12772 | Philosophy is a value- and attitude-driven enterprise [Fraassen] |
12771 | Is it likely that a successful, coherent, explanatory ontological hypothesis is true? [Fraassen] |
12773 | Analytic philosophy has an exceptional arsenal of critical tools [Fraassen] |
12770 | We may end up with a huge theory of carefully constructed falsehoods [Fraassen] |
13838 | A decent modern definition should always imply a semantics [Hacking] |
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] |
14919 | Empiricists deny what is unobservable, and reject objective modality [Fraassen] |
7447 | Probability was fully explained between 1654 and 1812 [Hacking] |
7448 | Probability is statistical (behaviour of chance devices) or epistemological (belief based on evidence) [Hacking] |
7449 | Epistemological probability based either on logical implications or coherent judgments [Hacking] |
6783 | To 'accept' a theory is not to believe it, but to believe it empirically adequate [Fraassen, by Bird] |
7450 | In the medieval view, only deduction counted as true evidence [Hacking] |
7451 | Formerly evidence came from people; the new idea was that things provided evidence [Hacking] |
3061 | Anaxarchus said that he was not even sure that he knew nothing [Anaxarchus, by Diog. Laertius] |
7452 | An experiment is a test, or an adventure, or a diagnosis, or a dissection [Hacking, by PG] |
14917 | To accept a scientific theory, we only need to believe that it is empirically adequate [Fraassen] |
7459 | Follow maths for necessary truths, and jurisprudence for contingent truths [Hacking] |
6784 | Why should the true explanation be one of the few we have actually thought of? [Fraassen, by Bird] |
12769 | Inference to best explanation contains all sorts of hidden values [Fraassen] |
13066 | An explanation is just descriptive information answering a particular question [Fraassen, by Salmon] |
12768 | We accept many scientific theories without endorsing them as true [Fraassen] |
