14961 | Clearly a pipe can survive being taken apart [Cartwright,R] |
Full Idea: There is at the moment a pipe on my desk. Its stem has been removed but it remains a pipe for all that; otherwise no pipe could survive a thorough cleaning. | |
From: Richard Cartwright (Scattered Objects [1974], p.175) | |
A reaction: To say that the pipe survives dismantling is not to say that it is fully a pipe during its dismantled phase. He gives a further example of a book in two volumes. |
14962 | Bodies don't becomes scattered by losing small or minor parts [Cartwright,R] |
Full Idea: If a branch falls from a tree, the tree does not thereby become scattered, and a human body does not become scattered upon loss of a bit of fingernail. | |
From: Richard Cartwright (Scattered Objects [1974], p.184) | |
A reaction: This sort of observation draws me towards essentialism. A body is scattered if you divide it in a major way, but not if you separate off a minor part. It isn't just a matter of size, or even function. We have broader idea of what is essential. |
2957 | Brain bisection suggests unity of mind isn't all-or-nothing [Nagel, by Lockwood] |
Full Idea: Nagel argues (because of brain bisection experiments) that we should jettison our commonsense assumption that the unity of consciousness is an all-or-nothing affair. | |
From: report of Thomas Nagel (Brain Bisection and Unity of Consciousness [1971]) by Michael Lockwood - Mind, Brain and the Quantum p.84 | |
A reaction: It seems wrong to call it 'commonsense'. It is an assumption that precedes any judgement, but if you rapidly grasp that your mind is in your brain, it becomes common sense that you can cut lumps out of your mind. |
3285 | We may be unable to abandon personal identity, even when split-brains have undermined it [Nagel] |
Full Idea: As a result of the evidence of split-brains, it is possible that the ordinary, simple idea of a single person will come to seem quaint some day, …but we may be unable to abandon the idea, no matter what we discover. | |
From: Thomas Nagel (Brain Bisection and Unity of Consciousness [1971], p.164) | |
A reaction: I'm not sure what grounds you can have for a claim that we can't abandon our current view of selves, even when the new reality will be utterly different. Rather conservative? I would expect future concepts to roughly match future reality. |
3519 | Man uses his body, so must be separate from it [Anon (Plat), by Maslin] |
Full Idea: A man uses his whole body to do things, and therefore, just as a person is distinct from a tool he uses, so it follows that a man must be distinct from his body. | |
From: report of Anon (Plat) (Alcibiades [c.340 BCE]) by Keith T. Maslin - Introduction to the Philosophy of Mind 2.3 | |
A reaction: This 'follows'? Every part of my body and my mind makes 'use' of every other part. My body uses my mind to achieve reproduction. He presumably means 'person' rather than 'man'. |
