12 ideas
| 18270 | Choice suggests that intensions are not needed to ensure classes [Coffa] |
| Full Idea: The axiom of choice was an assumption that implicitly questioned the necessity of intensions to guarantee the presence of classes. | |
| From: J. Alberto Coffa (The Semantic Tradition from Kant to Carnap [1991], 7 'Log') | |
| A reaction: The point is that Choice just picks out members for no particular reason. So classes, it seems, don't need a reason to exist. |
| 18263 | The semantic tradition aimed to explain the a priori semantically, not by Kantian intuition [Coffa] |
| Full Idea: The semantic tradition's problem was the a priori; its enemy, Kantian pure intuition; its purpose, to develop a conception of the a priori in which pure intuition played no role; its strategy, to base that theory on a development of semantics. | |
| From: J. Alberto Coffa (The Semantic Tradition from Kant to Carnap [1991], 2 Intro) | |
| A reaction: It seems to me that intuition, in the modern sense, has been unnecessarily demonised. I would define it as 'rational insights which cannot be fully articulated'. Sherlock Holmes embodies it. |
| 18272 | Platonism defines the a priori in a way that makes it unknowable [Coffa] |
| Full Idea: The trouble with Platonism had always been its inability to define a priori knowledge in a way that made it possible for human beings to have it. | |
| From: J. Alberto Coffa (The Semantic Tradition from Kant to Carnap [1991], 7 'What') | |
| A reaction: This is the famous argument of Benacerraf 1973. |
| 20653 | Six reduction levels: groups, lives, cells, molecules, atoms, particles [Putnam/Oppenheim, by Watson] |
| Full Idea: There are six 'reductive levels' in science: social groups, (multicellular) living things, cells, molecules, atoms, and elementary particles. | |
| From: report of H.Putnam/P.Oppenheim (Unity of Science as a Working Hypothesis [1958]) by Peter Watson - Convergence 10 'Intro' | |
| A reaction: I have the impression that fields are seen as more fundamental that elementary particles. What is the status of the 'laws' that are supposed to govern these things? What is the status of space and time within this picture? |
| 18266 | Mathematics generalises by using variables [Coffa] |
| Full Idea: The instrument of generality in mathematics is the variable. | |
| From: J. Alberto Coffa (The Semantic Tradition from Kant to Carnap [1991], 4 'The conc') | |
| A reaction: I like the idea that there are variables in ordinary speech, pronouns being the most obvious example. 'Cats' is a variable involving quantification over a domain of lovable fluffy mammals. |
| 20877 | Errors in moral practice might be inconsistent or inappropriate principles, or inappropriate application [LaFollette] |
| Full Idea: I might make parallel 'mistakes' in ethical deliberation. For instance I might 1) use inconsistent ethical principles, 2) have inappropriate moral standards, and 3) apply moral standards inappropriately. | |
| From: Hugh LaFollette (Introductions in 'Ethics in Practice' [2002], p.005) | |
| A reaction: I would want to get the word 'values' in there somewhere. Dogmatic application of moral rules might indicate a failure of values. |
| 20878 | We can discuss the criteria of a judgment, or the weight given to them, or their application [LaFollette] |
| Full Idea: In discussing a movie you can challenge my criteria, the weight I give to those criteria, or my application of the criteria (the claim that the movie satisfies the criteria). | |
| From: Hugh LaFollette (Introductions in 'Ethics in Practice' [2002], p.008) | |
| A reaction: I can't think of anything missing here, so it is a helpful start. |
| 20881 | The act/omission distinction is important for duties, but less so for consequences [LaFollette] |
| Full Idea: Consequentialists, unlike deontologists, are unlikely to think that the act/omission distinction is fundamentally important. | |
| From: Hugh LaFollette (Introductions in 'Ethics in Practice' [2002], p.021) | |
| A reaction: Not sure where virtue theory fits in here. Virtues tend to be applied more locally, where duty tends to be global. All moral theories must acknowledge that failure to act may be either a good or a bad thing, depending on circumstances |
| 20886 | Are we only obligated by agreement, or should we always help the weak? [LaFollette] |
| Full Idea: A fundamental question in morality is whether we are obligated to help only those we specifically agreed to help, or are we obligated to help others in need, because they are vulnerable? | |
| From: Hugh LaFollette (Introductions in 'Ethics in Practice' [2002], p.061) | |
| A reaction: [He is considering J.J. Thomson's defence of abortion] The first option sounds extraordinary. If I don't make any agreements at all, then I cease to be a moral being? Not help strangers when they fall over? |
| 20879 | Too many options may open us to unwanted pressures, like being paid very little [LaFollette] |
| Full Idea: Having options is not an unadulterated good. Options may make us vulnerable to unwanted pressure from others. For example, having the option to work for less than the minimum wage increases the chances of employers offering less. | |
| From: Hugh LaFollette (Introductions in 'Ethics in Practice' [2002], p.019) | |
| A reaction: [J.D. Velleman is cited for this] A nice point, beginning to articulate my growing feeling that although freedom is generally a virtue, it is the most overrated virtue. |
| 20880 | Should people be forced to make choices? [LaFollette] |
| Full Idea: Should we give people choices they might not want to have? | |
| From: Hugh LaFollette (Introductions in 'Ethics in Practice' [2002], p.020) | |
| A reaction: In personal life we encounter people who force us to make an unwanted choice (choose the wine, when you know nothing about wine). Politically, there is the sneaky move of giving unwanted choices, to disguise absence of desired choices. |
| 18279 | Relativity is as absolutist about space-time as Newton was about space [Coffa] |
| Full Idea: If the theory of relativity might be thought to support an idealist construal of space and time, it is no less absolutistic about space-time than Newton's theory was about space. | |
| From: J. Alberto Coffa (The Semantic Tradition from Kant to Carnap [1991]) | |
| A reaction: [He cites Minkowski, Weyl and Cartan for this conclusion] Coffa is clearly a bit cross about philosophers who draw naive idealist and relativist conclusions from relativity. |
