5. Theory of Logic / E. Structures of Logic / 2. Logical Connectives / a. Logical connectives

16974	The nature of each logical concept is given by a collection of inference rules [Correia]
	Full Idea: The view presented here presupposes that each logical concept is associated with some fixed and well defined collection of rules of inference which characterize its basic logical nature.
	From: Fabrice Correia (On the Reduction of Necessity to Essence [2012], 4)
	A reaction: [He gives Fine's 'Senses of Essences' 57-8 as a source] He seems to have in mind natural deduction, where the rules are for the introduction and elimination of the concepts.

10. Modality / A. Necessity / 6. Logical Necessity

16973	Explain logical necessity by logical consequence, or the other way around? [Correia]
	Full Idea: One view is that logical consequence is to be understood in terms of logical necessity (some proposition holds necessarily, if some group of other propositions holds). Alternatively, logical necessity is a logical consequence of the empty set.
	From: Fabrice Correia (On the Reduction of Necessity to Essence [2012], 3)
	A reaction: I think my Finean preference is for all necessities to have a 'necessitator', so logical necessity results from logic in some way, perhaps from logical consequence, or from the essences of the connectives and operators.

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').

26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / g. Atomism

20919	How can things without weight compose weight? [Alexander]
	Full Idea: How could weight come about out of things composed of what is without weight?
	From: Alexander (On Aristotle's Metaphysics Book 2 [c.200], p.36.21-27)
	A reaction: This is obviously why Epicurus added weight to the features of atoms. Alexander seems unaware of this move.
