| 19053 | Logic would be more natural if negation only referred to predicates [Dummett] |
| Full Idea: A better proposal for a formal logic closer to natural language would be one that had a negation-operator only for (simple) predicates. | |
| From: Michael Dummett (Presupposition [1960], p.27) | |
| A reaction: Dummett observes that classical formal logic was never intended to be close to natural language. Term logic does have that aim, but the meta-question is whether that end is desirable, and why. |
| 19052 | Natural language 'not' doesn't apply to sentences [Dummett] |
| Full Idea: Natural language does not possess a sentential negation-operator. | |
| From: Michael Dummett (Presupposition [1960], p.27) | |
| A reaction: This is a criticism of Strawson, who criticises logic for not following natural language, but does it himself with negation. In the question of how language and logic connect, this idea seems important. Term Logic aims to get closer to natural language. |
| 3978 | Associations are held to connect Ideas together in the way the world is connected together [Fodor] |
| Full Idea: The laws of associations were held to explicate the semantic coherence of intentional processes, which adjust the causal relations among Ideas to reflect corresponding relations among the things that they're ideas of. | |
| From: Jerry A. Fodor (Jerry A. Fodor on himself [1994], p.296) | |
| A reaction: With the support of evolution, and the backing of a correspondence theory of truth, plus more sophistication in the associations, this might work. |
| 3976 | Intentional science needs objects with semantic and causal properties, and which obey laws [Fodor] |
| Full Idea: If there is to be an intentional science, there must be semantically evaluable things which have causal powers, and there must be laws relating beliefs and desires to one another, and to actions. | |
| From: Jerry A. Fodor (Jerry A. Fodor on himself [1994], p.293) | |
| A reaction: The semantics and causation sound fair enough, but the prospect of finding laws looks bleak (though, contrary to Davidson, I don't see why they can't exist). |
| 3980 | Intentional states and processes may be causal relations among mental symbols [Fodor] |
| Full Idea: It may be that intentional states are relations to mental symbols, and mental processes are implemented by causal relations among these symbols. | |
| From: Jerry A. Fodor (Jerry A. Fodor on himself [1994], p.296) | |
| A reaction: It is hard to see how something could have causal powers just by being a symbol. The theory needs something else to drive the causation. |
| 3981 | Most psychological properties seem to be multiply realisable [Fodor] |
| Full Idea: These days most philosophers of mind suppose that most psychological properties are multiply realisable. | |
| From: Jerry A. Fodor (Jerry A. Fodor on himself [1994], p.298) | |
| A reaction: This is just speculation. The physical part may seem very different, but turn out to be identical in the ways that matter (like a knife made of two different metals). |
| 3975 | Folk psychology explains behaviour by reference to intentional states like belief and desire [Fodor] |
| Full Idea: Folk psychology is primarily intentional explanation; it's the idea that people's behaviour can be explained by reference to the contents of their beliefs and desires. | |
| From: Jerry A. Fodor (Jerry A. Fodor on himself [1994], p.292) | |
| A reaction: Sounds good. To reject folk psychology (as reductivists tend to) is to reject the existence of significant intentional states which have causal properties |
| 3982 | How could the extrinsic properties of thoughts supervene on their intrinsic properties? [Fodor] |
| Full Idea: It is hard to see how the extrinsic properties of thoughts could supervene on their intrinsic properties. | |
| From: Jerry A. Fodor (Jerry A. Fodor on himself [1994], p.299) | |
| A reaction: This doesn't seem a big problem. Sometimes represented experiences establish the match; sometimes the match is not very good, or even wrong. |
| 1748 | Archelaus was the first person to say that the universe is boundless [Archelaus, by Diog. Laertius] |
| Full Idea: Archelaus was the first person to say that the universe is boundless. | |
| From: report of Archelaus (fragments/reports [c.450 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.Ar.3 |
| 3977 | Laws are true generalisations which support counterfactuals and are confirmed by instances [Fodor] |
| Full Idea: Laws are true generalisations that support counterfactuals and are confirmed by their instances. | |
| From: Jerry A. Fodor (Jerry A. Fodor on himself [1994], p.293) | |
| A reaction: This seems correct, but it doesn't disentangle laws as mental states from laws as features of nature |
| 5989 | Archelaus said life began in a primeval slime [Archelaus, by Schofield] |
| Full Idea: Archelaus wrote that life on Earth began in a primeval slime. | |
| From: report of Archelaus (fragments/reports [c.450 BCE]) by Malcolm Schofield - Archelaus | |
| A reaction: This sounds like a fairly clearcut assertion of the production of life by evolution. Darwin's contribution was to propose the mechanism for achieving it. We should honour the name of Archelaus for this idea. |
