10. Modality / C. Sources of Modality / 1. Sources of Necessity

12432	Explanation of necessity must rest on something necessary or something contingent [Hale]
	Full Idea: The dilemma is that to give the ultimate source of any necessity, we must either appeal to something which could not have been otherwise (i.e. is itself necessary), or advert to something which could have been otherwise (i.e. is itself merely contingent).
	From: Bob Hale (The Source of Necessity [2002], p.301)
	A reaction: [Hale is summarising Blackburn's view, and going on to disagree with it] Hale looks for a third way, but Blackburn seems to face us with quite a plausible dilemma.

12434	Why is this necessary, and what is necessity in general; why is this necessary truth true, and why necessary? [Hale]
	Full Idea: We must distinguish between explaining particular necessities and explaining necessity in general; and we ought to distinguish between explaining, in regard to any necessary truth, why it is true, and explaining why it is necessary.
	From: Bob Hale (The Source of Necessity [2002], p.308)
	A reaction: Useful. The pluralist view I associate with Fine says we can explain types of necessity, but not necessity in general. If we seek truthmakers, there is a special case of what adds the necessity to the truth.

12435	The explanation of a necessity can be by a truth (which may only happen to be a necessary truth) [Hale]
	Full Idea: My claim is that there are non-transitive explanations of necessities, where what explains is indeed necessary, but what explains the necessity of the explanandum is not the explanation's necessity, but its truth simpliciter.
	From: Bob Hale (The Source of Necessity [2002], p.311)
	A reaction: The big idea is to avoid a regress of necessities. The actual truths he proposes are essentialist. An interesting proposal. It might depend on how one views essences (as giving identity, or causal power)

10. Modality / C. Sources of Modality / 3. Necessity by Convention

12433	If necessity rests on linguistic conventions, those are contingent, so there is no necessity [Hale]
	Full Idea: If the alleged necessity, e,g, 2+2=4, really does depend upon a convention governing the use of the words in which we state it, and the existence of that convention is merely a contingent matter, then it can't after all be necessary.
	From: Bob Hale (The Source of Necessity [2002], p.302)
	A reaction: [Hale is citing Blackburn for this claim] Hale suggests replies, by keeping truth and meaning separate, and involving laws of logic. Blackburn clearly has a good point.

10. Modality / C. Sources of Modality / 4. Necessity from Concepts

12436	Concept-identities explain how we know necessities, not why they are necessary [Hale]
	Full Idea: It seems to me that identity-relations among concepts have more to do with explaining how we know that vixens are female foxes etc., than with explaining why it is necessary, and, more generally, with explaining why some necessities are knowable a priori.
	From: Bob Hale (The Source of Necessity [2002], P.313)
	A reaction: Hale rejects the conceptual and conventional accounts of necessity, in favour of the essentialist view. This strikes me as a good suggestion of Hale's, since I agree with him about the essentialism.

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').

27. Natural Reality / D. Time / 1. Nature of Time / h. Presentism

22974	Presentists lack the materials for a realist view of change [Price,H]
	Full Idea: The presentist view seems to have lost the materials for a realist view of passage, change or temporal transition.
	From: Huw Price (The Flow of Time [2011], 2)
	A reaction: It is a nice point. How can a presentist talk of change if the only component that exists is the present time slice? Price says change can only be a kind of fiction for the presentist. Change in existence and in properties are distinct concepts.

27. Natural Reality / D. Time / 2. Passage of Time / d. Time series

22973	The present moment, time's direction, and time's dynamic quality seem to be objective facts [Price,H]
	Full Idea: The flow of time seems to be an objective feature of reality because of 1) the present moment can be objectively distinguished, 2) time has an objective direction, of earlier and later, and 3) there is something objectively dynamic about time.
	From: Huw Price (The Flow of Time [2011], 1.1)
	A reaction: Price sets out to undermine all three of these claims, in implicit defence of a psychological view. I disagree with him.

27. Natural Reality / D. Time / 2. Passage of Time / g. Time's arrow

22975	We must explain either the existence of a time direction, or our psychological sense of it [Price,H]
	Full Idea: If the world comes equipped with a time orientation, where does it come from? If it doesn't, what explains our psychological feeling of a direction for time?
	From: Huw Price (The Flow of Time [2011], 3.5)
	A reaction: The chances of 'explaining' either one look slim to me. That is, the fact would explain our experience, but the experience without the fact looks ridiculous, and I cannot conceive of any time-free entity which could explain the fact.
