4739 | In "if and only if" (iff), "if" expresses the sufficient condition, and "only if" the necessary condition [Engel] |
Full Idea: Necessary and sufficient conditions are usually expressed by "if and only if" (abbr. "iff"), where "if" is the sufficient condition, and "only if" is the necessary condition. | |
From: Pascal Engel (Truth [2002], §1.1) | |
A reaction: 'I take my umbrella if and only if it is raining' (oh, and if I'm still alive). There may be other necessary conditions than the one specified. Oh, and I take it if my wife slips it into my car… |
21021 | Keep premises as weak as possible, to avoid controversial difficulties [Nussbaum] |
Full Idea: One should always choose the weakest premises from which one's conclusion follows, rather than saddling the theory with thicker or more controversial premises. | |
From: Martha Nussbaum (Creating Capabilities [2011], 8) | |
A reaction: I like this because it connects the rather vague Ockham's Razor to the logical concept of Thinning. The key point is that a thinner set of premises that prove something will be more persuasive, because critics may reject premises instead of conclusion. |
4737 | Are truth-bearers propositions, or ideas/beliefs, or sentences/utterances? [Engel] |
Full Idea: The tradition of the Stoics and Frege says that truth-bearers are propositions, Descartes and the classical empiricist say they are ideas or beliefs, and Ockham and Quine say they are sentences or utterances. | |
From: Pascal Engel (Truth [2002], §1.1) | |
A reaction: I'm with propositions, which are unambiguous, can be expressed in a variety of ways, embody the 'logical form' of sentences, and could be physically embodied in brains (the language of thought?). |
4750 | The redundancy theory gets rid of facts, for 'it is a fact that p' just means 'p' [Engel] |
Full Idea: The redundancy theory gets rid of facts, for 'it is a fact that p' just means 'p'. | |
From: Pascal Engel (Truth [2002], §2.2) | |
A reaction: But then when you ask what p means, you have to give the truth-conditions for its assertion, and you find you have to mention the facts after all. |
4744 | We can't explain the corresponding structure of the world except by referring to our thoughts [Engel] |
Full Idea: The correspondence theory implies displaying an identity or similarity of structure between the contents of thoughts and the way the world is structured, but we seem only to be able to say that the world's structure corresponds to our thoughts. | |
From: Pascal Engel (Truth [2002], §1.2) | |
A reaction: I don't accept this. The structure of the world gives rise to our thoughts. There is an epistemological problem here (big time!), but that doesn't alter the metaphysical situation of what truth is supposed to be, which is correspondence. |
4738 | The coherence theory says truth is an internal relationship between groups of truth-bearers [Engel] |
Full Idea: The coherence theory of truth says that it is a relationship between truth-bearers themselves, that is between propositions or beliefs or sentences. | |
From: Pascal Engel (Truth [2002], §1.1) | |
A reaction: We immediately begin to wonder how many truth-bearers are required. Two lies can be coherent. It is hard to make thousands of lies coherent, but not impossible. What fixes the critical number. 'All possible propositions' is not much help. |
4745 | Any coherent set of beliefs can be made more coherent by adding some false beliefs [Engel] |
Full Idea: Any coherent set of beliefs can be made more coherent by adding to it one or more false beliefs. | |
From: Pascal Engel (Truth [2002], §1.3) | |
A reaction: A simple but rather devastating point. It is the policeman manufacturing a bogus piece of evidence to clinch the conviction, the scientist faking a single observation to fill in the last corner of a promising theory. |
4755 | Deflationism cannot explain why we hold beliefs for reasons [Engel] |
Full Idea: The deflationist view is silent about the fact that our assertions and beliefs are generally made or held for certain reasons. | |
From: Pascal Engel (Truth [2002], §2.5) | |
A reaction: The point here must be that I attribute strength to my beliefs, depending on how much support I have for them - how much support for their real truth. I scream "That's really TRUE!" when I have very good reasons. |
4753 | Deflationism seems to block philosophers' main occupation, asking metatheoretical questions [Engel] |
Full Idea: Deflationism about truth seems to deprive us of any hope of asking genuinely metatheoretical questions, which are the questions that occupy philosophers most of the time. | |
From: Pascal Engel (Truth [2002], §2.5) | |
A reaction: This seems like the best reason for moving from deflationism to at least minimalism. Clearly one can talk meaningfully about the success of assertions and theories. You can say a sentence is true, but not assert it. |
4751 | Maybe there is no more to be said about 'true' than there is about the function of 'and' in logic [Engel] |
Full Idea: We could compare the status of 'true' with the status of the logical operator 'and' in logic. Once we have explained how it functions to conjoin two propositions, there is not much more to be said about it. | |
From: Pascal Engel (Truth [2002], §2.4) | |
A reaction: A good statement of the minimalist view. I don't believe it, because I don't believe that truth is confined to language. An uneasy feeling I can't put into words can turn out to be true. Truth is a relational feature of mental states. |
4752 | Deflationism must reduce bivalence ('p is true or false') to excluded middle ('p or not-p') [Engel] |
Full Idea: It is said that deflationism cannot even formulate the principle of bivalence, for 'either p is true or p is false' will amount to the principle of excluded middle, 'either p or not-p'. | |
From: Pascal Engel (Truth [2002], §2.4) | |
A reaction: Presumably deflationists don't lost any sleep over this - in fact, it looks like a good concise way to state the deflationist thesis. However, excluded middle refers to a proposition (not-p) that was never mentioned by bivalence. Cf Idea 6163. |
4762 | The Humean theory of motivation is that beliefs may be motivators as well as desires [Engel] |
Full Idea: A problem for the Humean theory of motivation is that it is disputed that beliefs are only representational states, which cannot, unlike desires, move us to act. | |
From: Pascal Engel (Truth [2002], §4.2) | |
A reaction: This is a crucial issue for Humeans and empiricists. Rationalists claim that people act for reasons, so that reasons are intrinsically motivational (like the Form of the Good), and reasons may even be considered direct causes of actions. |
4754 | Our beliefs are meant to fit the world (i.e. be true), where we want the world to fit our desires [Engel] |
Full Idea: Belief is said to 'aim at truth', in the sense that beliefs are the kind of mental states that have to be true for the mind to 'fit' the world (where our desires have the opposite 'direction of fit'; the world is supposed to fit our desires). | |
From: Pascal Engel (Truth [2002], §2.5) | |
A reaction: I don't think it is possible to give a plausible definition of belief without mentioning truth. Hume's account of them as thoughts with a funny feeling attached is ridiculous. Thinking is an activity, not a passive state. |
4763 | 'Evidentialists' say, and 'voluntarists' deny, that we only believe on the basis of evidence [Engel] |
Full Idea: The 'evidentialists' (such as Locke and Hume) deny, and the 'voluntarists' (such as William James) affirm, that we ought to, or at least may, believe for other reasons than evidential epistemic reasons (e.g. for pragmatic reasons). | |
From: Pascal Engel (Truth [2002], §5.2) | |
A reaction: No need to be black-or-white here. Blatant evidence compels belief, but we may also come to believe by spotting a coherence, without additional evidence. We can also be in a state of trying to believe something. But see 4764. |
4746 | Pragmatism is better understood as a theory of belief than as a theory of truth [Engel] |
Full Idea: Pragmatism in general is better construed as a certain conception of belief, rather than as a distinctive conception of truth. | |
From: Pascal Engel (Truth [2002], §1.5) | |
A reaction: Which is why aspiring relativists drift towards the pragmatic theory - because they want to dispense with truth (and hence knowledge), and put mere belief in its place. |
4764 | We cannot directly control our beliefs, but we can control the causes of our involuntary beliefs [Engel] |
Full Idea: Direct psychological voluntarism about beliefs seems to be false, but we can have an indirect voluntary control on many of our beliefs, by manipulating the states in us that are involuntary and which lead to certain beliefs. | |
From: Pascal Engel (Truth [2002], §5.2) | |
A reaction: Very nice! This points two ways - to scientific experiments, which can have compelling outcomes (see Fodor), and to brain-washing, and especially auto-brainwashing (only reading articles which support your favourites theories). What magazines do you take? |
3061 | Anaxarchus said that he was not even sure that he knew nothing [Anaxarchus, by Diog. Laertius] |
Full Idea: Anaxarchus said that he was not even sure that he knew nothing. | |
From: report of Anaxarchus (fragments/reports [c.340 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 09.10.1 |
4759 | Mental states as functions are second-order properties, realised by first-order physical properties [Engel] |
Full Idea: For functionalism mental states as roles are second-order properties that have to be realised in various ways in first-order physical properties. | |
From: Pascal Engel (Truth [2002], §3.3) | |
A reaction: I take that to be properties-of-properties, as in 'bright red' or 'poignantly beautiful'. I am inclined to think (with Edelman) that mind is a process, not a property. |
21007 | Storytelling is never neutral; some features of the world must be emphasised [Nussbaum] |
Full Idea: Storytelling is never neutral; the narrator always directs attention to some features of the world rather than others. | |
From: Martha Nussbaum (Creating Capabilities [2011], 1) | |
A reaction: The audience would be a bit stupid if it insisted on neutrality. |
22688 | The Aristotelian idea that choices can be perceived needs literary texts to expound it [Nussbaum] |
Full Idea: To show forth the Aristotelian claim that 'the decision rests with perception', we need - either side by side with a philosophical outline or inside it - literary texts which display the complexity, indeterminacy, and sheer difficulty of moral choice. | |
From: Martha Nussbaum (The Golden Bowl, and Lit as Moral Philosophy [1983], II) | |
A reaction: Berys Gaut observes that this depends on a particularist view of moral choice (usually seen as Aristotelian), with little interest in principles. |
21836 | Philosophers after Aristotle endorsed the medical analogy for eudaimonia [Nussbaum, by Flanagan] |
Full Idea: Nussbaum says the post-Aristotelian philosophers did much more than simply advancing and refining Aristotle's ethics. They advanced eudaimonics by explicitly endorsing the medical analogy. | |
From: report of Martha Nussbaum (The Therapy of Desire [1994]) by Owen Flanagan - The Really Hard Problem 4 'Eudaimoncs' | |
A reaction: Since Aristotle is all about the successful functioning of the psuche, this idea is obviously implicit in his original texts. It needs a positive concept of mental health, and not a mere absence of mental illness. See the Mindapples campaign. |
21025 | Particularism gives no guidance for the future [Nussbaum] |
Full Idea: Situation ethics offers no guidance for the future. | |
From: Martha Nussbaum (Creating Capabilities [2011], 8) | |
A reaction: Not sure if Situation Ethics is the same as Particularism. Jonathan Danby famously champions the latter. |
21026 | Compassion is unreliable, because it favours people close to us [Nussbaum] |
Full Idea: Daniel Batson's important research has shown us that compassion is not reliable on its own, because it can easily give priority to people close to the self. | |
From: Martha Nussbaum (Creating Capabilities [2011], 8) | |
A reaction: In Britain animal charities receive vastly more money than children's charities, presumably for this very reason. Kittens - you've got to hate them. |
21019 | Social contracts assume equal powers among the participants [Nussbaum] |
Full Idea: All contract theories, including Rawls's, assume a rough equality of physical and mental power among the participants. | |
From: Martha Nussbaum (Creating Capabilities [2011], 4) |
21011 | We shouldn't focus on actual preferences, which may be distorted by injustices [Nussbaum] |
Full Idea: When society puts things out of reach for people, they typically learn not to want those things. ..By defining the social goal in terms of satisfaction of actual preferences, utilitarian approaches often reinforce the status quo, which may be very unjust. | |
From: Martha Nussbaum (Creating Capabilities [2011], 3) | |
A reaction: Maximising happiness is potentially very paternalistic, whereas preference satisfaction is not, which aligns utilitarianism better with liberalism. It is notorious that slaves can be contented with their slavery, and battered wives can remain loyal. |
21008 | Liberalism does not need a comprehensive account of value [Nussbaum] |
Full Idea: The role of political liberalism in my theory requires me to prescind from offering any comprehensive account of value. | |
From: Martha Nussbaum (Creating Capabilities [2011], 2) | |
A reaction: Obviously liberalism has values, but they are the minimum ones of freedom and respect. Liberals have to tolerate some fairly ugly and miserable societies. Can liberals intervene in family life? |
21125 | Liberals must respect family freedom - but families are the great oppressors of women [Nussbaum] |
Full Idea: A liberal society should give people considerable latitude to form families as they choose. …On the other hand the family …is one of the most notorious homes of sex hierarchy, denial of sexual opportunity, and sex-based violence and humiliation. | |
From: Martha Nussbaum (Rawls and Feminism [2003], 03), quoted by Andrew Shorten - Contemporary Political Theory | |
A reaction: The question of how the state might intervene in the family rarely seems to turn up in standard political theory. This idea shows why that is a mistake. |
21012 | Women are often treated like children, and not respected for their choices [Nussbaum] |
Full Idea: Women are often treated as passive dependents, creatures to be cared for (or not), rather than as independent human beings deserving respect for their choices. In other words they are often infantilized. | |
From: Martha Nussbaum (Creating Capabilities [2011], 3) | |
A reaction: Her prime example is from India, but you see the same thing in more subtle forms in the UK, especially among older people, and especially in art galleries. |
21015 | Negative liberty is incoherent; all liberties, to do and to be, require the prevention of interference [Nussbaum] |
Full Idea: The very idea of 'negative liberty' ...is an incoherent idea: all liberties are positive, meaning liberties to do or to be something, which all require the inhibition of interference by others. | |
From: Martha Nussbaum (Creating Capabilities [2011], 3) | |
A reaction: This rejects Isaiah Berlin's well-known claim that negative liberties are good, but positive liberties are far too dangerous. |
21017 | Political freedom is an incoherent project, because some freedoms limit other freedoms [Nussbaum] |
Full Idea: It is unclear whether the idea of promoting freedom is even a coherent political project. Some freedoms limit others. The freedom of rich people to make large donations to political campaigns can limit the equal worth of the right to vote. | |
From: Martha Nussbaum (Creating Capabilities [2011], 4) | |
A reaction: It is not just American right-wingers who over-emphasise 'freedom'. French philosophy seems to be riddled with the same thing. |
21016 | Political and civil rights are not separate from economic and social rights [Nussbaum] |
Full Idea: My approach rejects the distinction, common in the human rights movement, between 'first-generation rights' (political and civil) and 'second-generation rights' (economic and social). The second group are preconditions of the first group. | |
From: Martha Nussbaum (Creating Capabilities [2011], 3) | |
A reaction: [last sentence compressed] This sounds like the sort of point Marx argued for. Nowadays it is feminists who make this point most strongly. |
21009 | Capabilities: Life, Health, Safety, Mental life, Love, Planning, Joining in, Nature, Play, Control [Nussbaum, by PG] |
Full Idea: Ten Capabilities: Life (decent), Health (reproduction, shelter), Safety, Mental life (with education), Love (relationships), Planning (with free beliefs), Joining in (and non-discrimination), Nature (relations to), Play, Control (politics and property). | |
From: report of Martha Nussbaum (Creating Capabilities [2011], 2) by PG - Db (ideas) | |
A reaction: She gives her crucial list in rather wordy form. To have impact it needs to be reduced to brief simple slogans. |
21010 | Justice requires that the ten main capabilities of people are reasonably enabled [Nussbaum] |
Full Idea: The basic claim of my account of social justice is this: respect for human dignity requires that citizens be placed above an ample (specified) threshold of capability in all ten of the areas. | |
From: Martha Nussbaum (Creating Capabilities [2011], 2) | |
A reaction: [The capabilities are given, briefly, in Idea 21009] The one word that bothers me here is 'dignity'. It is very vague, and can, I think, be reduced to much clearer and more obvious concepts. A person lacks dignity when they vomit, in ordinary usage. |
21013 | Capabilities are grounded in bare humanity and agency; qualifying as rational is not needed [Nussbaum] |
Full Idea: The capabilities approach grounds rights claims in bare human birth and minimal agency, not in rationality or any other specific property, something that permits it to recognise the equal human rights of people with cognitive disabilities. | |
From: Martha Nussbaum (Creating Capabilities [2011], 3) | |
A reaction: She says elsewhere that she also sees animals as included in the capabilities approach. This is a rejection of the Kantian grounds for rights (by a well-known Aristotelian). |
21014 | Rights are not just barriers against state interference; governments must affirm capabilities of citizens [Nussbaum] |
Full Idea: A prominent idea, common in the U.S., sees rights as barriers against interfering state action. ...The Capabilities Approach, by contrast, insists that all entitlements involve an affirmative task for government, to actively support capabilities. | |
From: Martha Nussbaum (Creating Capabilities [2011], 3) | |
A reaction: This makes her approach very left wing, by U.S. standards, because it needs higher taxation and a degree of government paternalism. Her approach strikes me as an excellent agenda for a fairly interventionist European liberal party. |
21020 | Any establishment belief system is incompatible with full respect for all citizens [Nussbaum] |
Full Idea: The idea of equal respect is difficult or impossible to render compatible with a religious establishment, even one that is benign and noncoercive. Any established church (or government secularism) denigrates nonbelievers, by stating they are an out-group. | |
From: Martha Nussbaum (Creating Capabilities [2011], 4) | |
A reaction: This sort of applies to membership of anything. She is sort of right, but there is no reason in principle why full respect should not be accorded to any out-group. |
21022 | The Capabilities Approach sees animals as agents, not just as having feelings [Nussbaum] |
Full Idea: The Capabilities Approach sees animals as agents, not as receptacles of pleasure or pain. | |
From: Martha Nussbaum (Creating Capabilities [2011], 8) | |
A reaction: This is in opposition to the utilitarian view. The key consequence is that animals can be victims of injustice, as well as of cruelty. Nice. |
21023 | We should respect animals in the way that we respect the animal nature in humans [Nussbaum] |
Full Idea: If we show respect to our own animal natures, it is simply inconsistent, and a kind of vicious self-promoting of a sort to which Kantians are especially opposed, to refuse the same respect to our fellow creatures. | |
From: Martha Nussbaum (Creating Capabilities [2011], 8) | |
A reaction: Nussbaum says Kant is hopeless on animals, but Christine Korsgaard offers this Kantian approach that demands genuine respect for animals, even though they are not considered rational. Nussbaum says animals are agents. Did Kant respect our animality? |
21024 | It may be no harm to kill an animal which cannot plan for its future [Nussbaum] |
Full Idea: The painless killing of an animal of a species that does not make plans extending into the future may not be a harm: this depends on how we think about the harm of death. | |
From: Martha Nussbaum (Creating Capabilities [2011], 8) | |
A reaction: Very old human beings may have no plans for the future. I, on the other hand, have got lots and lots of plans. Definitely. No one can specify the harm of death. How can it be distinguished from the harm of not being born? |
