4 ideas

4. Formal Logic / D. Modal Logic ML / 7. Barcan Formula

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.

8. Modes of Existence / D. Universals / 1. Universals

15453	The main rivals to universals are resemblance or natural-class nominalism, or sparse trope theory [Lewis]
	Full Idea: The leading rivals to a theory of universals are resemblance or natural-class nominalism, or sparse trope theory.
	From: David Lewis (Comment on Armstrong and Forrest [1986], p.110)
	A reaction: If that is the complete menu, I choose resemblance nominalism. All discussion of properties in terms of classes is wildly misguided (because properties come first). Why not 'natural' tropes?

9. Objects / C. Structure of Objects / 1. Structure of an Object

15452	We could not uphold a truthmaker for 'Fa' without structures [Lewis]
	Full Idea: We could not, without structures, uphold the principle that every truth has a truthmaker. If Fa is true, the truthmaker is not F, not a, nor both together; not their mereological sum; not a set-theoretic construction. These would exist just the same.
	From: David Lewis (Comment on Armstrong and Forrest [1986], p.109)
	A reaction: This point ought to trouble Lewis, as well as Armstrong and Forrest. If we assert 'Fa', we must (in any theory) have some idea of what unites them, as well as of their separate existence. It must a fact about 'a', not a fact about 'F'.

23. Ethics / C. Virtue Theory / 3. Virtues / a. Virtues

7903	The six perfections are giving, morality, patience, vigour, meditation, and wisdom [Nagarjuna]
	Full Idea: The six perfections are of giving, morality, patience, vigour, meditation, and wisdom.
	From: Nagarjuna (Mahaprajnaparamitashastra [c.120], 88)
	A reaction: What is 'morality', if giving is not part of it? I like patience and vigour being two of the virtues, which immediately implies an Aristotelian mean (which is always what is 'appropriate').
