9 ideas

7. Existence / B. Change in Existence / 2. Processes
Process philosophy insists that processes are not inferior in being to substances [Rescher]
     Full Idea: Process philosophy diametrically opposes the view that denies processes or downgrades them in the order of being or of understanding by subordinating them to substantial things.
     From: Nicholas Rescher (Process Metaphysics [1996]), quoted by R.D. Ingthorsson - A Powerful Particulars View of Causation 7
     A reaction: [No page cited - nr start?] Ingthorsson quotes this in order to challenge it, and says that substances are also processes, because change is essential to them.
8. Modes of Existence / B. Properties / 1. Nature of Properties
Properties only have identity in the context of their contraries [Elder]
     Full Idea: The very being, the identity, of any property consists at least in part in its contrasting as it does with its own proper contraries.
     From: Crawford L. Elder (Real Natures and Familiar Objects [2004], 2.4)
     A reaction: See Elder for the details of this, but the idea that properties can only be individuated contextually sounds promising.
9. Objects / B. Unity of Objects / 3. Unity Problems / c. Statue and clay
Maybe we should give up the statue [Elder]
     Full Idea: Some contemporary metaphysicians infer that one of the objects must go, namely, the statue.
     From: Crawford L. Elder (Real Natures and Familiar Objects [2004], 7.2)
     A reaction: [He cites Zimmerman 1995] This looks like a recipe for creating a vast gulf between philosophers and the rest of the population. If it is right, it makes the true ontology completely useless in understanding our daily lives.
9. Objects / C. Structure of Objects / 8. Parts of Objects / a. Parts of objects
In the military, persons are parts of parts of large units, but not parts of those large units [Rescher]
     Full Idea: In military usage, persons can be parts of small units, and small units parts of large ones; but persons are never parts of large units.
     From: Nicholas Rescher (Axioms for the Part Relation [1955]), quoted by Achille Varzi - Mereology 2.1
     A reaction: This much-cited objection to the transitivity of the 'part' relation seems very odd. There could hardly be an army or a regiment if there weren't soldiers to make up parts of it.
9. Objects / D. Essence of Objects / 6. Essence as Unifier
The loss of an essential property means the end of an existence [Elder]
     Full Idea: The loss of any essential property must amount to the end of an existence.
     From: Crawford L. Elder (Real Natures and Familiar Objects [2004], 3)
     A reaction: This is orthodoxy for essentialists, and I presume that Aristotle would agree, but I have a problem with the essence of a great athlete, who then grows old. Must we say that they lose their identity-as-an-athlete?
9. Objects / D. Essence of Objects / 9. Essence and Properties
Essential properties by nature occur in clusters or packages [Elder]
     Full Idea: Essential properties by nature occur in clusters or packages.
     From: Crawford L. Elder (Real Natures and Familiar Objects [2004], 2.2)
     A reaction: Elder proposes this as his test for the essentialness of a property - his Test of Flanking Uniformities. A nice idea.
Essential properties are bound together, and would be lost together [Elder]
     Full Idea: The properties of any essential nature are bound together....[122] so any case in which one of our envisioned familiar objects loses one of its essential properties will be a case in which it loses several.
     From: Crawford L. Elder (Real Natures and Familiar Objects [2004], 3)
     A reaction: This sounds like a fairly good generalisation rather than a necessary truth. Is there a natural selection for properties, so that only the properties which are able to bind to others to form teams are able to survive and flourish?
14. Science / D. Explanation / 2. Types of Explanation / j. Explanations by reduction
Six reduction levels: groups, lives, cells, molecules, atoms, particles [Putnam/Oppenheim, by Watson]
     Full Idea: There are six 'reductive levels' in science: social groups, (multicellular) living things, cells, molecules, atoms, and elementary particles.
     From: report of H.Putnam/P.Oppenheim (Unity of Science as a Working Hypothesis [1958]) by Peter Watson - Convergence 10 'Intro'
     A reaction: I have the impression that fields are seen as more fundamental that elementary particles. What is the status of the 'laws' that are supposed to govern these things? What is the status of space and time within this picture?
27. Natural Reality / A. Classical Physics / 1. Mechanics / a. Explaining movement
We only see points in motion, and thereby infer movement [Rescher]
     Full Idea: We perceive motion only as isolated points, and then infer it without actually seeing it.
     From: Nicholas Rescher (Scepticism [1980], §112)
     A reaction: Note how writing suddenly becomes readable as you slow down on entering a railway station. Is that points suddenly becoming unified? This is an empiricist endorsement of Russell's 'at-at' account of motion.
