Logic | II 47ff Bivalence: Problem: Sorites. --- II 53 Bivalence is still a basic feature of our scientific world. - In the liberal sense there is no problem - Frege: each general term is true or not - all terms are vague by ostension. --- II 168 Logic, old: deals with properties - new: with relations - Quine: feels implications. --- II 169 Logic, old: failed with relative terms: drawing figures/drawing circles (Carroll) - new: no problem with that: implication lies precisely in the relative term. --- II 173 Existence: "all x are y" controversy: does this imply the existence of "x"? medieval logic: yes - Modern Times: No (thus gains in symmetry and simplicity). --- VII 82 Logic/Quine: triple: propositions - classes - relations - logical terms: we only need three "e" ("element of") - Sheffer stroke and universal quantifier. --- VII 82 Logic/Quine: triple: propositions - classes - relations - logical terms: we only need three "e" ("element of") - Sheffer stroke and universal quantifier. --- VII 119 ff Class logic/Quine: emerges from quantifier logic if we bind scheme letters (predicate letters) "F" etc. - ((s) 2nd order Logic ). --- IX 8 Logic/Quine: main task: to prove the validity of schemes - 2nd order logic: this is about the validity of the formula schemes of quantifier logic - E.g. substitutability of bi-subjunction: "x1 ..." xn[((AB) and CA)> CB]. --- X 110 Logic/Quine: if you determine the totality of logical truths, you have established the logic. --- X 110 Different logic/Quine: no differing procedure of taking evidence, but rejection of part of the logic as untrue. --- X 111 "Everything could be different"/translation/different logic/interchanging/and/or/key position/ Gavagai/Quine: assuming a heterodox logic, in which the laws of the adjunction now apply to the conjunction, and vice versa - mere change of phonetics or the designation. - ((s) If he says adjunction, he uses our conjunction.) - Quine: we force our logic on him by translating his different way of expressing himself. - It is pointless to ask which one is the right conjunction. - There is also no essence of the conjunction beyond the sounds and signs and the laws for its use. |
