18784 | In classical logic the connectives can be related elegantly, as in De Morgan's laws [Mares] |
18786 | Excluded middle standardly implies bivalence; attacks use non-contradiction, De M 3, or double negation [Mares] |
18780 | Standard disjunction and negation force us to accept the principle of bivalence [Mares] |
18782 | The connectives are studied either through model theory or through proof theory [Mares] |
18783 | Many-valued logics lack a natural deduction system [Mares] |
18792 | Situation semantics for logics: not possible worlds, but information in situations [Mares] |
18785 | Consistency is semantic, but non-contradiction is syntactic [Mares] |
18788 | For intuitionists there are not numbers and sets, but processes of counting and collecting [Mares] |
15554 | A disposition needs a causal basis, a property in a certain causal role. Could the disposition be the property? [Lewis] |
15560 | We can explain a chance event, but can never show why some other outcome did not occur [Lewis] |
15559 | Does a good explanation produce understanding? That claim is just empty [Lewis] |
15556 | Science may well pursue generalised explanation, rather than laws [Lewis] |
15558 | A good explanation is supposed to show that the event had to happen [Lewis] |
4809 | Lewis endorses the thesis that all explanation of singular events is causal explanation [Lewis, by Psillos] |
14321 | To explain an event is to provide some information about its causal history [Lewis] |
18791 | In 'situation semantics' our main concepts are abstracted from situations [Mares] |
22489 | 'Good' is an attributive adjective like 'large', not predicative like 'red' [Geach, by Foot] |
