13838 | A decent modern definition should always imply a semantics [Hacking] |
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] |
18870 | Maybe truthmaking and correspondence stand together, and are interdefinable [Cameron] |
18871 | I support the correspondence theory because I believe in truthmakers [Cameron] |
13833 | 'Thinning' ('dilution') is the key difference between deduction (which allows it) and induction [Hacking] |
13834 | Gentzen's Cut Rule (or transitivity of deduction) is 'If A |- B and B |- C, then A |- C' [Hacking] |
13835 | Only Cut reduces complexity, so logic is constructive without it, and it can be dispensed with [Hacking] |
13845 | The various logics are abstractions made from terms like 'if...then' in English [Hacking] |
13840 | First-order logic is the strongest complete compact theory with Löwenheim-Skolem [Hacking] |
13844 | A limitation of first-order logic is that it cannot handle branching quantifiers [Hacking] |
13842 | Second-order completeness seems to need intensional entities and possible worlds [Hacking] |
13837 | With a pure notion of truth and consequence, the meanings of connectives are fixed syntactically [Hacking] |
13839 | Perhaps variables could be dispensed with, by arrows joining places in the scope of quantifiers [Hacking] |
13843 | If it is a logic, the Löwenheim-Skolem theorem holds for it [Hacking] |
18881 | For realists it is analytic that truths are grounded in the world [Cameron] |
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] |
14534 | Shoemaker moved from properties as powers to properties bestowing powers [Shoemaker, by Mumford/Anjum] |
18872 | We should reject distinct but indiscernible worlds [Cameron] |
