| 15957 | Essential definitions show the differences that discriminate things, and make them what they are [Boyle] |
| Full Idea: Essential definitions are such as are taken from the essential differences of things, which constitute them in such a sort of natural bodies, and discriminate them from all those of any other sort. | |
| From: Robert Boyle (The Origin of Forms and Qualities [1666], p.41?), quoted by Peter Alexander - Ideas, Qualities and Corpuscles | |
| A reaction: I don't think this goes as far as the aim Aristotle had in definitions, which was more than merely to 'discriminate' each thing. A full definition explains the thing as well. |
| 20752 | For man, being is not what he is, but what he is going to be [Ortega y Gassett] |
| Full Idea: Being consists not in what it is already, but in what it is not yet, a being that consists in not-yet-being. Everything else in the world is what it is….Man is the entity that makes himself….He has to determine what he is going to be. | |
| From: José Ortega y Gassett (Toward a Philosophy of History [1941], p.112,201-2), quoted by Kevin Aho - Existentialism: an introduction 4 'Problem' | |
| A reaction: [p.112 and 201-2] This seems to be Ortega y Gasset's spin on Heidegger's concept, by adding a temporal dimension to it. |
| 15965 | Boyle attacked a contemporary belief that powers were occult things [Boyle, by Alexander,P] |
| Full Idea: Boyle attacks an idea of powers, held by some modern schoolmen and chemists, that makes powers occult. | |
| From: report of Robert Boyle (The Origin of Forms and Qualities [1666]) by Peter Alexander - Ideas, Qualities and Corpuscles 03.3 | |
| A reaction: [This involves Boyle's famous example of a key having the power to turn a lock] On p.86 Alexander says the 'occult' belief is in affinities, antipathies, attractions and repulsions. How did Boyle explain magnetism? |
| 16735 | In the 17th century, 'disposition' usually just means the spatial arrangement of parts [Boyle, by Pasnau] |
| Full Idea: In Locke and Boyle, 'disposition' and its various cognates are standardly used to refer to the corpuscular structure of a body - the spatial arrangement of its parts - without reflecting any commitment to a dispositional property. | |
| From: report of Robert Boyle (The Origin of Forms and Qualities [1666]) by Robert Pasnau - Metaphysical Themes 1274-1671 23.2 | |
| A reaction: Here as a warning against enthusiasts for dispositional properties misreadigmg 17th century texts to their supposed advantage. Pasnau says none of them believe in dispositional properties or real powers. |
| 16034 | Form is not a separate substance, but just the manner, modification or 'stamp' of matter [Boyle] |
| Full Idea: I understand the word 'form' to mean, not a real substance distinct from matter, but only the matter itself of a natural body, with its peculiar manner of existence [corpuscular structure], which may be called its 'essential modification' or 'stamp'. | |
| From: Robert Boyle (The Origin of Forms and Qualities [1666], p.324), quoted by Jan-Erik Jones - Real Essence §3 | |
| A reaction: I don't think Aristotle ever thought that a form was separate from its matter, let alone qualifying as a substance. On the whole, Boyle attacks scholastic philosophy, rather than Aristotle. |
| 15953 | To cite a substantial form tells us what produced the effect, but not how it did it [Boyle] |
| Full Idea: If it be demanded why rhubarb purges choler, snow dazzles the eyes rather than grass etc., that these effects are performed by substantial forms of the respective bodies is at best but to tell me what is the agent, not how the effect is wrought. | |
| From: Robert Boyle (The Origin of Forms and Qualities [1666], p.47?), quoted by Peter Alexander - Ideas, Qualities and Corpuscles 01.2 | |
| A reaction: This is the problem of the 'virtus dormitiva' of opium (which at least tells you it was the opium what done it). I take Aristotle to have aspired to a lot more than this. He wanted a full definition, which would contain lots of information about the form. |
| 15962 | Boyle's term 'texture' is not something you feel, but is unobservable structures of particles [Boyle, by Alexander,P] |
| Full Idea: Perhaps Boyle's most important technical terms is 'texture'. ...It must not be confused with the way we feel the texture of a surface like sandpaper or velvet; it is rather a structure of unobservable particles and so it is not directly observable. | |
| From: report of Robert Boyle (The Origin of Forms and Qualities [1666]) by Peter Alexander - Ideas, Qualities and Corpuscles 03.2 | |
| A reaction: This is the basis for Alexander's reassessment of what Boyle and Locke meant by a 'secondary quality', which, he says, is a physical feature of objects, not a mental experience. |
| 15964 | Boyle's secondary qualities are not illusory, or 'in the mind' [Boyle, by Alexander,P] |
| Full Idea: There is no suggestion in Boyle that secondary qualities are, unlike primary qualities, somehow illusory, subjective or 'in the mind'. | |
| From: report of Robert Boyle (The Origin of Forms and Qualities [1666]) by Peter Alexander - Ideas, Qualities and Corpuscles 03.3 | |
| A reaction: [Alexander goes on to say that his also applied to Locke] |
| 16736 | Explanation is generally to deduce it from something better known, which comes in degrees [Boyle] |
| Full Idea: Generally speaking, to render a reason of an effect or phenomenon is to deduce it from something else in nature more known than itself, and consequently there may be diverse kinds of degrees of explication of the same thing. | |
| From: Robert Boyle (Certain Physical Essays [1672], II:21), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 23.4 | |
| A reaction: There is a picture of a real explanatory structure to nature, from which we pick bits that interest us for entirely pragmatic reasons. Boyle and I are as one on this matter. |
| 15960 | Explanation is deducing a phenomenon from some nature better known to us [Boyle] |
| Full Idea: Explicating a phenomenon is to deduce it from something else in nature more known to us than the thing to be explained by it. | |
| From: Robert Boyle (The Origin of Forms and Qualities [1666], p.46?), quoted by Peter Alexander - Ideas, Qualities and Corpuscles | |
| A reaction: Interesting that the word 'deduce' is here, beloved of the 'covering law' view. But this may be deduced from the behaviour of other substances, as the iron filing behaviour may be explained by the magnet itself (or perhaps 'laws' of magnetism). |
| 16737 | The best explanations get down to primary basics, but others go less deep [Boyle] |
| Full Idea: Explications be most satisfactory that show how the effect is produced by the more primitive affects of matter (bulk, shape and motion) but are not to be despised that deduce them from more familiar qualities such as heat, weight, fluidity, fermentation. | |
| From: Robert Boyle (Certain Physical Essays [1672], II:22), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 23.4 | |
| A reaction: [Compressed, and continued from Idea 16736] So there is a causal structure, and the best explanations go to the bottom of it, but lesser explanations only go half way down. So a very skimpy explanation ('dormative power') is still an explanation. |
| 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. |
| 20756 | Instead of having a nature, man only has a history [Ortega y Gassett] |
| Full Idea: Man lives in view of the past. Man, in a word, has no nature; what he has is history. Expressed differently: what nature is to things, history is to man. | |
| From: José Ortega y Gassett (Toward a Philosophy of History [1941], p.217), quoted by Kevin Aho - Existentialism: an introduction 5 'Situated' | |
| A reaction: Makes explicit the existentialist denial of human nature. The foundation of ethics can only be total freedom, to choose both yourself and your actions. What is inescapable is the social and culture contexts. What is the role of the 'history'? |
| 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. |
| 15952 | The corpuscles just have shape, size and motion, which explains things without 'sympathies' or 'forces' [Boyle, by Alexander,P] |
| Full Idea: In Boyle's corpuscular philosophy, all material substances are composed of minute particles or corpuscles, with ordinary properties such as shape, size and motion. There was no need for occult relations between them, such as sympathies, or even forces. | |
| From: report of Robert Boyle (The Origin of Forms and Qualities [1666]) by Peter Alexander - Ideas, Qualities and Corpuscles 01.1 |
| 15972 | The corpuscular theory allows motion, but does not include forces between the particles [Boyle, by Alexander,P] |
| Full Idea: Though there is motion, the corpuscles will not be dynamic because the idea of forces between the particles or groups of them does not figure in the theory. | |
| From: report of Robert Boyle (The Origin of Forms and Qualities [1666]) by Peter Alexander - Ideas, Qualities and Corpuscles 5.2 | |
| A reaction: This is the view of Locke, as well as of Boyle. I quote this because I take to it be a particular target of Leibniz's disagreement. |
| 15961 | I don't see how mere moving matter can lead to the bodies of men and animals, and especially their seeds [Boyle] |
| Full Idea: I confess I cannot well conceive how from matter, barely put into motion and left to itself, there could emerge such curious fabricks as the bodies of men and perfect animals, and more admirably contrived parcels of matter, as seeds of living creatures. | |
| From: Robert Boyle (The Sceptical Chemist [1661], p.569), quoted by Peter Alexander - Ideas, Qualities and Corpuscles | |
| A reaction: This is here to show that one of the most brilliant intellects of the seventeenth century thought carefully about this question and couldn't answer it. Natural selection really was a rather clever idea. |
