6 ideas

1. Philosophy / D. Nature of Philosophy / 2. Invocation to Philosophy
2118 All other human gifts can harm us, but not correct reasoning [Leibniz]
     Full Idea: Although people can be made worse off by all other gifts, correct reasoning alone can only be for the good.
     From: Gottfried Leibniz (Preface to Universal Characteristic [1679])
     A reaction: How about a kind heart? Not everyone would agree with the remark, but philosophers should.
1. Philosophy / E. Nature of Metaphysics / 1. Nature of Metaphysics
21959 Metaphysics is the most general attempt to make sense of things [Moore,AW]
     Full Idea: Metaphysics is the most general attempt to make sense of things.
     From: A.W. Moore (The Evolution of Modern Metaphysics [2012], Intro)
     A reaction: This is the first sentence of Moore's book, and a touchstone idea all the way through. It stands up well, because it says enough without committing to too much. I have to agree with it. It implies explanation as the key. I like generality too.
6. Mathematics / B. Foundations for Mathematics / 6. Mathematics as Set Theory / a. Mathematics is set theory
8463 Maths can be reduced to logic and set theory [Quine]
     Full Idea: Researches in the foundations of mathematics have made it clear that all of (interpreted) mathematics can be got down to logic and set theory, and the objects needed for mathematics can be got down to the category of classes (and classes of classes..).
     From: Willard Quine (The Scope and Language of Science [1954], §VI)
     A reaction: This I take to be a retreat from pure logicism, presumably influenced by Gödel. So can set theory be reduced to logic? Crispin Wright is the one the study.
8. Modes of Existence / B. Properties / 1. Nature of Properties
8461 The category of objects incorporates the old distinction of substances and their modes [Quine]
     Full Idea: The category of objects embraces indiscriminately what would anciently have been distinguished as substances and as modes or states of substances.
     From: Willard Quine (The Scope and Language of Science [1954], §6)
     A reaction: This nicely captures Quine's elimination of properties, by presenting them as inseparable from their objects/substances. Armstrong calls this 'Ostrich Nominalism' (for refusing to address the universals problem) but Quineans are unshaken.
11. Knowledge Aims / C. Knowing Reality / 3. Idealism / b. Transcendental idealism
21958 Appearances are nothing beyond representations, which is transcendental ideality [Moore,AW]
     Full Idea: Appearances in general are nothing outside our representations, which is just what we mean by transcendental ideality.
     From: A.W. Moore (The Evolution of Modern Metaphysics [2012], B535/A507)
17. Mind and Body / E. Mind as Physical / 6. Conceptual Dualism
8462 A hallucination can, like an ague, be identified with its host; the ontology is physical, the idiom mental [Quine]
     Full Idea: A physical ontology has a place for states of mind. An inspiration or a hallucination can, like the fit of ague, be identified with its host for the duration. It leaves our mentalistic idioms fairly intact, but reconciles them with a physical ontology.
     From: Willard Quine (The Scope and Language of Science [1954], §VI)
     A reaction: Quine is employing the same strategy that he uses for substances and properties (Idea 8461): take the predication as basic, rather than reifying the thing being predicated. The ague analogy suggests that Quine is an incipient functionalist.
