8. Modes of Existence / B. Properties / 1. Nature of Properties
There cannot be uninstantiated properties [Aristotle, by Macdonald,C]
     Full Idea: Aristotle held that there could be no uninstantiated properties.
     From: report of Aristotle (Metaphysics [c.324 BCE], Bk 04) by Cynthia Macdonald - Varieties of Things
     A reaction: This is obviously a right hook aimed at Plato. Clearly we can think about uninstantiated properties, but the literal truth of Aristotle's view I would take to be tautological. To exist is to be instantiated.
Properties are just the ways in which forms are realised at various times [Aristotle, by Frede,M]
     Full Idea: On Aristotle's new theory it is forms that exist in their own right, whereas properties merely constitute the way forms of a certain kind are realized at some point of time in their existence.
     From: report of Aristotle (Metaphysics [c.324 BCE], props) by Michael Frede - Substance in Aristotle's 'Metaphysics' p.80
     A reaction: I'm not sure that 'merely' gives us enough of a story here. I never understand the word 'realised' (or 'instantiated', come to that). What does x have to do to realise y? Is that a relation between a real and a non-real thing?
The 'propriae' or 'necessary accidents' of a thing are separate, and derived from the essence [Aristotle, by Koslicki]
     Full Idea: Aristotle conceives of the necessary features of objects, traditionally known as the 'propria' or 'necessary accidents', as being distinct and derivate from, the essential features of objects.
     From: report of Aristotle (Metaphysics [c.324 BCE], props) by Kathrin Koslicki - Essence, Necessity and Explanation 13.1
     A reaction: This is a vague area, because Aristotle says very little about it. See Ideas 12266 and 12262. A particular shape of mole might be yours alone, but not part of your essence. That may be an 'idion' rather than a 'propria' (or are they the same?).
8. Modes of Existence / B. Properties / 2. Need for Properties
For two things to differ in some respect, they must both possess that respect [Aristotle]
     Full Idea: That which is different is different from something under some aspect, so that there must be something the same in respect of which they differ.
     From: Aristotle (Metaphysics [c.324 BCE], 1054b26)
8. Modes of Existence / B. Properties / 5. Natural Properties
For Aristotle, there are only as many properties as actually exist [Aristotle, by Jacquette]
     Full Idea: In Aristotle's metaphysics of substance, there are only as many properties as actually inhere in existent spatiotemporal particulars.
     From: report of Aristotle (Metaphysics [c.324 BCE], props) by Dale Jacquette - Ontology Ch.2
     A reaction: This would mean, oddly, that squareness ceased to be a property if the last square thing vanished. But then how do we establish the existence of unrealised properties? Is 'bigger than the biggest existent object' a property?
8. Modes of Existence / B. Properties / 8. Properties as Modes
Whiteness can be explained without man, but femaleness cannot be explained without animal [Aristotle]
     Full Idea: Whiteness can be explained without man, but femaleness cannot be explained without animal.
     From: Aristotle (Metaphysics [c.324 BCE], 1030b28)
     A reaction: This has to be a key basic distinction in any discussion of properties. But does the difference in explanation entail a difference in fundamental nature? Femaleness is structural.
8. Modes of Existence / B. Properties / 10. Properties as Predicates
If we only saw bronze circles, would bronze be part of the concept of a circle? [Aristotle]
     Full Idea: Suppose we only ever saw bronze circles - would that make the bronze a formal part of the circle?
     From: Aristotle (Metaphysics [c.324 BCE], 1036b01)
     A reaction: This is Aristotle spotting the problem of coextensionality (the renate/cordate problem) 2300 years ago. Don't underestimate those Greeks.
