| 2468 | Type physicalism is a stronger claim than token physicalism [Fodor] |
| 2490 | Modern connectionism is just Hume's theory of the 'association' of 'ideas' [Fodor] |
| 2476 | The goal of thought is to understand the world, not instantly sort it into conceptual categories [Fodor] |
| 2499 | Modules analyse stimuli, they don't tell you what to do [Fodor] |

| 2497 | Something must take an overview of the modules [Fodor] |
| 2509 | Modules have in-built specialist information [Fodor] |

| 2473 | Analysis is impossible without the analytic/synthetic distinction [Fodor] |
