22496 | Wisdom only implies the knowledge achievable in any normal lifetime [Foot] |
Full Idea: Wisdom implies no more knowledge and understanding than anyone of normal capacity can and should acquire in the course of an ordinary life. | |
From: Philippa Foot (Natural Goodness [2001], 5) | |
A reaction: Have philosophers stopped talking about wisdom precisely because you now need three university degrees to be considered even remotely good at phillosophy? Hence wisdom is an inferior attainment, because Foot is right. |
14703 | Superficial necessity is true in all worlds; deep necessity is thus true, no matter which world is actual [Schroeter] |
Full Idea: If we have a 'fixedly' operator F, then a sentence is fixedly actually true if it is true no matter which world is designated as actual (which 'he actually won in 2008' fails to be). Maybe '□' is superficial necessity, and FA is 'deep' necessity. | |
From: Laura Schroeter (Two-Dimensional Semantics [2010], 1.2.2) | |
A reaction: Gareth Evans distinguishes 'deep' from 'superficial' necessity. Humberstone and others introduced 'F'. Presumably FA is deeper because it has to pass a tougher test. |
14714 | Contradictory claims about a necessary god both seem apriori coherent [Schroeter] |
Full Idea: It seems apriori coherent that there could be a necessarily existing god, and that there could be no such god - but they can't both be true. Other examples include unprovable mathematical necessities | |
From: Laura Schroeter (Two-Dimensional Semantics [2010], 2.3.4) |
14704 | 2D semantics gives us apriori knowledge of our own meanings [Schroeter] |
Full Idea: Generalized 2D semantics is meant to vindicate the traditional idea that we have apriori access to our own meanings through armchair reflection. | |
From: Laura Schroeter (Two-Dimensional Semantics [2010], 2.1) | |
A reaction: The idea is to split meaning in two, so that we know one part of it a priori. It is an unfashionably internalist view of meaning (which doesn't make it wrong!). |
14706 | Your view of water depends on whether you start from the actual Earth or its counterfactual Twin [Schroeter] |
Full Idea: Your verdicts about whether the stuff on Twin Earth counts as water depends on whether you think of Twin Earth as a hypothesis about your actual environment or as a purely counterfactual possibility. | |
From: Laura Schroeter (Two-Dimensional Semantics [2010], 2.2.3) | |
A reaction: This is the 'two-dimensional semantics' approach to the Twin Earth problem, which splits meaning into two components. Whether you start from the actual world or from Twin Earth, you will rigidly designate the local wet stuff as 'water'. |
14711 | Rationalists say knowing an expression is identifying its extension using an internal cognitive state [Schroeter] |
Full Idea: In rationalist views of meaning, based on the 'golden triangle', to be competent with an expression is to be in an internal cognitive state that puts one in a position to identify its extension in any possible world based only on apriori reflection. | |
From: Laura Schroeter (Two-Dimensional Semantics [2010], 2.3.1) | |
A reaction: This looks like a proper fight-back against modern rampant externalism about meaning. All my intuitions are with internalism, which I think points to a more coherent overall philosophy. Well done, David Chalmers! Even if he is wrong. |
17722 | The concept 'red' is tied to what actually individuates red things [Peacocke] |
Full Idea: The possession conditions for the concept 'red' of the colour red are tied to those very conditions which individuate the colour red. | |
From: Christopher Peacocke (Explaining the A Priori [2000], p.267), quoted by Carrie Jenkins - Grounding Concepts 2.5 | |
A reaction: Jenkins reports that he therefore argues that we can learn something about the word 'red' from thinking about the concept 'red', which is his new theory of the a priori. I find 'possession conditions' and 'individuation' to be very woolly concepts. |
14717 | Internalist meaning is about understanding; externalist meaning is about embedding in a situation [Schroeter] |
Full Idea: Internalists take the notion of meaning to capture an aspect of an individual's current state of understanding, while externalists take the notion of meaning to reflect how an individual is embedded within her social and physical environment. | |
From: Laura Schroeter (Two-Dimensional Semantics [2010], 2.4.3) | |
A reaction: This idea also occurs in discussions of concepts (filed here under 'Thought'). |
14720 | Semantic theory assigns meanings to expressions, and metasemantics explains how this works [Schroeter] |
Full Idea: A semantic theory assigns semantic values (meanings) to particular expressions of the language. In contrast, a metasemantic theory explains why expressions have those semantic values, appealing to facts about speakers and communities. | |
From: Laura Schroeter (Two-Dimensional Semantics [2010], 3.4) | |
A reaction: Presumably some people only want the metasemantic version. I assume that the two are entangled, but I would vote for both. |
14695 | Semantic theories show how truth of sentences depends on rules for interpreting and joining their parts [Schroeter] |
Full Idea: Semantic theories explain how the truth or falsity of whole sentences depends on the meanings of their parts by stating rules governing the interpretation of subsentential expressions and their modes of combination. | |
From: Laura Schroeter (Two-Dimensional Semantics [2010], 1.1.1) | |
A reaction: Somehow it looks as if the mystery of the whole business will still be missing if this project is ever successfully completed. Also one suspects that such a theory would be a fiction, rather than a description of actuality, which is too complex. |
14696 | Simple semantics assigns extensions to names and to predicates [Schroeter] |
Full Idea: The simplest semantic frameworks assign extensions as semantic values of particular expressions. The extension of a name is the thing, of 'cool' is the set of cool things, and sets of ordered pairs for 2-place predicates. The sentence has T or F. | |
From: Laura Schroeter (Two-Dimensional Semantics [2010], 1.1.1) | |
A reaction: The immediate well-known problem is different predicates with the same extensions, such as 'renate' and 'cordate'. Possible worlds semantics is supposed to be an improvement to cover this, and to give a semantics for modal talk as well. Sounds good. |
14697 | 'Federer' and 'best tennis player' can't mean the same, despite having the same extension [Schroeter] |
Full Idea: A simple extensional semantics will assign the same semantic value to 'Roger Federer' and 'world's best tennis player', but they clearly differ in meaning, and if events had unfolded differently they would pick out different people. | |
From: Laura Schroeter (Two-Dimensional Semantics [2010], 1.1.1) | |
A reaction: You would think that this would be too obvious to need pointing out, but it is clearly a view that had a lot of popularity before the arrival of possible worlds. |
14698 | Possible worlds semantics uses 'intensions' - functions which assign extensions at each world [Schroeter] |
Full Idea: In standard possible worlds semantics, the semantic value of an expression is an 'intension', a function that assigns an extension to the expression 'at' every possible world. ...It keeps track of the 'modal profiles' of objects, kinds and properties. | |
From: Laura Schroeter (Two-Dimensional Semantics [2010], 1.1.1) | |
A reaction: Personally I just don't buy a semantics which is entirely based on extensions, even if this has sorted out some more obvious problems of extensionality. When I say someone is 'my hero', I don't just mean to pick out a particular person. |
14699 | Possible worlds make 'I' and that person's name synonymous, but they have different meanings [Schroeter] |
Full Idea: In standard possible worlds semantics the semantic value of Hllary Clinton's utterance of 'I' will be the same as her utterance of 'Hillary Clinton'. But clearly the English word 'I' is not synonymous with the name 'Hillary Clinton'. | |
From: Laura Schroeter (Two-Dimensional Semantics [2010], 1.1.1) | |
A reaction: This problem was spotted by Kaplan, and it has been a chief motivator for the creation of two-dimensional semantics, which some people have then extended into a complete semantic theory. No purely extensional semantics can be right. |
14709 | Possible worlds semantics implies a constitutive connection between meanings and modal claims [Schroeter] |
Full Idea: In standard possible world semantics an expression's intension reflects the modal profile of an object, kind or property, which would establish an important constitutive connection between meanings and modal claims. | |
From: Laura Schroeter (Two-Dimensional Semantics [2010], 2.3.1) | |
A reaction: The central question becomes 'do you need to know a thing's modal profile in order to have a decent understanding of it?', but if you express it that way (my way), then what counts as 'decent' will be relative to all sorts of things. |
14719 | In the possible worlds account all necessary truths are same (because they all map to the True) [Schroeter] |
Full Idea: A problem for a standard possible worlds analysis is that all necessary truths have precisely the same content (the function mapping every world to the True). Hesperus=Phosphorus has the same content as Hesperus=Hesperus-and-2+2=4. | |
From: Laura Schroeter (Two-Dimensional Semantics [2010], 3.3) | |
A reaction: If this is supposed to be a theory of meaning then it has gone very badly wrong indeed. Has modern semantics taken a wrong turning somewhere? Two-dimensionalism is meant to address some of these problems. |
14701 | Array worlds along the horizontal, and contexts (world,person,time) along the vertical [Schroeter] |
Full Idea: In a two-dimensional matrix we array possible circumstances of evaluation (worlds) along the horizontal axis, and possible contexts of utterance (world, person, time) along the vertical axis. | |
From: Laura Schroeter (Two-Dimensional Semantics [2010], 1.1.2) | |
A reaction: This is due to Stalnaker 1978, and is clearest in operation when applied to an indexical such as 'I' in 'I am President'. 'I' is a rigid designator, but depends on context. The grid is filled in with T or F for each utterance in each world. |
14702 | If we introduce 'actually' into modal talk, we need possible worlds twice to express this [Schroeter] |
Full Idea: At first glance necessity and possibility can be fully expressed by quantifying over all possible worlds, but this cannot capture 'Possibly everything actually red is also shiny'. This needs a double-indexed framework, with worlds playing two roles. | |
From: Laura Schroeter (Two-Dimensional Semantics [2010], 1.2.1) | |
A reaction: She points out that this also applies to tense logic, for the notion of 'now'. The point is that we not only need a set of possible worlds, but we also need a procedure (the 'Actuality' operator A or @) for picking out one of the worlds as special. |
14705 | Do we know apriori how we refer to names and natural kinds, but their modal profiles only a posteriori? [Schroeter] |
Full Idea: Perhaps our best way of understanding names and natural kind terms is that we have apriori access to currently associated reference-fixing criterion, but only a posteriori access to the associated modal profile. | |
From: Laura Schroeter (Two-Dimensional Semantics [2010], 2.1) | |
A reaction: This is the 'generalized' view of 2D semantics (covering everything, not just modals and indexicals). I know apriori what something is, but only study will reveal its possibilities. The actual world is easy to talk about, but possible worlds are harder. |
14715 | 2D fans defend it for conceptual analysis, for meaning, and for internalist reference [Schroeter] |
Full Idea: Supporters of generalized two-dimensional semantics agree to defend apriori conceptual analysis in metaphysics, and that 2D captures meaning and not just belief-patterns, and it gives a broadly internalist approach to reference determination. | |
From: Laura Schroeter (Two-Dimensional Semantics [2010], 2.3.4) | |
A reaction: I'm not sure I can evaluate this, but I sort of like conceptual analysis, and the concept of meaning, and fairly internalist views of reference, so I am ripe for the picking. |
14716 | 2D semantics can't respond to contingent apriori claims, since there is no single proposition involved [Schroeter] |
Full Idea: It is objected to 2D semantics that it cannot explain Kripke's cases of contingent apriori truths, for there is no single proposition (construed as a set of possible worlds) that is both apriori and contingent. | |
From: Laura Schroeter (Two-Dimensional Semantics [2010], 2.4.2) | |
A reaction: This sounds like a rather large objection to the whole 2D plan, if it implies that when we say something there is no single proposition that is being expressed. |
23694 | All criterions of practical rationality derive from goodness of will [Foot] |
Full Idea: I want to say, baldly, that there is no criterion for practical rationality that is not derived from that of goodness of will. | |
From: Philippa Foot (Natural Goodness [2001], 1) | |
A reaction: Where does that put the successful and clever criminal? Presumably they are broadly irrational, but narrowly rational - but that is not very clear distinction. She says Kant's concept of the good will is too pure, and unrelated to human good. |
23686 | Moral reason is not just neutral, because morality is part of the standard of rationality [Foot, by Hacker-Wright] |
Full Idea: In her late period she again reverses her thoughts on moral rationalism; …rather than a neutral rationality which fulfils desires, she argues that morality ought to be thought of as part of the standard of rationality itself. | |
From: report of Philippa Foot (Natural Goodness [2001]) by John Hacker-Wright - Philippa Foot's Moral Thought Intro | |
A reaction: This comes much closer to the Greek and Aristotelian concept of logos. They saw morality as inseparable from our judgements about how the world is. All 'sensible' thinking will involve what is good for humanity. |
23693 | Practical rationality must weigh both what is morally and what is non-morally required [Foot] |
Full Idea: Different considerations are on a par, in that judgement about what is required by practical rationality must take account of their interaction: of the weight of the ones we call non-moral as well as those we call moral. | |
From: Philippa Foot (Natural Goodness [2001], 1) | |
A reaction: Her final settled view of rationalism in morality, it seems. The point is that moral considerations are not paramount, because she sees possible justifications for ignoring moral rules (like 'don't lie') in certain practical situations. |
23687 | Moral virtues arise from human nature, as part of what makes us good human beings [Foot, by Hacker-Wright] |
Full Idea: In her later work she offers a view of the relationship of morality to human nature, arguing that the moral virtues are part of what makes us good as human beings. | |
From: report of Philippa Foot (Natural Goodness [2001]) by John Hacker-Wright - Philippa Foot's Moral Thought Intro | |
A reaction: In this phase she talks explicitly of the Aristotelian idea that successful function is the grounding of what is good for any living being, including humans. |
22492 | Virtues are as necessary to humans as stings are to bees [Foot] |
Full Idea: Virtues play a necessary part in the life of human beings as do stings in the life of a bee. | |
From: Philippa Foot (Natural Goodness [2001], 2) | |
A reaction: This presumably rests on the Aristotelian idea that humans are essentially social (as opposed to solitary humans who choose to be social, perhaps in a contractual way, as Plato implies). |
22493 | Sterility is a human defect, but the choice to be childless is not [Foot] |
Full Idea: Lack of capacity to reproduce is a defect in a human being. But choice of childlessness and even celibacy is not thereby shown to be defective choice, because human good is not the same as plant or animal good. | |
From: Philippa Foot (Natural Goodness [2001], 3) | |
A reaction: Is failure to reproduce a defect in an animal? If goodness and virtue derive from function, it is hard to see how deliberate childlessness could be a human good, even if it is not a defect. Choosing to terminate a hereditary defect seems good. |
22491 | Moral evaluations are not separate from facts, but concern particular facts about functioning [Foot] |
Full Idea: A moral evaluation does not stand over against the statement of a matter of fact, but rather has to do with facts about a particular subject matter, as do evaluations of such things as sight and hearing in animals. | |
From: Philippa Foot (Natural Goodness [2001], 1) | |
A reaction: She avoids the word 'function', and only deals with living creatures, but she uses a 'good knife' as an example, and this Aristotelian view clearly applies to any machine which has a function. |
22497 | Deep happiness usually comes from the basic things in life [Foot] |
Full Idea: Possible objects of deep happiness seem to be things that are basic in human life, such as home, and family, and work, and friendship. | |
From: Philippa Foot (Natural Goodness [2001], 6) | |
A reaction: I've not encountered discussion of 'deep' happiness before. I heard of an old man in tears because he had just seen a Purple Emperor butterfly for the first time. She makes it sound very conservative. How about mountaineering achievements? |
22498 | Happiness is enjoying the pursuit and attainment of right ends [Foot] |
Full Idea: In my terminology 'happiness' is understood as the enjoyment of good things, meaning the enjoyment in attaining, and in pursuing, right ends. | |
From: Philippa Foot (Natural Goodness [2001], 6) | |
A reaction: A modified version of Aristotle's view, which she contrasts with McDowell's identification of happiness with the life of virtue. They all seem to have an optimistic hope that the pleasure in being a bit wicked is false happiness. |
23695 | Good actions can never be justified by the good they brings to their agent [Foot] |
Full Idea: There is no good case for assessing the goodness of human action by reference only to good that each person brings to himself. | |
From: Philippa Foot (Natural Goodness [2001], 1) | |
A reaction: She observes that even non-human animals often act for non-selfish reasons. The significance of this is its rejection of her much earlier view that virtues are justified by the good they bring their possessor. |
22499 | We all know that just pretending to be someone's friend is not the good life [Foot] |
Full Idea: We know perfectly well that it is not true that the best life would consist in successfully pretending friendship: having friends to serve one but without being a real friend oneself. | |
From: Philippa Foot (Natural Goodness [2001], 7) | |
A reaction: For some skallywags the achieving of something for nothing seems to be very much the good life, but not many of them want to exploit people who are seen to be their friends. |
22495 | Someone is a good person because of their rational will, not their body or memory [Foot] |
Full Idea: To speak of a good person is to speak of an individual not in respect of his body, or of faculties such as sight and memory, but as concerns his rational will (his 'will as controllable by reason'). | |
From: Philippa Foot (Natural Goodness [2001], 5) | |
A reaction: She more or less agrees with Kant that the only truly good moral thing is a good will, though she has plenty of other criticisms of his views. |
22502 | Refraining from murder is not made good by authenticity or self-fulfilment [Foot] |
Full Idea: If a stranger should come on us when we are sleeping he will not think it all right to kill us. …In human life as it is, this kind of action is not made good by authenticity or self-fulfilment in the one who does it. | |
From: Philippa Foot (Natural Goodness [2001], 7) | |
A reaction: A rare swipe from Foot at existentialism, which she hardly ever mentions. I find it hard to see these existential virtues as in any way moral. It means nothing to other citizens whether one of their number is 'authentic'. |
