8927 | Philosophy moves essentially in the element of universality [Hegel] |
Full Idea: Philosophy moves essentially in the element of universality. | |
From: Georg W.F.Hegel (Phenomenology of Spirit [1807], Pref 01) | |
A reaction: I would take this to be uncontroversially correct. An interesting test case is applied ethics, which seems embedded in current cultural practices. I would always take it to be searching for what is universal in each situation. |
21776 | Philosophy aims to reveal the necessity and rationality of the categories of nature and spirit [Hegel, by Houlgate] |
Full Idea: For Hegel, philosophy's principal task is to disclose the enduring necessity and rationality of the categories and forms of nature and spirit that it examines. | |
From: report of Georg W.F.Hegel (Phenomenology of Spirit [1807]) by Stephen Houlgate - An Introduction to Hegel 4 'Phenomenology' | |
A reaction: The idea that a miserable little evolved and transient mammal on a tiny planet has direct insight into the necessities and categories of nature and spirit looks a shade optimistic to me. You have to admire the ambition, though. |
8935 | Without philosophy, science is barren and futile [Hegel] |
Full Idea: Let other sciences try to argue as much as they like without philosophy - without it they can have in them neither life, Spirit, nor truth. | |
From: Georg W.F.Hegel (Phenomenology of Spirit [1807], Pref 67) | |
A reaction: To be pinned up in every physics laboratory in the world. On the whole I agree with this. My slogan is 'science is the servant of philosophy'. An unphilosophical scientist is just a technologist, an artisan. |
22082 | Truth does not appear by asserting reasons and then counter-reasons [Hegel] |
Full Idea: It is not difficult to see that the way of asserting a proposition, adducing reasons for it, and in the same way refuting its opposite by reasons, is not the form in which truth can appear. | |
From: Georg W.F.Hegel (Phenomenology of Spirit [1807], p.28), quoted by Stephen Houlgate - Hegel p.100 | |
A reaction: This is a pretty good description of the way Plato and Aristotle do philosophy, so this idea, which must be a founding idea for the 'continental school', is extremely radical. Personally I identify rationality with believing things for good reasons. |
22035 | The structure of reason is a social and historical achievement [Hegel, by Pinkard] |
Full Idea: The lesson of Hegel's Phenomenology was that the structure of reason was social, and was therefore a historical achievement. | |
From: report of Georg W.F.Hegel (Phenomenology of Spirit [1807]) by Terry Pinkard - German Philosophy 1760-1860 10 | |
A reaction: This must be one of the most influential ideas to have filtered into the modern world. It is a predecessor of Marxist sociology. The idea that stands against it is Frege's platonist view of logic, making it necessary, despite being historical. |
8932 | Truth does not come from giving reasons for and against propositions [Hegel] |
Full Idea: The way of asserting a proposition, adducing reasons for it, and in the same way refuting its opposite by reasons, is not the form in which truth can appear. | |
From: Georg W.F.Hegel (Phenomenology of Spirit [1807], Pref 48) | |
A reaction: I can't see Plato or Aristotle agreeing with this. It is obviously the prelude to Hegel's dialectical account of reasoning. However, if we don't believe things because we have good reason to, I'm not sure where we shoud start. |
9376 | A sentence may simultaneously define a term, and also assert a fact [Boghossian] |
Full Idea: It doesn't follow from the fact that a given sentence is being used to implicitly define one of its ingredient terms, that it is not a factual statement. 'This stick is a meter long at t' may define an ingredient terms and express something factual. | |
From: Paul Boghossian (Analyticity Reconsidered [1996], §III) | |
A reaction: This looks like a rather good point, but it is tied in with a difficulty about definition, which is deciding which sentences are using a term, and which ones are defining it. If I say 'this stick in Paris is a meter long', I'm not defining it. |
13252 | Some truths have true negations [Beall/Restall] |
Full Idea: Dialetheism is the view that some truths have true negations. | |
From: JC Beall / G Restall (Logical Pluralism [2006], 7.4) | |
A reaction: The important thing to remember is that they are truths. Thus 'Are you feeling happy?' might be answered 'Yes and no'. |
13247 | A truthmaker is an object which entails a sentence [Beall/Restall] |
Full Idea: The truthmaker thesis is that an object is a truthmaker for a sentence if and only if its existence entails the sentence. | |
From: JC Beall / G Restall (Logical Pluralism [2006], 5.5.3) | |
A reaction: The use of the word 'object' here is even odder than usual, and invites many questions. And the 'only if' seems peculiar, since all sorts of things can make a sentence true. 'There is someone in the house' for example. |
7077 | The true is the whole [Hegel] |
Full Idea: The true is the whole. | |
From: Georg W.F.Hegel (Phenomenology of Spirit [1807], Pref 20) | |
A reaction: This is the full idealist coherence view of truth, that one only approaches the Truth (capital T) as one builds up a more and more coherent picture. It makes truth unattainable, and that strikes me as a bit silly. |
13249 | (∀x)(A v B) |- (∀x)A v (∃x)B) is valid in classical logic but invalid intuitionistically [Beall/Restall] |
Full Idea: The inference of 'distribution' (∀x)(A v B) |- (∀x)A v (∃x)B) is valid in classical logic but invalid intuitionistically. It is straightforward to construct a 'stage' at which the LHS is true but the RHS is not. | |
From: JC Beall / G Restall (Logical Pluralism [2006], 6.1.2) | |
A reaction: This seems to parallel the iterative notion in set theory, that you must construct your hierarchy. All part of the general 'constructivist' approach to things. Is some kind of mad platonism the only alternative? |
13243 | Excluded middle must be true for some situation, not for all situations [Beall/Restall] |
Full Idea: Relevant logic endorses excluded middle, ..but says instances of the law may fail. Bv¬B is true in every situation that settles the matter of B. It is necessary that there is some such situation. | |
From: JC Beall / G Restall (Logical Pluralism [2006], 5.2) | |
A reaction: See next idea for the unusual view of necessity on which this rests. It seems easier to assert something about all situations than just about 'some' situation. |
13242 | It's 'relevantly' valid if all those situations make it true [Beall/Restall] |
Full Idea: The argument from P to A is 'relevantly' valid if and only if, for every situation in which each premise in P is true, so is A. | |
From: JC Beall / G Restall (Logical Pluralism [2006], 5.2) | |
A reaction: I like the idea that proper inference should have an element of relevance to it. A falsehood may allow all sorts of things, without actually implying them. 'Situations' sound promising here. |
13245 | Relevant consequence says invalidity is the conclusion not being 'in' the premises [Beall/Restall] |
Full Idea: Relevant consequence says the conclusion of a relevantly invalid argument is not 'carried in' the premises - it does not follow from the premises. | |
From: JC Beall / G Restall (Logical Pluralism [2006], 5.3.3) | |
A reaction: I find this appealing. It need not invalidate classical logic. It is just a tougher criterion which is introduced when you want to do 'proper' reasoning, instead of just playing games with formal systems. |
13246 | Relevant logic does not abandon classical logic [Beall/Restall] |
Full Idea: We have not abandoned classical logic in our acceptance of relevant logic. | |
From: JC Beall / G Restall (Logical Pluralism [2006], 5.4) | |
A reaction: It appears that classical logic is straightforwardly accepted, but there is a difference of opinion over when it is applicable. |
13254 | A doesn't imply A - that would be circular [Beall/Restall] |
Full Idea: We could reject the inference from A to itself (on grounds of circularity). | |
From: JC Beall / G Restall (Logical Pluralism [2006], 8) | |
A reaction: [Martin-Meyer System] 'It's raining today'. 'Are you implying that it is raining today?' 'No, I'm SAYING it's raining today'. Logicians don't seem to understand the word 'implication'. Logic should capture how we reason. Nice proposal. |
13255 | Relevant logic may reject transitivity [Beall/Restall] |
Full Idea: Some relevant logics reject transitivity, but we defend the classical view. | |
From: JC Beall / G Restall (Logical Pluralism [2006], 8) | |
A reaction: [they cite Neil Tennant for this view] To reject transitivity (A?B ? B?C ? A?C) certainly seems a long way from classical logic. But in everyday inference Tennant's idea seems good. The first premise may be irrelevant to the final conclusion. |
13250 | Free logic terms aren't existential; classical is non-empty, with referring names [Beall/Restall] |
Full Idea: A logic is 'free' to the degree it refrains from existential import of its singular and general terms. Classical logic must have non-empty domain, and each name must denote in the domain. | |
From: JC Beall / G Restall (Logical Pluralism [2006], 7.1) | |
A reaction: My intuition is that logic should have no ontology at all, so I like the sound of 'free' logic. We can't say 'Pegasus does not exist', and then reason about Pegasus just like any other horse. |
13235 | Logic studies consequence; logical truths are consequences of everything, or nothing [Beall/Restall] |
Full Idea: Nowadays we think of the consequence relation itself as the primary subject of logic, and view logical truths as degenerate instances of this relation. Logical truths follow from any set of assumptions, or from no assumptions at all. | |
From: JC Beall / G Restall (Logical Pluralism [2006], 2.2) | |
A reaction: This seems exactly right; the alternative is the study of necessities, but that may not involve logic. |
13238 | Syllogisms are only logic when they use variables, and not concrete terms [Beall/Restall] |
Full Idea: According to the Peripatetics (Aristotelians), only syllogistic laws stated in variables belong to logic, and not their applications to concrete terms. | |
From: JC Beall / G Restall (Logical Pluralism [2006], 2.5) | |
A reaction: [from Lukasiewicz] Seems wrong. I take it there are logical relations between concrete things, and the variables are merely used to describe these relations. Variables lack the internal powers to drive logical necessities. Variables lack essence! |
13234 | The view of logic as knowing a body of truths looks out-of-date [Beall/Restall] |
Full Idea: Through much of the 20th century the conception of logic was inherited from Frege and Russell, as knowledge of a body of logical truths, as arithmetic or geometry was a knowledge of truths. This is odd, and a historical anomaly. | |
From: JC Beall / G Restall (Logical Pluralism [2006], 2.2) | |
A reaction: Interesting. I have always taken this idea to be false. I presume logic has minimal subject matter and truths, and preferably none at all. |
13232 | Logic studies arguments, not formal languages; this involves interpretations [Beall/Restall] |
Full Idea: Logic does not study formal languages for their own sake, which is formal grammar. Logic evaluates arguments, and primarily considers formal languages as interpreted. | |
From: JC Beall / G Restall (Logical Pluralism [2006], 2.1) | |
A reaction: Hodges seems to think logic just studies formal languages. The current idea strikes me as a much more sensible view. |
13241 | The model theory of classical predicate logic is mathematics [Beall/Restall] |
Full Idea: The model theory of classical predicate logic is mathematics if anything is. | |
From: JC Beall / G Restall (Logical Pluralism [2006], 4.2.1) | |
A reaction: This is an interesting contrast to the claim of logicism, that mathematics reduces to logic. This idea explains why students of logic are surprised to find themselves involved in mathematics. |
13253 | There are several different consequence relations [Beall/Restall] |
Full Idea: We are pluralists about logical consequence because we take there to be a number of different consequence relations, each reflecting different precisifications of the pre-theoretic notion of deductive logical consequence. | |
From: JC Beall / G Restall (Logical Pluralism [2006], 8) | |
A reaction: I don't see how you avoid the slippery slope that leads to daft logical rules like Prior's 'tonk' (from which you can infer anything you like). I say that nature imposes logical conquence on us - but don't ask me to prove it. |
13240 | A sentence follows from others if they always model it [Beall/Restall] |
Full Idea: The sentence X follows logically from the sentences of the class K if and only if every model of the class K is also a model of the sentence X. | |
From: JC Beall / G Restall (Logical Pluralism [2006], 3.2) | |
A reaction: This why the symbol |= is often referred to as 'models'. |
9375 | Conventionalism agrees with realists that logic has truth values, but not over the source [Boghossian] |
Full Idea: Conventualism is a factualist view: it presupposes that sentences of logic have truth values. It differs from a realist view in its conception of the source of those truth values, not on their existence. I call the denial of truths Non-Factualism. | |
From: Paul Boghossian (Analyticity Reconsidered [1996], §III) | |
A reaction: It barely seems to count as truth is we say 'p is true because we say so'. It is a truth about an agreement, not a truth about logic. Driving on the left isn't a truth about which side of the road is best. |
13236 | Logical truth is much more important if mathematics rests on it, as logicism claims [Beall/Restall] |
Full Idea: If mathematical truth reduces to logical truth then it is important what counts as logically true, …but if logicism is not a going concern, then the body of purely logical truths will be less interesting. | |
From: JC Beall / G Restall (Logical Pluralism [2006], 2.2) | |
A reaction: Logicism would only be one motivation for pursuing logical truths. Maybe my new 'Necessitism' will derive the Peano Axioms from broad necessary truths, rather than from logic. |
13237 | Preface Paradox affirms and denies the conjunction of propositions in the book [Beall/Restall] |
Full Idea: The Paradox of the Preface is an apology, that you are committed to each proposition in the book, but admit that collectively they probably contain a mistake. There is a contradiction, of affirming and denying the conjunction of propositions. | |
From: JC Beall / G Restall (Logical Pluralism [2006], 2.4) | |
A reaction: This seems similar to the Lottery Paradox - its inverse perhaps. Affirm all and then deny one, or deny all and then affirm one? |
13244 | Relevant necessity is always true for some situation (not all situations) [Beall/Restall] |
Full Idea: In relevant logic, the necessary truths are not those which are true in every situation; rather, they are those for which it is necessary that there is a situation making them true. | |
From: JC Beall / G Restall (Logical Pluralism [2006], 5.2) | |
A reaction: This seems to rest on the truthmaker view of such things, which I find quite attractive (despite Merricks's assault). Always ask what is making some truth necessary. This leads you to essences. |
15611 | I develop philosophical science from the simplest appearance of immediate consciousness [Hegel, by Hegel] |
Full Idea: In my 'Phenomenology of Spirit' the procedure adopted was to begin from the first and simplest appearance of the spirit, from immediate consciousness, and to develop the dialectic right up to the standpoint of philosophical science. | |
From: report of Georg W.F.Hegel (Phenomenology of Spirit [1807]) by Georg W.F.Hegel - Logic (Encyclopedia I) §25 Rem | |
A reaction: I take metaphysics to be either Parmenidean (starting from Being) or Cartesian (starting from mind), and this (surprisingly, given his lengthy talk of Being) shows Hegel to be a quintessentially Cartesian philosopher. Aristotle is the great Parmenidean. |
8934 | Being is Thought [Hegel] |
Full Idea: Being is Thought. | |
From: Georg W.F.Hegel (Phenomenology of Spirit [1807], Pref 54) | |
A reaction: You won't find a more succinct slogan for idealism than that. Speaking as what Tim Williamson (referring to himself) calls a 'rottweiler realist', I can't quite get the hang of Hegel's claim. What does he think thought is, if it isn't about the world? |
8928 | The Absolute is not supposed to be comprehended, but felt and intuited [Hegel] |
Full Idea: The Absolute is not supposed to be comprehended, it is to be felt and intuited. | |
From: Georg W.F.Hegel (Phenomenology of Spirit [1807], Pref 06) | |
A reaction: Hegel was a rather romantic philosopher. Where does the 'supposed' come from? If the Absolute is only felt and intuited, can the resulting apprehensions be reported to others? Is this, in fact, mysticism? |
21774 | Genuine idealism is seeing the ideal structure of the world [Hegel, by Houlgate] |
Full Idea: Genuine (as opposed to subjective) idealism, for Hegel, is the point of view that knows the world to have a rational, and therefore 'ideal', structure. | |
From: report of Georg W.F.Hegel (Phenomenology of Spirit [1807]) by Stephen Houlgate - An Introduction to Hegel 04 'The Unhappy' | |
A reaction: Compare Leibniz, whose monad theory is said to be a sort of idealism, because it places ideas at the heart of reality. Is Plato also this sort of 'genuine' idealism? Do we need different terms for 'genuine' and 'subjective' idealism? And 'transcendental'? |
8929 | In the Absolute everything is the same [Hegel] |
Full Idea: In the Absolute everything is the same. | |
From: Georg W.F.Hegel (Phenomenology of Spirit [1807], Pref 16) | |
A reaction: This is indistinguishable from the great spherical reality of Parmenides. It is not unreasonable to enquire about the epistemology of this claim. Is Hegel a seer, or can we all intuit this insight into reality? |
9369 | 'Snow is white or it isn't' is just true, not made true by stipulation [Boghossian] |
Full Idea: Isn't it overwhelmingly obvious that 'Either snow is white or it isn't' was true before anyone stipulated a meaning for it, and that it would have been true even if no one had thought about it, or chosen it to be expressed by one of our sentences? | |
From: Paul Boghossian (Analyticity Reconsidered [1996], §I) | |
A reaction: Boghossian would have to believe in propositions (unexpressed truths) to hold this - which he does. I take the notion of truth to only have relevance when there are minds around. Otherwise the so-called 'truths' are just the facts. |
9367 | The a priori is explained as analytic to avoid a dubious faculty of intuition [Boghossian] |
Full Idea: The central impetus behind the analytic explanation of the a priori is a desire to explain the possibility of a priori knowledge without having to postulate a special evidence-gathering faculty of intuition. | |
From: Paul Boghossian (Analyticity Reconsidered [1996], §I) | |
A reaction: I don't see at all why one has to postulate a 'faculty' in order to talk about intuition. I take an intuition to be an apprehension of a probable truth, combined with an inability to articulate how the conclusion was arrived at. |
9373 | That logic is a priori because it is analytic resulted from explaining the meaning of logical constants [Boghossian] |
Full Idea: The analytic theory of the apriority of logic arose indirectly, as a by-product of the attempt to explain in what a grasp of the meaning of the logical constants consists. | |
From: Paul Boghossian (Analyticity Reconsidered [1996], §III) | |
A reaction: Preumably he is referring to Wittgenstein's anguish over the meaning of the word 'not' in his World War I notebooks. He first defined the constants by truth tables, then asserted that they were purely conventional - so logic is conventional. |
9380 | We can't hold a sentence true without evidence if we can't agree which sentence is definitive of it [Boghossian] |
Full Idea: If there is no sentence I must hold true if it is to mean what it does, then there is no basis on which to argue that I am entitled to hold it true without evidence. | |
From: Paul Boghossian (Analyticity Reconsidered [1996], §III) | |
A reaction: He is exploring Quine's view. Truth by convention depends on agreeing which part of the usage of a term constitutes its defining sentence(s), and that may be rather tricky. Boghossian says this slides into the 'dreaded indeterminacy of meaning'. |
9384 | We may have strong a priori beliefs which we pragmatically drop from our best theory [Boghossian] |
Full Idea: It is consistent with a belief's being a priori in the strong sense that we should have pragmatic reasons for dropping it from our best overall theory. | |
From: Paul Boghossian (Analyticity Reconsidered [1996], n 6) | |
A reaction: Does 'dropping it' from the theory mean just ignoring it, or actually denying it? C.I. Lewis is the ancestor of this view. Could it be our 'best' theory, while conflicting with beliefs that were strongly a priori? Pragmatism can embrace falsehoods. |
21773 | Experience is immediacy, unity, forces, self-awareness, reason, culture, absolute being [Hegel, by Houlgate] |
Full Idea: Experience moves from 1) immediacy, to 2) united objects with properties, 3) its forces and laws, 4) self-consciousness in the process, 5) seeing a rational realm, 6) seeing a cultural realm, 7) seeing the absolute being of consciousness. | |
From: report of Georg W.F.Hegel (Phenomenology of Spirit [1807]) by Stephen Houlgate - An Introduction to Hegel 03 'From certainty' | |
A reaction: [My summary of Houlgate's summary of the key sequence of ideas in The Phenomenology of Spirit]. I stare at it with bewilderment, but cannot decide whether or not Hegel is pursuing a worthwhile project. [also Houlgate p.77 and 102] |
22033 | Hegel tried to avoid Kant's dualism of neutral intuitions and imposed concepts [Hegel, by Pinkard] |
Full Idea: Hegel tried to avoid the untenable Kantian dualism between concepts and intuitions, and the Kantian mechanism of the 'imposition' of concepts on sensibility entailed by that dualism (with intuition having neutral content). | |
From: report of Georg W.F.Hegel (Phenomenology of Spirit [1807]) by Terry Pinkard - German Philosophy 1760-1860 09 | |
A reaction: [Pinker is describing the opening of Phenomenology] In modern discussions this concerns the idea of The Given, which is wholly uninterpreted raw experience. Sellars and MacDowell. Kant seems to split an agent into two (Master/Slave). |
9374 | If we learn geometry by intuition, how could this faculty have misled us for so long? [Boghossian] |
Full Idea: If we learn geometrical truths by intuition, how could this faculty have misled us for so long? | |
From: Paul Boghossian (Analyticity Reconsidered [1996], §III) | |
A reaction: This refers to the development of non-Euclidean geometries, though the main misleading concerns parallels, which involves infinity. Boghossian cites 'distance' as a concept the Euclideans had misunderstood. Why shouldn't intuitions be wrong? |
21771 | Consciousness derives its criterion of knowledge from direct knowledge of its own being [Hegel] |
Full Idea: In what consciousness affirms from within itself as being-in-itself or the True we have the standard which consciousness itself sets up by which to measure what it knows. | |
From: Georg W.F.Hegel (Phenomenology of Spirit [1807], p.053), quoted by Stephen Houlgate - An Introduction to Hegel 03 'The Method' | |
A reaction: This seems to be a very close relation of Descartes' 'clear and distinct conceptions'. This certainly places Hegel in the Rationalist camp. |
20741 | Consciousness is shaped dialectically, by opposing forces and concepts [Hegel, by Aho] |
Full Idea: In 'The Phenomenology of Spirit' Hegel offers a panoptic account of Western consciousness as a dialectical process shaped by opposing principles - such as subject/object, freedom/determinism, temporal/eternal, and particular/universal. | |
From: report of Georg W.F.Hegel (Phenomenology of Spirit [1807]) by Kevin Aho - Existentialism: an introduction 2 'Subjective' | |
A reaction: A helpful pointer, for us poor analytic philosophers, who stare in bewilderment at Hegel's stuff, despite its apparent importance. At moment it is the politics that strikes me as most interesting in Hegel. This is cultured consciousness, pre-Marx. |
21770 | Consciousness is both of objects, and of itself [Hegel] |
Full Idea: Consciousness is, on the one hand, consciousness of the object, and on the other, consciousness of itself. | |
From: Georg W.F.Hegel (Phenomenology of Spirit [1807], p.052), quoted by Stephen Houlgate - An Introduction to Hegel 03 'The Method' | |
A reaction: Hume challenges whether there is any knowledge of consciousness purely in itself. Schopenhauer flatly disagreed (Idea 4166) - but then he would, wouldn't he? |
5647 | Hegel claims knowledge of self presupposes desire, and hence objects [Hegel, by Scruton] |
Full Idea: Hegel seems to argue that the immediate knowledge of self (the Cartesian premise) presupposes the activity that constitutes the self, and this presupposes desire, and hence the knowledge of objects. | |
From: report of Georg W.F.Hegel (Phenomenology of Spirit [1807]) by Roger Scruton - Short History of Modern Philosophy Ch.12 | |
A reaction: This hardly amounts to an argument, but I find it quite sympathetic as a claim. It fits comfortably with modern externalist accounts of thought. While solipsism seems a logical possibility, it hardly amounts to a coherent account of mental life. |
5648 | For Hegel knowledge of self presupposes objects, and also a public and moral social world [Hegel, by Scruton] |
Full Idea: Hegel tries to show that knowledge of self as subject presupposes not just knowledge of objects, but knowledge of a public social world, in which there is moral order and civic trust. | |
From: report of Georg W.F.Hegel (Phenomenology of Spirit [1807]) by Roger Scruton - Short History of Modern Philosophy Ch.12 | |
A reaction: This is not far off Wittgenstein's private language argument. It is also Popper's 'World Three', of society and language. Human reality is incomprehensible without some recognition of the culture in which we immerse, like fish in water. |
13239 | Judgement is always predicating a property of a subject [Beall/Restall] |
Full Idea: All judgement, for Kant, is essentially the predication of some property to some subject. | |
From: JC Beall / G Restall (Logical Pluralism [2006], 2.5) | |
A reaction: Presumably the denial of a predicate could be a judgement, or the affirmation of ambiguous predicates? |
9378 | If meaning depends on conceptual role, what properties are needed to do the job? [Boghossian] |
Full Idea: Conceptual Role Semantics must explain what properties an inference or sentence involving a logical constant must have, if that inference or sentence is to be constitutive of its meaning. | |
From: Paul Boghossian (Analyticity Reconsidered [1996], §III) | |
A reaction: This is my perennial request that if something is to be defined by its function (or role), we must try to explain what properties it has that make its function possible, and those properties will be the more basic explanation. |
9377 | 'Conceptual role semantics' says terms have meaning from sentences and/or inferences [Boghossian] |
Full Idea: 'Conceptual role semantics' says the logical constants mean what they do by virtue of figuring in certain inferences and/or sentences involving them and not others, ..so some inferences and sentences are constitutive of an expression's meaning. | |
From: Paul Boghossian (Analyticity Reconsidered [1996], §III) | |
A reaction: If the meaning of the terms derives from the sentences in which they figure, that seems to be meaning-as-use. The view that it depends on the inferences seems very different, and is a more interesting but more risky claim. |
9372 | Could expressions have meaning, without two expressions possibly meaning the same? [Boghossian] |
Full Idea: Could there be a fact of the matter about what each expression means, but no fact of the matter about whether they mean the same? | |
From: Paul Boghossian (Analyticity Reconsidered [1996], §II) | |
A reaction: He is discussing Quine's attack on synonymy, and his scepticism about meaning. Boghossian and I believe in propositions, so we have no trouble with two statements having the same meaning. Denial of propositions breeds trouble. |
13248 | We can rest truth-conditions on situations, rather than on possible worlds [Beall/Restall] |
Full Idea: Situation semantics is a variation of the truth-conditional approach, taking the salient unit of analysis not to be the possible world, or some complete consistent index, but rather the more modest 'situation'. | |
From: JC Beall / G Restall (Logical Pluralism [2006], 5.5.4) | |
A reaction: When I read Davidson (and implicitly Frege) this is what I always assumed was meant. The idea that worlds are meant has crept in to give truth conditions for modal statements. Hence situation semantics must cover modality. |
13233 | Propositions commit to content, and not to any way of spelling it out [Beall/Restall] |
Full Idea: Our talk of propositions expresses commitment to the general notion of content, without a commitment to any particular way of spelling this out. | |
From: JC Beall / G Restall (Logical Pluralism [2006], 2.1) | |
A reaction: As a fan of propositions I like this. It leaves open the question of whether the content belongs to the mind or the language. Animals entertain propositions, say I. |
17721 | There are no truths in virtue of meaning, but there is knowability in virtue of understanding [Boghossian, by Jenkins] |
Full Idea: Boghossian distinguishes metaphysical analyticity (truth purely in virtue of meaning, debunked by Quine, he says) from epistemic analyticity (knowability purely in virtue of understanding - a notion in good standing). | |
From: report of Paul Boghossian (Analyticity Reconsidered [1996]) by Carrie Jenkins - Grounding Concepts 2.4 | |
A reaction: [compressed] This fits with Jenkins's claim that we have a priori knowledge just through understanding and relating our concepts. She, however, rejects that idea that a priori is analytic. |
9368 | Epistemological analyticity: grasp of meaning is justification; metaphysical: truth depends on meaning [Boghossian] |
Full Idea: The epistemological notion of analyticity: a statement is 'true by virtue of meaning' provided that grasp of its meaning alone suffices for justified belief in its truth; the metaphysical reading is that it owes its truth to its meaning, not to facts. | |
From: Paul Boghossian (Analyticity Reconsidered [1996], §I) | |
A reaction: Kripke thinks it is neither, but is a purely semantic notion. How could grasp of meaning alone be a good justification if it wasn't meaning which was the sole cause of the statement's truth? I'm not convinced by his distinction. |
8930 | The in-itself must become for-itself, which requires self-consciousness [Hegel] |
Full Idea: The in-itself has to express itself outwardly and become for itself, and this means simply that it has to posit self-consciousness as one with itself. | |
From: Georg W.F.Hegel (Phenomenology of Spirit [1807], Pref 26) | |
A reaction: This famous distinction seems to be at the core of idealism, but also to be the germ of existentialism (prior to Kierkegaard), which builds on this view of what it means to exist as an individual. Self-consciousness in nature is inevitable? |
22034 | Modern life needs individuality, but must recognise that human agency is social [Hegel, by Pinkard] |
Full Idea: Hegel argued that the modern world necessarily had to make space for individuals and their inviolable conscience, while not becoming so individualistic that it failed to acknowledge the deep sociality of human agency. ...Subjectivity became a right. | |
From: report of Georg W.F.Hegel (Phenomenology of Spirit [1807]) by Terry Pinkard - German Philosophy 1760-1860 09 | |
A reaction: [at the end of the chapter on the history of Geist in the Phenomenology] Conservatives, revolutionaries and communitarians all claim Hegel as their own. The sociality is a matter of mutual law-giving, as in the Master/Slave. |
8936 | Human nature only really exists in an achieved community of minds [Hegel] |
Full Idea: Human nature only really exists in an achieved community of minds. | |
From: Georg W.F.Hegel (Phenomenology of Spirit [1807], Pref 69) | |
A reaction: A lovely slogan, that makes Hegel the father of the communitarian movement. The politics of Hegel can, of course, be sinister, so one must proceed with care, and study history to see where it can all go wrong. |
21987 | History is the progress of the consciousness of freedom [Hegel] |
Full Idea: The History of the World is none other than than the progress of the consciousness of freedom. | |
From: Georg W.F.Hegel (Phenomenology of Spirit [1807]), quoted by Peter Singer - Marx 2 | |
A reaction: [no ref given] Presumably there is an evolutionary view implicit in this. Presumably also later generations are hereby superior to previous generations. Since no one still has this view of history, does that invalidate Hegel? |
8931 | The movement of pure essences constitutes the nature of scientific method [Hegel] |
Full Idea: The movement of pure essences constitutes the nature of scientific method in general. | |
From: Georg W.F.Hegel (Phenomenology of Spirit [1807], Pref 34) | |
A reaction: This would appear to be precisely the idea of scientific essentialism - if he is saying that science seeks to understand the movement (or power) of essences as they occur in nature. |
8933 | Science confronts the inner necessities of objects [Hegel] |
Full Idea: Scientific cognition demands surrender to the life of the object, or, what amounts to the same thing, confronting and expressing its inner necessity. | |
From: Georg W.F.Hegel (Phenomenology of Spirit [1807], Pref 53) | |
A reaction: This strikes me as being a much better account of what science tries to do than all the modern talk about laws and theories. |
21775 | The God of revealed religion can only be understood through pure speculative knowledge [Hegel] |
Full Idea: God is attainable in pure speculative knowledge alone and is only in that knowledge, and is only that knowledge itself, for He is Spirit; and this speculative knowledge is the knowledge of revealed religion. | |
From: Georg W.F.Hegel (Phenomenology of Spirit [1807], p.461), quoted by Stephen Houlgate - An Introduction to Hegel 04 'Absolute' | |
A reaction: If you were hoping to find out why Hegel believed in God, I fear this is the best evidence available. He is evidently opposed to natural theology. Hegel's language makes it very hard to grasp how we sees the nature of God. |
6917 | God is the essence of thought, abstracted from the thinker [Hegel, by Feuerbach] |
Full Idea: In Hegel the essence of God is actually nothing other than the essence of thought, or thought abstracted from the ego, that is, from the one who thinks. | |
From: report of Georg W.F.Hegel (Phenomenology of Spirit [1807]) by Ludwig Feuerbach - Principles of Philosophy of the Future §23 | |
A reaction: Presumably Descartes' Cogito is the origin for this train of thought. This is Feuerbach's reading of Hegel, but the former was keen on the idea of God as idealised humanity. |
6915 | Hegel made the last attempt to restore Christianity, which philosophy had destroyed [Hegel, by Feuerbach] |
Full Idea: The Hegelian philosophy is the last magnificent attempt to restore Christianity, which was lost and wrecked, through philosophy, and to restore Christianity (as usual in the modern era) by identifying it with the negation of Christianity. | |
From: report of Georg W.F.Hegel (Phenomenology of Spirit [1807]) by Ludwig Feuerbach - Principles of Philosophy of the Future §21 | |
A reaction: What is meant by the 'negation' of Christianity needs some untangling, but I suspect that a lot of 'continental' philosophy 1750-1950 is to do with Christianity, unlike British empiricism, which is intrinsically atheistic. |
