| 225 | The unlimited has no shape and is endless [Plato] |
| Full Idea: The unlimited partakes neither of the round nor of the straight, because it has no ends nor edges. | |
| From: Plato (Parmenides [c.364 BCE], 137e) |
| 233 | Some things do not partake of the One [Plato] |
| Full Idea: The others cannot partake of the one in any way; they can neither partake of it nor of the whole. | |
| From: Plato (Parmenides [c.364 BCE], 159d) | |
| A reaction: Compare Idea 231 |
| 2062 | The only movement possible for the One is in space or in alteration [Plato] |
| Full Idea: If the One moves it either moves spatially or it is altered, since these are the only motions. | |
| From: Plato (Parmenides [c.364 BCE], 138b) |
| 231 | Everything partakes of the One in some way [Plato] |
| Full Idea: The others are not altogether deprived of the one, for they partake of it in some way. | |
| From: Plato (Parmenides [c.364 BCE], 157c) | |
| A reaction: Compare Idea 233. |
| 16609 | Atomists say causation is mechanical collisions, and all true qualities are microscopic [Pasnau] |
| Full Idea: The atomist view is that causation is limited to collisions among corpuscles (which is 'mechanism'), and the only bodily qualities are those found at the microcorpuscular level; sensible qualities are in fact sensations. | |
| From: Robert Pasnau (Metaphysical Themes 1274-1671 [2011], 05.4) | |
| A reaction: [Part of a full summary of atomism by Pasnau] |
| 16603 | In the 17th C matter became body, and was then studied by science [Pasnau] |
| Full Idea: In the seventeenth century, matter becomes body, and body becomes the object of natural science. | |
| From: Robert Pasnau (Metaphysical Themes 1274-1671 [2011], 04.5) |
| 16592 | Atomism is the commonest version of corpuscularianism, but isn't required by it [Pasnau] |
| Full Idea: Atomism is the most common version of corpuscular prime matter, but it is not the only option. Indeed, atomism neither entails nor is entailed by the combination of corpuscularianism and the substratum thesis. | |
| From: Robert Pasnau (Metaphysical Themes 1274-1671 [2011], 03.2) | |
| A reaction: The point is that the corpuscles may be endlessly divisible (which Lewis called 'gunk'). |
| 16750 | If there are just arrangements of corpuscles, where are the boundaries between substances? [Pasnau] |
| Full Idea: If all there are corpuscles of various shapes and sizes, variously arranged, it is not easy to see how we might draw the boundary lines, at any given moment, between one substance and another. | |
| From: Robert Pasnau (Metaphysical Themes 1274-1671 [2011], 24.2) | |
| A reaction: We still have precisely that problem, and it leads to the nihilism about ordinary objects found in Unger, Van Inwagen and Merricks. I have so far found modern defences of ordinary objects unpersuasive. |
| 16722 | Scholastic causation is by changes in the primary qualities of hot, cold, wet, dry [Pasnau] |
| Full Idea: There is a scholastic theory of causation. Of Aristotle's Four Causes, the main one is the 'formal' cause, and that consists of changes in the primary, elemental qualities, which are hot, cold, wet and dry. | |
| From: Robert Pasnau (Metaphysical Themes 1274-1671 [2011], 21.2) | |
| A reaction: [my summary] It is probably right to call this 'scholastic' rather than 'Aristotelian', as I take Aristotelian essence to run deeper than this, and involve principles as well as qualities. |
| 16760 | Substantial forms were a step towards scientific essentialism [Pasnau] |
| Full Idea: Substantial forms might well be viewed as an early step in the development of scientific essentialism. | |
| From: Robert Pasnau (Metaphysical Themes 1274-1671 [2011], 24.4) | |
| A reaction: This is the scholastic view of substantial forms, which is much more physical and causal, rather than Aristotle's more abstract view. The rejection of substantial forms led to the 'Humean' view of laws of nature. |
