8945 | Fuzzy logic has many truth values, ranging in fractions from 0 to 1 [Fisher] |
8951 | Classical logic is: excluded middle, non-contradiction, contradictions imply all, disjunctive syllogism [Fisher] |
8950 | Logic formalizes how we should reason, but it shouldn't determine whether we are realists [Fisher] |
21539 | Excluded middle can be stated psychologically, as denial of p implies assertion of not-p [Russell] |
7755 | Singular terms refer, using proper names, definite descriptions, singular personal pronouns, demonstratives, etc. [Lycan] |
21538 | If two people perceive the same object, the object of perception can't be in the mind [Russell] |
8946 | We could make our intuitions about heaps precise with a million-valued logic [Fisher] |
21534 | The only thing we can say about relations is that they relate [Russell] |
21540 | Relational propositions seem to be 'about' their terms, rather than about the relation [Russell] |
21536 | When I perceive a melody, I do not perceive the notes as existing [Russell] |
21535 | Objects only exist if they 'occupy' space and time [Russell] |
8944 | Vagueness can involve components (like baldness), or not (like boredom) [Fisher] |
8941 | We can't explain 'possibility' in terms of 'possible' worlds [Fisher] |
21533 | Contingency arises from tensed verbs changing the propositions to which they refer [Russell] |
8947 | If all truths are implied by a falsehood, then not-p might imply both q and not-q [Fisher] |
8949 | In relevance logic, conditionals help information to flow from antecedent to consequent [Fisher] |
21537 | I assume we perceive the actual objects, and not their 'presentations' [Russell] |
21532 | Full empiricism is not tenable, but empirical investigation is always essential [Russell] |
21542 | Do incorrect judgements have non-existent, or mental, or external objects? [Russell] |
21541 | The complexity of the content correlates with the complexity of the object [Russell] |
7768 | The truth conditions theory sees meaning as representation [Lycan] |
7766 | Meaning must be known before we can consider verification [Lycan] |
7764 | Could I successfully use an expression, without actually understanding it? [Lycan] |
7763 | It is hard to state a rule of use for a proper name [Lycan] |
7770 | Truth conditions will come out the same for sentences with 'renate' or 'cordate' [Lycan] |
7773 | A sentence's truth conditions is the set of possible worlds in which the sentence is true [Lycan] |
7774 | Possible worlds explain aspects of meaning neatly - entailment, for example, is the subset relation [Lycan] |
21543 | If p is false, then believing not-p is knowing a truth, so negative propositions must exist [Russell] |
