21566 | 'Propositional functions' are ambiguous until the variable is given a value [Russell] |
21567 | 'All judgements made by Epimenedes are true' needs the judgements to be of the same type [Russell] |
23457 | Type theory cannot identify features across levels (because such predicates break the rules) [Morris,M on Russell] |
21556 | Classes are defined by propositional functions, and functions are typed, with an axiom of reducibility [Russell, by Lackey] |

3863 | The anomaly of Uranus didn't destroy Newton's mechanics - it led to Neptune's discovery [Newton-Smith] |
3864 | Anomalies are judged against rival theories, and support for the current theory [Newton-Smith] |
3865 | Why should it matter whether or not a theory is scientific? [Newton-Smith] |
3866 | If theories are really incommensurable, we could believe them all [Newton-Smith] |
