10890 | A 'partial ordering' is reflexive, antisymmetric and transitive [Zalabardo] |
10886 | Determinacy: an object is either in a set, or it isn't [Zalabardo] |
10887 | Specification: Determinate totals of objects always make a set [Zalabardo] |
10897 | A first-order 'sentence' is a formula with no free variables [Zalabardo] |
10893 | Γ |= φ for sentences if φ is true when all of Γ is true [Zalabardo] |

10896 | Propositional logic just needs ¬, and one of ∧, ∨ and → [Zalabardo] |
10898 | The semantics shows how truth values depend on instantiations of properties and relations [Zalabardo] |
10902 | We can do semantics by looking at given propositions, or by building new ones [Zalabardo] |
10892 | We make a truth assignment to T and F, which may be true and false, but merely differ from one another [Zalabardo] |
10895 | 'Logically true' (|= φ) is true for every truth-assignment [Zalabardo] |
10900 | Logically true sentences are true in all structures [Zalabardo] |
10901 | Some formulas are 'satisfiable' if there is a structure and interpretation that makes them true [Zalabardo] |
10894 | A sentence-set is 'satisfiable' if at least one truth-assignment makes them all true [Zalabardo] |
10903 | A structure models a sentence if it is true in the model, and a set of sentences if they are all true in the model [Zalabardo] |
10891 | If a set is defined by induction, then proof by induction can be applied to it [Zalabardo] |
16062 | A necessary relation between fact-levels seems to be a further irreducible fact [Lynch/Glasgow] |
16061 | If some facts 'logically supervene' on some others, they just redescribe them, adding nothing [Lynch/Glasgow] |
16060 | Nonreductive materialism says upper 'levels' depend on lower, but don't 'reduce' [Lynch/Glasgow] |
16064 | The hallmark of physicalism is that each causal power has a base causal power under it [Lynch/Glasgow] |
18422 | Prioprioception focuses on your body parts, not on your self, or indexicality [Cappelen/Dever] |
18425 | We can acquire self-knowledge with mirrors, not just with proprioception and introspection [Cappelen/Dever] |
18421 | Proprioception is only immune from error if you are certain that it represents the agent [Cappelen/Dever] |

18407 | Indexicality is not significantly connected to agency [Cappelen/Dever] |
18427 | If some of our thought is tied to its context, it will be hard to communicate it [Cappelen/Dever] |

18413 | Fregeans can't agree on what 'senses' are [Cappelen/Dever] |
18417 | Possible worlds accounts of content are notoriously coarse-grained [Cappelen/Dever] |
18408 | Indexicals are just non-constant in meaning, and don't involve any special concepts [Cappelen/Dever] |
18414 | Fregeans say 'I' differs in reference, so it must also differ in sense [Cappelen/Dever] |
18423 | All indexicals can be expressed non-indexically [Cappelen/Dever] |
18406 | The basic Kaplan view is that there is truth-conditional content, and contextual character [Cappelen/Dever] |

18420 | We deny that action involves some special class of beliefs [Cappelen/Dever] |
