5 ideas

3. Truth / A. Truth Problems / 5. Truth Bearers

10845	To be true a sentence must express a proposition, and not be ambiguous or vague or just expressive [Lewis]
	Full Idea: Sentences or assertions can be derivately called true, if they succeed in expressing determinate propositions. A sentence can be ambiguous or vague or paradoxical or ungrounded or not declarative or a mere expression of feeling.
	From: David Lewis (Forget the 'correspondence theory of truth' [2001], p.276)
	A reaction: Lewis has, of course, a peculiar notion of what a proposition is - it's a set of possible worlds. I, with my more psychological approach, take a proposition to be a particular sort of brain event.

3. Truth / B. Truthmakers / 2. Truthmaker Relation

10847	Truthmakers are about existential grounding, not about truth [Lewis]
	Full Idea: Instances of the truthmaker principle are equivalent to biconditionals not about truth but about the existential grounding of all manner of other things; the flying pigs, or what-have-you.
	From: David Lewis (Forget the 'correspondence theory of truth' [2001])
	A reaction: The question then is what the difference is between 'existential grounding' and 'truth'. There wouldn't seem to be any difference at all if the proposition in question was a simple existential claim.

3. Truth / B. Truthmakers / 11. Truthmaking and Correspondence

10846	Truthmaker is correspondence, but without the requirement to be one-to-one [Lewis]
	Full Idea: The truthmaker principle seems to be a version of the correspondence theory of truth, but differs mostly in denying that the correspondence of truths to facts must be one-to-one.
	From: David Lewis (Forget the 'correspondence theory of truth' [2001], p.277)
	A reaction: In other words, several different sentences might have exactly the same truthmaker.

11. Knowledge Aims / B. Certain Knowledge / 2. Common Sense Certainty

6349	I can prove a hand exists, by holding one up, pointing to it, and saying 'here is one hand' [Moore,GE]
	Full Idea: I can prove now that two human hands exist. How? By holding up my two hands, and saying, as I make a certain gesture with the right hand, 'Here is one hand', and adding, as I gesture with the left, 'and here is another'.
	From: G.E. Moore (Proof of an External World [1939], p.1)
	A reaction: The words need to be spoken, presumably, so that what he is doing fits into the linguistic conventions of what will normally be accepted as a proof. In fact, just holding the hand up seems enough. The proof begs the question of virtual reality.

21. Aesthetics / C. Artistic Issues / 7. Art and Morality

468	Musical performance can reveal a range of virtues [Damon of Ath.]
	Full Idea: In singing and playing the lyre, a boy will be likely to reveal not only courage and moderation, but also justice.
	From: Damon (fragments/reports [c.460 BCE], B4), quoted by (who?) - where?
