7. Existence / C. Structure of Existence / 7. Abstract/Concrete / a. Abstract/concrete

10578	We are thought to know concreta a posteriori, and many abstracta a priori [Yablo]
	Full Idea: Our knowledge of concreta is a posteriori, but our knowledge of numbers, at least, has often been considered a priori.
	From: Stephen Yablo (Abstract Objects: a Case Study [2002], 02)

10577	Concrete objects have few essential properties, but properties of abstractions are mostly essential [Yablo]
	Full Idea: Objects like me have a few essential properties, and numerous accidental ones. Abstract objects are a different story. The intrinsic properties of the empty set are mostly essential. The relations of numbers are also mostly essential.
	From: Stephen Yablo (Abstract Objects: a Case Study [2002], 01)

7. Existence / D. Theories of Reality / 10. Vagueness / d. Vagueness as linguistic

16458	Semantic vagueness involves alternative and equal precisifications of the language [Lewis]
	Full Idea: If vagueness is semantic indeterminacy, then wherever we have vague statements, we have several alternative precisifications of the vague language involved, all with equal claims of being 'intended'.
	From: David Lewis (Vague Identity: Evans misunderstood [1988], p.318)
