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. |
6019 | If someone squashed a horse to make a dog, something new would now exist [Mnesarchus] |
Full Idea: If, for the sake of argument, someone were to mould a horse, squash it, then make a dog, it would be reasonable for us on seeing this to say that this previously did not exist but now does exist. | |
From: Mnesarchus (fragments/reports [c.120 BCE]), quoted by John Stobaeus - Anthology 179.11 | |
A reaction: Locke would say it is new, because the substance is the same, but a new life now exists. A sword could cease to exist and become a new ploughshare, I would think. Apply this to the Ship of Theseus. Is form more important than substance? |
21947 | Power is localised, so we either have totalitarian centralisation, or local politics [Foucault, by Gutting] |
Full Idea: Foucault's analysis suggests that meaningful revolution, hence genuine liberation, is impossible: the only alternative to the modern net of micro-centres of power is totalitatian domination. Hence his politics, even when revolutionary, is always local. | |
From: report of Michel Foucault (Discipline and Punish [1977]) by Gary Gutting - Foucault: a very short introduction 8 | |
A reaction: It is hard to disagree with this. |
21946 | Prisons gradually became our models for schools, hospitals and factories [Foucault, by Gutting] |
Full Idea: Foucault's thesis is that disciplinary techniques introduced for criminals became the model for other modern sites of control (schools, hospitals, factories), so that prison discipline pervades all of society. | |
From: report of Michel Foucault (Discipline and Punish [1977]) by Gary Gutting - Foucault: a very short introduction 8 | |
A reaction: Someone recently designed Foucault Monopoly, where every location is a prison. All tightly controlled organisations, such as a medieval monastery, or the Roman army, will inevitably share many features. |
