| 18519 | If there were infinite electrons, they could vanish without affecting total mass-energy [Heil] |
| Full Idea: In a universe containing an infinite number of electrons would mass-energy be conserved? ...Electrons could come and go without affecting the total mass-energy. | |
| From: John Heil (The Universe as We Find It [2012], 03.6) | |
| A reaction: This seems to be a very persuasive reason for doubting that the universe contains an infinite number of electrons. In fact I suspect that infinite numbers have no bearing on nature at all. (Actually, I suspect them of being fictions). |
| 18526 | We should focus on actual causings, rather than on laws and causal sequences [Heil] |
| Full Idea: I believe our understanding of causation would benefit from a shift of attention from causal sequences and laws, to instances of causation: 'causings'. | |
| From: John Heil (The Universe as We Find It [2012], 06.1) | |
| A reaction: His aim is to get away from generalities, and focus on the actual operation of powers which is involved. He likes the case of two playing cards propped against one another. I'm on his side. Laws come last in the story, and should not come first. |
| 18527 | Probabilistic causation is not a weak type of cause; it is just a probability of there being a cause [Heil] |
| Full Idea: The label 'probabilistic causation' is misleading. What you have is not a weakened or tentative kind of causing, but a probability of there being a cause. | |
| From: John Heil (The Universe as We Find It [2012], 06.5) | |
| A reaction: The idea of 'probabilistic causation' strikes me as an empty philosophers' concoction, so I agree with Heil. |
| 7016 | The standard view is that causal sequences are backed by laws, and between particular events [Heil] |
| Full Idea: The notion that every causal sequence if backed by a law, like the idea that causation is a relation among particular events, forms a part of philosophy's Humean heritage. | |
| From: John Heil (From an Ontological Point of View [2003], 04.3) | |
| A reaction: This nicely pinpoints a view that needs to come under attack. I take the view that there are no 'laws' - other than the regularities in behaviour that result from the interaction of essential dispositional properties. Essences don't need laws. |
