weighed, when we have the standards ready. This is the task of philosophy: to examine and establish the standards. | |
From: Epictetus (The Discourses [c.56], 2.11.24) | |
A reaction: It is interesting that this gives philosophers a very specific social role, and also that it seems to identify epistemology as First Philosophy. Other disciplines, of course, establish their own standards without reference to philosophy. |
21394 | Philosophy is knowing each logos, how they fit together, and what follows from them [Epictetus] |
Full Idea: [Philosophical speculation] consists in knowing the elements of 'logos', what each of them is like, how they fit together, and what follows from them. | |
From: Epictetus (The Discourses [c.56], 4.08.14), quoted by A.A. Long - Hellenistic Philosophy 4.1 | |
A reaction: [Said to echo Zeno] If you substitute understanding for 'logos' (plausibly), I think this is exactly the view of philosophy I would subscribe to. We want to understand each aspect of life, and we want those understandings to cohere with one another. |
20876 | Philosophy investigates the causes of disagreements, and seeks a standard for settling them [Epictetus] |
Full Idea: The start of philosophy is perception of the mutual conflict among people, and a search for its cause, plus the rejection and distrust of mere opinion, an investigation to see if opinion is right, and the discovery of some canon, like scales for weighing. | |
From: Epictetus (The Discourses [c.56], 2.11.13) | |
A reaction: So the number one aim of philosophy is epistemological, to find the criterion for true opinion. But it starts in real life, and would cease to trade if people would just agree. I think we should set the bar higher than that. |
23344 | Reason itself must be compounded from some of our impressions [Epictetus] |
Full Idea: What is reason itself? Something compounded from impressions of a certain kind. | |
From: Epictetus (The Discourses [c.56], 1.20.05) | |
A reaction: This seems to be the only escape from the dead end attempts to rationally justify reason. Making reason a primitive absolute is crazy metaphysics. |
23343 | Because reason performs all analysis, we should analyse reason - but how? [Epictetus] |
Full Idea: Since it is reason that analyses and completes all other things, reason itself should not be left unanalysed. But by what shall it be analysed? ..That is why philosophers put logic first, just as when measuring grain we first examine the measure. | |
From: Epictetus (The Discourses [c.56], 1.17.01) | |
A reaction: The problem of the definitive metre rule in Paris. I say we have to test reason against the physical world, and the measure of reason is truth. Something has to be primitive, but reason is too vague for that role. Idea 23344 agrees with me! |
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. |
23359 | We can't believe apparent falsehoods, or deny apparent truths [Epictetus] |
Full Idea: It is impossible to assent to an apparent falsehood, or to deny an apparent truth. | |
From: Epictetus (The Discourses [c.56], 3.07.15) | |
A reaction: The way some philosophers write you would think that most beliefs just result from private whims or social fashion. That happens, of course, but most beliefs result from direct contact with reality. |
18969 | How do you distinguish three beliefs from four beliefs or two beliefs? [Quine] |
Full Idea: Suppose I say that I have given up precisely three beliefs since lunch. An over-coarse individuation could reduce the number to two, and an over-fine one could raise it to four. | |
From: Willard Quine (Propositional Objects [1965], p.144) | |
A reaction: Obviously if you ask how many beliefs I hold, it would be crazy to give a precise answer. But if I search for my cat, I give up my belief that it is in the kitchen, in the lounge and in the bathroom. That's precise enough to be three beliefs, I think. |
23356 | Self-evidence is most obvious when people who deny a proposition still have to use it [Epictetus] |
Full Idea: It is about the strongest proof one could offer of a proposition being evident, that even he who contradicts it finds himself having to make use of it. | |
From: Epictetus (The Discourses [c.56], 2.20.01) | |
A reaction: Philosophers sometimes make fools of themselves by trying, by the use of elaborate sophistry, to demolish propositions which are self-evidently true. Don't be one of these philosophers! |
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. |
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. |
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. |
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. |
23329 | We make progress when we improve and naturalise our choices, asserting their freedom [Epictetus] |
Full Idea: Progress is when any of you turns to his own faculty of choice, working at it and perfecting it, so as to bring it fully into harmony with nature; elevated, free, unrestrained, unhindered, faithful, self-respecting. | |
From: Epictetus (The Discourses [c.56], 1.04.18) | |
A reaction: [See also Disc.3.5.7] Rationality is the stoic concept of being in 'harmony with nature'. It appears (from reading Frede) that this may be the FIRST EVER reference to free will. Note the very rhetorical way in which it is presented. |
23330 | Freedom is making all things happen by choice, without constraint [Epictetus] |
Full Idea: He is free for whom all things happen in accordance with his choice, and whom no one can constrain. | |
From: Epictetus (The Discourses [c.56], 1.12.09) | |
A reaction: The idea of 'free' will seems to have resulted from a wide extension of the idea of constraint, with global determinism lurking in the background. |
23342 | Freedom is acting by choice, with no constraint possible [Epictetus] |
Full Idea: He is free for whom all things happen in accordance with his choice, and whom no one can constrain. | |
From: Epictetus (The Discourses [c.56], 1.12.09) | |
A reaction: Presumable this means that constraint is absolutely impossible, even by Zeus, and not just contingent possibility, when no one sees me raid the fridge. |
23332 | Zeus gave me a nature which is free (like himself) from all compulsion [Epictetus] |
Full Idea: Zeus placed my good nature in my own power, and gave it to me as he has it himself, free from all hindrance, compulsion and restraint. | |
From: Epictetus (The Discourses [c.56], 3.03.10) | |
A reaction: Although Frede traces the origin of free will to the centrality of choice in moral life (and hence to the elevation of its importance), this remark shows that there is a religious aspect to it. Zeus is supreme, and obviously has free will. |
23331 | Not even Zeus can control what I choose [Epictetus] |
Full Idea: You can fetter my leg, but not even Zeus himself can get the better of my choice. | |
From: Epictetus (The Discourses [c.56], 1.01.23) | |
A reaction: This is the beginnings of the idea of free will. It is based on the accurate observation that the intrinsic privacy of a mind means that no external force can be assured of controlling its actions. Epictetus failed to think of internal forces. |
23338 | You can fetter my leg, but not even Zeus can control my power of choice [Epictetus] |
Full Idea: What are you saying, man? Fetter me? You will fetter my leg; but not even Zeus himself can get the better of my choice. | |
From: Epictetus (The Discourses [c.56], 1.01.23) | |
A reaction: This seems to be the beginning of the idea of 'absolute' freedom, which is conjured up to preserve perfect inegrity and complete responsibility. Obviously you can be prevented from doing what you choose, so this is not compatibilism. |
20875 | If we could foresee the future, we should collaborate with disease and death [Epictetus] |
Full Idea: The philosophers are right to say that if the honorable and good person knew what was going to happen, he would even collaborate with disease, death and lameness. | |
From: Epictetus (The Discourses [c.56], 2.10.05) | |
A reaction: The 'philosophers' must be the earlier stoics, founders of his school. |
23347 | If I know I am fated to be ill, I should want to be ill [Epictetus] |
Full Idea: If I really knew that it was ordained for me to be ill at this moment, I would aspire to be so. | |
From: Epictetus (The Discourses [c.56], 2.06.10) | |
A reaction: The rub, of course, is that it is presumably impossible to know what is fated. Book 2.7 is on divination. I don't see any good in a mortally ill person desiring, for that reason alone, to die. Rage against the dying of the light, I say. |
18967 | A 'proposition' is said to be the timeless cognitive part of the meaning of a sentence [Quine] |
Full Idea: A 'proposition' is the meaning of a sentence. More precisely, since propositions are supposed to be true or false once and for all, it is the meaning of an eternal sentence. More precisely still, it is the 'cognitive' meaning, involving truth, not poetry. | |
From: Willard Quine (Propositional Objects [1965], p.139) | |
A reaction: Quine defines this in order to attack it. I equate a proposition with a thought, and take a sentence to be an attempt to express a proposition. I have no idea why they are supposed to be 'timeless'. Philosophers have some very odd ideas. |
18968 | The problem with propositions is their individuation. When do two sentences express one proposition? [Quine] |
Full Idea: The trouble with propositions, as cognitive meanings of eternal sentences, is individuation. Given two eternal sentences, themselves visibly different linguistically, it is not sufficiently clear under when to say that they mean the same proposition. | |
From: Willard Quine (Propositional Objects [1965], p.140) | |
A reaction: If a group of people agree that two sentences mean the same thing, which happens all the time, I don't see what gives Quine the right to have a philosophical moan about some dubious activity called 'individuation'. |
23325 | Epictetus developed a notion of will as the source of our responsibility [Epictetus, by Frede,M] |
Full Idea: The notion of will in Epictetus is clearly developed to pinpoint the source of our responsibility for our actions and to identify precisely what it is that makes them our own doings. | |
From: report of Epictetus (The Discourses [c.56]) by Michael Frede - A Free Will 3 | |
A reaction: So the key move is that responsibility needs a 'source', rather than being a generalisation about how our actions arise. The next step is demand an 'ultimate' source, and this leads to the idea that this new will is 'free'. This will can be good or bad. |
20873 | Tragedies are versified sufferings of people impressed by externals [Epictetus] |
Full Idea: Tragedies are nothing but the sufferings of people who are impressed by externals, performed in the right sort of meter. | |
From: Epictetus (The Discourses [c.56], 1.04.26) | |
A reaction: The externals are things like honour, position and wealth. Wonderfully dismissive! |
23364 | Homer wrote to show that the most blessed men can be ruined by poor judgement [Epictetus] |
Full Idea: Did not Homer write to show us that the noblest, the strongest, the richest, the handsomest of men may nevertheless be the most unfortunate and wretched, if they do not hold the judgements that they ought to hold? | |
From: Epictetus (The Discourses [c.56], 4.10.36) | |
A reaction: This seems to be right. He clearly wrote about the greatest and most memorable events of recent times, but not just to record triumphs, because almost every hero (in the Iliad, at least) ends in disaster. |
23340 | We consist of animal bodies and god-like reason [Epictetus] |
Full Idea: We have these two elements mingled within us, a body in common with the animals, and reason and intelligence in common with the gods. | |
From: Epictetus (The Discourses [c.56], 1.03.03) | |
A reaction: This is what I call Human Exceptionalism, but note that it doesn't invoke a Christian soul or spiritual aspect. This separation of reason goes back at least to Plato. High time we stopped thinking this way. Animals behave very sensibly. |
23358 | Every species produces exceptional beings, and we must just accept their nature [Epictetus] |
Full Idea: In every species nature produces some exceptional being, in oxen, in dogs, in bees, in horses. We do not say to them 'Who are you?' It will tell you 'I am like the purple in the robe. Do not expect me to be like the rest, or find fault with my nature'. | |
From: Epictetus (The Discourses [c.56], 3.01.23) | |
A reaction: This idea began with Aristotle's 'great soul', and presumably culminates in Nietzsche, who fills in more detail. In the modern world such people are mostly nothing but trouble. |
23339 | I will die as becomes a person returning what he does not own [Epictetus] |
Full Idea: When the time comes, then I will die - as becomes a person who gives back what is not his own. | |
From: Epictetus (The Discourses [c.56], 1.01.32) | |
A reaction: There is a tension between his demand that he have full control of his choices, and this humility that says his actual life is not his own. The things which can't be controlled, though, are 'indifferents' so life and death are indifferent. |
23345 | Don't be frightened of pain or death; only be frightened of fearing them [Epictetus] |
Full Idea: It is not pain or death that is to be feared, but the fear of pain or death. | |
From: Epictetus (The Discourses [c.56], 2.01.13) | |
A reaction: These two cases are quite different, I would say. I'm much more frightened of pain than I am of the fear of pain, and the opposite view seems absurd. About death, though, I think this is right. Mostly I'm with Spinoza: think about life, not death. |
23357 | Knowledge of what is good leads to love; only the wise, who distinguish good from evil, can love [Epictetus] |
Full Idea: Whoever has knowledge of good things would know how to love them; and how could he who cannot distinguish good things from evil still have to power to love? It follows that the wise man alone has the power to love. | |
From: Epictetus (The Discourses [c.56], 2.22.03) | |
A reaction: A rather heartwarming remark, but hard to assess for its truth. Evil people are unable to love? Not even love a cat, or their favourite car? We would never call someone wise if they lacked love. |
23363 | The evil for everything is what is contrary to its nature [Epictetus] |
Full Idea: Where is the paradox if we say that what is evil for everything is what is contrary to its nature? | |
From: Epictetus (The Discourses [c.56], 4.01.125) | |
A reaction: A very Greek view. For humans, it must rely on the belief that human nature is essentially good. If I am sometimes grumpy and annoying, why is that not part of my nature? |
23328 | The essences of good and evil are in dispositions to choose [Epictetus] |
Full Idea: The essence of the good is a certain disposition of our choice, and essence of evil likewise. | |
From: Epictetus (The Discourses [c.56], 1.29.01) | |
A reaction: This is the origin of Kant's famous view, that the only true good is a good will. This is the alternative to good character or good states of affairs as the good. It points towards the modern more legalistic view of morality, as concerning actions. |
23362 | All human ills result from failure to apply preconceptions to particular cases [Epictetus] |
Full Idea: The cause of all human ills is that people are incapable of applying their general preconceptions to particular cases. | |
From: Epictetus (The Discourses [c.56], 4.01.42) | |
A reaction: I'm not sure whether 'preconceptions' is meant pejoratively (as unthinking, and opposed to true principles). This sounds like modern particularism (e.g. Jonathan Dancy) to the letter. |
23353 | We have a natural sense of honour [Epictetus] |
Full Idea: What faculty do you mean? - Have we not a natural sense of honour? - We have. | |
From: Epictetus (The Discourses [c.56], 2.10.22) | |
A reaction: This seems unlikely, given the lower status that honour now has with us, compared to two hundred years ago. But there may be a natural sense of status, and of humiliation and shame. |
23354 | If someone harms themselves in harming me, then I harm myself by returning the harm [Epictetus] |
Full Idea: Since he has harmed himself by wronging me, shall not I harm myself by harming him? | |
From: Epictetus (The Discourses [c.56], 2.10.26) | |
A reaction: I am very keen on this idea. See Hamlet's remarks to Polonius about 'honour and dignity'. The best strategy for achieving moral excellence is to focus on our own characters, rather than how to act, and to respond to others. |
23324 | In the Discourses choice [prohairesis] defines our character and behaviour [Epictetus, by Frede,M] |
Full Idea: In Epictetus's 'Discourses' the notion of choice [prohairesis] plays perhaps the central role. It is our prohairesis which defines us a person, as the sort of person we are; it is our prohairesis which determines how we behave. | |
From: report of Epictetus (The Discourses [c.56]) by Michael Frede - A Free Will 3 | |
A reaction: Frede is charting the gradual move in Greek philosophy from action by desire, reason and habit to action by the will (which then turns out to be 'free'). Character started as dispositions and ended as choices. |
23361 | Health is only a good when it is used well [Epictetus] |
Full Idea: Is health a good and sickness an evil? No. Health is good when used well, and bad when used ill. | |
From: Epictetus (The Discourses [c.56], 3.20.04) | |
A reaction: Although I like the idea that health is a natural value, which bridges the gap from facts to values (as a successful function), there is no denying that the health of very evil people is not something the rest of us hope for. |
23346 | A person is as naturally a part of a city as a foot is part of the body [Epictetus] |
Full Idea: Just as the foot in detachment is no longer a foot, so you in detachment are not longer a man. For what is a man? A part of a city, first. | |
From: Epictetus (The Discourses [c.56], 2.05.26) | |
A reaction: It is, of course, not true that a detached foot ceases to be a foot (and an isolated human is still a human). This an extreme version of the Aristotelian idea that we are essentially social. It is, though, the sort of view favoured by totalitarianism. |
23351 | We are citizens of the universe, and principal parts of it [Epictetus] |
Full Idea: You are a citizen of the universe, and a part of it; and no subservient, but a principal part of it. | |
From: Epictetus (The Discourses [c.56], 2.10.03) | |
A reaction: He got this view from Diogenes of Sinope, one of his heroes. What community you are a part of seems to be a choice as much as a fact. Am I British or a European? |
20874 | A citizen is committed to ignore private advantage, and seek communal good [Epictetus] |
Full Idea: The commitment of the citizen is to have no private advantage, not to deliberate about anything as though one were a separate part. | |
From: Epictetus (The Discourses [c.56], 2.10.04) | |
A reaction: This is the modern problem of whether democratic voters are choosing for themselves or for the community. I think we should make an active effort at every election to persuade voters to aim for the communal good. Cf Rawls. |
23352 | A citizen should only consider what is good for the whole society [Epictetus] |
Full Idea: The calling of a citizen is to consider nothing in terms of personal advantage, never to deliberate on anything as though detached from the whole, but be like our hand or foot. | |
From: Epictetus (The Discourses [c.56], 2.10.04) | |
A reaction: Fat chance of that in an aggressively capitalist society. I've always voted for what I thought was the common good, and was shocked to gradually realise that many people only vote for what promotes their own interests. Heigh ho. |
22604 | Punishing a criminal for moral ignorance is the same as punishing someone for being blind [Epictetus] |
Full Idea: You should ask 'Ought not this man to be put to death, who is deceived in things of the greatest importance, and is blinded in distinguishing good from evil?' …You then see how inhuman it is, and the same as 'Ought not this blind man to be put to death?' | |
From: Epictetus (The Discourses [c.56], 1.18.6-7) | |
A reaction: This is the doctrine of Socrates, that evil is ignorance (and weakness of will [akrasia] is impossible). Epictetus wants us to reason with the man, but what should be do if reasoning fails and he persists in his crimes? |
23349 | Asses are born to carry human burdens, not as ends in themselves [Epictetus] |
Full Idea: An ass is surely not born as an end in itself? No, but because we had need of a back that is able to carry burdens. | |
From: Epictetus (The Discourses [c.56], 2.08.07) | |
A reaction: This is the absurd human exceptionalism which plagues our thinking. It would be somewhat true of animals which are specifically bred for human work, such as large cart horses. |
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. |
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. |
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'. |
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. |
18970 | The concept of a 'point' makes no sense without the idea of absolute position [Quine] |
Full Idea: Unless we are prepared to believe that absolute position makes sense, the very idea of a point as an entity in its own right must be rejected as not merely mysterious but absurd. | |
From: Willard Quine (Propositional Objects [1965], p.149) | |
A reaction: The fact that without absolute position we can only think of 'points' as relative to a conceptual grid doesn't stop the grid from picking out actual locations in space, as shown by latitude and longitude. |
23341 | God created humans as spectators and interpreters of God's works [Epictetus] |
Full Idea: God has introduced man into the world as a spectator of himself and of his works: and not only as a spectator of them, but an interpreter of them as well. | |
From: Epictetus (The Discourses [c.56], 1.06.19) | |
A reaction: This idea (which strikes me as bizarre) was picked up directly by the Christians. I can't imagine every Johnson wanting to creating their own Boswell. If you think we are divinely created, you have to propose some motive for it, I suppose. |
23348 | Both god and the good bring benefits, so their true nature seems to be the same [Epictetus] |
Full Idea: God brings benefits; but the good also brings benefit. It would seem, then, that where the true nature of god is, there too is the true nature of good. | |
From: Epictetus (The Discourses [c.56], 2.08.01) | |
A reaction: An enthymeme, missing the premise that there can only be one source of benefit (which sounds unlikely). Does god bring anything other than benefits? And does the good? I think this is an idea from later platonism. |
23360 | Each of the four elements in you is entirely scattered after death [Epictetus] |
Full Idea: Whatever was in you of fire, departs into fire; what was of earth, into earth; what of air, into air; what of water, into water. There is no Hades, nor Acheron. | |
From: Epictetus (The Discourses [c.56], 3.13.15) | |
A reaction: This sort of remark may explain why so few of the great Stoic texts (such as those of Chrysippus) survived the Christian era. |
