| 9193 | ZF set theory has variables which range over sets, 'equals' and 'member', and extensionality [Dummett] |
| 9194 | The main alternative to ZF is one which includes looser classes as well as sets [Dummett] |
| 9195 | Intuitionists reject excluded middle, not for a third value, but for possibility of proof [Dummett] |
| 9186 | First-order logic concerns objects; second-order adds properties, kinds, relations and functions [Dummett] |
| 9187 | Logical truths and inference are characterized either syntactically or semantically [Dummett] |
| 9191 | Ordinals seem more basic than cardinals, since we count objects in sequence [Dummett] |
| 9192 | The number 4 has different positions in the naturals and the wholes, with the same structure [Dummett] |

| 2591 | Total paralysis would mean that there were mental states but no behaviour at all [Putnam] |
| 2588 | Is pain a functional state of a complete organism? [Putnam] |
| 2589 | Functionalism is compatible with dualism, as pure mind could perform the functions [Putnam] |
| 2592 | Functional states correlate with AND explain pain behaviour [Putnam] |
