12695 | Epicurean atomists say body is sensible, to distinguish it from space. [Garber] |
Full Idea: The Epicurean atomists also defined body in terms of the property of being sensible, in order to distinguish it from empty space, which is not sensible. | |
From: Daniel Garber (Leibniz:Body,Substance,Monad [2009], 1) | |
A reaction: This is a very illuminating bit of background, for those of us who have the knee-jerk reaction that monadology is barking mad. |
5504 | Maybe we should see persons in four dimensions, with stages or time-slices at an instant [Martin/Barresi] |
Full Idea: Some recent philosophers have argued that we should replace the three-dimensional view of persons with a four-dimensional view according to which only time-slices, or 'stages', of persons exist at short intervals of time. | |
From: R Martin / J Barresi (Introduction to 'Personal Identity' [2003], p.3) | |
A reaction: At first glance this seems to neatly eliminate lots of traditional worries. But why would I want to retain my identity, if someone threatened to brainwash me. I also want to disown my inadequate earlier selves. Interesting, though. Lewis. |
5503 | Maybe personal identity is not vital in survival, and other continuations would suffice [Martin/Barresi] |
Full Idea: A modern question is whether personal identity is primarily what matters in survival; that is, people might cease and be continued by others whose continuation the original people would value as much. | |
From: R Martin / J Barresi (Introduction to 'Personal Identity' [2003], p.3) | |
A reaction: When put like this, the proposal seems hard to grasp. It only makes sense if you don't really believe in a thing called 'personal identity'. I don't see how you can believe in it without also believing that for you it has central importance. |
5502 | Locke's intrinsic view of personal identity has been replaced by an externalist view [Martin/Barresi] |
Full Idea: In modern times the Lockean intrinsic relations view of personal identity has been superseded by an extrinsic relations view (also called the 'closest-continuer' or 'externalist' view). | |
From: R Martin / J Barresi (Introduction to 'Personal Identity' [2003], p.1) | |
A reaction: Sounds sweeping. My suspicion is that there is a raging fashion for externalist views of everything (justification, content etc.), but this will pass. I take Parfit to be the source of the modern views. |
2605 | If everything uses mentalese, ALL concepts must be innate! [Putnam] |
Full Idea: Fodor concludes that every predicate that a brain could learn to use must have a translation into the computer language of that brain. So no "new" concepts can be acquired: all concepts are innate! | |
From: Hilary Putnam (What is innate and why [1980], p.407) | |
A reaction: Some misunderstanding, surely? No one could be so daft as to think that everyone has an innate idea of an iPod. More basic innate building blocks for thought are quite plausible. |
2606 | No machine language can express generalisations [Putnam] |
Full Idea: Computers have a built-in language, but not a language that contains quantifiers (that is, the words "all" and "some"). …So generalizations (containing "all") cannot ever be stated in machine language. | |
From: Hilary Putnam (What is innate and why [1980], p.408) | |
A reaction: Computers are too sophisticated to need quantification (which is crude). Computers can work with very precise and complex specifications of the domain of a given variable. |
12705 | Epicurean atoms are distinguished by their extreme hardness [Garber] |
Full Idea: In Epicurean atomism (of Cordemoy, for example) there is a world of basic things distinguished by virtue of their extreme hardness. | |
From: Daniel Garber (Leibniz:Body,Substance,Monad [2009], 2) | |
A reaction: Garber says that Leibniz espouses 'substantial atomism', which is different from this. Leibniz's atoms have active power, where these atoms just embody total resistance. |
5505 | For Aristotle the psyche perishes with the body (except possibly 'nous') [Martin/Barresi] |
Full Idea: In Aristotle's view, with the possible exception of 'nous' the psyche and all its parts come into being at the same time as its associated body; it is inseparable from the body, and perishes along with it. | |
From: R Martin / J Barresi (Introduction to 'Personal Identity' [2003], p.8) | |
A reaction: It is suggested that he thought there was only one 'nous', which all humans share (p.9). If he wants to claim that one part is immortal, he doesn't have much evidence. If psyche is the form of the body, it is bound to perish. |
