7. Existence / A. Nature of Existence / 2. Types of Existence
19470 Thoughts in the 'third realm' cannot be sensed, and do not need an owner to exist [Frege]
7. Existence / C. Structure of Existence / 1. Grounding / a. Nature of grounding
17292 Avoid 'in virtue of' for grounding, since it might imply a reflexive relation such as identity [Audi,P]
17295 Ground relations depend on the properties [Audi,P]
17297 A ball's being spherical non-causally determines its power to roll [Audi,P]
17302 Ground is irreflexive, asymmetric, transitive, non-monotonic etc. [Audi,P]
17303 The best critique of grounding says it is actually either identity or elimination [Audi,P]
7. Existence / C. Structure of Existence / 1. Grounding / b. Relata of grounding
17294 Grounding is a singular relation between worldly facts [Audi,P]
17300 If grounding relates facts, properties must be included, as well as objects [Audi,P]
7. Existence / C. Structure of Existence / 1. Grounding / c. Grounding and explanation
17296 We must accept grounding, for our important explanations [Audi,P]
7. Existence / C. Structure of Existence / 1. Grounding / d. Grounding and reduction
17301 Reduction is just identity, so the two things are the same fact, so reduction isn't grounding [Audi,P]
7. Existence / D. Theories of Reality / 8. Facts / b. Types of fact
17293 Worldly facts are obtaining states of affairs, with constituents; conceptual facts also depend on concepts [Audi,P]
