103 ideas
| 3137 | Varieties of singular terms are used to designate token particulars [Rey] |
| Full Idea: We designate token particulars with singular terms, such as: proper names, numerals, definite descriptions, demonstratives, pronouns or variables. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 1.1.1) |
| 3143 | Physics requires the existence of properties, and also the abstract objects of arithmetic [Rey] |
| Full Idea: Physics is committed to arithmetic, which seems committed to abstract objects such as numbers, and its causal explanations seem to appeal to properties, such as mass and charge. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.3) |
| 13076 | Scholastics treat relations as two separate predicates of the relata [Cover/O'Leary-Hawthorne] |
| Full Idea: The scholastics treated it as a step in the right explanatory direction to analyze a relational statement of the form 'aRb' into two subject-predicate statements, attributing different relational predicates to a and to b. | |
| From: Cover,J/O'Leary-Hawthorne,J (Substance and Individuation in Leibniz [1999], 2.2.1) | |
| A reaction: The only alternative seems to be Russell's view of relations as pure universals, having a life of their own, quite apart from their relata. Or you could take them as properties of space, time (and powers?), external to the relata? |
| 13102 | If you individuate things by their origin, you still have to individuate the origins themselves [Cover/O'Leary-Hawthorne] |
| Full Idea: If we go for the necessity-of-origins view, A and B are different if the origin of A is different from the origin of B. But one is left with the further question 'When is the origin of A distinct from the origin of B?' | |
| From: Cover,J/O'Leary-Hawthorne,J (Substance and Individuation in Leibniz [1999], 7.4.1) | |
| A reaction: There may be an answer to this, in a regress of origins that support one another, but in the end the objection is obviously good. You can't begin to refer to an 'origin' if you can't identify anything in the first place. |
| 13103 | Numerical difference is a symmetrical notion, unlike proper individuation [Cover/O'Leary-Hawthorne] |
| Full Idea: Scholastics distinguished criteria of numerical difference from questions of individuation proper, since numerical difference is a symmetrical notion. | |
| From: Cover,J/O'Leary-Hawthorne,J (Substance and Individuation in Leibniz [1999], 7.4.1) | |
| A reaction: This apparently old-fashioned point appears to be conclusively correct. Modern thinkers, though, aren't comfortable with proper individuation, because they don't believe in concepts like 'essence' and 'substance' that are needed for the job. |
| 13104 | Haecceity as property, or as colourless thisness, or as singleton set [Cover/O'Leary-Hawthorne] |
| Full Idea: There is a contemporary property construal of haecceities, ...and a Scotistic construal as primitive, 'colourless' thisnesses which, unlike singleton-set haecceities, are aimed to do some explanatory work. | |
| From: Cover,J/O'Leary-Hawthorne,J (Substance and Individuation in Leibniz [1999], 7.4.4) | |
| A reaction: [He associates the contemporary account with David Kaplan] I suppose I would say that individuation is done by properties, but not by some single property, so I take it that I don't believe in haecceities at all. What individuates a haecceity? |
| 13100 | Maybe 'substance' is more of a mass-noun than a count-noun [Cover/O'Leary-Hawthorne] |
| Full Idea: We could think of 'substance' on the model of a mass noun, rather than a count noun. | |
| From: Cover,J/O'Leary-Hawthorne,J (Substance and Individuation in Leibniz [1999], 7.3) | |
| A reaction: They offer this to help Leibniz out of a mess, but I think he would be appalled. The proposal seems close to 'prime matter' in Aristotle, which never quite does the job required of it. The idea is nice, though, and should be taken seriously. |
| 13068 | We can ask for the nature of substance, about type of substance, and about individual substances [Cover/O'Leary-Hawthorne] |
| Full Idea: In the 'blueprint' approach to substance, we confront at least three questions: What is it for a thing to be an individual substance? What is it for a thing to be the kind of substance that it is? What is it to be that very individual substance? | |
| From: Cover,J/O'Leary-Hawthorne,J (Substance and Individuation in Leibniz [1999], 1.1.1) | |
| A reaction: My working view is that the answer to the first question is that substance is essence, that the second question is overrated and parasitic on the third, and that the third is the key question, and also reduces to essence. |
| 13069 | The general assumption is that substances cannot possibly be non-substances [Cover/O'Leary-Hawthorne] |
| Full Idea: There is a widespread assumption, now and in the past, that substances are essentially substances: nothing is actually a substance but possibly a non-substance. | |
| From: Cover,J/O'Leary-Hawthorne,J (Substance and Individuation in Leibniz [1999], 1.1.2) | |
| A reaction: It seems to me that they clearly mean, in this context, that substances are 'necessarily' substances, not that they are 'essentially' substances. I would just say that substances are essences, and leave the necessity question open. |
| 13072 | Modern essences are sets of essential predicate-functions [Cover/O'Leary-Hawthorne] |
| Full Idea: The modern view of essence is that the essence of a particular thing is given by the set of predicate-functions essential to it, and the essence of any kind is given by the set of predicate-functions essential to every possible member of that kind. | |
| From: Cover,J/O'Leary-Hawthorne,J (Substance and Individuation in Leibniz [1999], 1.2.2) | |
| A reaction: Thus the modern view has elided the meanings of 'essential' and 'necessary' when talking of properties. They are said to be 'functions' from possible worlds to individuals. The old view (and mine) demands real essences, not necessary properties. |
| 17080 | Modern essentialists express essence as functions from worlds to extensions for predicates [Cover/O'Leary-Hawthorne] |
| Full Idea: The modern essentialist gives the same metaphysical treatment to every grammatical predicate - by associating a function from worlds to extensions for each. | |
| From: Cover,J/O'Leary-Hawthorne,J (Substance and Individuation in Leibniz [1999], 2.2) | |
| A reaction: I take this to mean that essentialism is the view that if some predicate attaches to an object then that predicate is essential if there is an extension of that predicate in all possible worlds. In English, essential predicates are necessary predicates. |
| 13101 | Necessity-of-origin won't distinguish ex nihilo creations, or things sharing an origin [Cover/O'Leary-Hawthorne] |
| Full Idea: A necessity-of-origins approach cannot work to distinguish things that come into being genuinely ex nihilo, and cannot work to distinguish things sharing a single origin. | |
| From: Cover,J/O'Leary-Hawthorne,J (Substance and Individuation in Leibniz [1999], 7.4.1) | |
| A reaction: Since I am deeply suspicious of essentiality or necessity of origin (and they are not, I presume, the same thing) I like these two. Twins have always bothered me with the second case (where order of birth seems irrelevant). |
| 3145 | The Indiscernibility of Identicals is a truism; but the Identity of Indiscernibles depends on possible identical worlds [Rey] |
| Full Idea: Leibniz's Law, the indiscernibility of identicals, is a truism which should not be confused with the more controversial identity of indiscernibles, which depends on the possibility of perfectly replicated universes. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.4) |
| 13081 | Even extreme modal realists might allow transworld identity for abstract objects [Cover/O'Leary-Hawthorne] |
| Full Idea: It might be suggested that even the extreme modal realist can countenance transworld identity for abstract objects. | |
| From: Cover,J/O'Leary-Hawthorne,J (Substance and Individuation in Leibniz [1999], 3.2.2 n46) | |
| A reaction: This may sound right for uncontroversial or well-defined abstracta such as numbers and circles, but even 'or' is ambiguous, and heaven knows what the transworld identity of 'democracy' is! |
| 3172 | Empiricism says experience is both origin and justification of all knowledge [Rey] |
| Full Idea: Two of the key claims of empiricism are that all knowledge must be justified on the basis of experience, and that all knowledge in fact originates in experience. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.3) |
| 3166 | Animal learning is separate from their behaviour [Rey] |
| Full Idea: Rats and monkeys exhibit 'latent learning' (learning just for fun) which is later beneficial. They learn with no consequences, and then can't learn when the good consequences are available. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.1.1) | |
| A reaction: This looks like a bit of a setback for naturalised epistemology and cognitive science, if learning can't be brought within a stimulus-response framework. |
| 13071 | We can go beyond mere causal explanations if we believe in an 'order of being' [Cover/O'Leary-Hawthorne] |
| Full Idea: The philosopher comfortable with an 'order of being' has richer resources to make sense of the 'in virtue of' relation than that provided only by causal relations between states of affairs, positing in addition other sorts of explanatory relationships. | |
| From: Cover,J/O'Leary-Hawthorne,J (Substance and Individuation in Leibniz [1999], 1.1.2) | |
| A reaction: This might best be characterised as 'ontological dependence', and could be seen as a non-causal but fundamental explanatory relationship, and not one that has to depend on a theistic world view. |
| 3232 | Abduction could have true data and a false conclusion, and may include data not originally mentioned [Rey] |
| Full Idea: Abduction moves from some data to a 'best explanation'. It is not deduction because the data could be true but the conclusion false, and it is not induction because the conclusion may involve data not mentioned in the premises. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], p.322) |
| 3128 | It's not at all clear that explanation needs to stop anywhere [Rey] |
| Full Idea: It's not at all clear that explanation needs to stop anywhere. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], Int.2) |
| 3136 | The three theories are reduction, dualism, eliminativism [Rey] |
| Full Idea: There are three main views regarding the ontology of mental phenomena: reductionism, dualism and eliminativism. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 1.1) | |
| A reaction: It is precisely this picture which is rejected by Davidson and co, who want something called 'property dualism', with a unique relationship which is labelled 'supervenient'. Unfortunately there is no analogy for it. Not even beauty and a statue. |
| 3141 | Is consciousness 40Hz oscillations in layers 5 and 6 of the visual cortex? [Rey] |
| Full Idea: Crick and Koch claim that visual consciousness is correlated with a 40Hz oscillation in layers five and six of the primary visual cortex. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.1) | |
| A reaction: Not many people seem to have been enthused by their proposal. The target is the NCC (Neural Correlate of Consciousness), but we would only accept that location if the 'oscillations' seemed in some way special. |
| 3148 | Dualist privacy is seen as too deep for even telepathy to reach [Rey] |
| Full Idea: The privacy that is a serious issue for the dualist is a peculiarly epistemic privacy that not even telepathy or brain fusions would seem to overcome. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.5.4) | |
| A reaction: This is a key idea in the traditional defence of dualism. I'm inclined to think that we are faced with deep privacy not because the mind is so hidden, but because the observer is trapped in NOT being the thing observed. In that sense, rocks are private. |
| 3164 | Intentional explanations are always circular [Rey] |
| Full Idea: There can seem to be no escape from the "intentional circle" - the use of one intentional idiom always seems to presuppose the use of another. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 3.3) | |
| A reaction: The best explanation of this is Conceptual Dualism (Papineau: Thinking about Consciousness). We are locked into dualist concepts because of our long-term ignorance about the brain. |
| 3138 | Arithmetic and unconscious attitudes have no qualia [Rey] |
| Full Idea: The contents of thoughts, beliefs and desires seem quite distinct from qualia. Arithmetic has no particular feeling attached to it, and Freud showed that many propositional attitudes have no feeling at all, as they are unconscious. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 1.1.2) | |
| A reaction: I don't think we should rule out 'pre-conscious' qualia. The fact that advanced human mental capacities like arithmetic have thinned out their qualia doesn't count against qualia being essential to normal mental life. |
| 3142 | Why qualia, and why this particular quale? [Rey] |
| Full Idea: If we allow as a brute fact that certain mental states possess conscious qualitative content, there is still the problem of explaining why they possess one content rather than another (why does this stimulus look RED?). | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.1) | |
| A reaction: This strikes me as the Really Hard Question. The Hard Question is merely 'why are creatures aware of their thoughts?' Personally I don't rule out finding a physical answer to the RHQ, and it is certainly not grounds for drifting into neo-dualism. |
| 3224 | If qualia have no function, their attachment to thoughts is accidental [Rey] |
| Full Idea: If qualia are non-functionally defined objects, then their attachment to their role in my thought would seem to be metaphysically accidental. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 11.4.2) | |
| A reaction: A rock at sea can cause a shipwreck without being defined as 'a shipwrecker'. It is, of course, tautological that if qualia have a 'role' in my thoughts, they must have causal powers, but 'function' is a much trickier concept. |
| 3227 | Are qualia a type of propositional attitude? [Rey] |
| Full Idea: Qualitative experience is just a particular species of propositional attitude. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 11.6.1) | |
| A reaction: This sounds very implausible. If I hear a loud and baffling noise, is a proposition instantly involved? When a subtle change of colour occurs in the sky at sunset, is that 'propositional'? Do slugs formulate propositions when they taste garlic? |
| 3226 | Are qualia irrelevant to explaining the mind? [Rey] |
| Full Idea: Phenomenal objects and properties are no more needed to explain the workings of our mind than are angels needed to explain the motion of the planets. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 11.6.1) | |
| A reaction: The question would be whether 'phenomenal properties' contained unique information, which could therefore influence behaviour. It is also a matter of exactly what you are trying to explain. |
| 3229 | If colour fits a cone mapping hue, brightness and saturation, rotating the cone could give spectrum inversion [Rey] |
| Full Idea: If colour can be modelled as a cone, with points mapped by hue, brightness and saturation, then a rotation could be isomorphic with the hues switched, so we may all experience different hues. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 11.7.1) | |
| A reaction: from Levine |
| 3223 | Self-consciousness may just be nested intentionality [Rey] |
| Full Idea: It is tempting to think that if a system has concepts for nested intentionality and first-person reflection, it has all that's needed for self-consciousness. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 11.2.2) | |
| A reaction: If there nothing more than nested intentionality in complex minds like ours, the top level of the nesting would still have a special status. And if the top level always seemed to stay the same while the lower levels changed, I'd probably call it the Self |
| 20589 | Maybe a person's true self is their second-order desires [Tuckness/Wolf] |
| Full Idea: A second-order desire is a desire about what kind of desires you want to have. ....Some philosophers have argued that we should associate a person's second-order desires with her 'true self'. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 2 'What is') | |
| A reaction: Presumably the buck stops at these second-order desires, though we might request an account of their origin. 'What sort of person do I want to be?' looks like a third-order question. I don't even want to be a saint. Self is nothing to do with desires? |
| 3162 | Experiments prove that people are often unaware of their motives [Rey] |
| Full Idea: Experiments have shown (Nisbett and Wilson 1977) that people's introspective knowledge is a lot less reliable than they suppose. People are sensitive to but entirely unaware of many factors that influence their social behaviour. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 3.2.2) | |
| A reaction: This type of observation rests on an overemphasis on the conscious mind. We are not conscious of liver events, or of deep buried brain events, both of which motivate us. We should only expect introspection to reveal what is fully conscious. |
| 3163 | Brain damage makes the unreliability of introspection obvious [Rey] |
| Full Idea: The most dramatic phenomena undermining the absolute reliability of introspection are those of blindsight and "anosognosia" (unawareness of one's own brain damage). | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 3.2.2) | |
| A reaction: It might depend on what you expected introspection to reveal. If you only expected it to tell you about your consciousness, it would be unreasonable to expect knowledge of blindsight information by introspection. |
| 3195 | If reason could be explained in computational terms, there would be no need for the concept of 'free will' [Rey] |
| Full Idea: If a computational account of reasoning processes could be given, then there is no need to settle the issue of "free will", as reason could get along without it. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.6) |
| 3196 | Free will isn't evidence against a theory of thought if there is no evidence for free will [Rey] |
| Full Idea: We don't need arguments to show that if there were free will then computational accounts of the mind would be inadequate; what is needed is good evidence that there actually exists such free will in the first place. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.6) |
| 3180 | Maybe behaviourists should define mental states as a group [Rey] |
| Full Idea: Defining most mental states seems to requiring citing other mental states - but perhaps behaviourists can define them all simultaneously | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 5.3) | |
| A reaction: This is an interesting strategy for trying to avoid the well known circularity of attempting to define mental states in behavioural terms. Behaviourism won't go away. |
| 3165 | Behaviourism is eliminative, or reductionist, or methodological [Rey] |
| Full Idea: There are three different views concerning behaviourism - the 'radical' view, which aims at eliminativism, the 'analytical' view, which is a reductionist enterprise, and the 'methodological' view, somewhere between the two. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4) | |
| A reaction: The first appears to be ontological, the second about relationships between areas of our language, and the third epistemological. You could attempt language reduction because we can only know behaviour, because that's all there is. |
| 3167 | Animals don't just respond to stimuli, they experiment [Rey] |
| Full Idea: Animals exhibit 'spontaneous alteration' in their behaviour (e.g. varying the route to the food), or improvisation (finding short cuts instead of following training). They use mental maps, or dead reckoning, not just conditioned responses. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.1.4) | |
| A reaction: If we can't even get a decent behaviourist account of animal behaviour, presumably the chances for humans look even less good. 'Black box' behaviourism, rather than the eliminativist version, might allow internal mechanisms to modify responses. |
| 3173 | How are stimuli and responses 'similar'? [Rey] |
| Full Idea: Radical behaviourists say animals emit "similar" responses to "similar" reinforcements, but that is empty without specifying in what respect there is a similarity. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.3) | |
| A reaction: The point is that when you try to specify the similarity you are (supposedly) forced to use mental language to make the distinctions, thus contradicting behaviourism. It is not, though, self-evidently impossible to give a behaviourist specification. |
| 3179 | Behaviour is too contingent and irrelevant to be the mind [Rey] |
| Full Idea: The two main anti-behaviourist intuitions are that mind and behaviour only relate contingently, and that for much mental life (thinking, emotion) the resulting behaviour seems unimportant. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 5.3) | |
| A reaction: Attractive intuitions, but not unquestionable. Since no two states of mind are ever fully identical, we can never test whether the resulting behaviour arises contingently or necessarily. The second point underestimates the physicality of mental life. |
| 3186 | If a normal person lacked a brain, would you say they had no mind? [Rey] |
| Full Idea: If many otherwise ordinary people turned out to have skulls which were empty or filled with oatmeal, would that mean that they didn't have minds? | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 7.1.4) | |
| A reaction: That's a John Locke sort of question, implying that 'persons' are logically independent of their implementation. Personally I would search for a radio receiver, because oatmeal is implausible as a thinker. |
| 3127 | Dualism and physicalism explain nothing, and don't suggest any research [Rey] |
| Full Idea: Neither dualism nor physicalism provides much serious explanation of any mental phenomena, or even much in the way of a program of research. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], Int.2) | |
| A reaction: I'm not sure if people who demand an "explanation of mental phenomena" are quite clear about what it is they want. God might just say "Mental phenomena are just brain events from the brain's point of view". |
| 3188 | Homuncular functionalism (e.g. Freud) could be based on simpler mechanical processes [Rey] |
| Full Idea: So-called 'homuncular functionalism' (such as Freud's or Plato's internal struggles of the soul) needn't lead to an infinite regress if eventually the homunculi become so stupid they could be replaced by a machine. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 7.2.2) | |
| A reaction: from Fodor |
| 3216 | Is the room functionally the same as a Chinese speaker? [Rey] |
| Full Idea: The question for a computational-representation theory about the Chinese Room is: is what is happening inside the room functionally equivalent to what is happening inside a normal Chinese speaker? | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 10.2.1) | |
| A reaction: Certainly the Room lacks morality ('how can I torture my sister?'). It won't spot connections between recent questions. It won't ask itself questions. It will take years to spot absurd questions. |
| 3220 | Searle is guilty of the fallacy of division - attributing a property of the whole to a part [Rey] |
| Full Idea: You should no more attribute understanding of Chinese to this one part of the system than you should ascribe the properties of the entire British Empire to Queen Victoria. This is the fallacy of division. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 10.2.3) | |
| A reaction: This very nicely pinpoints what is wrong with the Chinese Room argument (nice analogy, too). If you carefully introspect what is involved when you 'understand' something, it is immensely complex, though it feels instant and simple. |
| 3206 | One computer program could either play chess or fight a war [Rey] |
| Full Idea: It is always possible to provide incompatible interpretations of formal theories, so that a computer could use the same program one day to play chess, the next to fight a war. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 9.1.3) | |
| A reaction: This seems to present a huge gulf between human chess players (who 'understand' what they are doing) and machines, but I don't accept it. Giving the machine cameras and multi-level software would fix it. |
| 3140 | If you explain water as H2O, you have reduced water, but not eliminated it [Rey] |
| Full Idea: Reduction is not the same as elimination; if chemists reduce water to H2O, or biologists reduce life to a complex chemical process, they have not shown that they don't exist. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 1.2.1) | |
| A reaction: Depends what you mean by 'elimination'. It is important to be clear whether you are eliminating something from life, or from strict philosophical ontology. Ontologists never mention mountains. |
| 3134 | Human behaviour can show law-like regularity, which eliminativism can't explain [Rey] |
| Full Idea: There is clear evidence against eliminative materialism in the law-like correlations found among millions of answers in standardised school tests, for which it can give no explanation. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], Int.3) | |
| A reaction: Not very persuasive. If neural networks got involved in complex competitions with one another, you would expect them to evolve similar tactics. |
| 3200 | Pattern recognition is puzzling for computation, but makes sense for connectionism [Rey] |
| Full Idea: Connectionism is a way of capturing the holism of pattern recognition, as stressed by many critics of computational theories of mind. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.8) | |
| A reaction: I am drawn to the idea that arithmetic derives from pattern recognition, and the latter is basic to all minds (a kind of instant unthinking induction), so this seems to me a win for connectionism. |
| 3201 | Connectionism explains well speed of perception and 'graceful degradation' [Rey] |
| Full Idea: Connectionism is better than other AI strategies at capturing the extraordinary swiftness of perception, and of degrading in a 'graceful' way. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.8) | |
| A reaction: A good theory had better capture the extraordinary swiftness of perception. Also the swiftness of recognition. Compare seeing a surprising old friend in a crowd, and recognising the person you are looking for. |
| 3202 | Connectionism explains irrationality (such as the Gamblers' Fallacy) quite well [Rey] |
| Full Idea: Connectionism offers promising accounts of irrational behaviour, such as people's bias towards positive instances, and their tendency to fall for the gamblers' fallacy. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.8) | |
| A reaction: That is strong support, because the chances of a computational robot having such tendencies is virtually nil, but all humans have the biases referred to (even philosophers). |
| 3199 | Connectionism assigns numbers to nodes and branches, and plots the outcomes [Rey] |
| Full Idea: In connectionism, each node is given an activation level, and each branch a weight, according to possible degree of effect. This results in 'excitatory' and 'inhibitory' connections. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.8) | |
| A reaction: Whether such a system could ever be 'conscious' is not the only interesting question. What could such a system do? Could it ever be good at philosophy? |
| 3150 | Can identity explain reason, free will, non-extension, intentionality, subjectivity, experience? [Rey] |
| Full Idea: Eight properties of mind are problems for the identity theory: rationality, free will, spatiality, privacy, intentionality, essential mentality, subjective content, and the explanatory gap. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.7) | |
| A reaction: The list could go on: poetry, creativity, love, normativity... Actually, these are problems for every theory. |
| 3129 | Physicalism offers something called "complexity" instead of mental substance [Rey] |
| Full Idea: In physicalism the "ghost in the machine" is merely replaced by the "complexity" in it. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], Int.2) | |
| A reaction: This is nonsense. No one thinks that mere complexity generates consciousness. The assumption is that we would begin to understand the mind only if we could somehow map the connections of the brain. |
| 3139 | Some attitudes are information (belief), others motivate (hatred) [Rey] |
| Full Idea: Propositional attitudes divide into two broad types: neutral informational ones (belief, suspicion, imagining), and directional ones which motivate an agent (preference, desire, hate). | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 1.1.2) | |
| A reaction: Since suspicions are motivating, and preferences are informational, this is not a very sharp distinction. An alternative would be to say that there is one type, and sometimes the will gets involved. |
| 3174 | Good grammar can't come simply from stimuli [Rey] |
| Full Idea: Grammatical sensitivity is in no way a physical property of the stimulus, and we can't imagine how to build a device which would produce grammatical structures in response to the environment. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.3) | |
| A reaction: You could try to program it with a set of (say) Aristotelian categories, and mechanisms to sort the environment accordingly. It then has to query its database, in response to practical needs. A doddle. |
| 3171 | Children speak 90% good grammar [Rey] |
| Full Idea: Ninety percent of most young children's utterances are grammatical. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.2.4) | |
| A reaction: This is good evidence for some sort of innate element in the grammar of language. But the accurate grammar is not in a particular language. Good communication must be the driving force in all this. |
| 3213 | Animals may also use a language of thought [Rey] |
| Full Idea: The language of thought need not only be confined to creatures which speak a natural language. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 10.1.1) | |
| A reaction: I take it as axiomatic that our brains are no different in principles and fundamental mechanics from the lowliest of creatures. See Idea 7509. |
| 3170 | We train children in truth, not in grammar [Rey] |
| Full Idea: Very young children have been shown (Brown and Halon 1970) to be 'reinforced' not for their grammar but for the informational content of what they say. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.2.1) | |
| A reaction: This is what you would expect. It doesn't follow that the grammar comes from innate mechanisms, because the pressure to get the information right could impose increasing accuracy in grammar. |
| 3215 | Images can't replace computation, as they need it [Rey] |
| Full Idea: Processing of images and mental models seems to require, and therefore is unlikely to replace, computation and representation. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 10.1.2) | |
| A reaction: A good point. If you are a fan of mental imagery, you still have to explain how we can hold an image, or recall it, or manipulate it. I always, I don't know why, wince at the thought of 'computations' among neurons. |
| 3194 | CRTT is good on deduction, but not so hot on induction, abduction and practical reason [Rey] |
| Full Idea: The computational/representational theory of thought has given a good account of deduction, but mechanical theories of induction, abduction and practical reason are needed in order to make a machine which could reason. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.5) | |
| A reaction: This is the best analysis of rationality that I have found (four components: deduction, induction, abduction, practical reason). I can think of nothing to add, and certainly none of these should be omitted. |
| 3147 | Problem-solving clearly involves manipulating images [Rey] |
| Full Idea: Recent experiments (Shepard 1982) suggest people have imagistic representations they inspect when solving problems. In comparing two rotated images, the time for comparison varies with the angle of rotation. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.5.3) | |
| A reaction: This doesn't prove that they are slowly rotating something. It may just be harder to make the leap to the new shape, when it is 'further away'. Picturing a 20-sided figure, we don't add sides one-by-one. |
| 3175 | Animals map things over time as well as over space [Rey] |
| Full Idea: To map things like food over time, animals must somehow represent events as having temporal properties, and somehow store those representations ready for later use. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.3) | |
| A reaction: If the mechanisms for doing this are basic, then so is the ontology. Objects must be categorised, properties spotted, time-spans correlated etc. 'Represent' needs to be sharp to be useful. |
| 3207 | Simple externalism is that the meaning just is the object [Rey] |
| Full Idea: The oldest version of the externalist theory of meaning is the Fido/Fido theory, according to which the meaning of a representation is the object for which it stands. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 9.2) | |
| A reaction: Modern baptismal theories of reference seem to have taken us back to this, for distinct individuals such as Aristotle, or natural kinds like gold. What, though, does 'Fido' mean to me? Asthma! |
| 3176 | Anything bears a family resemblance to a game, but obviously not anything counts as one [Rey] |
| Full Idea: Anything bears a family resemblance to a game, but obviously not anything counts as one. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.3) |
| 3181 | A one hour gap in time might be indirectly verified, but then almost anything could be [Rey] |
| Full Idea: You couldn't directly verify that the whole universe had stopped for one hour, but you might indirectly verify it (by prediction) - but then almost anything could be very indirectly verified. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 5.4) | |
| A reaction: Does indirect verification include time travel? Or perfect knowledge of quantum theory, and total knowledge of quantum states. Laplace's Hypothesis. |
| 3204 | The meaning of "and" may be its use, but not of "animal" [Rey] |
| Full Idea: The view that the meaning of language of thought expressions is based on their conceptual role (derived from Wittgenstein's idea of meaning as use), is most plausible for the logical connectives like "and", but implausible for, say, "animal". | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 9.1.2) | |
| A reaction: It was the logical connectives that got LW started on this track. If it doesn't work for 'animal' then does that mean we need two different theories? |
| 3205 | Semantic holism means new evidence for a belief changes the belief, and we can't agree on concepts [Rey] |
| Full Idea: Semantic holism is a desperate measure. Belief content would be continually changed by new beliefs, evidence for a belief would change the target belief, and no two people would ever agree on concepts. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 9.1.2) | |
| A reaction: It is far more plausible to say language is a bit on the holistic side. Total holism is mad. |
| 3209 | Causal theories of reference (by 'dubbing') don't eliminate meanings in the heads of dubbers [Rey] |
| Full Idea: Causal histories may have some role to play in a theory of reference, but the chain of causation requires internal characterisations at each stage, and the original dubber had one thing rather than another in mind when dubbing. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 9.2.1) | |
| A reaction: The modern view of direct reference seems to prefer social context rather than a complete causal chain. |
| 3210 | If meaning and reference are based on causation, then virtually everything has meaning [Rey] |
| Full Idea: What is special about meaning? If meaning and reference are just the result of causal chains, almost everything will mean something, since almost everything is reliably caused by something. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 9.2.2) | |
| A reaction: It would be insane to think that all causal events produced meanings. It is probably better not to mention causation at all when discussing meaning. |
| 3149 | Referential Opacity says truth is lost when you substitute one referring term ('mother') for another ('Jocasta') [Rey] |
| Full Idea: Referential Opacity says you cannot preserve truth if you substitute one referring term for another ('Oedipus desires Jocasta', 'Oedipus desires his mother'). | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.5.6) | |
| A reaction: ….That is, in the context of expressing a propositional attitude. 'Oedipus desired his mother' was true. This idea requires some ignorance on the part of the person expressing the thought. |
| 3169 | A simple chaining device can't build sentences containing 'either..or', or 'if..then' [Rey] |
| Full Idea: Bifurcated logical particles (either/or, if/then) are in principle beyond the power of any local chaining device to build sentences. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.2.1) | |
| A reaction: True in natural languages, but not in formal ones? If P then either if-Q-then-R or if-S-then-T. Is that chaining? If rain, then if light then puddles, or if heavy then floods. Hm. |
| 3221 | Our desires become important when we have desires about desires [Rey] |
| Full Idea: What gives people's desires certain moral importance is the fact that they have desires about those desires. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 11.1) | |
| A reaction: from Frankfurt |
| 20583 | If maximising pleasure needs measurement, so does fulfilling desires [Tuckness/Wolf] |
| Full Idea: Just as hedonists need a way to compare pleasures, so desire fulfilment theorists need a way to compare the fulfilment of desires. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 1 'Is happiness') | |
| A reaction: A nice point. We picture desire fulfilment as just ticking it off when it is achieved, but if your desire is for a really nice house, the achievement of that can be pretty vague. |
| 20584 | Desire satisfaction as the ideal is confused, because we desire what we judge to be good [Tuckness/Wolf] |
| Full Idea: Critics of desire satisfaction theory argue that it gets things backward. We desire things because we already think they are good in some way. Desire theory puts it the other way round. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 1 'Is happiness') | |
| A reaction: Not persuasive. It looks to me as if skiing is a spendid pastime, but I have no desire to do it. More exercise would even be a good for me, but I don't desire that either. Indeed, right now I desire more cake, which is very naughty. |
| 20598 | In a democracy, which 'people' are included in the decision process? [Tuckness/Wolf] |
| Full Idea: In any democratic state, who are 'the people' who get to rule themselves? That is, who gets to participate in the public decision process, and who is excluded? | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'What is') | |
| A reaction: In the modern world this may be clear-cut when a democracy gets started, but people move around so much more that every democracy is faced with new types of residents. Then there is age, criminality, mental health... |
| 20614 | People often have greater attachment to ethnic or tribal groups than to the state [Tuckness/Wolf] |
| Full Idea: Some states have a number of different ethnic or tribal groups. Often these attachments are much stronger than the attachment people feel towards the state. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 6 'Membership') | |
| A reaction: In Britain I fine people torn between attachments to the UK and to England or Wales or Scotland or NI. Attachments to football clubs are much stronger than most patriotism. Or attachment to a particular locality. Does it matter? |
| 20596 | For global justice, adopt rules without knowing which country you will inhabit [Tuckness/Wolf] |
| Full Idea: Imagine a new original position where we adopted rules for global justice without knowing which country we would inhabit. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 4 'Cosmopolitan') | |
| A reaction: Nice question. North Korea!! Rawls says it is only within a nation, because there is a co-operative enterprise going on. That is, I presume, that the choosers involved are a 'people'. See Kant's 'Perpetual Peace' for an alternative. |
| 20593 | The veil of ignorance ensures both fairness and unanimity [Tuckness/Wolf] |
| Full Idea: The veil of ignorance ensures that the original position is fair, but it also guarantees that agreement will be unanimous (which would be impossible if each person insisted that justice should match her own conception). | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 4 'Original') | |
| A reaction: Not clear about this. If I choose very cautiously, but others choose very riskily, and they win, why I should I fall in with their unanimity? That can only be if we agree to be unanimous in backing the result. Like a democratic election? |
| 20608 | Unjust institutions may be seen as just; are they legitimate if just but seen as unjust? [Tuckness/Wolf] |
| Full Idea: Legitimacy and perceived legitimacy do not always go together: people can believe that their institutions are just, but they may be wrong. Is the reverse also possible? Can institutions be legitimate if people believe they are not? | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'What are') | |
| A reaction: Nice thoughts. An institution cannot be just merely because it is seen that way (if someone gets away with rigging an election). If they are just but seen as unjust, I presume they are legitimate (which is objective), but disfunctional. |
| 20597 | If winning elections depends on wealth, we have plutocracy instead of democracy [Tuckness/Wolf] |
| Full Idea: If we let people's influence on election outcomes depend on their wealth, then we don't have a democracy any more. We have a plutocracy, where the people who have all the wealth have all the political power too. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'Intro') | |
| A reaction: [see Michael Walzer on 'complex equality'] This is startling true in the United States, but still somewhat true elsewhere. Being wealthy enough to control the media is the key in modern democracies. |
| 20606 | Epistemic theories defend democracy as more likely to produce the right answer [Tuckness/Wolf] |
| Full Idea: According to epistemic theories of democracy, democratic outcomes are justified because they are more likely to be true or right than the choice of the individual. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'Do the people') | |
| A reaction: Bear in mind Condorcet's proof that this claim is only correct if individuals have a better than 50% chance of being right, which may be so on obvious things, but is implausible for decisions like going to war. |
| 20600 | Which areas of public concern should be decided democratically, and which not? [Tuckness/Wolf] |
| Full Idea: Are there areas which are excluded from democratic decision making? Or should all issues of public concern be decided through a democratic process? | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'What is') | |
| A reaction: Crucially, are we discussing direct democracy, or representative democracy? In Britain all major decisions are made by the cabinet. Our representatives appoint leaders, who then appoint the decision makers. Judiciary is non-democratic. |
| 20609 | If several losing groups would win if they combine, a runoff seems called for [Tuckness/Wolf] |
| Full Idea: It is possible that the people who supported several losing candidates might have joined forces and had a majority. For that reason, many countries have a runoff election. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'Does democracy') | |
| A reaction: The problem is that there is no rationale as to who stands in an election. If their views are evenly spread, the first result seems OK. If there are five left-wingers and one right-winger, a runoff seems to be produce a more just result. |
| 20605 | Rights as interests (unlike rights as autonomy) supports mandatory voting [Tuckness/Wolf] |
| Full Idea: If rights concern people's interests, that might support mandatory voting, but if rights rely on protecting autonomy that might oppose it. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'Interest') | |
| A reaction: I approach it from the other end, and am inclined to support mandatory voting, which suggests I am more concerned about interests than about autonomy. |
| 20599 | How should democratic votes be aggregated? Can some person's votes count for more? [Tuckness/Wolf] |
| Full Idea: A major question for democracy is how are the contributions of different people aggregated into a collective decision? Must votes have equal weight and consideration, or is it permissible for different people's votes to count differently? | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'What is') | |
| A reaction: Mill hoped that wise and knowledgeable people would have a strong influence over the others, but we have recently moved into the post-truth era, where we are swamped by bogus facts. Does that strengthen the case for elite voting? |
| 20601 | Discussion before voting should be an essential part of democracy [Tuckness/Wolf] |
| Full Idea: According to advocates of deliberative democracy, people should have an opportunity to talk and reason with one another before votes are cast. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'Who gets') | |
| A reaction: This is now done on Facebook and Twitter, but no one thinks that is sufficient. We will never again persuade most people to actually meet up and discuss issues. |
| 20613 | We have obligations to our family, even though we didn't choose its members [Tuckness/Wolf] |
| Full Idea: Many of our most important obligations are things we did not consent to. If you think you have obligations to your family, did you choose to have them as family members? | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 6 'Gratitude') | |
| A reaction: A question that gets close to the heart of the communitarian ideal, I think. We choose to have children, and we bring them up, but even then we don't choose who our children are. |
| 20586 | Free speech does not include the right to shout 'Fire!' in a crowded theatre [Tuckness/Wolf] |
| Full Idea: Oliver Wendell Holmes (in 1919) noted that freedom of speech does not include the right to shout 'Fire!' in a crowded theatre. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 1 'Conflict') | |
| A reaction: The point here is that such irresponsible free speech does not even require legislation, and there is probably already some law under which the perpetrator could be prosecuted. |
| 20587 | Most people want equality because they want a flourishing life [Tuckness/Wolf] |
| Full Idea: If we want equality so much, we find that it is often because they think of equality as a prerequisite for a certain kind of flourishing life. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 1 'Happiness') | |
| A reaction: Most writers seem to agree that we don't want equality for its own sake. In what respects do we want to be equal? Why not equal in hair colour? Hence it looks as if equality drops out. I would aim to derive it from the social virtue of respect. |
| 20591 | If there is no suffering, wealth inequalities don't matter much [Tuckness/Wolf] |
| Full Idea: It is hard to get worked up over wealth inequalities if no one is suffering from them! | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 3 'Deprivation') | |
| A reaction: The more the poorer group resent the inequality, the more they suffer. When is resenting huge inequalities in wealth justified? It depends how the big wealth was obtained. |
| 20602 | Some rights are 'claims' that other people should act in a certain way [Tuckness/Wolf] |
| Full Idea: A 'claim right' is one in which the person asserting the right makes a claim on others to act or not act in a certain way. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'Claim') | |
| A reaction: There seems to be a crucial distinction between rights which entail obligations on some individual or institution, and those which don't. Contracts (including employment contracts) generate duties on the parties. |
| 20604 | Choice theory says protecting individual autonomy is basic (but needs to cover infants and animals) [Tuckness/Wolf] |
| Full Idea: Choice theorists hold that rights protect our rights to make autonomous judgements, because our basic right to autonomy must be protected, The theory has a problem with people unable to exercise autonomy (such as infants and animals). | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'Interest') | |
| A reaction: The problem of infants and animals looks like a decisive objection to me. We obviously don't protect dangerous or hostile autonomous judgements, and it is not clear why protecting stupid autonomy should be basic. |
| 20603 | One theory (fairly utilitarian) says rights protect interests (but it needs to cover trivial interests) [Tuckness/Wolf] |
| Full Idea: Interest theorists hold that rights serve to protect people's important interests. This is closely allied with utilitarian values. The theory has difficulty accounting for relatively trivial interests (like owning a lemonade you bought). | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'Interest') | |
| A reaction: This sounds more plausible than choice theory (Idea 20604). It is obvious that infants must have rights. The lemonade problem seems to demand some sort of rule utilitarianism. Sidgwick looks promising. Rights can also be moral claims. |
| 20607 | Having a right does not entail further rights needed to implement it [Tuckness/Wolf] |
| Full Idea: Possession of a right (such as self-defence) does not always imply that one has additional rights to whatever they need (such as a handgun) in order to exercise the first right. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'Is there') | |
| A reaction: The right to life entails a right to food (but not to a banquet), so it is a stronger right than self-defence. I have no obligation to let you defend yourself against me, but I may have an obligation to feed you if you are starving. (Distinction here?) |
| 20612 | If being subject to the law resembles a promise, we are morally obliged to obey it [Tuckness/Wolf] |
| Full Idea: One of the more common reasons people will give for having a moral obligation to obey the law is consent. ...It rests on the intuitively appealing idea of an analogy with a promise. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 6 'Consent') | |
| A reaction: [They cite Locke and Jefferson] In Locke's case it has to be a 'tacit' promise, which is more realistic. In real life we have problems with people who 'said' they would do something. They are often accused of promising, when they didn't. |
| 20611 | If others must obey laws that we like, we must obey laws that they like? [Tuckness/Wolf] |
| Full Idea: If we expect others to obey the laws we think just, do we have an obligation to obey the laws that other people think just? | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 6 'What should') | |
| A reaction: Depends whether you have to be consistent about everything. I'm picky about which laws I obey, but I'm not going to tell you that, in case you get the same idea. Free riders. |
| 20610 | Instead of against natural law, we might assess unjust laws against the values of the culture [Tuckness/Wolf] |
| Full Idea: Do we need natural law theory in order to make sense of the idea that laws can be unjust? Perhaps not: we might consider whether laws are consistent with the values of the culture or society where they apply. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'Unjust') | |
| A reaction: So were the wicked laws passed by the Nazis consistent with 1930s German culture? Impossible to say. |
| 20617 | How should the punishment fit the crime (for stealing chickens?) [Tuckness/Wolf] |
| Full Idea: One criticism of the retributive theory of punishment is that it is hard to know how to fit the punishment to the crime. What punishment should correspond to stealing chickens? | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 7 'Rationales') | |
| A reaction: The ancient world was more keen on restitution for such crimes, which makes much better sense. Buy them some chickens, plus twenty percent. |
| 20615 | Just wars: resist aggression, done on just cause, proportionate, last resort, not futile, legal [Tuckness/Wolf] |
| Full Idea: Classical just war theory: resist aggression; just cause must be the real reason; must be proportionate; last resort; not futile; made by a nation's authority. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 9 'Ius ad') | |
| A reaction: [My squashed summary of Tuckness and Wolf] A very helpful list, from Cicero, Augustine and Aquinas. So where is the sticking point for pacifists? Presumably it is never the last resort, and aggression should not answer aggression. |
| 20616 | During wars: proportional force, fair targets, fair weapons, safe prisoners, no reprisals [Tuckness/Wolf] |
| Full Idea: Classical just war theory during a war: force must be proportional; only legitimate targets; avoid prohibited weapons; safety for prisoners of war; no reprisals. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 9 'In the conduct') | |
| A reaction: What of massacre if a besieged city refuses to surrender? It was commonplace, and sometimes the only way to achieve victory. What if the enemy breaks all the rules? Nice rules though. At the heart of civilisation. |
| 20620 | If minority views are accepted in debate, then religious views must be accepted [Tuckness/Wolf] |
| Full Idea: It is unfair to exclude religious arguments from the public square because they are not accepted by everyone, unless other views that are not accepted by everyone are also excluded. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 9 'fairly') | |
| A reaction: Raises the obvious problems of a huge group in the grips of a fairly crazy view, and a tiny group (e.g. specialist scientists) in possession of a correct view. You can't just assess it on the size of the group. You can be wrong but reasonable. |
| 20619 | Is abortion the ending of a life, or a decision not to start one? [Tuckness/Wolf] |
| Full Idea: One group may consider abortion as a decision to end a life, while another may regard it as the decision not to start one. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 8 'Hard I') | |
| A reaction: An early foetus is 'life', but is it 'a life'? Is a blade of grass 'a life'? Is a cell in a body 'a life'? |
