18335 | There are five problems which the truth-maker theory might solve [Rami] |
18334 | The truth-maker idea is usually justified by its explanatory power, or intuitive appeal [Rami] |
18339 | The truth-making relation can be one-to-one, or many-to-many [Rami] |
18333 | Central idea: truths need truthmakers; and possibly all truths have them, and makers entail truths [Rami] |
18342 | Most theorists say that truth-makers necessitate their truths [Rami] |
18340 | It seems best to assume different kinds of truth-maker, such as objects, facts, tropes, or events [Rami] |
18341 | Truth-makers seem to be states of affairs (plus optional individuals), or individuals and properties [Rami] |
18346 | 'Truth supervenes on being' only gives necessary (not sufficient) conditions for contingent truths [Rami] |
18345 | 'Truth supervenes on being' avoids entities as truth-makers for negative truths [Rami] |
18343 | Maybe a truth-maker also works for the entailments of the given truth [Rami] |
18338 | Truth-making is usually internalist, but the correspondence theory is externalist [Rami] |
18337 | Correspondence theories assume that truth is a representation relation [Rami] |
18347 | Deflationist truth is an infinitely disjunctive property [Rami] |
13913 | The four 'perfect syllogisms' are called Barbara, Celarent, Darii and Ferio [Engelbretsen/Sayward] |
13914 | Syllogistic logic has one rule: what is affirmed/denied of wholes is affirmed/denied of their parts [Engelbretsen/Sayward] |
13915 | Syllogistic can't handle sentences with singular terms, or relational terms, or compound sentences [Engelbretsen/Sayward] |
13916 | Term logic uses expression letters and brackets, and '-' for negative terms, and '+' for compound terms [Engelbretsen/Sayward] |
18350 | Truth-maker theorists should probably reject the converse Barcan formula [Rami] |
9406 | A class is natural when everybody can spot further members of it [Quinton] |
13850 | In modern logic all formal validity can be characterised syntactically [Engelbretsen/Sayward] |
13849 | Classical logic rests on truth and models, where constructivist logic rests on defence and refutation [Engelbretsen/Sayward] |
13851 | Unlike most other signs, = cannot be eliminated [Engelbretsen/Sayward] |
13852 | Axioms are ω-incomplete if the instances are all derivable, but the universal quantification isn't [Engelbretsen/Sayward] |
15730 | Extreme nominalists say all classification is arbitrary convention [Quinton] |
18336 | Internal relations depend either on the existence of the relata, or on their properties [Rami] |
15728 | The naturalness of a class depends as much on the observers as on the objects [Quinton] |
9407 | Properties imply natural classes which can be picked out by everybody [Quinton] |
15729 | Uninstantiated properties must be defined using the instantiated ones [Quinton] |
8520 | An individual is a union of a group of qualities and a position [Quinton, by Campbell,K] |
10938 | The extremes of essentialism are that all properties are essential, or only very trivial ones [Rami] |
10940 | An 'individual essence' is possessed uniquely by a particular object [Rami] |
10939 | 'Sortal essentialism' says being a particular kind is what is essential [Rami] |
10934 | Unlosable properties are not the same as essential properties [Rami] |
10933 | Physical possibility is part of metaphysical possibility which is part of logical possibility [Rami] |
10932 | If it is possible 'for all I know' then it is 'epistemically possible' [Rami] |
