16209 | How can point-duration slices of people have beliefs or desires? [Thomson] |
Full Idea: Can one really think that point-duration temporal slices of bodies believe things or want things? | |
From: Judith (Jarvis) Thomson (People and Their Bodies [1997], p.211), quoted by Katherine Hawley - How Things Persist 2.9 n21 | |
A reaction: There is a problem with a slice doing anything long-term. The bottom line is that things are said to 'endure', but that is precisely what time-slices are unable to do. Hawley rejects this idea. |
6445 | You have knowledge if you can rule out all the relevant alternatives to what you believe [Dretske, by DeRose] |
Full Idea: The 'Relevant Alternatives' theory of knowledge said the main ingredient that must be added to true belief to make knowledge is that one be in a position to rule out all the relevant alternatives to what one believes. | |
From: report of Fred Dretske (Epistemic Operators [1970]) by Keith DeRose - Intro: Responding to Skepticism §6 | |
A reaction: Dretske and Nozick are associated with this strategy. There will obviously be a problem in defining 'relevant'. Otherwise it sounds quite close to Plato's suggestion that we need true belief with 'logos'. |
19399 | Prime matter is nothing when it is at rest [Leibniz] |
Full Idea: Primary matter is nothing if considered at rest. | |
From: Gottfried Leibniz (Aristotle and Descartes on Matter [1671], p.90) | |
A reaction: This goes with Leibniz's Idea 13393, that activity is the hallmark of existence. No one seems to have been able to make good sense of prime matter, and it plays little role in Aristotle's writings. |
