11976 | Aristotelian essentialism says essences are not relative to specification [Lewis] |
Full Idea: So-called 'Aristotelian essentialism' is the doctrine of essences not relative to specifications. | |
From: David Lewis (Counterpart theory and Quant. Modal Logic [1968], III) | |
A reaction: In other words, they are so-called 'real essences', understood as de re. Quine says essences are all de dicto, and relative to some specification. I vote for Aristotle. |
11978 | Causal necessities hold in all worlds compatible with the laws of nature [Lewis] |
Full Idea: Just as a sentence is necessary if it holds in all worlds, so it is causally necessary if it holds in all worlds compatible with the laws of nature. | |
From: David Lewis (Counterpart theory and Quant. Modal Logic [1968], V) | |
A reaction: I don't believe in the so-called 'laws of nature', so I'm not buying that. Is there no distinction in Lewis's view between those sentences which must hold, and those which happen to hold universally? |
11979 | It doesn't take the whole of a possible Humphrey to win the election [Lewis] |
Full Idea: Even if Humphrey is a modal continuant, it doesn't take the whole of him to do such things as winning. | |
From: David Lewis (Counterpart theory and Quant. Modal Logic [1968], Post B) | |
A reaction: This responds to Kripke's famous example, that people only care about what happens to themselves, and not to some 'counterpart' of themselves. |
16994 | Counterpart theory is bizarre, as no one cares what happens to a mere counterpart [Kripke on Lewis] |
Full Idea: Probably Humphrey could not care less whether someone else, no matter how much resembling him, would have been victorious in another possible world. Thus Lewis's view seems even more bizarre that the usual transworld identification it replaces. | |
From: comment on David Lewis (Counterpart theory and Quant. Modal Logic [1968]) by Saul A. Kripke - Naming and Necessity notes and addenda note 13 | |
A reaction: I begin to see this as a devastating reply to a theory I previously found quite congenial. |
11974 | Counterparts are not the original thing, but resemble it more than other things do [Lewis] |
Full Idea: Your counterparts resemble you closely in content and context in important respects. They resemble you more closely than do the other things in their worlds. But they are not really you. | |
From: David Lewis (Counterpart theory and Quant. Modal Logic [1968], I) | |
A reaction: It is a dilemma. If my counterpart were exactly me, I couldn't contemplate possibly losing a leg, or my sanity. But if my counterpart isn't exactly me, then I don't have much interest in its fate. Only essences can save us here. Cf. me tomorrow. |
11975 | If the closest resembler to you is in fact quite unlike you, then you have no counterpart [Lewis] |
Full Idea: If whatever thing in world w6 it is that resembles you more closely than anything else in w6 is nevertheless quite unlike you; nothing in w6 resembles you at all closely. If so, you have no counterpart in w6. | |
From: David Lewis (Counterpart theory and Quant. Modal Logic [1968], I) | |
A reaction: This is the nub, because the whole theory rests on deciding whether two things resemble sufficiently 'closely'. But then we need a criterion of closeness, so we must start talking about which properties matter. Essences loom. |
11977 | Essential attributes are those shared with all the counterparts [Lewis] |
Full Idea: An essential attribute of something is an attribute it shares with all its counterparts. | |
From: David Lewis (Counterpart theory and Quant. Modal Logic [1968], III) | |
A reaction: I don't like this. It ties essence entirely to identity, but I think essence precedes identity. Essence is a nexus of causal and explanatory powers which bestows an identity on each thing. But essence might be unstable, and identity with it. |
17093 | Causation produces productive mechanisms; to understand the world, understand these mechanisms [Salmon] |
Full Idea: Causal processes, causal interactions, and causal laws provide the mechanisms by which the world works; to understand why certain things happen, we need to see how they are produced by these mechanisms. | |
From: Wesley Salmon (Scientific Explanation and the Causal Structure of the World [1984]), quoted by David-Hillel Ruben - Explaining Explanation Ch 7 | |
A reaction: I don't think I've ever found a better quotation on explanation. That strikes me as correct, and (basically) there is nothing more to be said. I'm not sure about the 'laws'. This is later Wesley Salmon. |
17492 | Salmon's interaction mechanisms needn't be regular, or involving any systems [Glennan on Salmon] |
Full Idea: While Salmon's mechanisms are processes involving interactions, the interactions are not necessarily regular, and they do not involve the operation of systems. | |
From: comment on Wesley Salmon (Scientific Explanation and the Causal Structure of the World [1984]) by Stuart Glennan - Mechanisms 'hierarchical' | |
A reaction: This is why modern mechanistic philosophy only began in 2000, despite Wesley Salmon's championing of the roughly mechanistic approach. |
12163 | Literary meaning emerges in comparisons, and tradition shows which comparisons are relevant [Scruton] |
Full Idea: We must discover the meanings that emerge when works of literature are experience in relation to each other. ...The importance of tradition is that it denotes - ideally, at least - the class of relevant comparisons. | |
From: Roger Scruton (Public Text and Common Reader [1982], p.27) | |
A reaction: This is a nice attempt to explain why we all agree that a thorough education in an art is an essential prerequisite for good taste. Some people (e.g. among the young) seem to have natural good taste. How does that happen? |
12162 | In literature, word replacement changes literary meaning [Scruton] |
Full Idea: In literary contexts semantically equivalent words cannot replace each other without loss of literary meaning. | |
From: Roger Scruton (Public Text and Common Reader [1982], p.25) | |
A reaction: The notion of 'literary meaning' is not a standard one, and is questionable whether 'meaning' is the right word, given that a shift in word in a poem is as much to do with sound as with connotations. |
12159 | Without intentions we can't perceive sculpture, but that is not the whole story [Scruton] |
Full Idea: A person for whom it made no difference whether a sculpture was carved by wind and rain or by human hand would be unable to interpret or perceive sculptures - even though the interpretation of sculpture is not the reading of an intention. | |
From: Roger Scruton (Public Text and Common Reader [1982], p.15) | |
A reaction: Scruton compares it to the role of intention in language, where there is objective meaning, even though intention is basic to speech. |
12160 | In aesthetic interest, even what is true is treated as though it were not [Scruton] |
Full Idea: In aesthetic interest, even what is true is treated as though it were not. | |
From: Roger Scruton (Public Text and Common Reader [1982], p.18) | |
A reaction: A nice aphorism. I always feel uncomfortable reading novels about real people, although the historical Macbeth doesn't bother me much. Novels are too close to reality. Macbeth didn't speak blank verse. |
12161 | We can be objective about conventions, but love of art is needed to understand its traditions [Scruton] |
Full Idea: An historian can elucidate convention while having no feeling for the art that exploits it; whereas an understanding of tradition is reserved for those with the critical insight which comes from the love of art, both past and present. | |
From: Roger Scruton (Public Text and Common Reader [1982], p.24) | |
A reaction: This aesthetic observation is obviously close to Scruton's well-known conservatism in politics. I am doubtful whether the notion of 'tradition' can stand up to close examination, though we all know roughly what he means. |
