6 ideas

1. Philosophy / E. Nature of Metaphysics / 1. Nature of Metaphysics

21959	Metaphysics is the most general attempt to make sense of things [Moore,AW]
	Full Idea: Metaphysics is the most general attempt to make sense of things.
	From: A.W. Moore (The Evolution of Modern Metaphysics [2012], Intro)
	A reaction: This is the first sentence of Moore's book, and a touchstone idea all the way through. It stands up well, because it says enough without committing to too much. I have to agree with it. It implies explanation as the key. I like generality too.

4. Formal Logic / F. Set Theory ST / 5. Conceptions of Set / f. Limitation of Size

13547	Limitation of Size is weak (Fs only collect is something the same size does) or strong (fewer Fs than objects) [Boolos, by Potter]
	Full Idea: Weak Limitation of Size: If there are no more Fs than Gs and the Gs form a collection, then Fs form a collection. Strong Limitation of Size: A property F fails to be collectivising iff there are as many Fs as there are objects.
	From: report of George Boolos (Iteration Again [1989]) by Michael Potter - Set Theory and Its Philosophy 13.5

10. Modality / E. Possible worlds / 1. Possible Worlds / d. Possible worlds actualism

18383	Plantinga says there is just this world, with possibilities expressed in propositions [Plantinga, by Armstrong]
	Full Idea: Plantinga rejects other possible worlds, but adds to our world an uncountable multitude of sets of propositions, each set a way that the world might have been, but is in fact not. (Roughly, for each Lewis world, Plantinga has such a set).
	From: report of Alvin Plantinga (The Nature of Necessity [1974]) by David M. Armstrong - Truth and Truthmakers 07.2
	A reaction: To me it seems as ontologically extravagant to postulate unexpressed propositions as to postulate concrete possible worlds. I think the best line is that there is just the actual world, with the possibilities implied in its dispositions.

10. Modality / E. Possible worlds / 3. Transworld Objects / b. Rigid designation

11891	Possibilities for an individual can only refer to that individual, in some possible world [Plantinga, by Mackie,P]
	Full Idea: Plantinga says for an individual to exist with certain properties in some possible world is simply for it to be true that, had that possible world obtained, that individual would have existed with those properties.
	From: report of Alvin Plantinga (The Nature of Necessity [1974]) by Penelope Mackie - How Things Might Have Been 5.1
	A reaction: This is intended to dissolve the problem of transworld identity, and is certainly a flat rejection of counterparts. I take the point to be that the individual is the key element in defining the possible world, so can't possibly be different.

11. Knowledge Aims / C. Knowing Reality / 3. Idealism / b. Transcendental idealism

21958	Appearances are nothing beyond representations, which is transcendental ideality [Moore,AW]
	Full Idea: Appearances in general are nothing outside our representations, which is just what we mean by transcendental ideality.
	From: A.W. Moore (The Evolution of Modern Metaphysics [2012], B535/A507)

28. God / B. Proving God / 2. Proofs of Reason / a. Ontological Proof

20704	A possible world contains a being of maximal greatness - which is existence in all worlds [Plantinga, by Davies,B]
	Full Idea: Plantinga reformulates Malcolm's argument thus: 1) There is a possible world in which there exists a being with maximal greatness, 2) A being has maximal greatness in a world only if it exists in every world.
	From: report of Alvin Plantinga (The Nature of Necessity [1974], p.213) by Brian Davies - Introduction to the Philosophy of Religion 4 'b Descartes'
	A reaction: This is only Plantinga's starting point, which says nothing about the nature of God, but only that this 'great' being exists in all worlds. I would like to know why it is a 'being' rather than a 'thing'. Malcolm says if it is possible it is necessary.
