| 3811 | Entailment and validity are relations, but inference is a human activity [Searle] |
| Full Idea: We must distinguish between entailment and validity as logical relations on the one hand, and inferring as a voluntary human activity on the other. | |
| From: John Searle (Rationality in Action [2001], Ch.1.II) |
| 3822 | Theory involves accepting conclusions, and so is a special case of practical reason [Searle] |
| Full Idea: Theoretical reason is typically a matter of accepting a conclusion or hypothesis on the basis of argument or evidence, and is thus a special case of practical reason. | |
| From: John Searle (Rationality in Action [2001], Ch.3.VII) |
| 3806 | Rationality is built into the intentionality of the mind, and its means of expression [Searle] |
| Full Idea: Constraints of rationality are built into the structure of mind and language, specifically into the structure of intentionality and speech acts. | |
| From: John Searle (Rationality in Action [2001], Int xiv) |
| 3812 | Rationality is the way we coordinate our intentionality [Searle] |
| Full Idea: The constraints of rationality ought to be thought of adverbially; they are a matter of the way in which we coordinate our intentionality. | |
| From: John Searle (Rationality in Action [2001], Ch.1.II) |
| 3809 | If complex logic requires rules, then so does basic logic [Searle] |
| Full Idea: If you think you need a rule to infer q from 'p and (if p then q)', then you would also need a rule to infer p from p. | |
| From: John Searle (Rationality in Action [2001], Ch.1.II) |
| 21495 | Theoretical and practical politics are both concerned with the best lives for individuals [Russell] |
| Full Idea: Political ideals must be based upon ideals for the individual life. The aim of politics should be to make the lives of individuals as good as possible. | |
| From: Bertrand Russell (Political Ideals [1917], 1) | |
| A reaction: Russell floats between socialism and anarchism, but this foundational remark is classic liberalism. |
| 3810 | In real reasoning semantics gives validity, not syntax [Searle] |
| Full Idea: In real-life reasoning it is the semantic content that guarantees the validity of the inference, not the syntactical rule. | |
| From: John Searle (Rationality in Action [2001], Ch.1.II) |
| 3841 | Users of 'supervenience' blur its causal and constitutive meanings [Searle] |
| Full Idea: I am no fan of the concept of supervenience. Its uncritical use is a sign of philosophical confusion, because the concept oscillates between causal supervenience and constitutive supervenience. | |
| From: John Searle (Rationality in Action [2001], Ch.9 n5) | |
| A reaction: I don't see why you shouldn't assert the supervenience of one thing on another, while saying that you are not sure whether it is causal or constitutive. The confusion seems to me to be in understandings of the causal version. |
| 17377 | All descriptive language is classificatory [Dupré] |
| Full Idea: Classification pervades any descriptive use of language whatever. | |
| From: John Dupré (The Disorder of Things [1993], 1) | |
| A reaction: This is because, as Aristotle well knew, language consists almost entirely of universals (apart from the proper names). Language just is classification. |
| 17376 | We should aim for a classification which tells us as much as possible about the object [Dupré] |
| Full Idea: The most important desideratum of a classificatory scheme is that assigning an object to a particular classification tell us as much as possible about that object. | |
| From: John Dupré (The Disorder of Things [1993], Ch 1) | |
| A reaction: We should probably say that the aim is a successful explanation, rather than a heap of information. If we are totally baffled by a particular type of object, it is presumably important to group the instances together, to focus the bafflement. |
| 17390 | Natural kinds don't need essentialism to be explanatory [Dupré] |
| Full Idea: The importance of natural kinds for explanation does not depend on a doctrine of essences. | |
| From: John Dupré (The Disorder of Things [1993], 3) | |
| A reaction: He suggest as the alternative that laws do the explaining, employing natural kinds. He allows that individual essences might be explanatory. |
| 17389 | A species might have its essential genetic mechanism replaced by a new one [Dupré] |
| Full Idea: Contradicting one of the main points of essentialism, there is no reason in principle why a species should not survive the demise of its current genetic mechanisms (some other species coherence gradually taking over). | |
| From: John Dupré (The Disorder of Things [1993], 2) | |
| A reaction: I would say that this meant that the species had a new essence, because I don't take what is essential to be the same as what is necessary. The new genetics would replace the old as the basic explanation of the species. |
| 17388 | It seems that species lack essential properties, so they can't be natural kinds [Dupré] |
| Full Idea: It is widely agreed among biologists that no essential property can be found to demarcate species, so that if an essential property is necessary for a natural kind, species are not natural kinds. | |
| From: John Dupré (The Disorder of Things [1993], 2) | |
| A reaction: This uses 'essential' to mean 'necessary', but I would use 'essential' to mean 'deeply explanatory'. Biological species are, nevertheless, dubious members of an ontological system. Vegetables are the problem. |
| 3816 | Our beliefs are about things, not propositions (which are the content of the belief) [Searle] |
| Full Idea: The terminology of "propositional attitudes" is confused, because it suggests that a belief is an attitude towards a propositions, …but the proposition is the content, not the object, of my belief. | |
| From: John Searle (Rationality in Action [2001], Ch.2) |
| 3833 | A belief is a commitment to truth [Searle] |
| Full Idea: A belief is a commitment to truth. | |
| From: John Searle (Rationality in Action [2001], Ch.4.III) |
| 3837 | We can't understand something as a lie if beliefs aren't commitment to truth [Searle] |
| Full Idea: If I lie and say "It is raining", my utterance is intelligible to me as a lie precisely because I understand that the utterance commits me to the truth of a proposition I do not believe to be true. | |
| From: John Searle (Rationality in Action [2001], Ch.6.II) |
| 3828 | Thinking must involve a self, not just an "it" [Searle] |
| Full Idea: We should not say "It thinks" in preference to "I think". If thinking is an active, voluntary process, there must be a self who thinks. | |
| From: John Searle (Rationality in Action [2001], Ch.3.IX) |
| 3831 | Reasons can either be facts in the world, or intentional states [Searle] |
| Full Idea: Both reasons and the things they are reasons for can be either facts in the world or intentional states such as beliefs, desires, and intentions. | |
| From: John Searle (Rationality in Action [2001], Ch.4.I) | |
| A reaction: One might point out that beliefs, desires and intentions are facts in the world too. Implicit dualism. One can ask, what turns a fact into a reason? |
| 3830 | In the past people had a reason not to smoke, but didn't realise it [Searle] |
| Full Idea: For a long time people had a reason not to smoke cigarettes, without knowing that they had such a reason. | |
| From: John Searle (Rationality in Action [2001], Ch.4) | |
| A reaction: What does 'had' a reason mean here? If I wish you dead, there is a reason why you should be dead, but you don't 'have' the reason, and never will have. There's probably a reason why I should never have been born. |
| 3832 | Causes (usually events) are not the same as reasons (which are never events) [Searle] |
| Full Idea: Causes are typically events, reasons are never events. You can give a reason by stating a cause, but it does not follow that the reason and the cause are the same thing. | |
| From: John Searle (Rationality in Action [2001], Ch.4.I) | |
| A reaction: This is against Davidson. I'm with Searle here; my having a reason to do something is not the cause of my doing it. I don't, unlike Searle, believe in free will, but doing something for a reason is not just the operation of the reason. |
| 17374 | The possibility of prediction rests on determinism [Dupré] |
| Full Idea: Determinism is the metaphysical underlay of the possibility of prediction. | |
| From: John Dupré (The Disorder of Things [1993], Intro) | |
| A reaction: Not convinced. There might be micro-indeterminacies which iron out into macro-regularities. |
| 3823 | Being held responsible for past actions makes no sense without personal identity [Searle] |
| Full Idea: I am held responsible now for things that I did in the distant past. But that only makes sense if there is some entity that is both the agent of the action in the past and me now. | |
| From: John Searle (Rationality in Action [2001], Ch.3.VII) | |
| A reaction: A possible response, of course, is that you are held responsible for your past deeds, but you shouldn't be. The idea that you are the same as when you committed the crime is a convenient fiction for people who desire revenge. Responsibility fades. |
| 3821 | Giving reasons for action requires reference to a self [Searle] |
| Full Idea: The requirement that I state reasons that I acted on requires a reference to the self. …Only for a self can something be a reason for an action. | |
| From: John Searle (Rationality in Action [2001], Ch.3.VII) | |
| A reaction: Why can't we just say that this reason, given this desire and this belief, led to this action, and never mention the self? Admittedly leaving out 'I' is an odd circumlocution, but I don't find this particular argument very convincing. |
| 3824 | A 'self' must be capable of conscious reasonings about action [Searle] |
| Full Idea: In order to be a self the entity that acts as an agent must also be capable of conscious reasoning about its actions. | |
| From: John Searle (Rationality in Action [2001], Ch.3.VIII) | |
| A reaction: I can't accept this all-or-nothing account. A chimpanzee is some sort of 'agent', and there are bad chimpanzees you wouldn't want in your colony. Why does Searle want to cut us off in some special compound where our actions are totally different? |
| 3834 | An intentional, acting, rational being must have a self [Searle] |
| Full Idea: Selfhood in my sense comes for free once you have a conscious intentional being capable of engaging in free actions on the basis of reasons. | |
| From: John Searle (Rationality in Action [2001], Ch.5.II) | |
| A reaction: The concept of an 'action' is probably the thing that most clearly needs a self, because it implies co-ordination and purpose, and there must be some item which benefits. Personally I think you can drop 'free actions' and still have a self. |
| 3825 | Action requires a self, even though perception doesn't [Searle] |
| Full Idea: It is a formal requirement on rational action that there must be a self who acts, in a way that it is not a formal requirement on perception that there be an agent or a self who perceives. | |
| From: John Searle (Rationality in Action [2001], Ch.3.IX) | |
| A reaction: I don't find this persuasive. I don't see how we can rule out a priori the possibility of a set of desires and reasons within an organism which generate an action, without any intervening 'self' to add something. Ockham's Razor. |
| 3829 | Selfs are conscious, enduring, reasonable, active, free, and responsible [Searle] |
| Full Idea: A self is conscious, persists through time, operates with reasons, carries out free actions, and is responsible. | |
| From: John Searle (Rationality in Action [2001], Ch.3.X) | |
| A reaction: Personally I would substitute 'makes decisions' for 'carries out free actions', but otherwise I agree, though he seems to miss a key aspect, which is that the self is in charge of the mind, and directs its focus and co-ordinates its inputs and outputs. |
| 3826 | A self must at least be capable of consciousness [Searle] |
| Full Idea: The first condition on the self is that it should be capable of consciousness. | |
| From: John Searle (Rationality in Action [2001], Ch.3.IX) | |
| A reaction: This strikes me as a stipulative definition. It raises the question of whether it is possible that a lizard (say) is not actually conscious, but has some sort of propriotreptic awareness, and a 'central controller' for its decision-making. |
| 3827 | The self is neither an experience nor a thing experienced [Searle] |
| Full Idea: The self is not an experience, nor is it an object that is experienced. | |
| From: John Searle (Rationality in Action [2001], Ch.3.IX) | |
| A reaction: A nice dichotomy, that draws attention to the unique position of the self. Thanks to Descartes for focusing our attention on it. Personally I would say that the self is an object, which cannot be experienced by itself, but can be inferred by others. |
| 3820 | The bundle must also have agency in order to act, and a self to act rationally [Searle] |
| Full Idea: Agency must be added to the bundle to account for how embodied bundles engage in free actions, and selfhood must be added to account for how agents can act rationally. | |
| From: John Searle (Rationality in Action [2001], Ch.3.VII) | |
| A reaction: I don't buy much of this, but I am inclined to say that a will must be added to the bundle to explain why it acts consistently and coherently. It is certainly ridiculous to rest with the picture of a person as a completely unstructured bundle. |
| 3808 | Rational decision making presupposes free will [Searle] |
| Full Idea: In order to engage in rational decision making we have to presuppose free will. | |
| From: John Searle (Rationality in Action [2001], Ch.1.II) |
| 3818 | We freely decide whether to make a reason for action effective [Searle] |
| Full Idea: Where free rational action is concerned, all effective reasons are made effective by the agent. | |
| From: John Searle (Rationality in Action [2001], Ch.3.II) |
| 3817 | Free will is most obvious when we choose between several reasons for an action [Searle] |
| Full Idea: The most dramatic manifestation of the free will gap is that when one has several reasons for performing an action, one may act on only one of them; one may select which reason one acts on. | |
| From: John Searle (Rationality in Action [2001], Ch.3.II) |
| 17378 | Presumably molecular structure seems important because we never have the Twin Earth experience [Dupré] |
| Full Idea: It is surely the absence of experiences like the one Putnam describes that makes it reasonable to attach to molecular structure at least most of the importance that Putnam ascribes to it. | |
| From: John Dupré (The Disorder of Things [1993], 1) | |
| A reaction: That is, whenever we experience water-like stuff, it always turns out to have the same molecular structure. Twin Earth is a nice thought experiment, except that XZY is virtually inconceivable. |
| 3814 | Preferences can result from deliberation, not just precede it [Searle] |
| Full Idea: A well-ordered set of preferences is typically the result of successful deliberation, and is not its precondition. | |
| From: John Searle (Rationality in Action [2001], Ch.1.II) |
| 3840 | We don't accept practical reasoning if the conclusion is unpalatable [Searle] |
| Full Idea: If I desire to get rid of my flu symptoms, and believe the only way to do it is death, I am committed to desiring my death. …there is no plausible logic of practical reason. | |
| From: John Searle (Rationality in Action [2001], Ch.8.II) |
| 3815 | The essence of humanity is desire-independent reasons for action [Searle] |
| Full Idea: The single greatest difference between humans and other animals as far as rationality is concerned is our ability to create, recognise and act on desire-independent reasons for action. | |
| From: John Searle (Rationality in Action [2001], Ch.1.II) |
| 3839 | Only an internal reason can actually motivate the agent to act [Searle] |
| Full Idea: Only an internal reason can actually motivate the agent to act. | |
| From: John Searle (Rationality in Action [2001], Ch.6 App) |
| 3835 | If it is true, you ought to believe it [Searle] |
| Full Idea: To say that something is true is already to say that you ought to believe it. | |
| From: John Searle (Rationality in Action [2001], Ch.5.II) | |
| A reaction: I'm sure what Einstein said is true, but I don't understand it. The truth is the thought of how things actually are, but why should I not prefer my private fantasies? I see the point, though. |
| 3836 | If this is a man, you ought to accept similar things as men [Searle] |
| Full Idea: From the fact that an object is truly described as "a man", it follows that you ought to accept relevantly similar objects as men. | |
| From: John Searle (Rationality in Action [2001], Ch.5.IV) | |
| A reaction: 'Similar' rather begs the question. Common speech distinguishes sharply between a man and a 'real man'. You only accept them as men if you see them as men, not as similar to something else. Interesting. |
| 3838 | Promises hold because I give myself a reason, not because it is an institution [Searle] |
| Full Idea: The obligation to keep a promise does not derive from the institution of promising, ..but from the fact that in promising I freely and voluntarily create a reason for myself. | |
| From: John Searle (Rationality in Action [2001], Ch.6.IV) |
| 21517 | Individuals need creativity, reverence for others, and self-respect [Russell] |
| Full Idea: What we shall desire for individuals is now clear: strong creative impulses, overpowering and absorbing the instinct of possession; reverence for others; respect for the fundamental creative impulses in ourselves. | |
| From: Bertrand Russell (Political Ideals [1917], 1) | |
| A reaction: Interesting that when Russell focuses on morality, he turns to virtues, rather than to rules. He uses 'reverence' where I would favour 'respect'. His concept of creativity is broad, and does not just concern art etc. |
| 3813 | 'Ought' implies that there is a reason to do something [Searle] |
| Full Idea: To say that someone 'ought' to do something is to imply that there is a reason for him to do it. | |
| From: John Searle (Rationality in Action [2001], Ch.1.II) |
| 21523 | We would not want UK affairs to be settled by a world parliament [Russell] |
| Full Idea: We should none of us like the affairs of Great Britain to be settled by a parliament of the world. | |
| From: Bertrand Russell (Political Ideals [1917], 1) | |
| A reaction: The UK is currently (Dec 2018) living with a plan to quit Europe, mainly on the grounds that a European parliament has some authority over Britain. In every country resentment of the government increases with distance from the capital city. |
| 21522 | Democracy is inadequate without a great deal of devolution [Russell] |
| Full Idea: Democracy is not at all an adequate device unless it is accompanied by a very great amount of devolution. | |
| From: Bertrand Russell (Political Ideals [1917], 1) | |
| A reaction: This whole book of Russell's is an appeal for the devolution of power, and for workplace democracy. |
| 21521 | Anarchy does not maximise liberty [Russell] |
| Full Idea: The greatest degree of liberty is not secured by anarchy. ...[22] The results of anarchy between states should suffice to persuade us that anarchism has no solution to offer for the evils of the world. | |
| From: Bertrand Russell (Political Ideals [1917], 1) | |
| A reaction: I've heard Russell described as an anarchist, but this clearly wasn't true in 1917. Presumably liberty has to be protected. That we were watching anarchy between states in 1917 is a vivid observation. |
| 21528 | Groups should be autonomous, with a neutral authority as arbitrator [Russell] |
| Full Idea: For maximum freedom with minimum force: Autonomy within each politically important group, and a neutral authority for deciding questions involving relations between groups. | |
| From: Bertrand Russell (Political Ideals [1917], 3) | |
| A reaction: This is workplace democracy, and also considerable self-rule amongst minority groups such as religions. |
| 21527 | On every new question the majority is always wrong at first [Russell] |
| Full Idea: It is a mistake to suppose that the majority is necessarily right. On every new question the majority is always wrong at first. | |
| From: Bertrand Russell (Political Ideals [1917], 3) | |
| A reaction: Sounds like bitter experience. This is a good argument for taking time over decisions, and (topical) for a second referendum some time after the first one (if you must have a referendum). |
| 21526 | Unfortunately ordinary voters can't detect insincerity [Russell] |
| Full Idea: It is a painful fact that the ordinary voter, at any rate in England, is quite blind to insincerity. | |
| From: Bertrand Russell (Political Ideals [1917], 3) | |
| A reaction: Gor blimey yes! Well said, Bertie. Even in the age of television, when you can examine them in closeup, people seem to confuse superficial charm with genuine positive convictions. Why are people better at detecting it in private life? |
| 21525 | When the state is the only employer, there is no refuge from the prejudices of other people [Russell] |
| Full Idea: Under state socialism ...where the State is the only employer, there is no refuge from its prejudices such as may now accidentally arise through the differing opinions of men. | |
| From: Bertrand Russell (Political Ideals [1917], 2) | |
| A reaction: There is also a strong likelihood in full state socialism that the state will control housing as well as employment. This hadn't come to pass in 1917. |
| 21518 | Men unite in pursuit of material things, and idealise greed as part of group loyalty [Russell] |
| Full Idea: Men combine in groups to attain more strength in the scramble for material goods, and loyalty to the group spreads a halo of quasi-idealism round the central impulse of greed. | |
| From: Bertrand Russell (Political Ideals [1917], 1) | |
| A reaction: See the 'greed is good' speech in the film 'Wall Street'. This sounds like a description of the USA, but Russell was very much in England at this stage. |
| 21519 | We need security and liberty, and then encouragement of creativity [Russell] |
| Full Idea: Security and liberty are only the negative conditions for good political institutions. When they have been won, we need also the positive condition: encouragement of creative energy. | |
| From: Bertrand Russell (Political Ideals [1917], 1) | |
| A reaction: This sounds like some sort of liberal socialism. The nearest connection I can see is to the 'capabilities approach' of Martha Nussbaum. How do you intervene to encourage creativity? |
| 21524 | The right to own land gives a legal right to a permanent income [Russell] |
| Full Idea: There are many ways of becoming rich without contributing anything to the wealth of the community. Ownership of land or capital, whether acquired or inherited, gives a legal right to a permanent income. | |
| From: Bertrand Russell (Political Ideals [1917], 2) | |
| A reaction: I suspect that in the past land was the main source of this right, but now it is more likely to be capital. Land carries obligations of some sort, so income from capital is more fun. |
| 17381 | Phylogenetics involves history, and cladism rests species on splits in lineage [Dupré] |
| Full Idea: The phylogenetic conception of classification reflects the facts of evolutionary history. Cladism insists that every taxonomic distinction should reflect an evolutionary event of lineage bifurcation. | |
| From: John Dupré (The Disorder of Things [1993], 1) | |
| A reaction: Devitt attacks cladism nicely. It rules out species change without bifurcation, and it insists on species change even in a line which remains unchanged after a split. |
| 17385 | Kinds don't do anything (including evolve) because they are abstract [Dupré] |
| Full Idea: A kind, being an abstract object, cannot do anything, including evolve. | |
| From: John Dupré (The Disorder of Things [1993], 2) | |
| A reaction: Maybe. We might have an extensional view of the kind, so that 'gold' is the set of extant gold atoms. But possible gold atoms are also gold, and defunct ones too. Virtually every word in English is abtract if you think about it long enough. |
| 17375 | Natural kinds are decided entirely by the intentions of our classification [Dupré] |
| Full Idea: The question of which natural kind a thing belongs to ....can be answered only in relation to some specification of the goal underlying the intent to classify the object. | |
| From: John Dupré (The Disorder of Things [1993], Intro) | |
| A reaction: I don't think I believe this. The situation is complex, and our intents are relevant, but to find an intent which no longer classifies tigers into the same category is wilful silliness. |
| 17379 | Borders between species are much less clear in vegetables than among animals [Dupré] |
| Full Idea: The richest source of illustrations is the vegetable kingdom, where specific differences tend to be much less clear than among animals, and considerable developmental plasticity is the rule. | |
| From: John Dupré (The Disorder of Things [1993], 1) | |
| A reaction: Nice. Just as the idea that laws of nature are mathematical suits physics, but founders on biology, so natural kinds founder in an area of biology to which we pay less attention. He cites prickly pears and lilies. I'm thinking oranges, satsumas etc. |
| 17384 | Even atoms of an element differ, in the energy levels of their electrons [Dupré] |
| Full Idea: Even if we claim that it is really isotopes not atoms that are the natural kinds (thus divorcing chemistry from ordinary language), atoms are said to differ with respect to such features as energy levels of the electrons. | |
| From: John Dupré (The Disorder of Things [1993], 2) | |
| A reaction: So we can't just pick out the features of one atom, and say that is the essence. Essence always involves some selection. I say the essence arises from the explanation of the atom's behaviour. |
| 17387 | Ecologists favour classifying by niche, even though that can clash with genealogy [Dupré] |
| Full Idea: To the extent that the occupants of a particular niche do not coincide with the members of a particular genealogical line, a possibility widely acknowledged to occur, ecologists must favour a method of classification lacking genealogical grounding. | |
| From: John Dupré (The Disorder of Things [1993], 2) | |
| A reaction: Zoo keepers probably classify by cages, or which zoo owns what, but that doesn't mean that they reject genealogy. Don't assume ecologists are rejecting any underlying classification that differs from theirs. Compare classification by economists. |
| 17382 | Cooks, unlike scientists, distinguish garlic from onions [Dupré] |
| Full Idea: It would be a severe culinary misfortune if no distinction were drawn between garlic and onions, a distinction that is not reflected in scientific taxonomy. | |
| From: John Dupré (The Disorder of Things [1993], 1) | |
| A reaction: Not every persuasive. We distinguish some cows from others because they taste better, but no one thinks that is a serious way in which to classify cows. |
| 17380 | Wales may count as fish [Dupré] |
| Full Idea: The claim that whales are not fish is a debatable one | |
| From: John Dupré (The Disorder of Things [1993], 1) | |
| A reaction: A very nice challenge to an almost unquestioned orthodoxy. |
| 17383 | Species are the lowest-level classification in biology [Dupré] |
| Full Idea: Species are, by definition, the lowest-level classificatory unit, or basal taxonomic unit, for biological organisms. | |
| From: John Dupré (The Disorder of Things [1993], 2) | |
| A reaction: I think this is the 'infima species' for Aristotelians. What about 'male' and 'female' in each species? |
| 17386 | The theory of evolution is mainly about species [Dupré] |
| Full Idea: Species are what the theory of evolution is centrally about. | |
| From: John Dupré (The Disorder of Things [1993], 2) |
| 21520 | That our heaven is a dull place reflects the misery of excessive work in life [Russell] |
| Full Idea: It is a sad evidence of the weariness mankind has suffered from excessive toil that his heavens have usually been places where nothing ever happened or changed. | |
| From: Bertrand Russell (Political Ideals [1917], 1) | |
| A reaction: Has any religion got an idea of heaven as a place full of lively activity and creative problem-solving? That is what suits us best. |
