18877 | Moral realism doesn't seem to entail the existence of any things [Cameron] |
18868 | Surely if some propositions are grounded in existence, they all are? [Cameron] |
18867 | Orthodox Truthmaker applies to all propositions, and necessitates their truth [Cameron] |
18873 | God fixes all the truths of the world by fixing what exists [Cameron] |
18879 | What the proposition says may not be its truthmaker [Cameron] |
18880 | Rather than what exists, some claim that the truthmakers are ways of existence, dispositions, modalities etc [Cameron] |
18874 | Truthmaking doesn't require realism, because we can be anti-realist about truthmakers [Cameron] |
18869 | Without truthmakers, negative truths must be ungrounded [Cameron] |
18871 | I support the correspondence theory because I believe in truthmakers [Cameron] |
18870 | Maybe truthmaking and correspondence stand together, and are interdefinable [Cameron] |
17926 | Rejecting double negation elimination undermines reductio proofs [Colyvan] |
17925 | Showing a disproof is impossible is not a proof, so don't eliminate double negation [Colyvan] |
17924 | Excluded middle says P or not-P; bivalence says P is either true or false [Colyvan] |
17929 | Löwenheim proved his result for a first-order sentence, and Skolem generalised it [Colyvan] |
17930 | Axioms are 'categorical' if all of their models are isomorphic [Colyvan] |
17928 | Ordinal numbers represent order relations [Colyvan] |
17923 | Intuitionists only accept a few safe infinities [Colyvan] |
17941 | Infinitesimals were sometimes zero, and sometimes close to zero [Colyvan] |
17922 | Reducing real numbers to rationals suggested arithmetic as the foundation of maths [Colyvan] |
17936 | Transfinite induction moves from all cases, up to the limit ordinal [Colyvan] |
17940 | Most mathematical proofs are using set theory, but without saying so [Colyvan] |
17931 | Structuralism say only 'up to isomorphism' matters because that is all there is to it [Colyvan] |
17932 | If 'in re' structures relies on the world, does the world contain rich enough structures? [Colyvan] |
18875 | Realism says a discourse is true or false, and some of it is true [Cameron] |
18878 | Realism says truths rest on mind-independent reality; truthmaking theories are about which features [Cameron] |

17938 | Mathematics can show why some surprising events have to occur [Colyvan] |
17934 | Proof by cases (by 'exhaustion') is said to be unexplanatory [Colyvan] |
17933 | Reductio proofs do not seem to be very explanatory [Colyvan] |

19439 | God produces possibilities, and thus ideas [Leibniz] |
