6 ideas

1. Philosophy / D. Nature of Philosophy / 2. Invocation to Philosophy
Let us reason together, saith the Lord [Isaiah]
     Full Idea: Come now, and let us reason together, saith the Lord.
     From: Isaiah (23: Book of Isaiah [c.680 BCE], 01.18)
     A reaction: A verse which not only offers Biblical support for philosophy, but would also seem to be a challenge to Christian fideists.
5. Theory of Logic / E. Structures of Logic / 2. Logical Connectives / a. Logical connectives
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.
9. Objects / A. Existence of Objects / 5. Individuation / e. Individuation by kind
'Ultimate sortals' cannot explain ontological categories [Westerhoff on Wiggins]
     Full Idea: 'Ultimate sortals' are said to be non-subordinated, disjoint from one another, and uniquely paired with each object. Because of this, the ultimate sortal cannot be a satisfactory explication of the notion of an ontological category.
     From: comment on David Wiggins (Identity and Spatio-Temporal Continuity [1971], p.75) by Jan Westerhoff - Ontological Categories §26
     A reaction: My strong intuitions are that Wiggins is plain wrong, and Westerhoff gives the most promising reasons for my intuition. The simplest point is that objects can obviously belong to more than one category.
10. Modality / A. Necessity / 6. Logical Necessity
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.
27. Natural Reality / E. Cosmology / 1. Cosmology
The world is established, and cannot be moved [Isaiah]
     Full Idea: The world is also established, that it cannot be moved.
     From: Isaiah (23: Book of Isaiah [c.680 BCE], 93.1)
     A reaction: This verse caused big trouble for Galileo. The only reason I can think of for Isaiah to write this is that occasionally people were prone to panic, and worry that the Earth might suddenly and abruptly be moved.
28. God / A. Divine Nature / 1. God
Beside me there is no God [Isaiah]
     Full Idea: I am the first, and I am the last; and beside me there is no God.
     From: Isaiah (23: Book of Isaiah [c.680 BCE], 44.06)
     A reaction: This seems to be the first clear statement (c. 680 BCE) of monotheism, certainly preceding any Greek views on the subject (cf. Idea 2629,Idea 7347). It is not just an arrogant assertion by the jews, but a humble sacrifice, donating their god to humanity.
