4 ideas
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. |
14296 | Dispositions are physical states of mechanism; when known, these replace the old disposition term [Quine] |
Full Idea: Each disposition, in my view, is a physical state or mechanism. ...In some cases nowadays we understand the physical details and set them forth explicitly in terms of the arrangement and interaction of small bodies. This replaces the old disposition. | |
From: Willard Quine (The Roots of Reference [1990], p.11), quoted by Stephen Mumford - Dispositions 01.3 | |
A reaction: A challenge to the dispositions and powers view of nature, one which rests on the 'categorical' structural properties, rather than the 'hypothetical' dispositions. But can we define a mechanism without mentioning its powers? |
14470 | Explanatory exclusion: there cannot be two separate complete explanations of a single event [Kim] |
Full Idea: The general principle of explanatory exclusion states that two or more complete and independent explanations of the same event or phenomenon cannot coexist. | |
From: Jaegwon Kim (Mechanism, purpose and explan. exclusion [1989], 3) | |
A reaction: This is a rather optimistic view of explanations, with a strong element of reality involved. I would have thought there were complete explanations at different 'levels', which were complementary to one another. |
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. |
