5515 | Imaginary cases are good for revealing our beliefs, rather than the truth [Parfit] |
Full Idea: I believe it is worth considering imaginary cases (such as Teletransportation), as we can use them to discover, not what the truth is, but what we believe. | |
From: Derek Parfit (The Unimportance of Identity [1995], p.293) | |
A reaction: The trouble is that we might say that IF I were suddenly turned into a pig, then I would come to believe in dualism, but that will not and cannot happen, because dualism is false. It seems essential to accept the natural possibility of the case. |
5516 | Reduction can be by identity, or constitution, or elimination [Parfit, by PG] |
Full Idea: We can distinguish Identifying Reductionism (as in 'persons are bodies'), or Constitutive Reductionism (as in 'persons are distinct, but consist of thoughts etc.'), or Eliminative Reductionism (as in 'there are no persons, only thoughts etc.'). | |
From: report of Derek Parfit (The Unimportance of Identity [1995], p.295) by PG - Db (ideas) | |
A reaction: Constitutive Reductionism seems the most common one, as in 'chemistry just consists of lots of complicated physics'. He doesn't mention bridge laws, which are presumably only required in more complicated cases of constitutive reduction. |
21833 | Research suggest that we overrate conscious experience [Flanagan] |
Full Idea: The emerging consensus is that we probably overrate the power of conscious experience in our lives. Freud, of course, said the same thing for different reasons. | |
From: Owen Flanagan (The Really Hard Problem [2007], 3 'Ontology') | |
A reaction: [He cites Pockett, Banks and Gallagher 2006]. Freud was concerned with big deep secrets, but the modern view concerns ordinary decisions and perceptions. An important idea, which should incline us all to become Nietzscheans. |
5514 | Psychologists are interested in identity as a type of person, but philosophers study numerical identity [Parfit] |
Full Idea: When psychologists discuss identity, they are typically concerned with the kind of person someone is, or wants to be (as in an 'identity crisis'). But when philosophers discuss identity, it is numerical identity they mean. | |
From: Derek Parfit (The Unimportance of Identity [1995], p.293) | |
A reaction: I think it is important to note that the philosophical problem breaks down into two areas: whether I have numerical identity with myself over time, and whether other people have it. It may be that two different sets of criteria will emerge. |
5521 | If my brain-halves are transplanted into two bodies, I have continuity, and don't need identity [Parfit] |
Full Idea: If the two halves of my brain are transplanted into different bodies just like mine, they cannot both be me, since that would make them the same person. ..But my relation to these two contains everything that matters, so identity is not what matters. | |
From: Derek Parfit (The Unimportance of Identity [1995], p.314) | |
A reaction: I challenge his concept of what 'matters'. He has a rather solipsistic view of the problem, and I take Parfit to be a rather unsociable person, since his friends and partner will be keenly interested in the identities of the new beings. |
5522 | Over a period of time what matters is not that 'I' persist, but that I have psychological continuity [Parfit] |
Full Idea: We should revise our view about identity over time: what matters isn't that there will be someone alive who will be me; it is rather that there should be at least one living person who will be psychologically continuous with me as I am now. | |
From: Derek Parfit (The Unimportance of Identity [1995], p.316) | |
A reaction: Parfit and Locke seem to agree on this, and it is no accident that they both like 'science fiction' examples. Apparently Parfit wouldn't bat an eyelid if someone threatened to cut his corpus callosum. I rate it as a catastrophe for my current existence. |
5519 | It is fine to save two dying twins by merging parts of their bodies into one, and identity is irrelevant [Parfit] |
Full Idea: If I am largely paralysed, and my twin brother is dying of brain disease, then if the operation to graft my head onto his body is offered, I should accept the operation, and it is irrelevant whether this person would be me. | |
From: Derek Parfit (The Unimportance of Identity [1995], p.308) | |
A reaction: Parfit notes that the brain is a particularly significant part of the process. The fact that I might cheerfully accept this offer without philosophical worries doesn't get rid of the question 'who is this person?' Who should they remain married to? |
5520 | If two humans are merged surgically, the new identity is a purely verbal problem [Parfit] |
Full Idea: If there is someone with my head and my brother's body, it is a merely verbal question whether that person will be me, and that is why, even if it won't be me, that doesn't matter. ..What matters is not identity, but the facts of which identity consists. | |
From: Derek Parfit (The Unimportance of Identity [1995], p.310) | |
A reaction: It strikes me that from the subjective psychological point of view identity is of little interest, but from the objective external viewpoint (e.g. the forensic one) such questions are highly significant, and rightly so. |
5518 | It doesn't matter whether I exist with half my components replaced (any more than an audio system) [Parfit] |
Full Idea: It is quite uninteresting whether, with half its components replaced, I have the same audio system, and also whether I exist if half of my body were simultaneously replaced. | |
From: Derek Parfit (The Unimportance of Identity [1995], p.302) | |
A reaction: It is impossible to deny this, if the part replaced is not the brain. My doubt about Parfit's thesis is that while I may not care whether some modified thing is still me, my lawyers and the police might be very concerned. |
21834 | Sensations may be identical to brain events, but complex mental events don't seem to be [Flanagan] |
Full Idea: There is still some hope for something like identity theory for sensations. But almost no one believes that strict identity theory will work for more complex mental states. Strict identity is stronger than type neurophysicalism. | |
From: Owen Flanagan (The Really Hard Problem [2007], 3 'Ontology') | |
A reaction: It is so hard to express the problem. What needs to be explained? How can one bunch of neurons represent many different things? It's not like computing. That just transfers the data to brains, where the puzzling stuff happens. |
21837 | Morality is normative because it identifies best practices among the normal practices [Flanagan] |
Full Idea: Morality is 'normative' in the sense that it consists of the extraction of 'good' or 'excellent' practices from common practices. | |
From: Owen Flanagan (The Really Hard Problem [2007], 4 'Naturalism') | |
A reaction: I take normativity not be the mere labelling of certain things as 'good', but as a way of responding to that fact, with some sort of motivation. |
21830 | For Darwinians, altruism is either contracts or genetics [Flanagan] |
Full Idea: Two explanations came forward in the neo-Darwinian synthesis. Altruism is either 1) person-based reciprocal altruism, or 2) gene-based kin altruism. | |
From: Owen Flanagan (The Really Hard Problem [2007], 2 'Darwin') | |
A reaction: Flanagan obviously thinks there is also 'genuine psychological atruism'. Presumably we don't explain mathematics or music or the desire to travel as either contracts or genetics, so we have other explanations available. |
21835 | We need Eudaimonics - the empirical study of how we should flourish [Flanagan] |
Full Idea: It would be nice if I could advance the case for Eudaimonics - empirical enquiry into the nature, causes, and constituents of flourishing, …and the case for some ways of living and being as better than others. | |
From: Owen Flanagan (The Really Hard Problem [2007], 4 'Normative') | |
A reaction: Things seem to be moving in that direction. Lots of statistics about happiness have been appearing. |
21831 | Alienation is not finding what one wants, or being unable to achieve it [Flanagan] |
Full Idea: What Marx called 'alienation' is the widespread condition of not being able to discover what one wants, or not being remotely positioned to achieve. | |
From: Owen Flanagan (The Really Hard Problem [2007], 2 'Expanding') | |
A reaction: I took alienation to concern people's relationship to the means of production in their trade. On Flanagan's definition I would expect almost everyone aged under 20 to count as alienated. |
5990 | Theophrastus doubted whether nature could be explained teleologically [Theophrastus, by Gottschalk] |
Full Idea: Theophrastus questioned Aristotle's teaching on the extent to which teleological explanations could be applied to the natural world. | |
From: report of Theophrastus (On Metaphysics (frags) [c.320 BCE]) by H.B. Gottschalk - Aristotelianism | |
A reaction: It is interesting to see that Aristotle's own immediate successor had doubts about teleology. We usually assume that the ancients were teleological, and this was rejected in the seventeenth century (e.g. Idea 4826). |
21832 | Buddhists reject God and the self, and accept suffering as key, and liberation through wisdom [Flanagan] |
Full Idea: Buddhism rejected the idea of a creator God, and the unchanging self [atman]. They accept the appearance-reality distinction, reward for virtue [karma], suffering defining our predicament, and that liberation [nirvana] is possible through wisdom. | |
From: Owen Flanagan (The Really Hard Problem [2007], 3 'Buddhism') | |
A reaction: [Compressed] Flanagan is an analytic philosopher and a practising Buddhist. Looking at a happiness map today which shows Europeans largely happy, and Africans largely miserable, I can see why they thought suffering was basic. |
