10 ideas
| 7500 | Early Greeks cared about city and companions; later Greeks concentrated on the self [Foucault] |
| Full Idea: For early Greeks their techné for life was to take care of the city, of companions (see Plato's 'Alcibiades'). Taking care of yourself for its own sake starts with the Epicureans, and becomes very general in Seneca and Pliny. | |
| From: Michel Foucault (On the Genealogy of Ethics [1983], p.260) | |
| A reaction: In Aristotle the two strike me as ideally balanced - to become a wonderful citizen by looking after yourself. Presumably the destruction of the city-states by Alexander took away the motive, and the aim became more private. |
| 8942 | Lukasiewicz's L3 logic has three truth-values, T, F and I (for 'indeterminate') [Lukasiewicz, by Fisher] |
| Full Idea: In response to Aristotle's sea-battle problem, Lukasiewicz proposed a three-valued logic that has come to be known as L3. In addition to the values true and false (T and F), there is a third truth-value, I, meaning 'indeterminate' or 'possible'. | |
| From: report of Jan Lukasiewicz (Elements of Mathematical Logic [1928], 7.I) by Jennifer Fisher - On the Philosophy of Logic | |
| A reaction: [He originated the idea in 1917] In what sense is the third value a 'truth' value? Is 'I don't care' a truth-value? Or 'none of the above'? His idea means that formalization doesn't collapse when things get obscure. You park a few propositions under I. |
| 9406 | A class is natural when everybody can spot further members of it [Quinton] |
| Full Idea: To say that a class is natural is to say that when some of its members are shown to people they pick out others without hesitation and in agreement. | |
| From: Anthony Quinton (The Nature of Things [1973], 9 'Nat') | |
| A reaction: He concedes a number of problems with his view, but I admire his attempt to at least begin to distinguish the natural (real!) classes from the ersatz ones. A mention of causal powers would greatly improve his story. |
| 15730 | Extreme nominalists say all classification is arbitrary convention [Quinton] |
| Full Idea: Pure, extreme nominalism sees all classification as the product of arbitrary convention. | |
| From: Anthony Quinton (The Nature of Things [1973], 9 'Nat') | |
| A reaction: I'm not sure what the word 'arbitrary' is doing there. Nominalists are not daft, and if they can classify any way they like, they are not likely to choose an 'arbitrary' system. Pragmatism tells the right story here. |
| 15728 | The naturalness of a class depends as much on the observers as on the objects [Quinton] |
| Full Idea: The naturalness of a class depends as essentially on the nature of the observers who classify as it does on the nature of the objects that they classify. ...It depends on our perceptual apparatus, and on our relatively mutable needs and interests. | |
| From: Anthony Quinton (The Nature of Things [1973], 9 'Nat') | |
| A reaction: This seems to translate 'natural' as 'natural for us', which is not much use to scientists, who spend quite a lot of effort combating folk wisdom. Do desirable sports cars constitute a natural class? |
| 9407 | Properties imply natural classes which can be picked out by everybody [Quinton] |
| Full Idea: To say there are properties is to say there are natural classes, classes introduction to some of whose members enables people to pick out others without hesitation and in agreement. | |
| From: Anthony Quinton (The Nature of Things [1973], 9 'Nat') | |
| A reaction: Aristotle would like this approach, but it doesn't find many friends among modern logician/philosophers. We should go on to ask why people agree on these things. Causal powers will then come into it. |
| 15729 | Uninstantiated properties must be defined using the instantiated ones [Quinton] |
| Full Idea: Properties that have no concrete instances must be defined in terms of those that have. | |
| From: Anthony Quinton (The Nature of Things [1973], 9 'Nat') | |
| A reaction: I wonder what the dodo used to smell like? |
| 8520 | An individual is a union of a group of qualities and a position [Quinton, by Campbell,K] |
| Full Idea: Quinton proposes that an individual is a union of a group of qualities and a position. | |
| From: report of Anthony Quinton (The Nature of Things [1973], Pt I) by Keith Campbell - The Metaphysic of Abstract Particulars §5 | |
| A reaction: This seems the obvious defence of a bundle account of objects against the charge that indiscernibles would have to be identical. It introduces, however, 'positions' into the ontology, but maybe that price must be paid. Materialism needs space. |
| 7501 | Why couldn't a person's life become a work of art? [Foucault] |
| Full Idea: Couldn't everyone's life become a work of art? Why should the lamp or the house be an art object, but not our life? | |
| From: Michel Foucault (On the Genealogy of Ethics [1983], p.261) | |
| A reaction: This sounds wonderfully appealing until I try to think how I would implement it. The Augustine move, from sinner to saint, is a possibility, but there is nothing good about sin. The Christian ideal, of colossal self-sacrifice, can be very heroic. |
| 7498 | Greeks and early Christians were much more concerned about food than about sex [Foucault] |
| Full Idea: It is interesting to see the very slow move from the privileging of food, which was overwhelming in Greece, to interest in sex. Early Christians (and rules for monks) were more concerned with food. Sex only dominates from the seventeenth century. | |
| From: Michel Foucault (On the Genealogy of Ethics [1983], p.253) | |
| A reaction: Certainly the Greeks were obsessed with food, and the Sicilian Greeks were notorious for their love of it. Is it simply that food becomes more plentiful, or does female freedom lead to more sex? Puritanism hates the greatest pleasures the most. |
