4. Formal Logic / D. Modal Logic ML / 1. Modal Logic

10163

Propositional modal logic has been proved to be complete [Kripke, by Feferman/Feferman]

4. Formal Logic / D. Modal Logic ML / 3. Modal Logic Systems / a. Systems of modal logic

10760

With possible worlds, S4 and S5 are sound and complete, but S1-S3 are not even sound [Kripke, by Rossberg]

4. Formal Logic / D. Modal Logic ML / 7. Barcan Formula

16189

The variable domain approach to quantified modal logic invalidates the Barcan Formula [Kripke, by Simchen]

15132

The Barcan formulas fail in models with varying domains [Kripke, by Williamson]

6. Mathematics / A. Nature of Mathematics / 4. Using Numbers / c. Counting procedure

Parsons says counting is tagging as first, second, third..., and converting the last to a cardinal [Parsons,C, by Heck]

8. Modes of Existence / D. Universals / 1. Universals

8502	Realism doesn't explain 'a is F' any further by saying it is 'a has F-ness' [Devitt]

8. Modes of Existence / E. Nominalism / 1. Nominalism / b. Nominalism about universals

8503	The particular/universal distinction is unhelpful clutter; we should accept 'a is F' as basic [Devitt]

8. Modes of Existence / E. Nominalism / 1. Nominalism / c. Nominalism about abstracta

8501	Quineans take predication about objects as basic, not reference to properties they may have [Devitt]
