| 17962 | The truth-maker principle is that every truth has a sufficient truth-maker [Forrest] |
| Full Idea: Item x is said to be a sufficient truth-maker for truth-bearer p just in case necessarily if x exists then p is true. ...Every truth has a sufficient truth-maker. Hence, I take it, the sum of all sufficient truth-makers is a universal truth-maker. | |
| From: Peter Forrest (General Facts,Phys Necessity, and Metaph of Time [2006], 1) | |
| A reaction: Note that it is not 'necessary', because something else might make p true instead. |
| 12750 | The question is whether force is self-sufficient in bodies, and essential, or dependent on something [Lenfant] |
| Full Idea: The whole question is to know if the force to act in bodies is in matter something distinct and independent of everything else that one conceives there. Without that, this force cannot be its essence, and will remain the result of some primitive quality. | |
| From: Jacques Lenfant (Letters to Leibniz [1693], 1693.11.07), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 8 | |
| A reaction: This challenge to Leibniz highlights the drama of trying to simultaneously arrive at explanations of things, and to decide the nature of essence. Leibniz replied that force is primitive, because it is the 'principle' of behaviour and dispositions. |
| 2599 | Either intentionality causes things, or epiphenomenalism is true [Fodor] |
| Full Idea: The avoidance of epiphenomenalism requires making it plausible that intentional properties can meet sufficient conditions for causal responsibility. | |
| From: Jerry A. Fodor (Making Mind Matter More [1989], p.154) | |
| A reaction: A wordy way of saying we either have epiphenomenalism, or the mind had better do something - and a good theory will show how. The biggest problem of the mind may not be Chalmer's Hard Question (qualia), but how thought-contents cause things. |
| 2597 | Contrary to the 'anomalous monist' view, there may well be intentional causal laws [Fodor] |
| Full Idea: I argue that (contrary to the doctrine called "anomalous monism") there is no good reason to doubt that there are intentional causal laws. | |
| From: Jerry A. Fodor (Making Mind Matter More [1989], p.151) | |
| A reaction: I certainly can't see a good argument, in Davidson or anywhere else, to demonstrate their impossibility. Give the complexity of the brain, they would be like the 'laws' for weather or geology. |
| 2598 | Lots of physical properties are multiply realisable, so why shouldn't beliefs be? [Fodor] |
| Full Idea: If one of your reasons for doubting that believing-that-P is a physical property is that believing is multiply realizable, then you have the same reason for doubting that being an airfoil (or a mountain) counts as a physical property. | |
| From: Jerry A. Fodor (Making Mind Matter More [1989], p.153) | |
| A reaction: This merely points out that functionalism is not incompatible with physicalism, which must be right. |
