6 ideas

2. Reason / D. Definition / 1. Definitions

11257	The Pythagoreans were the first to offer definitions [Politis, by Politis]
	Full Idea: Aristotle praises the Pythagoreans for being the first to offer definitions.
	From: report of Vassilis Politis (Aristotle and the Metaphysics [2004]) by Vassilis Politis - Aristotle and the Metaphysics 2.4
	A reaction: This sounds like a hugely important step in the development of Greek philosophy which is hardly ever mentioned.

3. Truth / A. Truth Problems / 4. Uses of Truth

11235	'True of' is applicable to things, while 'true' is applicable to words [Politis]
	Full Idea: It is crucial not to confuse 'true' with 'true of'. 'True of' is applicable to things, while 'true' is applicable to words.
	From: Vassilis Politis (Aristotle and the Metaphysics [2004], 1.4)
	A reaction: A beautifully simple distinction which had never occurred to me, and which (being a thoroughgoing realist) I really like.

7. Existence / A. Nature of Existence / 3. Being / e. Being and nothing

11277	Maybe 'What is being? is confusing because we can't ask what non-being is like [Politis]
	Full Idea: We may be unfamiliar with the question 'What is being?' because there appear to be no contrastive questions of the form: how do beings differ from things that are not beings?
	From: Vassilis Politis (Aristotle and the Metaphysics [2004], 4.1)
	A reaction: We can, of course, contrast actual beings with possible beings, or imaginary beings, or even logically impossible beings, but in those cases 'being' strikes me as an entirely inappropriate word.

9. Objects / B. Unity of Objects / 2. Substance / a. Substance

16776	Substance is an intrinsic thing, so parts of substances can't also be intrinsic things [Duns Scotus]
	Full Idea: Substance ...is an ens per se. No part of a substance is an ens per se when it is part of a substance, because then it would be a particular thing, and one substance would be a particular thing from many things, which does not seem to be true.
	From: John Duns Scotus (In Praed. [1300], 15.1), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 26.1
	A reaction: The tricky bit is 'when it is a part of a substance', meaning a substance must cease to be a substance when it is subsumed into some greater substance. Maybe. Drops of water? Molecules? Bricks? Cells?

9. Objects / B. Unity of Objects / 2. Substance / d. Substance defined

19347	Substance needs independence, unity, and stability (for individuation); also it is a subject, for predicates [Perkins]
	Full Idea: For individuation, substance needs three properties: independence, to separate it from other things; unity, to call it one thing, rather than an aggregate; and permanence or stability over time. Its other role is as subject for predicates.
	From: Franklin Perkins (Leibniz: Guide for the Perplexed [2007], 3.1)
	A reaction: Perkins is describing the Aristotelian view, which is taken up by Leibniz. 'Substance' is not a controversial idea, if we see that it only means that the world is full of 'things'. It is an unusual philosopher wholly totally denies that.

9. Objects / D. Essence of Objects / 7. Essence and Necessity / b. Essence not necessities

11248	Necessary truths can be two-way relational, where essential truths are one-way or intrinsic [Politis]
	Full Idea: An essence is true in virtue of what the thing is in itself, but a necessary truth may be relational, as the consequence of the relation between two things and their essence. The necessary relation may be two-way, but the essential relation one-way.
	From: Vassilis Politis (Aristotle and the Metaphysics [2004], 2.3)
	A reaction: He is writing about Aristotle, but has in mind Kit Fine 1994 (qv). Politis cites Plato's answer to the Euthyphro Question as a good example. The necessity comes from the intrinsic nature of goodness/piety, not from the desire of the gods.
