| 14627 | S4, and therefore S5, are invalid for metaphysical modality [Salmon,N, by Williamson] |
| 17486 | Supervenience is simply modally robust property co-variance [Hendry] |
| 18888 | Essentialism says some properties must be possessed, if a thing is to exist [Salmon,N] |
| 1556 | By nature people are close to one another, but culture drives them apart [Hippias] |
| 17481 | Nuclear charge (plus laws) explains electron structure and spectrum, but not vice versa [Hendry] |
| 18886 | Frege's 'sense' solves four tricky puzzles [Salmon,N] |
| 18887 | The perfect case of direct reference is a variable which has been assigned a value [Salmon,N] |
| 17478 | Maybe two kinds are the same if there is no change of entropy on isothermal mixing [Hendry] |
| 18891 | Nothing in the direct theory of reference blocks anti-essentialism; water structure might have been different [Salmon,N] |

| 17484 | Maybe the nature of water is macroscopic, and not in the microstructure [Hendry] |
| 17485 | Maybe water is the smallest part of it that still counts as water (which is H2O molecules) [Hendry] |
| 17483 | Water continuously changes, with new groupings of molecules [Hendry] |
| 17482 | Compounds can differ with the same collection of atoms, so structure matters too [Hendry] |
| 17476 | Elements survive chemical change, and are tracked to explain direction and properties [Hendry] |
| 17477 | Defining elements by atomic number allowed atoms of an element to have different masses [Hendry] |
| 17480 | Generally it is nuclear charge (not nuclear mass) which determines behaviour [Hendry] |
