| 16519 | No one can conceive of a possible substance, apart from those which God has created [Arnauld] |
| Full Idea: I am much mistaken if there is anyone who dares to say that he can conceive of a purely possible substance, …for although one talks so much of them, one never conceives them except according to the notion of those which God has created. | |
| From: Antoine Arnauld (Letters to Leibniz [1686], 1686.05.13), quoted by David Wiggins - Sameness and Substance 4.2 | |
| A reaction: This idea cashes out in the 'necessitism' of Tim Williamson, and views on the Barcan formulae in modal logic. |
| 18439 | Because things can share attributes, we cannot individuate attributes clearly [Quine] |
| Full Idea: No two classes have exactly the same members, but two different attributes may be attributes of exactly the same things. Classes are identical when their members are identical. ...On the other hand, attributes have no clear principle of individuation. | |
| From: Willard Quine (On the Individuation of Attributes [1975], p.100) |
| 18442 | You only know an attribute if you know what things have it [Quine] |
| Full Idea: May we not say that you know an attribute only insofar as you know what things have it? | |
| From: Willard Quine (On the Individuation of Attributes [1975], p.106) | |
| A reaction: Simple, and the best defence of class nominalism (a very implausible theory) which I have encountered. Do I have to know all the things? Do I not know 'red' if I don't know tomatoes have it? |
| 18441 | No entity without identity (which requires a principle of individuation) [Quine] |
| Full Idea: We have an acceptable notion of class, or physical object, or attribute, or any other sort of object, only insofar as we have an acceptable principle of individuation for that sort of object. There is no entity without identity. | |
| From: Willard Quine (On the Individuation of Attributes [1975], p.102) | |
| A reaction: Note that this is his criterion for an 'acceptable' notion. Presumably that is for science. It permits less acceptable notions which don't come up to the standard. And presumably true things can be said about the less acceptable entities. |
| 18440 | Identity of physical objects is just being coextensive [Quine] |
| Full Idea: Physical objects are identical if and only if coextensive. | |
| From: Willard Quine (On the Individuation of Attributes [1975], p.101) | |
| A reaction: The supposed counterexample to this is the statue and the clay it is made of, which are said to have different modal properties (destroying the statue doesn't destroy the clay). |
| 20508 | How people vote should be on public record, so they can be held accountable [Mill, by Wolff,J] |
| Full Idea: Mill believed in an open vote. People should be held accountable for how they vote, and therefore it should be a matter of public record. | |
| From: report of John Stuart Mill (Representative Government [1861]) by Jonathan Wolff - An Introduction to Political Philosophy (Rev) 3 'Representative' | |
| A reaction: Nowadays it is a mantra that voting should be secret, because coercion is an obvious problem, but MPs vote publicly, and are held accountable for their voting records. People like the mafia seem to make open public voting impossible. |
| 20507 | Voting is a strict duty, like jury service, and must only be aimed at the public good [Mill] |
| Full Idea: The citizen's vote is not a thing in which he has an option; it has no more to do with his personal wishes than the verdict of a juryman. ...he is bound to give it according to his best and most conscientious opinion of the public good. | |
| From: John Stuart Mill (Representative Government [1861], p.299), quoted by Jonathan Wolff - An Introduction to Political Philosophy (Rev) 3 'Representative' | |
| A reaction: Mill was also concerned that voters might pursue 'class interest' (which they currently do, big time). |
| 20505 | Direct democracy is inexperience judging experience, and ignorance judging knowledge [Mill] |
| Full Idea: At its best [direct democracy] is inexperience sitting in judgement on experience, ignorance on knowledge. | |
| From: John Stuart Mill (Representative Government [1861], p.232), quoted by Jonathan Wolff - An Introduction to Political Philosophy (Rev) 4 'Representative' | |
| A reaction: Recent experiments have suggested that inexperienced people can become very good at making large decisions, if they are allowed to consult experts when they want to. See Van Reybrouck's 'Against Elections'. |
| 20504 | People can only participate in decisions in small communities, so representatives are needed [Mill] |
| Full Idea: Since all cannot, in a community exceeding a single small town, participate personally in any but some very minor portions of the public business, it follows that the ideal type of a perfect government must be representative. | |
| From: John Stuart Mill (Representative Government [1861], p.217-8), quoted by Jonathan Wolff - An Introduction to Political Philosophy (Rev) 4 'Representative' | |
| A reaction: Wolff offers Mill as the principal spokesman for representative democracy. It is not only the difficulty of achieving participation, but also the slowness of decision-making. Modern technology may be changing all of this. |
