| 13939 | No possible evidence could decide the reality of numbers, so it is a pseudo-question [Carnap] |
| Full Idea: I cannot think of any possible evidence that would be regarded as relevant by both nominalists and realists about numbers, and would decide the controversy, or make one side more probable. Hence I regard the external questions as pseudo-questions. | |
| From: Rudolph Carnap (Empiricism, Semantics and Ontology [1950], 4) |
| 16252 | Metaphysics uses empty words, or just produces pseudo-statements [Carnap] |
| Full Idea: Since metaphysics doesn't want to assert analytic propositions, nor fall within the domain of physical science, it is compelled to employ words for which no criteria of application are specified, ..or else combine meaningful words..into pseudo-statements. | |
| From: Rudolph Carnap (Elimination of Metaphysics by Analysis of Language [1959]), quoted by Tim Maudlin - The Metaphysics within Physics 2.4 | |
| A reaction: A classic summary of the logical positivist rejection of metaphysics. I incline to treat metaphysics as within the domain of science, but at a level of generality so high that practising scientists become bewildered and give up. |
| 13342 | Carnap defined consequence by contradiction, but this is unintuitive and changes with substitution [Tarski on Carnap] |
| Full Idea: Carnap proposed to define consequence as 'sentence X follows from the sentences K iff the sentences K and the negation of X are contradictory', but 1) this is intuitively impossible, and 2) consequence would be changed by substituting objects. | |
| From: comment on Rudolph Carnap (The Logical Syntax of Language [1934], p.88-) by Alfred Tarski - The Concept of Logical Consequence p.414 | |
| A reaction: This seems to be the first step in the ongoing explicit discussion of the nature of logical consequence, which is now seen by many as the central concept of logic. Tarski brings his new tool of 'satisfaction' to bear. |
| 13251 | Each person is free to build their own logic, just by specifying a syntax [Carnap] |
| Full Idea: In logic, there are no morals. Everyone is at liberty to build his own logic, i.e. his own form of language. All that is required is that he must state his methods clearly, and give syntactical rules instead of philosophical arguments. | |
| From: Rudolph Carnap (The Logical Syntax of Language [1934], §17), quoted by JC Beall / G Restall - Logical Pluralism 7.3 | |
| A reaction: This is understandable, but strikes me as close to daft relativism. If I specify a silly logic, I presume its silliness will be obvious. By what criteria? I say the world dictates the true logic, but this is a minority view. |
| 13936 | Questions about numbers are answered by analysis, and are analytic, and hence logically true [Carnap] |
| Full Idea: For the internal question like 'is there a prime number greater than a hundred?' the answers are found by logical analysis based on the rules for the new expressions. The answers here are analytic, i.e., logically true. | |
| From: Rudolph Carnap (Empiricism, Semantics and Ontology [1950], 2) |
| 8748 | Logical positivists incorporated geometry into logicism, saying axioms are just definitions [Carnap, by Shapiro] |
| Full Idea: The logical positivists brought geometry into the fold of logicism. The axioms of, say, Euclidean geometry are simply definitions of primitive terms like 'point' and 'line'. | |
| From: report of Rudolph Carnap (Empiricism, Semantics and Ontology [1950]) by Stewart Shapiro - Thinking About Mathematics 5.3 | |
| A reaction: If the concept of 'line' is actually created by its definition, then we need to know exactly what (say) 'shortest' means. If we are merely describing a line, then our definition can be 'impredicative', using other accepted concepts. |
| 8960 | Internal questions about abstractions are trivial, and external ones deeply problematic [Carnap, by Szabó] |
| Full Idea: Carnap's verdict is that questions regarding the existence of abstracta tend to be trivial when taken as internal and deeply problematic when taken as external. | |
| From: report of Rudolph Carnap (Empiricism, Semantics and Ontology [1950]) by Zoltán Gendler Szabó - Nominalism 6 | |
| A reaction: If the internal aspect of the problem is 'trivial', this would put Carnap in league with fictionalists, who are only committed to entities while playing the current game. What is the status of the theory? Carnap wanted flowers to bloom. |
| 16062 | A necessary relation between fact-levels seems to be a further irreducible fact [Lynch/Glasgow] |
| Full Idea: It seems unavoidable that the facts about logically necessary relations between levels of facts are themselves logically distinct further facts, irreducible to the microphysical facts. | |
| From: Lynch,MP/Glasgow,JM (The Impossibility of Superdupervenience [2003], C) | |
| A reaction: I'm beginning to think that rejecting every theory of reality that is proposed by carefully exposing some infinite regress hidden in it is a rather lazy way to do philosophy. Almost as bad as rejecting anything if it can't be defined. |
| 16061 | If some facts 'logically supervene' on some others, they just redescribe them, adding nothing [Lynch/Glasgow] |
| Full Idea: Logical supervenience, restricted to individuals, seems to imply strong reduction. It is said that where the B-facts logically supervene on the A-facts, the B-facts simply re-describe what the A-facts describe, and the B-facts come along 'for free'. | |
| From: Lynch,MP/Glasgow,JM (The Impossibility of Superdupervenience [2003], C) | |
| A reaction: This seems to be taking 'logically' to mean 'analytically'. Presumably an entailment is logically supervenient on its premisses, and may therefore be very revealing, even if some people think such things are analytic. |
| 13933 | Existence questions are 'internal' (within a framework) or 'external' (concerning the whole framework) [Carnap] |
| Full Idea: We distinguish two kinds of existence questions: first, entities of a new kind within the framework; we call them 'internal questions'. Second, 'external questions', concerning the existence or reality of the system of entities as a whole. | |
| From: Rudolph Carnap (Empiricism, Semantics and Ontology [1950], 2) | |
| A reaction: This nicely disposes of many ontological difficulties, but at the price of labelling most external questions as meaningless, so that the internal answers have very little commitment, and the external (big) questions are now banned. Not for me. |
| 13934 | To be 'real' is to be an element of a system, so we cannot ask reality questions about the system itself [Carnap] |
| Full Idea: To be real in the scientific sense means to be an element of the system; hence this concept cannot be meaningfully applied to the system itself. | |
| From: Rudolph Carnap (Empiricism, Semantics and Ontology [1950], 2) |
| 16060 | Nonreductive materialism says upper 'levels' depend on lower, but don't 'reduce' [Lynch/Glasgow] |
| Full Idea: The root intuition behind nonreductive materialism is that reality is composed of ontologically distinct layers or levels. …The upper levels depend on the physical without reducing to it. | |
| From: Lynch,MP/Glasgow,JM (The Impossibility of Superdupervenience [2003], B) | |
| A reaction: A nice clear statement of a view which I take to be false. This relationship is the sort of thing that drives people fishing for an account of it to use the word 'supervenience', which just says two things seem to hang out together. Fluffy materialism. |
| 16064 | The hallmark of physicalism is that each causal power has a base causal power under it [Lynch/Glasgow] |
| Full Idea: Jessica Wilson (1999) says what makes physicalist accounts different from emergentism etc. is that each individual causal power associated with a supervenient property is numerically identical with a causal power associated with its base property. | |
| From: Lynch,MP/Glasgow,JM (The Impossibility of Superdupervenience [2003], n 11) | |
| A reaction: Hence the key thought in so-called (serious, rather than self-evident) 'emergentism' is so-called 'downward causation', which I take to be an idle daydream. |
| 13938 | A linguistic framework involves commitment to entities, so only commitment to the framework is in question [Carnap] |
| Full Idea: If someone accepts a framework for a kind of entities, then he must admit the entities as possible designata. Thus the question of the admissibility of entities is reduced to the question of the acceptability of the linguistic framework for the entities. | |
| From: Rudolph Carnap (Empiricism, Semantics and Ontology [1950], 4) | |
| A reaction: Despite the many differences of opinion between Quine and Carnap, this appears to be a straight endorsement by Carnap of the Quinean conception of ontological commitment. |
| 13935 | We only accept 'things' within a language with formation, testing and acceptance rules [Carnap] |
| Full Idea: To accept the thing world means nothing more than to accept a certain form of language, in other words, to accept rules for forming statements and for testing, accepting, or rejecting them. | |
| From: Rudolph Carnap (Empiricism, Semantics and Ontology [1950], 2) | |
| A reaction: If you derive your metaphysics from your language, then objects are linguistic conventions. But why do we accept conventions about objects? |
| 14305 | In the truth-functional account a burnt-up match was soluble because it never entered water [Carnap] |
| Full Idea: If a wooden match was completely burned up yesterday, and never placed in water at any time, is it not the case, therefore, that the match is soluble (in the truth-functional view). This follows just from the antecedent being false. | |
| From: Rudolph Carnap (Testability and Meaning [1937], I.440), quoted by Stephen Mumford - Dispositions | |
| A reaction: This, along with Edgington's nice example of the conditional command (Idea ) seems conclusive against the truth-functional account. The only defence possible is some sort of pragmatic account about implicature. |
| 13932 | Empiricists tend to reject abstract entities, and to feel sympathy with nominalism [Carnap] |
| Full Idea: Empiricists are in general rather suspicious with respect to any kind of abstract entities like properties, classes, relations, numbers, propositions etc. They usually feel more sympathy with nominalists than with realists (in the medieval sense). | |
| From: Rudolph Carnap (Empiricism, Semantics and Ontology [1950], 1) | |
| A reaction: The obvious reason is that you can't have sense experiences of abstract entities. I like the question 'what are they made of?' rather than the question 'how can I experience them?'. |
| 13937 | New linguistic claims about entities are not true or false, but just expedient, fruitful or successful [Carnap] |
| Full Idea: The acceptance of new linguistic forms about entities cannot be judged as being either true or false because it is not an assertion. It can only be judged as being more or less expedient, fruitful, conducive to the aim for which the language is intended. | |
| From: Rudolph Carnap (Empiricism, Semantics and Ontology [1950], 3) | |
| A reaction: The obvious problem seems to be that a complete pack of lies might be successful for a very long time, if it plugged a critical hole in a major theory. Is success judged financially? How do we judge success without mentioning truth? |
| 18699 | Carnap tried to define all scientific predicates in terms of primitive relations, using type theory [Carnap, by Button] |
| Full Idea: Carnap's ultimate ambition in the Aufbau is to provide a constitution-system within which any predicate of any scientific vocabulary can be explicitly defined in terms of primitive relations holding among basic elements, using type theory. | |
| From: report of Rudolph Carnap (The Logical Structure of the World (Aufbau) [1928]) by Tim Button - The Limits of Reason 05.2 | |
| A reaction: David Chalmers has a modern shot at the same project in 'Constructing the World'. Ramsey sentences seem to be part of the same game. |
| 13940 | All linguistic forms in science are merely judged by their efficiency as instruments [Carnap] |
| Full Idea: The acceptance or rejection of abstract (or any other) linguistic forms in any branch of science will finally be decided by their efficiency as instruments. | |
| From: Rudolph Carnap (Empiricism, Semantics and Ontology [1950], 5) |
| 13048 | Good explications are exact, fruitful, simple and similar to the explicandum [Carnap, by Salmon] |
| Full Idea: Carnap's four criteria for giving a good explication are similarity to the explicandum, exactness, fruitfulness and simplicity. | |
| From: report of Rudolph Carnap (Logical Foundations of Probability [1950], Ch.1) by Wesley Salmon - Four Decades of Scientific Explanation 0.1 | |
| A reaction: [compressed] Salmon's view is that this represents the old attitude, that the contribution of philosophy to explanation is the clarification of the key concepts. Carnap is, of course, a logical empiricist. |
| 12131 | All concepts can be derived from a few basics, making possible one science of everything [Carnap, by Brody] |
| Full Idea: In the 'Aufbau', Carnap tried to show how all of our concepts can be derived from a few basic concepts. ..Consequently there can be one science which studied all that existed, the science of the objects corresponding to the basic concepts. | |
| From: report of Rudolph Carnap (The Logical Structure of the World (Aufbau) [1928]) by Baruch Brody - Identity and Essence 2.2 | |
| A reaction: This is Carnap's Constructionist programme. |
| 11968 | The intension of a sentence is the set of all possible worlds in which it is true [Carnap, by Kaplan] |
| Full Idea: Carnap's proposal is to understand the category of intensions appropriate to sentences (his 'propositions') as sets of possible worlds. The intension of the sentence is taken as the set of all possible worlds in which the sentence is true. | |
| From: report of Rudolph Carnap (Meaning and Necessity [1947]) by David Kaplan - Transworld Heir Lines p.90 | |
| A reaction: [reference?] This extension of the truth-conditions view of meaning strikes me as being very attractive. Except that whole worlds hardly seem to be relevant to my remark about how lunch might have been improved. |
| 18285 | All translation loses some content (but language does not create reality) [Carnap] |
| Full Idea: I do not believe in translatability without loss of content, and therefore I think that the content of a world description is influenced to a certain degree by choice of a language form. But that does not mean that reality is created through language. | |
| From: Rudolph Carnap (Letters to Schlick [1935], 1935.12.04), quoted by J. Alberto Coffa - The Semantic Tradition from Kant to Carnap 19 'Truth' | |
| A reaction: It is a mistake to think Quine was the first to spot the interest of translation in philosophy of language. 'Does translation always lose content?' is a very nice question for focusing the problem. |
| 22858 | There is collective action, where a trend is manifest, but is not attributable to individuals [Lukes] |
| Full Idea: There is a phenomenon of collective action, where the policy or action of a collectivity is manifest, but not attributable to particular individuals' decisions or behaviour. | |
| From: Steven Lukes (Power: a Radical View (2nd ed) [2005], 1.4) | |
| A reaction: This observation of Lukes is seen as important in the understanding of social power, but it is also significant for the understanding of the theory of action. Small racial slights by individuals can indicate institutional racism. |
| 22850 | Hidden powers are the most effective [Lukes] |
| Full Idea: Power is at its most effective when it is least observable. | |
| From: Steven Lukes (Power: a Radical View (2nd ed) [2005], Intro) | |
| A reaction: Kind of common sense, though his account has been very influential. We must be cautious about asserting the existence of powers which are massive but totally undetectable. |
| 22854 | Power is a capacity, which may never need to be exercised [Lukes] |
| Full Idea: Power is a capacity not the exercise of that capacity (it may never be, and never need to be, exercised); and you can be powerful by satisfying and advancing others' interests. | |
| From: Steven Lukes (Power: a Radical View (2nd ed) [2005], Intro) | |
| A reaction: A school teacher could, in extremis, bring in the army to control a wildly anarchic class of kids. You control kids by making them want to do what you want them to do. |
| 22852 | The pluralist view says that power is restrained by group rivalry [Lukes] |
| Full Idea: In the 1950s 'pluralism' was a common idea about power - that the concentration of power in America is not excessive because one group always balances the power of others. | |
| From: Steven Lukes (Power: a Radical View (2nd ed) [2005], Intro) | |
| A reaction: [He cites Alan Wolfe's 2000 intro to C. Wright Mills] There must be something to this idea. In the UK we encourage the existence of an official opposition to the government for that reason. |
| 22855 | One-dimensionsal power is behaviour in observable conflicts of interests [Lukes] |
| Full Idea: The one-dimensional view of power involves a focus on behaviour in the making of decisions on issues over which there is an observable conflict of (subjective) interests, revealed by political participation. | |
| From: Steven Lukes (Power: a Radical View (2nd ed) [2005], 1.2) | |
| A reaction: It seems unbalanced to give this the pejorative label 'one-dimensional', as if it wasn't really power at all. Watching police beating demonstrators looks like real power to me. His point that power runs deeper is, of course, a good one. |
| 22856 | Political organisation brings some conflicts to the fore, and suppresses others [Lukes] |
| Full Idea: All forms of political organisation have a bias in favour of the exploitation of some kinds of conflict and the suppression of others, because organisation is the mobilisation of bias. Some issues are organised into politics while others are organised out | |
| From: Steven Lukes (Power: a Radical View (2nd ed) [2005], 1.3) | |
| A reaction: [He cites Schattschneider 1960] This is what Lukes calls the two-dimensional theory of power. The point is that students of power should observe what does not happen, as well as what does. |
| 22857 | The two-dimensional view of power recognises the importance of controlling the agenda [Lukes] |
| Full Idea: The two-dimensional view of power is a major advance over the one-dimensional view. It incorporates the question of the control of the agenda in politics. | |
| From: Steven Lukes (Power: a Radical View (2nd ed) [2005], 1.4) | |
| A reaction: So One-D is controlling what happens in conflicts, and Two-D is controlling the nature of the conflicts. If we keep digging we may come to the power which no one knows exists. |
| 22859 | Power can be exercised to determine a person's desires [Lukes] |
| Full Idea: A may exercise power over B by getting him to do what he does not want to do, but also by influencing, shaping or determining his very wants. | |
| From: Steven Lukes (Power: a Radical View (2nd ed) [2005], 1.4) | |
| A reaction: The classic modern instances of this are advertising and control of the media. This was apparently a new idea from Lukes, but it seems fairly obvious now. This is his third dimension of power. |
| 22863 | Power is the capacity of a social class to realise its interests [Lukes] |
| Full Idea: Poulantzas (1968) defined his concept of power as the capacity of a social class to realise its specific objective interests. | |
| From: Steven Lukes (Power: a Radical View (2nd ed) [2005], 1.8) | |
| A reaction: Lukes offers this as an account of power in terms of structures, rather than of the actions of individuals. Lukes says that power must include the ability of the agent to act differently. Power must involve responsibility. Power is not fate. |
| 22860 | The evidence for the exertion of power need not involve a grievance of the powerless [Lukes] |
| Full Idea: It is inadequate to insist that nondecision-making power only exists where there are grievances which are denied entry into the political process in the form of issues. | |
| From: Steven Lukes (Power: a Radical View (2nd ed) [2005], 1.4) | |
| A reaction: A simple example would be where they tricked you into thinking you couldn't vote in an election, or where the women didn't realise the men were paid more. Part of his third dimension of power. |
| 22861 | Power is affecting a person in a way contrary to their interests [Lukes] |
| Full Idea: I have defined the concept of power by saying that A exercises power over B when A affects B in a manner contrary to B's interests | |
| From: Steven Lukes (Power: a Radical View (2nd ed) [2005], 1.6) | |
| A reaction: I assume he is not referring to when I accidentally spill your beer. His point is, I think, that neither A nor B may be fully, or even partly, aware of what is going on. Presumably A can also exert power over B which is in B's interests. Dentists. |
| 21133 | Supreme power is getting people to have thoughts and desires chosen by you [Lukes] |
| Full Idea: Is it not the supreme exercise of power to get another or others to have the desires you want them to have - that is, to secure their compliance by controlling their thoughts and desires? | |
| From: Steven Lukes (Power: a Radical View (2nd ed) [2005], p.27), quoted by Andrew Shorten - Contemporary Political Theory 06 | |
| A reaction: This seems to be beyond dispute. When the operation is successful, those under your power not only do not need to be intimidated, but they don't even need to be guided. But if two people are in perfect harmony, which one has the power? |
| 22851 | In the 1950s they said ideology is finished, and expertise takes over [Lukes] |
| Full Idea: In the 1950s there was talk of the 'end of ideology' - that grand passions over ideas were exhausted, and in future problems would be solved by technical expertise. | |
| From: Steven Lukes (Power: a Radical View (2nd ed) [2005], Intro) | |
| A reaction: An understandable thought, once fascism and communism seemed to have burned themselves out. Political commentators always try to grip the crowds with simplistic labels, but fewer people will now read up an ideology. Tacit ideology. |
| 22862 | Liberals take people as they are, and take their preferences to be their interests [Lukes] |
| Full Idea: Liberals take people as they are, and relates their interests to what they actually want or prefer. | |
| From: Steven Lukes (Power: a Radical View (2nd ed) [2005], 1.6) | |
| A reaction: He contrasts this with 'reformists' and 'radicals'. I don't see why liberals should be so uncritical of people's desires. Liberals aren't going to implement harmful policies, simply because people want them. He treats liberals as one-dimensional. |
| 22853 | Anyone who thinks capitalism can improve their lives is endorsing capitalism [Lukes] |
| Full Idea: Wage earners consent to capitalist organisation of society when they act as if they could improve their material conditions within the confines of capitalism. | |
| From: Steven Lukes (Power: a Radical View (2nd ed) [2005], Intro) | |
| A reaction: [He is citing Przeworski 1985] Not plausible as it stands. Does a prisoner who tries to improve their life within a hideous prison thereby endorse the prison system? In Auschwitz? Slaves can go along with the system for years, then suddenly rebel. |
