5 ideas

3. Truth / B. Truthmakers / 2. Truthmaker Relation
Propositions are made true, in virtue of something which explains its truth [Lowe]
     Full Idea: If a proposition is 'made' true, it has to be true 'in virtue of' something, meaning a relationship of metaphysical explanation. Thus a true proposition must have truth conferred on it in some way that explains how it gets to be true.
     From: E.J. Lowe (An essentialist approach to Truth-making [2009], p.202)
     A reaction: It is good to ask what we mean by 'makes'. I like essentialist explanations, but this may be misplaced. Observing that y makes x true seems to be rather less than actually explaining how it does it. What would such explanations look like?
6. Mathematics / A. Nature of Mathematics / 2. Geometry
One geometry cannot be more true than another [Poincaré]
     Full Idea: One geometry cannot be more true than another; it can only be more convenient.
     From: Henri Poincaré (Science and Method [1908], p.65), quoted by Stewart Shapiro - Philosophy of Mathematics
     A reaction: This is the culminating view after new geometries were developed by tinkering with Euclid's parallels postulate.
8. Modes of Existence / B. Properties / 8. Properties as Modes
Modes are beings that are related both to substances and to universals [Lowe]
     Full Idea: Modes are real beings that stand in non-contingent formal ontological relations both to individual substances and to immanent universals.
     From: E.J. Lowe (An essentialist approach to Truth-making [2009], p.212)
     A reaction: Not sure I understand this, but I pass it on. 'Modes' seem to invite the Razor, if we already have substances and universals. I am no clear about 'instantiation' because I now have the word 'mode' to play with.
8. Modes of Existence / B. Properties / 13. Tropes / b. Critique of tropes
Tropes have existence independently of any entities [Lowe]
     Full Idea: Pure trope theorists must apparently hold that each trope has its identity underivatively, not that it depends for it on or owes it to other entities of any sort.
     From: E.J. Lowe (An essentialist approach to Truth-making [2009], p.207)
     A reaction: Lowe defends dependent 'modes' of things, against independent 'tropes'. Good, but he then has to say what the thing is (a modeless 'substance'?), because it can't just be a bundle of modes or tropes.
12. Knowledge Sources / A. A Priori Knowledge / 2. Self-Evidence
A sentence is obvious if it is true, and any speaker of the language will instantly agree to it [Quine]
     Full Idea: A sentence is obvious if (a) it is true and (b) any speaker of the language is prepared, for any reason or none, to assent to it without hesitation, unless put off by being asked so obvious a question.
     From: Willard Quine (Reply to Hellman [1975], p.206), quoted by Paul Boghossian - Analyticity Reconsidered §III
     A reaction: This comes from someone who is keen to deny a priori knowledge, but what are we to make of the expostulations "It's obvious, you idiot!", and "Now I see it, it's obvious!", and "It seemed obvious, but I was wrong!"?
