| 20109 | Hegel inserted society and history between the God-world, man-nature, man-being binary pairs [Hegel, by Safranski] |
| Full Idea: Before Hegel, people thought in binary oppositions of God and the world, man and nature, man and being. After Hegel an intervening world of society and history was inserted between these pairs. | |
| From: report of Georg W.F.Hegel (Introduction to the Philosophy of History [1840]) by Rüdiger Safranski - Nietzsche: a philosophical biography 05 | |
| A reaction: This is what Popper later called 'World Three'. This might be seen as the start of what we islanders call 'continental' philosophy, which we have largely ignored. Analytic philosophy only discovered this through philosophy of language. |
| 9766 | Study vagueness first by its logic, then by its truth-conditions, and then its metaphysics [Fine,K] |
| Full Idea: My investigation of vagueness began with the question 'What is the correct logic of vagueness?', which led to the further question 'What are the correct truth-conditions for a vague language?', which led to questions of meaning and existence. | |
| From: Kit Fine (Vagueness, Truth and Logic [1975], Intro) | |
| A reaction: This is the most perfect embodiment of the strategy of analytical philosophy which I have ever read. It is the strategy invented by Frege in the 'Grundlagen'. Is this still the way to go, or has this pathway slowly sunk into the swamp? |
| 9775 | Excluded Middle, and classical logic, may fail for vague predicates [Fine,K] |
| Full Idea: Maybe classical logic fails for vagueness in Excluded Middle. If 'H bald ∨ ¬(H bald)' is true, then one disjunct is true. But if the second is true the first is false, and the sentence is either true or false, contrary to the borderline assumption. | |
| From: Kit Fine (Vagueness, Truth and Logic [1975], 4) | |
| A reaction: Fine goes on to argue against the implication that we need a special logic for vague predicates. |
| 9771 | Logic holding between indefinite sentences is the core of all language [Fine,K] |
| Full Idea: If language is like a tree, then penumbral connection (logic holding among indefinite sentences) is the seed from which the tree grows, for it provides an initial repository of truths that are to be retained throughout all growth. | |
| From: Kit Fine (Vagueness, Truth and Logic [1975], 2) | |
| A reaction: A nice incidental insight arising from his investigation of vagueness. People accept one another's reasons even when they are confused, or hopeless at expressing themselves. Nice. |
| 9768 | Vagueness is semantic, a deficiency of meaning [Fine,K] |
| Full Idea: I take vagueness to be a semantic feature, a deficiency of meaning. It is to be distinguished from generality, undecidability, and ambiguity. | |
| From: Kit Fine (Vagueness, Truth and Logic [1975], Intro) | |
| A reaction: Sounds good. If we cut nature at the joints with our language, then nature is going to be too subtle and vast for our finite and gerrymandered language, and so it will break down in tricky situations. But maybe epistemology precedes semantics? |
| 9776 | A thing might be vaguely vague, giving us higher-order vagueness [Fine,K] |
| Full Idea: There is a possibility of 'higher-order vagueness'. The vague may be vague, or vaguely vague, and so on. If J has few hairs on his head than H, then he may be a borderline case of a borderline case. | |
| From: Kit Fine (Vagueness, Truth and Logic [1975], 5) | |
| A reaction: Such slim grey areas can also be characterised as those where you think he is definitely bald, but I am not so sure. |
| 9767 | A vague sentence is only true for all ways of making it completely precise [Fine,K] |
| Full Idea: A vague sentence is (roughly stated) true if and only if it is true for all ways of making it completely precise (the 'super-truth theory'). | |
| From: Kit Fine (Vagueness, Truth and Logic [1975], Intro) | |
| A reaction: Intuitively this sounds quite promising. Personally I think we should focus on the 'proposition' rather than the 'sentence' (where fifteen sentences might be needed before we can agree on the one proposition). |
| 9770 | Logical connectives cease to be truth-functional if vagueness is treated with three values [Fine,K] |
| Full Idea: With a three-value approach, if P is 'blob is pink' and R is 'blob is red', then P&P is indefinite, but P&R is false, and P∨P is indefinite, but P∨R is true. This means the connectives & and ∨ are not truth-functional. | |
| From: Kit Fine (Vagueness, Truth and Logic [1975], 1) | |
| A reaction: The point is that there could then be no logic in any way classical for vague sentences and three truth values. A powerful point. |
| 9772 | Meaning is both actual (determining instances) and potential (possibility of greater precision) [Fine,K] |
| Full Idea: The meaning of an expression is the product of both its actual meaning (what helps determine its instances and counter-instances), and its potential meaning (the possibilities for making it more precise). | |
| From: Kit Fine (Vagueness, Truth and Logic [1975], 2) | |
| A reaction: A modal approach to meaning is gloriously original. Being quite a fan of real modalities (the possibilities latent in actuality), I find this intuitively appealing. |
| 9773 | With the super-truth approach, the classical connectives continue to work [Fine,K] |
| Full Idea: With the super-truth approach, if P is 'blob is pink' and R is 'blob is red', then P&R is false, and P∨R is true, since one of P and R is true and one is false in any complete and admissible specification. It encompasses all 'penumbral truths'. | |
| From: Kit Fine (Vagueness, Truth and Logic [1975], 3) | |
| A reaction: [See Idea 9767 for the super-truth approach, and Idea 9770 for a contrasting view] The approach, which seems quite appealing, is that we will in no circumstances give up basic classical logic, but we will make maximum concessions to vagueness. |
| 9774 | Borderline cases must be under our control, as capable of greater precision [Fine,K] |
| Full Idea: Any borderline case must be under our control, in the sense that it can be settled by making the predicates more precise. | |
| From: Kit Fine (Vagueness, Truth and Logic [1975], 3) | |
| A reaction: Sounds good. Consider an abstract concept like the equator. It is precise on a map of the world, but vague when you are in the middle of the tropics. But we can always form a committee to draw a (widish) line on the ground delineating it. |
| 9769 | Vagueness can be in predicates, names or quantifiers [Fine,K] |
| Full Idea: There are three possible sources of vagueness: the predicates, the names, and the quantifiers. | |
| From: Kit Fine (Vagueness, Truth and Logic [1975], 1) | |
| A reaction: Presumably a vagueness about the domain of discussion would be a vagueness in the quantifier. This is a helpful preliminary division, in the semantic approach to vagueness. |
| 468 | Musical performance can reveal a range of virtues [Damon of Ath.] |
| Full Idea: In singing and playing the lyre, a boy will be likely to reveal not only courage and moderation, but also justice. | |
| From: Damon (fragments/reports [c.460 BCE], B4), quoted by (who?) - where? |
| 23274 | World history has no room for happiness [Hegel] |
| Full Idea: World history is not the place for happiness. Periods of happiness are empty pages in history. | |
| From: Georg W.F.Hegel (Introduction to the Philosophy of History [1840], 3) | |
| A reaction: Clearly, Hegel thinks the progress of world history is much more important than happiness. This idea gives backing to those who don't care much about the casualties on either side in a major war. |
| 23275 | The state of nature is one of untamed brutality [Hegel] |
| Full Idea: The 'state of nature' is not an ideal condition, but a condition of injustice, of violence, of untamed natural drives, inhuman acts and emotions. | |
| From: Georg W.F.Hegel (Introduction to the Philosophy of History [1840], 3) | |
| A reaction: He agrees with Hobbes, and disagrees with Rousseau. Hobbes's solution is authoritarian monarchy, but Hegel's solution is the unified and focused state, in which freedom can be realised. |
| 23276 | The soul of the people is an organisation of its members which produces an essential unity [Hegel] |
| Full Idea: The soul [of the people] exists only insofar as it is an organisation of its members, which - by taking itself together in its simple unity - produce the soul. Thus the people is one individuality in its essence. | |
| From: Georg W.F.Hegel (Introduction to the Philosophy of History [1840], 3) | |
| A reaction: Hegel is seen (e.g. by Charles Taylor) as the ancestor of a rather attractive communitarianism, but I think Popper is more accurate in seeing him as the first stage of modern totalitarianism. The people seen as one individual terrifies me. |
| 23272 | The human race matters, and individuals have little importance [Hegel] |
| Full Idea: Individuals are of slight importance compared to the mass of the human race. | |
| From: Georg W.F.Hegel (Introduction to the Philosophy of History [1840], 3) | |
| A reaction: A perfect statement of the anti-liberal viewpoint. Hegel is complex, but this is the strand that leads to ridiculous totalitarianism, where the highest ideal is to die for the glory of your nation. Importance can only start from individuals. |
| 23273 | In a good state the goal of the citizens and of the whole state are united [Hegel] |
| Full Idea: A state is well constituted and internally strong if the private interest of the citizens is united in the universal goal of the state. | |
| From: Georg W.F.Hegel (Introduction to the Philosophy of History [1840], 3) | |
| A reaction: The obvious question is who decides on the goals, and what to do with the citizens who don't accept them. |
| 23271 | The goal of the world is Spirit's consciousness and enactment of freedom [Hegel] |
| Full Idea: The final goal of the world is Spirit's consciousness of its freedom, and hence also the actualisation of that very freedom. | |
| From: Georg W.F.Hegel (Introduction to the Philosophy of History [1840], 3) | |
| A reaction: I have the impression that this ridiculous idea has been very influential in modern French philosophy, since they all seem to be dreaming of some perfect freedom at the end of the rainbow. Freedom is good, but this gives it a bad name. |
| 23270 | We should all agree that there is reason in history [Hegel] |
| Full Idea: We ought to have the firm and unconquerable belief that there is reason in history. | |
| From: Georg W.F.Hegel (Introduction to the Philosophy of History [1840], 2) | |
| A reaction: This is a ridiculous but hugely influential idea, and I have no idea what makes Hegel believe it. It is the Stoic idea that nature is intrinsically rational, but extending it to human history is absurd. Human exceptionalism. Needs a dose of Darwin. |
