| 7301 | The phenomenalist says that to be is to be perceivable [Cardinal/Hayward/Jones] |
| Full Idea: Where the idealist says that to be (i.e. to exist) is to be perceived, the phenomenalist says that to be is to be perceivable. | |
| From: Cardinal/Hayward/Jones (Epistemology [2004], Ch.4) | |
| A reaction: This is a nice phenomenalist slogan to add to Mill's well known one (Idea 3583). Expressed in this form, it looks false to me. What about neutrinoes? They weren't at all perceivable until recently. Maybe some physical stuff can never be perceived. |
| 7302 | Linguistic phenomenalism says we can eliminate talk of physical objects [Cardinal/Hayward/Jones] |
| Full Idea: Linguistic phenomenalism argues that it is possible to remove all talk of physical objects from our speech with no loss of meaning. | |
| From: Cardinal/Hayward/Jones (Epistemology [2004], Ch.4) | |
| A reaction: I find this proposal unappealing. My basic objection is that I cannot understand why anyone would refuse to even contemplate the question of WHY I am having a given group of consistent experiences, of (say) a table kind. |
| 7303 | If we lack enough sense-data, are we to say that parts of reality are 'indeterminate'? [Cardinal/Hayward/Jones] |
| Full Idea: The problem with taking sense-data as basic is that some data can appear indeterminate. If we can't discern the colour of someone's eyes, or the number of sides of a complex figure, are we to say that there is no fact about those things? | |
| From: Cardinal/Hayward/Jones (Epistemology [2004], Ch.4) | |
| A reaction: I like that. How many electrons are there in the sun? Such things cannot just be reduced to talk of sense-data, as there is obviously a vast gap between the data and the facts. As usual, ontology and epistemology must be kept separate. |
| 7299 | Primary qualities can be described mathematically, unlike secondary qualities [Cardinal/Hayward/Jones] |
| Full Idea: All the primary qualities lend themselves readily to mathematical or geometric description. ...but it seems that secondary qualities are less amenable to being represented mathematically. | |
| From: Cardinal/Hayward/Jones (Epistemology [2004], Ch.4) | |
| A reaction: As a believer in the primary/secondary distinction, I welcome this point. This is either evidence for the external reality of primary qualities, or an interesting observation about maths. Do we make the primary/secondary distinction because we do maths? |
| 7300 | An object cannot remain an object without its primary qualities [Cardinal/Hayward/Jones] |
| Full Idea: An object cannot lack shape, size, position or motion and remain an object. | |
| From: Cardinal/Hayward/Jones (Epistemology [2004], Ch.4) | |
| A reaction: This points towards the essentialist view (see Idea 5453). This does raise the question of whether an object could lose its colour with impugnity, or the quality of sound that it makes when struck. |
| 7297 | My justifications might be very coherent, but totally unconnected to the world [Cardinal/Hayward/Jones] |
| Full Idea: My beliefs could be well justified in coherentist terms, while not accurately representing the world, and my system of beliefs could be completely free-floating. | |
| From: Cardinal/Hayward/Jones (Epistemology [2004], Ch.3) | |
| A reaction: This nicely encapsulates to correspondence objection to coherence theory. One thing missing from the coherence account is that beliefs aren't chosen for their coherence, but are mostly unthinkingly triggered by experiences. |
| 20289 | Ethics is universalisable - it must involve an impartial and universal view of things [Singer] |
| Full Idea: A distinguishng feature of ethics is that ethical judgements are universalisable. Ethics requires us to go beyond our own personal point of view to a standpoint like that of the impartial spectator who takes a universal point of view. | |
| From: Peter Singer (Practical Ethics [1979], 10) | |
| A reaction: I'm thinking that ethical agents are more 'situated' than that. Suppose a finance minister stole billions in tax and gave it to a poor country. Good from the universal angle, perhaps, but a shocking betrayal of his own community. |
| 20286 | Following an inner voice for morality is irresponsible in a rational agent [Singer] |
| Full Idea: When following conscience means doing as one's 'internal voice' prompts one to do, to follow one's conscience it so abdicate one's responsibility as a rational agent. | |
| From: Peter Singer (Practical Ethics [1979], 09) | |
| A reaction: Seems dead right. An inner voice is far more likely to be your culture and upbringing than to be an absolute moral truth. It may not be entirely wrong, though, to behave as your culture requires. |
| 20282 | The sanctity of a human life depends either on being of our species, or on being a person [Singer] |
| Full Idea: The doctrine of the sanctity of human life has two separate claims, one that there is a special value in the life of a member of our species, and the other that there is a special value in the life of a person. | |
| From: Peter Singer (Practical Ethics [1979], 04) |
| 20278 | 'Marginal utility' says something is more useful if it is in short supply [Singer] |
| Full Idea: The economic principle of marginal utility states that for a given individual a set amount of something is more useful when the individual has little of it than when he has a lot. | |
| From: Peter Singer (Practical Ethics [1979], 02) | |
| A reaction: But individuals may very a lot on this one. 'He can't get enough of X'. I may be desperate to buy 10,000 books, but you may consider such a need ridiculous, so who decides? |
| 20281 | Why should I do anything for posterity? What has posterity ever done for me? [Singer] |
| Full Idea: Most striking is the impact of the contract model on our attitude to future generations. 'Why should I do anything for posterity? What has posterity ever done for me?' would be the view we ought to take. | |
| From: Peter Singer (Practical Ethics [1979], 03) | |
| A reaction: I should bury my mobile phone for future archaeologists, because it will be more valuable then than it is now. Singer cites the disposal of nuclear waste as an instance. |
| 20276 | Conflict of rules might be avoided by greater complexity, or by a hierarchy of rules [Singer] |
| Full Idea: Those who think ethics is a system of rules can rescue their position by finding more complicated and more specific rules which do not conflict, or by ranking the rules in some hierarchical structure to resolve conflicts. | |
| From: Peter Singer (Practical Ethics [1979], 01) | |
| A reaction: The problem is that clear-cut rules seem to produce conflicts. I would have thought that more specific rules would increase that problem. Safety is in generality. |
| 20290 | Psychopaths may just be bored, because they cannot participate in normal emotional life [Singer] |
| Full Idea: Maybe psychopaths are bored because their emotional poverty means that they cannot take interest in, or gain satisfaction from, what for others are the most important things in life: love, family, success in business or professional life, etc. | |
| From: Peter Singer (Practical Ethics [1979], 10) | |
| A reaction: [he cites Hervey Cleckley for this] Maybe boredom is a symptom of some human inadequacy, but it might sometimes be a mark of superiority. It drives people to both creation and destruction. Quite a good account of criminal behaviour. |
| 20288 | You can't condemn violent revolution without assessing the evils it prevents [Singer] |
| Full Idea: It would be one-sided to say that violent revolution is always absolutely wrong, without taking account of the evils that the revolutionaries are trying to stop. | |
| From: Peter Singer (Practical Ethics [1979], 09) | |
| A reaction: This seems like common sense, but there are plenty of right-wing authoritarians who would claim that stable authority has priority over all social wrongs. I think that view is mistaken. But the problem is, how to know the future? |
| 21997 | In Marxism the state will be superseded [Singer] |
| Full Idea: It is a famous Marxist doctrine that the state will be superseded. | |
| From: Peter Singer (Marx [1980], 9) | |
| A reaction: Why is that final state communism rather than anarchism? |
| 20287 | If 49% of the population can be wrong, so can 51% [Singer] |
| Full Idea: The case for majority rule should not be overstated. No sensible democrat would claim that the majority is always right. If 49% of the population can be wrong, so can 51%. | |
| From: Peter Singer (Practical Ethics [1979], 09) | |
| A reaction: Well said! We can't possibly put a figure on when the majority become right. In the recent Brexit referendum hardly anyone seemed to understand the issues very well, so none of us have a clue about who was right. |
| 21993 | Materialist history says we are subject to incomprehensible forces [Singer] |
| Full Idea: The materialist conception of history tells us that human beings are totally subject to forces they do not understand and control. | |
| From: Peter Singer (Marx [1980], 6) | |
| A reaction: How does Marx know the forces? An exceptionally influential idea, because it is a modern commonplace that we have very little control over our own lives (apart from right wingers asserting that 'you can have anything if you really really want it'). |
| 20277 | Equality of interests is a minimal principle, not implying equal treatment [Singer] |
| Full Idea: Equal consideration of interests is a minimal principle of equality in the sense that it does not dictate equal treatment. | |
| From: Peter Singer (Practical Ethics [1979], 02) | |
| A reaction: Do those convicted of serious crime retain equal interests? Should a huge group of people sacrifice all of their interests, because of the powerful interests of one person? |
| 20279 | Equality of opportunity unfairly rewards those lucky enough to have great ability [Singer] |
| Full Idea: Equality of opportunity is not an attractive ideal. It rewards the lucky, who inherit those abilities that allow them to pursue interesting and lucrative careers. | |
| From: Peter Singer (Practical Ethics [1979], 02) | |
| A reaction: He makes it sound like cheating. Singer has a highly individualistic view, but society as a whole needs the development of talent, wherever it can be found. |
| 20285 | If a right entails having the relevant desire, many creatures might have no right to life [Singer] |
| Full Idea: If to have a right one must have the ability to desire that to which one has a right, then to have a right to life one must be able to desire one's own continued existence. | |
| From: Peter Singer (Practical Ethics [1979], 07) | |
| A reaction: The unborn, small infants, and persons in comas may well lack the relevant desire (at least consciously - arguably even a plant has a non-conscious 'desire' or drive for life). The idea that a right entails a conscious desire seems daft. |
| 20284 | Why should a potential person have the rights of an actual person? [Singer] |
| Full Idea: A prince may be a potential king, but he does not have the rights of a king. Why should a potential person have the rights of a person? | |
| From: Peter Singer (Practical Ethics [1979], 06) | |
| A reaction: But the prince is probably accorded special rights, merely on the grounds that he is the potential king. An unborn potential king is always considered as special. |
| 20283 | Killing a chimp is worse than killing a human too defective to be a person [Singer] |
| Full Idea: It seems that killing a chimpanzee is worse than the killing of a gravely defective human who is not a person. ...[p.103] the effects on relatives of the defective human will sometimes constitute additional indirect reasons against killing the human. | |
| From: Peter Singer (Practical Ethics [1979], 05) | |
| A reaction: Singer's most notorious idea. Perhaps we should all carry cards (perhaps combined with donor cards) saying how many people will care if we die. |
| 15150 | The properties of an electron can't be explained just as 'clustering' [Chakravartty on Boyd] |
| Full Idea: Boyd's homeostatic mechanisms are not responsible for the co-instantiation of the mass, charge and spin of an electron. | |
| From: comment on Richard Boyd (Homeostasis, Species and Higher Taxa [1999]) by Anjan Chakravarrty - Inessential Aristotle: Powers without Essences 3 | |
| A reaction: I would have thought that no one has the foggiest idea (unless I have missed something?) about why electrons have those three properties. What is it about electrons that makes them do that? Explanations always run out somewhere. Substratum! |
| 15149 | Properties cluster together, either because of intrinsic relations, or because of an underlying process [Boyd, by Chakravartty] |
| Full Idea: Boyd analyses 'sociability' between properties in terms of 'homeostasis', as causal relations between properties that favour clustering, or underlying processes that favour coinstantiation, or both. | |
| From: report of Richard Boyd (Homeostasis, Species and Higher Taxa [1999]) by Anjan Chakravarrty - Inessential Aristotle: Powers without Essences 3 | |
| A reaction: Chakravarty criticises this claim, by Boyd is clearly onto something. If, like me, you think natural kinds are overrated, you have to like his view. |
