8. Modes of Existence / B. Properties / 12. Denial of Properties

18439	Because things can share attributes, we cannot individuate attributes clearly [Quine]
	Full Idea: No two classes have exactly the same members, but two different attributes may be attributes of exactly the same things. Classes are identical when their members are identical. ...On the other hand, attributes have no clear principle of individuation.
	From: Willard Quine (On the Individuation of Attributes [1975], p.100)
