17597 | Coherence is explanatory, deductive, conceptual, analogical, perceptual, and deliberative [Thagard] |
17598 | Explanatory coherence needs symmetry,explanation,analogy,data priority, contradiction,competition,acceptance [Thagard] |
17602 | Verisimilitude comes from including more phenomena, and revealing what underlies [Thagard] |
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] |
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] |
16978 | If conceivability is a priori coherence, that implies possibility [Tahko] |
17601 | Neither a priori rationalism nor sense data empiricism account for scientific knowledge [Thagard] |
17600 | Bayesian inference is forced to rely on approximations [Thagard] |
17066 | 3: If an analogous pair explain another analogous pair, then they all cohere [Thagard, by Smart] |
17064 | 1: Coherence is a symmetrical relation between two propositions [Thagard, by Smart] |
17067 | 4: For coherence, observation reports have a degree of intrinsic acceptability [Thagard, by Smart] |
17068 | 5: Contradictory propositions incohere [Thagard, by Smart] |
17069 | 6: A proposition's acceptability depends on its coherence with a system [Thagard, by Smart] |
17065 | 2: An explanation must wholly cohere internally, and with the new fact [Thagard, by Smart] |
16975 | Essences are used to explain natural kinds, modality, and causal powers [Tahko] |
17599 | The best theory has the highest subjective (Bayesian) probability? [Thagard] |
16976 | Scientific essentialists tend to characterise essence in terms of modality (not vice versa) [Tahko] |
16977 | If essence is modal and laws are necessary, essentialist knowledge is found by scientists [Tahko] |
