10782	The modern concept of an object is rooted in quantificational logic [Linnebo]
	Full Idea: Our modern general concept of an object is given content only in connection with modern quantificational logic.
	From: Øystein Linnebo (Plural Quantification Exposed [2003], §2)
	A reaction: [He mentions Frege, Carnap, Quine and Dummett] This is the first thing to tell beginners in modern analytical metaphysics. The word 'object' is very confusing. I think I prefer 'entity'.

9. Objects / F. Identity among Objects / 1. Concept of Identity

19394	Inequality can be brought infinitely close to equality [Leibniz]
	Full Idea: Equality may be considered as an infinitely small inequality, and we may make inequality approach equality as much as we wish.
	From: Gottfried Leibniz (A General Principle to Explain Laws of Nature [1687], p.67)
	A reaction: An interesting response to David Lewis's brusque dismissal of the problem of identity, as all-or-nothing...end of story.
