8. Modes of Existence / C. Powers and Dispositions / 3. Powers as Derived
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?
11. Knowledge Aims / C. Knowing Reality / 2. Phenomenalism
If we are dreaming, it is sufficient that the events are coherent, and obey laws [Leibniz]
     Full Idea: Skeptics may doubt the truth of things, and if it pleases them to call the things that occur to us dreams, it suffices for these dreams to be in agreement with each other, and to obey certain laws.
     From: Gottfried Leibniz (On Perceptions [1680], A6.4.1398), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 7
     A reaction: Leibniz flirted a great deal with phenomenalism throughout the middle of his career, as charted by Garber. Descartes made similar points. It is really only Berkeley who took this idea seriously.
14. Science / A. Basis of Science / 4. Prediction
Successful prediction shows proficiency in nature [Leibniz]
     Full Idea: He who can finally make predictions with success must be said to have become sufficiently proficient in nature.
     From: Gottfried Leibniz (On Perceptions [1680], A6.4.1398), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 7
     A reaction: Is prediction achieved by knowledge of laws, or knowledge of essences and powers? The trouble with most laws is that they permit exceptions. 'Things fall, unless prevented' etc.
27. Natural Reality / G. Biology / 3. Evolution
Darwin's idea was the best idea ever [Dennett]
     Full Idea: If I were to give an award for the single best idea anyone has ever had, I'd give it to Darwin.
     From: Daniel C. Dennett (Darwin's Dangerous Idea [1995], §1.1)
