| 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] |
| 5750 | Consistency is modal, saying propositions are consistent if they could be true together [Melia] |
| 5737 | Predicate logic has connectives, quantifiers, variables, predicates, equality, names and brackets [Melia] |
| 15163 | The interest of quantified modal logic is its metaphysical necessity and essentialism [Soames] |
| 5744 | First-order predicate calculus is extensional logic, but quantified modal logic is intensional (hence dubious) [Melia] |
| 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] |
| 5740 | Second-order logic needs second-order variables and quantification into predicate position [Melia] |
| 15156 | The universal and existential quantifiers were chosen to suit mathematics [Soames] |
| 5741 | If every model that makes premises true also makes conclusion true, the argument is valid [Melia] |
| 5735 | Maybe names and predicates can capture any fact [Melia] |
| 5736 | No sort of plain language or levels of logic can express modal facts properly [Melia] |
| 13969 | Kripkean essential properties and relations are necessary, in all genuinely possible worlds [Soames] |
| 5746 | The Identity of Indiscernibles is contentious for qualities, and trivial for non-qualities [Melia] |
| 5738 | We may be sure that P is necessary, but is it necessarily necessary? [Melia] |
| 5732 | 'De re' modality is about things themselves, 'de dicto' modality is about propositions [Melia] |
| 15161 | There are more metaphysically than logically necessary truths [Soames] |
| 15162 | We understand metaphysical necessity intuitively, from ordinary life [Soames] |
| 5739 | Sometimes we want to specify in what ways a thing is possible [Melia] |
| 13973 | A key achievement of Kripke is showing that important modalities are not linguistic in source [Soames] |
| 5734 | Possible worlds make it possible to define necessity and counterfactuals without new primitives [Melia] |
| 5742 | In possible worlds semantics the modal operators are treated as quantifiers [Melia] |
| 5743 | If possible worlds semantics is not realist about possible worlds, logic becomes merely formal [Melia] |
| 5749 | Possible worlds could be real as mathematics, propositions, properties, or like books [Melia] |
| 13968 | Kripkean possible worlds are abstract maximal states in which the real world could have been [Soames] |
| 5751 | The truth of propositions at possible worlds are implied by the world, just as in books [Melia] |
| 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] |
| 5748 | We accept unverifiable propositions because of simplicity, utility, explanation and plausibility [Melia] |
| 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] |
| 18545 | The disinterested attitude of the judge is the hallmark of a judgement of beauty [Shaftesbury, by Scruton] |
| 6237 | Fear of God is not conscience, which is a natural feeling of offence at bad behaviour [Shaftesbury] |
| 6234 | If an irrational creature with kind feelings was suddenly given reason, its reason would approve of kind feelings [Shaftesbury] |
| 6233 | A person isn't good if only tying their hands prevents their mischief, so the affections decide a person's morality [Shaftesbury] |
| 6236 | People more obviously enjoy social pleasures than they do eating and drinking [Shaftesbury] |
| 6235 | Self-interest is not intrinsically good, but its absence is evil, as public good needs it [Shaftesbury] |
| 6232 | Every creature has a right and a wrong state which guide its actions, so there must be a natural end [Shaftesbury] |
| 5642 | For Shaftesbury, we must already have a conscience to be motivated to religious obedience [Shaftesbury, by Scruton] |
