13966 | Analytic philosophy loved the necessary a priori analytic, linguistic modality, and rigour [Soames] |
13974 | If philosophy is analysis of meaning, available to all competent speakers, what's left for philosophers? [Soames] |
15163 | The interest of quantified modal logic is its metaphysical necessity and essentialism [Soames] |
11022 | Gentzen introduced a natural deduction calculus (NK) in 1934 [Gentzen, by Read] |
11065 | The inferential role of a logical constant constitutes its meaning [Gentzen, by Hanna] |
11023 | The logical connectives are 'defined' by their introduction rules [Gentzen] |
11213 | Each logical symbol has an 'introduction' rule to define it, and hence an 'elimination' rule [Gentzen] |
15158 | Indefinite descriptions are quantificational in subject position, but not in predicate position [Soames] |
15157 | Recognising the definite description 'the man' as a quantifier phrase, not a singular term, is a real insight [Soames] |
15156 | The universal and existential quantifiers were chosen to suit mathematics [Soames] |
13832 | Natural deduction shows the heart of reasoning (and sequent calculus is just a tool) [Gentzen, by Hacking] |
10067 | Gentzen proved the consistency of arithmetic from assumptions beyond arithmetic [Gentzen, by Musgrave] |
13969 | Kripkean essential properties and relations are necessary, in all genuinely possible worlds [Soames] |
15162 | We understand metaphysical necessity intuitively, from ordinary life [Soames] |
15161 | There are more metaphysically than logically necessary truths [Soames] |
13973 | A key achievement of Kripke is showing that important modalities are not linguistic in source [Soames] |
13968 | Kripkean possible worlds are abstract maximal states in which the real world could have been [Soames] |
20653 | Six reduction levels: groups, lives, cells, molecules, atoms, particles [Putnam/Oppenheim, by Watson] |
15152 | To study meaning, study truth conditions, on the basis of syntax, and representation by the parts [Soames] |
15153 | Tarski's account of truth-conditions is too weak to determine meanings [Soames] |
13965 | Semantics as theory of meaning and semantics as truth-based logical consequence are very different [Soames] |
13964 | Semantic content is a proposition made of sentence constituents (not some set of circumstances) [Soames] |
13972 | Two-dimensionalism reinstates descriptivism, and reconnects necessity and apriority to analyticity [Soames] |
15154 | We should use cognitive states to explain representational propositions, not vice versa [Soames] |
