Definition just needs negation, known variables, conjunction, disjunction, substitution and quantification [Weyl, by Lavine]
|
|
Full Idea:
For mathematics, Weyl arrived (by 1917) at a satisfactory list of definition principles: negation, identification of variables, conjunction, disjunction, substitution of constants, and existential quantification over the domain.
|
|
From:
report of Hermann Weyl (works [1917]) by Shaughan Lavine - Understanding the Infinite V.3
|
|
A reaction:
Lavine summarises this as 'first-order logic with parameters'.

Events are made of other things, and are not fundamental to ontology [Bennett]
|
|
Full Idea:
Events are not basic items in the universe; they should not be included in any fundamental ontology...all the truths about them are entailed by and explained and made true by truths that do not involve the event concept.
|
|
From:
Jonathan Bennett (Events and Their Names [1988], p.12), quoted by Peter Simons - Events 3.1
|
|
A reaction:
Given the variable time spans of events, their ability to coincide, their ability to contain no motion, their blatantly conventional component, and their recalcitrance to individuation, I say Bennett is right.

Over several centuries a set of eight main liberal values was established [Dunt]
|
|
Full Idea:
Over the centuries liberal values were established: freedom of the individual, reason, consent in government, individual rights, the separation of powers, protection of minorities, autonomy, and moderation.
|
|
From:
Ian Dunt (How to be a Liberal [2020], 13)
|
|
A reaction:
What's not to like? 'Moderation' might be a sticking point, for anyone who thinks that very large social changes are needed.

No government, or the whole nation, can control an individual beyond legitimate scope [Dunt]
|
|
Full Idea:
When a government of any sort puts a threatening hand on that part of individual life beyond its proper scope, …even if it were the whole nation, except for the man it is harassing, it would be no more legitimate for that.
|
|
From:
Ian Dunt (How to be a Liberal [2020]), quoted by Ian Dunt - How to be a Liberal 4
|
|
A reaction:
The obvious question is what counts as 'proper scope' - and who gets to define it? If the individual can define that, then criminals can appeal to this principle. The state must be persuaded of it, then asked to stick to it during conflicts.

Laissez-faire liberalism failed to give people the protections and freedoms needed for a good life [Dunt]
|
|
Full Idea:
Laissez-faire liberalism failed, because it did not offer people protections and real freedom - against discrimination, insecure work, educational disadvantage, lack of social respect, absence of representation. It was cold, distant, and ineffective.

Ian Dunt (How to be a Liberal [2020], 13)
|
|
A reaction:
A very nice summary, which I take to be correct.

Facts are about the world, not in it, so they can't cause anything [Bennett]
|
|
Full Idea:
Facts are not the sort of item that can cause anything. A fact is a true proposition (they say); it is not something in the world but is rather something about the world.
|
|
From:
Jonathan Bennett (Events and Their Names [1988], p.22), quoted by Jonathan Schaffer - The Metaphysics of Causation 1.1
|
|
A reaction:
Compare 10361. Good argument, but maybe 'fact' is ambiguous. See Idea 10365. Events are said to be more concrete, and so can do the job, but their individuation also seems to depend on a description (as Davidson has pointed out).
