9. Objects / A. Existence of Objects / 5. Individuation / b. Individuation by properties

17668	It is likely that particulars can be individuated by unique conjunctions of properties [Armstrong]
	Full Idea: For each particular it is likely that there exists at least one individuating conjunction of properties, that is, a conjunction of properties such that the particular instantiates this conjunction and nothing else does.
	From: David M. Armstrong (What is a Law of Nature? [1983], 02.3)
	A reaction: Armstrong commits to a famous Leibniz view, but I don't see his grounds for it. There is nothing incoherent about nature churning out perfect replicas of things, such as quarks and electrons. Would we care if two pens were perfectly identical?

9. Objects / F. Identity among Objects / 5. Self-Identity

17680	The identity of a thing with itself can be ruled out as a pseudo-property [Armstrong]
	Full Idea: There is reason to rule out as pseudo-properties such things as the identity of a thing with itself.
	From: David M. Armstrong (What is a Law of Nature? [1983], 06.2)
	A reaction: Good on you, David.
