23548 | Indeterminacy is in conflict with classical logic [Fine,K] |
Full Idea: I now believe that the existence of indeterminacy is in conflict with classical logic. | |
From: Kit Fine (Vagueness: a global approach [2020], 3) | |
A reaction: I think that prior to this Fine had defended classical logic. Presumably the difficulty is over Bivalence. Nietzsche spotted this problem, despite not being a logician. Logic has to simplify the world. Hence philosophy is quite different from logic. |
23539 | Classical semantics has referents for names, extensions for predicates, and T or F for sentences [Fine,K] |
Full Idea: A precise language is often assigned a classical semantics, in which the semantic value of a name is its referent, the semantic value of a predicate is its extension (the objects of which it is true), and the value of a sentence is True or False. | |
From: Kit Fine (Vagueness: a global approach [2020], 1) | |
A reaction: Helpful to have this clear statement of how predicates are treated. This extensionalism in logic causes trouble when it creeps into philosophy, and people say that 'red' just means all the red things. No it doesn't. |
23544 | Local indeterminacy concerns a single object, and global indeterminacy covers a range [Fine,K] |
Full Idea: Vagueness concerns 'local' indeterminacy, such as whether one man in the lineup is bald, and 'global' indeterminacy, applying to a range of cases, as when it is indeterminate how 'bald' applies to the lineup. But how do these relate? | |
From: Kit Fine (Vagueness: a global approach [2020], 1) | |
A reaction: This puts the focus either on objects or on predicates which are vague. |
23540 | Conjoining two indefinites by related sentences seems to produce a contradiction [Fine,K] |
Full Idea: If 'P is red' and 'P is orange' are indefinite, then 'P is red and P is orange' seems false, because red and orange are exclusive. But if two conjoined indefinite sentences are false, that makes 'P is red and P is red' false, when it should be indefinite. | |
From: Kit Fine (Vagueness: a global approach [2020], 1) | |
A reaction: [compressed] This is the problem of 'penumbral connection', where two indefinite values are still logically related, by excluding one another. Presumably 'P is red and P is of indefinite shape' can be true? Doubtful about this argument. |
23546 | Standardly vagueness involves borderline cases, and a higher standpoint from which they can be seen [Fine,K] |
Full Idea: Standard notions of vagueness all accept borderline cases, and presuppose a higher standpoint from which a judgement of being borderline F, rather than simply being F or being not F, can be made. | |
From: Kit Fine (Vagueness: a global approach [2020], 3) | |
A reaction: He says that the concept of borderline cases is an impediment to understanding vagueness. Proposing a third group when you are struggling to separate two other groups doesn't seem helpful, come to think of it. Limbo cases. |
23542 | Identifying vagueness with ignorance is the common mistake of confusing symptoms with cause [Fine,K] |
Full Idea: We can see Epistemicism [vagueness as ignorance] as a common and misguided tendency to identify a cause with its symptoms. We are unsure how to characterise vagueness, and identify it with the resulting ignorance, instead of explaining it. | |
From: Kit Fine (Vagueness: a global approach [2020], 1) | |
A reaction: Love it. This echoes my repeated plea in these reactions to stop identifying features of reality with the functions which embody them or the patterns they create. We need to explain them, and must dig deeper. |
23541 | Supervaluation can give no answer to 'who is the last bald man' [Fine,K] |
Full Idea: Under supervaluation there should always be someone who is the last bald man in the sequence, but there is always an acceptable way to make some other man the last bald man. | |
From: Kit Fine (Vagueness: a global approach [2020], 1) | |
A reaction: Fine seems to take this as a conclusive refutation of the supervaluation approach. Fine says (p.41) that supervaluation says there is a precisification for every instance. |
23545 | We do not have an intelligible concept of a borderline case [Fine,K] |
Full Idea: We simply have no intelligible notion of local indeterminacy or of a borderline case. | |
From: Kit Fine (Vagueness: a global approach [2020], 2) | |
A reaction: He mentions cases which are near a borderline, and cases which are hard to decide, but denies that these are intrinsically borderline. If there are borderline cases between red and orange, what are the outer boundaries of the border? |
490 | Everything happens by reason and necessity [Leucippus] |
Full Idea: Nothing happens at random; everything happens out of reason and by necessity. | |
From: Leucippus (fragments/reports [c.435 BCE], B002), quoted by (who?) - where? |
23547 | It seems absurd that there is no identity of any kind between two objects which involve survival [Fine,K] |
Full Idea: Pace Parfit and others, it boggles the mind that survival could be independent of any relation of identity between the currently existing object and the objects that subsequently exist. | |
From: Kit Fine (Vagueness: a global approach [2020], 3) | |
A reaction: Yes. If the self or mind just consists of a diachronic trail of memories such that the two ends of the trail have no connection at all, that isn't the kind of survival that any of us want. I want to live my life, not a life. |
22594 | In 1794 France all individual and legal rights were suppressed by the general will [Dunt] |
Full Idea: In the French Revolution the general will replaced democracy, the separation of powers, the rule of law, and individual rights. | |
From: Ian Dunt (How to be a Liberal [2020], 03) | |
A reaction: I had some sympathy with the idea of the general will, but Dunt has persuaded me otherwise. It is the embodiment of the democratic problem of the tyranny of the majority. |
22602 | Over several centuries a set of eight main liberal values was established [Dunt] |
Full Idea: Over the centuries liberal values were established: freedom of the individual, reason, consent in government, individual rights, the separation of powers, protection of minorities, autonomy, and moderation. | |
From: Ian Dunt (How to be a Liberal [2020], 13) | |
A reaction: What's not to like? 'Moderation' might be a sticking point, for anyone who thinks that very large social changes are needed. |
22596 | No government, or the whole nation, can control an individual beyond legitimate scope [Dunt] |
Full Idea: When a government of any sort puts a threatening hand on that part of individual life beyond its proper scope, …even if it were the whole nation, except for the man it is harassing, it would be no more legitimate for that. | |
From: Ian Dunt (How to be a Liberal [2020]), quoted by Ian Dunt - How to be a Liberal 4 | |
A reaction: The obvious question is what counts as 'proper scope' - and who gets to define it? If the individual can define that, then criminals can appeal to this principle. The state must be persuaded of it, then asked to stick to it during conflicts. |
22603 | Laissez-faire liberalism failed to give people the protections and freedoms needed for a good life [Dunt] |
Full Idea: Laissez-faire liberalism failed, because it did not offer people protections and real freedom - against discrimination, insecure work, educational disadvantage, lack of social respect, absence of representation. It was cold, distant, and ineffective. | |
From: Ian Dunt (How to be a Liberal [2020], 13) | |
A reaction: A very nice summary, which I take to be correct. |
22592 | Nationalism pretends that we can only have a single identity [Dunt] |
Full Idea: Nationalism pretends that there is only one identity, that we cannot be more than one thing at once. | |
From: Ian Dunt (How to be a Liberal [2020], Today) | |
A reaction: Dunt is a defender of liberalism, which assumes a wide degree of pluralism. Could I be a British citizen, but love France more than Britain? I don’t see why not, but it is not an ideal situation. |
23543 | We identify laws with regularities because we mistakenly identify causes with their symptoms [Fine,K] |
Full Idea: There is a common tendency to identify a cause with its symptoms. Hence we are not sure how to characterise a law, and so we identify it with the regularities to which it gives rise. | |
From: Kit Fine (Vagueness: a global approach [2020], 1) | |
A reaction: A lovely clear identification of my pet hate, which is superficial accounts of things, which claim to be the last word, but actually explain nothing. |
