8 ideas

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 / 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?
13. Knowledge Criteria / E. Relativism / 2. Knowledge as Convention
By nature people are close to one another, but culture drives them apart [Hippias]
     Full Idea: I regard you all as relatives - by nature, not by convention. By nature like is akin to like, but convention is a tyrant over humankind and often constrains people to act contrary to nature.
     From: Hippias (fragments/reports [c.430 BCE]), quoted by Plato - Protagoras 337c8
14. Science / B. Scientific Theories / 1. Scientific Theory
It seems obvious to prefer the simpler of two theories, on grounds of beauty and convenience [Quine]
     Full Idea: It is not to be wondered that theory makers seek simplicity. When two theories are equally defensible on other counts, certainly the simpler of the two is to be preferred on the score of both beauty and convenience.
     From: Willard Quine (On Simple Theories of a Complex World [1960], p.255)
     A reaction: A simple application of Ockham's Razor. Quine goes on to nicely deconstruct what is involved in simplicity, and identify a certain amount of dubious prejudice in the concept.
There are four suspicious reasons why we prefer simpler theories [Quine]
     Full Idea: We prefer simpler theories through wishful thinking, or a bias which slants the data, or a bias where the simpler hypothesis is more open to confirmation, or simpler hypotheses tolerating wider deviations in score-keeping.
     From: Willard Quine (On Simple Theories of a Complex World [1960], p.258)
     A reaction: [a compression of his summary of the paper] Quine is not dismissing our preference for simpler theories, but just very nicely inviting us to focus of aspects about which we should be cautious.
