| 18365 | If truths are just identical with facts, then truths will make themselves true [David] |
| 18362 | Examples show that truth-making is just non-symmetric, not asymmetric [David] |
| 18360 | It is assumed that a proposition is necessarily true if its truth-maker exists [David] |
| 18358 | Two different propositions can have the same fact as truth-maker [David] |
| 18355 | What matters is truth-making (not truth-makers) [David] |
| 18354 | Correspondence is symmetric, while truth-making is taken to be asymmetric [David] |
| 18356 | Correspondence is an over-ambitious attempt to explain truth-making [David] |
| 18363 | Correspondence theorists see facts as the only truth-makers [David] |
| 18364 | Correspondence theory likes ideal languages, that reveal the structure of propositions [David] |
| 18357 | What makes a disjunction true is simpler than the disjunctive fact it names [David] |
| 18359 | One proposition can be made true by many different facts [David] |
| 10775 | The axiom of choice now seems acceptable and obvious (if it is meaningful) [Tharp] |
| 10766 | Logic is either for demonstration, or for characterizing structures [Tharp] |
| 10767 | Elementary logic is complete, but cannot capture mathematics [Tharp] |
| 10769 | Second-order logic isn't provable, but will express set-theory and classic problems [Tharp] |
| 10762 | In sentential logic there is a simple proof that all truth functions can be reduced to 'not' and 'and' [Tharp] |
| 10776 | The main quantifiers extend 'and' and 'or' to infinite domains [Tharp] |
| 10774 | There are at least five unorthodox quantifiers that could be used [Tharp] |
| 10777 | Skolem mistakenly inferred that Cantor's conceptions were illusory [Tharp] |
| 10773 | The Löwenheim-Skolem property is a limitation (e.g. can't say there are uncountably many reals) [Tharp] |
| 10765 | Soundness would seem to be an essential requirement of a proof procedure [Tharp] |
| 10763 | Completeness and compactness together give axiomatizability [Tharp] |
| 10770 | If completeness fails there is no algorithm to list the valid formulas [Tharp] |
| 10771 | Compactness is important for major theories which have infinitely many axioms [Tharp] |
| 10772 | Compactness blocks infinite expansion, and admits non-standard models [Tharp] |
| 10764 | A complete logic has an effective enumeration of the valid formulas [Tharp] |
| 10768 | Effective enumeration might be proved but not specified, so it won't guarantee knowledge [Tharp] |
| 18361 | A reflexive relation entails that the relation can't be asymmetric [David] |
| 7903 | The six perfections are giving, morality, patience, vigour, meditation, and wisdom [Nagarjuna] |
