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?
9. Objects / D. Essence of Objects / 14. Knowledge of Essences
If there are essential properties, how do you find out what they are? [Chisholm]
     Full Idea: It seems to me that if Adam does have essential properties, there is no procedure at all for finding out what they are.
     From: Roderick Chisholm (Identity through Possible Worlds [1967], p.85)
     A reaction: My tentative suggestion is that the essential properties are those which explain the nature, power, function and role of Adam in the 'actual' world. Whatever possibilities he acquires, he had better retain the capacity to be the First Man.
10. Modality / E. Possible worlds / 3. Transworld Objects / a. Transworld identity
Could possible Adam gradually transform into Noah, and vice versa? [Chisholm]
     Full Idea: If Adam lived for 931 years in a possible world, instead of his actual 930 years, ..then Adam and Noah could gradually exchange their ages and other properties...and we could trace Adam in a world back to the actual Noah, and vice versa.
     From: Roderick Chisholm (Identity through Possible Worlds [1967], p.81-2)
     A reaction: [very compressed] Chisholm was one of the first to raise this problem for possible worlds, though it had been Quine's objection to modal logic all along. Only Adam having essential properties seems to stop this slippery slope, says Chisholm.
14. Science / C. Induction / 1. Induction
If you eliminate the impossible, the truth will remain, even if it is weird [Conan Doyle]
     Full Idea: When you have eliminated the impossible, whatever remains, however improbable, must be the truth.
     From: Arthur Conan Doyle (The Sign of Four [1890], Ch. 6)
     A reaction: A beautiful statement, by Sherlock Holmes, of Eliminative Induction. It is obviously not true, of course. Many options may still face you after you have eliminated what is actually impossible.
