4. Formal Logic / D. Modal Logic ML / 3. Modal Logic Systems / g. System S4
15102 S4 says there must be some necessary truths (the actual ones, of which there is at least one) [Cameron]
     Full Idea: S4 says there must be some necessary truths, because the actual necessary truths must be necessary. (It says if there are some actual necessary truths then that is so - but the S4 axiom is an actual necessary truth, if true).
     From: Ross P. Cameron (On the Source of Necessity [2010], 2)
5. Theory of Logic / G. Quantification / 4. Substitutional Quantification
10792 The substitutional quantifier is not in competition with the standard interpretation [Kripke, by Marcus (Barcan)]
     Full Idea: Kripke proposes that the substitutional quantifier is not a replacement for, or in competition with, the standard interpretation.
     From: report of Saul A. Kripke (A Problem about Substitutional Quantification? [1976]) by Ruth Barcan Marcus - Nominalism and Substitutional Quantifiers p.165
10. Modality / C. Sources of Modality / 1. Sources of Necessity
15103 Blackburn fails to show that the necessary cannot be grounded in the contingent [Cameron]
     Full Idea: I conclude that Blackburn has not shown that any grounding of the necessary in the contingent (the Contingency Horn of his dilemma) is doomed to failure.
     From: Ross P. Cameron (On the Source of Necessity [2010], 2)
     A reaction: [You must read the article for details of Cameron's argument!] He goes on to also reject the Necessity Horn (that there is a regress if necessities must rely on necessities).
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 / f. Eternalism
15104 The 'moving spotlight' theory makes one time privileged, while all times are on a par ontologically [Cameron]
     Full Idea: What seems so wrong about the 'moving spotlight' theory is that here one time is privileged, but all the times are on a par ontologically.
     From: Ross P. Cameron (On the Source of Necessity [2010], 4)
     A reaction: The whole thing is baffling, but this looks like a good point. All our intuitions make presentism (there's only the present) look like a better theory than the moving spotlight (that the present is just 'special').
