18880 | Rather than what exists, some claim that the truthmakers are ways of existence, dispositions, modalities etc [Cameron] |
18874 | Truthmaking doesn't require realism, because we can be anti-realist about truthmakers [Cameron] |
18932 | The facts about the existence of truthmakers can't have a further explanation [Cameron] |
15394 | Truthmaker requires a commitment to tropes or states of affairs, for contingent truths [Cameron] |

7798 | There are three axiom schemas for propositional logic [Girle] |
7786 | Propositional logic handles negation, disjunction, conjunction; predicate logic adds quantifiers, predicates, relations [Girle] |
7799 | Proposition logic has definitions for its three operators: or, and, and identical [Girle] |

7794 | There are seven modalities in S4, each with its negation [Girle] |
15102 | S4 says there must be some necessary truths (the actual ones, of which there is at least one) [Cameron] |
