21238 | Later phenomenologists tried hard to incorporate social relationships [Bakewell] |
Full Idea: Ever since Husserl, phenomenologists and existentialists had been trying to stretch the definition of existence to incorporate our social lives and relationships. | |
From: Sarah Bakewell (At the Existentialist Café [2016], 08) | |
A reaction: I see a parallel move in Wittgenstein's Private Language Argument. Husserl's later work seems to have been along those lines. Putnam's Twin Earth too. |
21237 | Phenomenology begins from the immediate, rather than from axioms and theories [Bakewell] |
Full Idea: Traditional philosophy often started with abstract axioms or theories, but the German phenomenologists went straight for life as they experienced it, moment to moment. | |
From: Sarah Bakewell (At the Existentialist Café [2016], 01) | |
A reaction: Bakewell gives this as the gist of what Aron said to Sartre in 1933, providing the bridge from phenomenology to existentialism. The obvious thought is that everybody outside philosophy starts from immediate experience, so why is this philosophy? |
11984 | Asserting a possible property is to say it would have had the property if that world had been actual [Plantinga] |
Full Idea: To say than x has a property in a possible world is simply to say that x would have had the property if that world had been actual. | |
From: Alvin Plantinga (Transworld Identity or worldbound Individuals? [1973], I) | |
A reaction: Plantinga tries to defuse all the problems with identity across possible worlds, by hanging on to subjunctive verbs and modal modifiers. The point, though, was to explain these, or at least to try to give their logical form. |
11980 | A possible world is a maximal possible state of affairs [Plantinga] |
Full Idea: A possible world is just a maximal possible state of affairs. | |
From: Alvin Plantinga (Transworld Identity or worldbound Individuals? [1973], I) | |
A reaction: The key point here is that Plantinga includes the word 'possible' in his definition. Possibility defines the worlds, and so worlds cannot be used on their own to define possibility. |
11982 | If possible Socrates differs from actual Socrates, the Indiscernibility of Identicals says they are different [Plantinga] |
Full Idea: If the Socrates of the actual world has snubnosedness but Socrates-in-W does not, this is surely inconsistent with the Indiscernibility of Identicals, a principle than which none sounder can be conceived. | |
From: Alvin Plantinga (Transworld Identity or worldbound Individuals? [1973], I) | |
A reaction: However, we allow Socrates to differ over time while remaining the same Socrates, so some similar approach should apply here. In both cases we need some notion of what is essential to Socrates. But what unites aged 3 with aged 70? |
11983 | It doesn't matter that we can't identify the possible Socrates; we can't identify adults from baby photos [Plantinga] |
Full Idea: We may say it makes no sense to say that Socrates exists at a world, if there is in principle no way of identifying him. ...But this is confused. To suppose Agnew was a precocious baby, we needn't be able to pick him from a gallery of babies. | |
From: Alvin Plantinga (Transworld Identity or worldbound Individuals? [1973], I) | |
A reaction: This seems a good point, and yet we have a space-time line joining adult Agnew with baby Agnew, and no such causal link is available between persons in different possible worlds. What would be the criterion in each case? |
11985 | If individuals can only exist in one world, then they can never lack any of their properties [Plantinga] |
Full Idea: The Theory of Worldbound Individuals contends that no object exists in more than one possible world; this implies the outrageous view that - taking properties in the broadest sense - no object could have lacked any property that it in fact has. | |
From: Alvin Plantinga (Transworld Identity or worldbound Individuals? [1973], II) | |
A reaction: Leibniz is the best known exponent of this 'outrageous view', though Plantinga shows that Lewis may be seen in the same light, since only counterparts are found in possible worlds, not the real thing. The Theory does seem wrong. |
11986 | The counterparts of Socrates have self-identity, but only the actual Socrates has identity-with-Socrates [Plantinga] |
Full Idea: While Socrates has no counterparts that lack self-identity, he does have counterparts that lack identity-with-Socrates. He alone has that - the property, that is, of being identical with the object that in fact instantiates Socrateity. | |
From: Alvin Plantinga (Transworld Identity or worldbound Individuals? [1973], II) | |
A reaction: I am never persuaded by arguments which rest on such dubious pseudo-properties. Whether or not a counterpart of Socrates has any sort of identity with Socrates cannot be prejudged, as it would beg the question. |
11987 | Counterpart Theory absurdly says I would be someone else if things went differently [Plantinga] |
Full Idea: It makes no sense to say I could have been someone else, yet Counterpart Theory implies not merely that I could have been distinct from myself, but that I would have been distinct from myself had things gone differently in even the most miniscule detail. | |
From: Alvin Plantinga (Transworld Identity or worldbound Individuals? [1973], II) | |
A reaction: A counterpart doesn't appear to be 'me being distinct from myself'. We have to combine counterparts over possible worlds with perdurance over time. I am a 'worm' of time-slices. Anything not in that worm is not strictly me. |
17371 | Some kinds are very explanatory, but others less so, and some not at all [Devitt] |
Full Idea: Explanatory significance, hence naturalness, comes in degrees: positing some kinds may be very explanatory, positing others, only a little bit explanatory, positing others still, not explanatory at all. | |
From: Michael Devitt (Natural Kinds and Biological Realism [2009], 4) | |
A reaction: He mentions 'cousin' as a natural kind that is not very explanatory of anything. It interests us as humans, but not at all in other animals, it seems. ...Nice thought, though, that two squirrels might be cousins... |
17372 | The higher categories are not natural kinds, so the Linnaean hierarchy should be given up [Devitt] |
Full Idea: The signs are that the higher categories are not natural kinds and so the Linnaean hierarchy must be abandoned. ...This is not abandoning a hierarchy altogether, it is not abandoning a tree of life. | |
From: Michael Devitt (Natural Kinds and Biological Realism [2009], 6) | |
A reaction: Devitt's underlying point is that the higher and more general kinds do not have an essence (a specific nature), which is the qualification to be a natural kind. They explain nothing. Essence is the hallmark of natural kinds. Hmmm. |
17373 | Species pluralism says there are several good accounts of what a species is [Devitt] |
Full Idea: Species pluralism is the view that there are several equally good accounts of what it is to be a species. | |
From: Michael Devitt (Natural Kinds and Biological Realism [2009], 7) | |
A reaction: Devitt votes for it, and cites Dupré, among many other. Given the existence of rival accounts, all making good points, it is hard to resist this view. |
