| 14401 | Every proposition is entirely about being [Lewis] |
| Full Idea: Every proposition, no matter what subject matter it may have, is entirely about being. | |
| From: David Lewis (Things qua Truthmakers [2003], p.26), quoted by Trenton Merricks - Truth and Ontology 4.VI | |
| A reaction: Since Lewis's propositions are sets of possible worlds, I presume this claim is made because proposition relates to all of the possible worlds, which therefore presumably embody Being. |
| 5992 | Chrysippus says action is the criterion for existence, which must be physical [Chrysippus, by Tieleman] |
| Full Idea: Chrysippus regarded power to act and be acted upon as the criterion for existence or being - a test satisfied by bodies alone. | |
| From: report of Chrysippus (fragments/reports [c.240 BCE]) by Teun L. Tieleman - Chrysippus | |
| A reaction: This defines existence in terms of causation. Is he ruling out a priori a particle (say) which exists, but never interacts with anything? If so, he is inclining towards anti-realism. |
