| 17812 | Finite cardinalities don't need numbers as objects; numerical quantifiers will do [White,NP] |
| 17486 | Supervenience is simply modally robust property co-variance [Hendry] |
| 17481 | Nuclear charge (plus laws) explains electron structure and spectrum, but not vice versa [Hendry] |
| 1748 | Archelaus was the first person to say that the universe is boundless [Archelaus, by Diog. Laertius] |
