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]

9. Objects / E. Objects over Time / 6. Successive Things

16700

In order to speak about time and successive entities, the 'present' must be enlarged [Wycliff]

16701

To be successive a thing needs parts, which must therefore be lodged outside that instant [Wycliff]

26. Natural Theory / C. Causation / 4. Naturalised causation

8412	A causal interaction is when two processes intersect, and correlated modifications persist afterwards [Salmon]

26. Natural Theory / C. Causation / 5. Direction of causation

8413	Cause must come first in propagations of causal interactions, but interactions are simultaneous [Salmon]

26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata

8411	Instead of localised events, I take enduring and extended processes as basic to causation [Salmon]
