| 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. |
| 19520 | Evidentialism is not axiomatic; the evidence itself inclines us towards evidentialism [Conee] |
| Full Idea: Evidentialism does not support beginning epistemology by taking for granted that evidentialism is true. ...Rather, what potentially justifies belief in intial epistemic data and initial procedures of inquiry is the evidence itself. | |
| From: Earl Conee (First Things First [2004], 'Getting') | |
| A reaction: This sounds good. I much prefer talk of 'evidence' to talk of 'perceptions', because evidence has been licked into shape, and its significance has been clarified. That is the first step towards the coherence we seek. |
| 19521 | If pure guesses were reliable, reliabilists would have to endorse them [Conee] |
| Full Idea: Reliabilism would count pure guesses as good reasons if guessing were properly reliable. | |
| From: Earl Conee (First Things First [2004], 'Getting') | |
| A reaction: See D.H. Lawrence's short story 'The Rocking Horse Winner'. This objection strikes me as being so devastating that it is almost conclusive. Except that pure guesses are never ever reliable, over a decent period of time. |
| 19522 | More than actual reliability is needed, since I may mistakenly doubt what is reliable [Conee] |
| Full Idea: Sheer reliability does not justify belief. ...It may be, for instance, that we have strong though misleading reason to deny the method's reliability. | |
| From: Earl Conee (First Things First [2004], 'Circles') | |
| A reaction: That is, we accept a justification if we judge the method to be reliable, not if it IS reliable. I can disbelieve all the reliable information that arrives in my mind. People do that all the time! Hatred of experts! Support for internalism? |
| 19523 | Reliabilism is poor on reflective judgements about hypothetical cases [Conee] |
| Full Idea: An unrefined reliability theory does a poor job at capturing reflective judgements about hypothetical cases | |
| From: Earl Conee (First Things First [2004], 'Stroud's') | |
| A reaction: Reliability can only be a test for tried and tested ways. No one can say whether imagining a range of possibilities is reliable or not. Is prediction a reliable route to knowledge? |
| 8070 | It would be better to point to failings of character, than to moral wrongness of actions [Anscombe] |
| Full Idea: It would be a great improvement if, instead of 'morally wrong', one always named a genus such as 'untruthful', 'unchaste', or 'unjust'. | |
| From: G.E.M. Anscombe (Modern Moral Philosophy [1958], p.183) | |
| A reaction: People are indeed much more struck by the suggestion that they have a weakness of character, rather than that they have just done something wrong. This is Anscombe's first great appeal for a return to virtue as the basis of ethics. |
| 8065 | 'Ought' and 'right' are survivals from earlier ethics, and should be jettisoned [Anscombe] |
| Full Idea: The moral sense of 'ought' and of what is right should be jettisoned, if possible, because they are survivals from an earlier conception of ethics, and are only harmful without it. | |
| From: G.E.M. Anscombe (Modern Moral Philosophy [1958], p.175) | |
| A reaction: This is part of a revolutionary proposal to return to virtue theory, and has had a great influence (e.g. on me). Richard Taylor gives a good account of how duty lost its social and religious underpinnings. Our duties now seem to be purely contractual. |
| 8069 | Between Aristotle and us, a Judaeo-Christian legal conception of ethics was developed [Anscombe] |
| Full Idea: Between Aristotle and us came Christianity, with its law conception of ethics, and Christianity derived its ethical notions from the Torah. | |
| From: G.E.M. Anscombe (Modern Moral Philosophy [1958], p.179) | |
| A reaction: While I am a fan of the primacy of the virtues in ethical thinking, I am doubtful about the complete elimination of laws (e.g. by Particularists). The law teaches us the virtues, and reminds us of them (like speed-limit signs). |
