5. Theory of Logic / F. Referring in Logic / 1. Naming / b. Names as descriptive

10999	Names need a means of reidentifying their referents [Bradley, by Read]
	Full Idea: Unless a name has associated with it a means of reidentifying its referent, we cannot use it.
	From: report of F.H. Bradley (Appearance and Reality [1893]) by Stephen Read - Thinking About Logic Ch.4
	A reaction: Brilliant! This point is totally undeniable. It is not enough that someone be 'baptised'. We need to hang onto both the name and what it refers to, and how are we going to do that?

5. Theory of Logic / F. Referring in Logic / 3. Property (λ-) Abstraction

11863	(λx)[Man x] means 'the property x has iff x is a man'. [Wiggins]
	Full Idea: The Lambda Abstraction Operator: We can write (λx)[Man x], which may be read as 'the property that any x has just if x is a man'.
	From: David Wiggins (Sameness and Substance Renewed [2001], 4.2)
	A reaction: This technical device seems to be a commonplace in modern metaphysical discussions. I'm assuming it can be used to discuss properties without venturing into second-order logic. Presumably we could call the property here 'humanity'.
