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.

8. Modes of Existence / B. Properties / 13. Tropes / a. Nature of tropes

18431	Internal relations combine some tropes into a nucleus, which bears the non-essential tropes [Simons, by Edwards]
	Full Idea: Simons's 'nuclear' option blends features of the substratum and bundle theories. First we have tropes collected by virtue of their internal relations, forming the essential kernel or nucleus. This nucleus then bears the non-essential tropes.
	From: report of Peter Simons (Particulars in Particular Clothing [1994], p.567) by Douglas Edwards - Properties 3.5
	A reaction: [compression of Edwards's summary] This strikes me as being a remarkably good theory. I am not sure of the ontological status of properties, such that they can (unaided) combine to make part of an object. What binds the non-essentials?

9. Objects / B. Unity of Objects / 1. Unifying an Object / a. Intrinsic unification

16650	'Unity' is a particularly difficult word, because things can have hidden unity [Duns Scotus]
	Full Idea: I believe that 'unity' is one of the more difficult words in philosophy, for there are in things many hidden (occultae) unities that are obscure to us.
	From: John Duns Scotus (Lectura [1298], I.17.2.4), quoted by Robert Pasnau - Metaphysical Themes 1274-1671
	A reaction: Some examples would be nice. Do the Earth and the Moon form a unity, because of gravity? How ponders whether whiteness and a white man are unified.

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.
