| 14620 | Theories in logic are sentences closed under consequence, but in truth discussions theories have axioms [Fine,K] |
| Full Idea: It is customary in logic to take a theory to be a set of sentences closed under logical consequence, whereas it is common in discussions of theories of truth to take a theory to be an axiomatized theory. | |
| From: Kit Fine (Semantic Necessity [2010], n8) |
| 14530 | The role of semantic necessity in semantics is like metaphysical necessity in metaphysics [Fine,K, by Hale/Hoffmann,A] |
| Full Idea: Fine's paper argues that the notion of semantic necessity has a role to play in understanding the nature and content of semantics comparable to the role of metaphysical necessity in metaphysics. | |
| From: report of Kit Fine (Semantic Necessity [2010]) by Bob Hale/ Aviv Hoffmann - Introduction to 'Modality' 2 |
| 14618 | Semantics is either an assignment of semantic values, or a theory of truth [Fine,K] |
| Full Idea: On one view, a semantics for a given language is taken to be an assignment of semantic values to its expressions; according to the other, a semantics is taken to be a theory of truth for that language. | |
| From: Kit Fine (Semantic Necessity [2010], Intro) | |
| A reaction: The first is Frege, the second Tarski via Davidson, says Fine. Fine argues against these as the correct alternatives, and says the distinction prevents us understanding what is really going on. He votes for semantics as giving 'semantic requirements'. |
| 14621 | Semantics is a body of semantic requirements, not semantic truths or assigned values [Fine,K] |
| Full Idea: Semantics should be conceived as a body of semantic requirements or facts - and not as a body of semantic truths, or as an assignment of semantic values. | |
| From: Kit Fine (Semantic Necessity [2010], 5) | |
| A reaction: The 'truths' view is Tarski, and the 'values' view is Frege. You'll have to read the Fine paper to grasp his subtle claim. |
| 14622 | Referential semantics (unlike Fregeanism) allows objects themselves in to semantic requirements [Fine,K] |
| Full Idea: What distinguishes the referential position in semantics from Fregeanism is that it makes use of de re semantic facts, in which it is required of an object itself that it enter into certain semantic requirements. | |
| From: Kit Fine (Semantic Necessity [2010], 5) | |
| A reaction: I have a repugnance to any sort of semantics that involves the objects themselves, even when dealing with proper names. If I talk of 'Napoleon', no small Frenchman is to be found anywhere in my sentences. |
| 14619 | The Quinean doubt: are semantics and facts separate, and do analytic sentences have no factual part? [Fine,K] |
| Full Idea: The source of the Quinean scepticism about analytic and synthetic is, first, scepticism over whether we can factor truth into a semantic and a factual component, and (second) if we can, is the factual component ever null? | |
| From: Kit Fine (Semantic Necessity [2010], 1) | |
| A reaction: You certainly can't grasp 'bachelors are unmarried men' if you haven't grasped the full Woosterian truth about men and marriage. But I could interdefine four meaningless words, so that you could employ them in analytic sentences. |
| 22410 | Maybe the unthinkable is a moral category, and considering some options is dishonourable or absurd [Williams,B] |
| Full Idea: One might have the idea that the unthinkable was itself a moral category. ...Regarding certain things even as alternatives is itself something to be regarded as dishonourable or morally absurd. | |
| From: Bernard Williams (A Critique of Utilitarianism [1973], 2) | |
| A reaction: He's very tentative about this, but I think it is a powerful moral idea. See Kekes. He is particularly aiming at utilitarians, who happily assess vile possibilities. |
| 22408 | Consequentialism assumes that situations can be compared [Williams,B] |
| Full Idea: The emphasis on the necessary comparability of situations is a peculiar feature of consequentialism in general. | |
| From: Bernard Williams (A Critique of Utilitarianism [1973], 2) | |
| A reaction: A nice point. Utilitarians might achieve comparison by totting up the happiness in each situation, but once you include the consequences of the consequences the problems are obvious. Was 1789 a good thing? Too early to say. |
| 22411 | For a consequentialist massacring 7 million must be better than massacring 7 million and one [Williams,B] |
| Full Idea: Making the best of a bad job is a consequentialist maxim, and it will have something to say even pn the difference between massacring seven million and massacring seven million and one. | |
| From: Bernard Williams (A Critique of Utilitarianism [1973], 2) | |
| A reaction: If every life counts, the consequentialists have got something right here. Not caring exactly how many were massacred is a sort of callousness (even when the number can't be established). |
| 22409 | We don't have a duty to ensure that others do their duty [Williams,B] |
| Full Idea: If the goodness of the world were to consist in people's fulfilling their obligations, it would by no means follow that one of my obligations was to bring it about that other people kept their obligations | |
| From: Bernard Williams (A Critique of Utilitarianism [1973], 2) | |
| A reaction: If the maxim of my action is 'ensure that everyone does their duty', presumably that can be universalised. Nelson thought so. It just sounds like a hideous world of self-righteous interference. |
| 22407 | Utilitarianism cannot make any serious sense of integrity [Williams,B] |
| Full Idea: Utilitarianism cannot hope to make sense, at any serious level, of integrity. | |
| From: Bernard Williams (A Critique of Utilitarianism [1973], 1) | |
| A reaction: There will be obvious problems with this. 'My whole platoon got killed, but looking on the bright side, I preserved my integrity'. Once a theory commits entirely to one value, it then has no way to make sense of rival values. |
| 1748 | Archelaus was the first person to say that the universe is boundless [Archelaus, by Diog. Laertius] |
| Full Idea: Archelaus was the first person to say that the universe is boundless. | |
| From: report of Archelaus (fragments/reports [c.450 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.Ar.3 |
| 5989 | Archelaus said life began in a primeval slime [Archelaus, by Schofield] |
| Full Idea: Archelaus wrote that life on Earth began in a primeval slime. | |
| From: report of Archelaus (fragments/reports [c.450 BCE]) by Malcolm Schofield - Archelaus | |
| A reaction: This sounds like a fairly clearcut assertion of the production of life by evolution. Darwin's contribution was to propose the mechanism for achieving it. We should honour the name of Archelaus for this idea. |
