10 ideas
10911 | Part-whole is the key relation among truth-makers [Mulligan/Simons/Smith] |
Full Idea: The most important (ontological) relations holding among truth-makers are the part and whole relations. | |
From: Mulligan/Simons/Smith (Truth-makers [1984], §6) | |
A reaction: Hence Peter Simons goes off and writes the best known book on mereology. Looks very promising to me. |
10909 | Truth-makers cannot be the designata of the sentences they make true [Mulligan/Simons/Smith] |
Full Idea: Truth-makers cannot be the designata of the sentences they make true, because sentences with more than one truth-maker would then be ambiguous, and 'a' and 'a exists' would have the same designatum. | |
From: Mulligan/Simons/Smith (Truth-makers [1984], §3) |
10906 | Moments (objects which cannot exist alone) may serve as truth-makers [Mulligan/Simons/Smith] |
Full Idea: A 'moment' is an existentially dependent or non-self-sufficient object, that is, an object which is of such a nature that it cannot exist alone, ....... and we suggest that moments could serve as truth-makers. | |
From: Mulligan/Simons/Smith (Truth-makers [1984], §2) | |
A reaction: [These three writers invented the term 'truth-maker'] |
10907 | The truth-maker for a sentence may not be unique, or may be a combination, or several separate items [Mulligan/Simons/Smith] |
Full Idea: A proposition may have a minimal truth-maker which is not unique, or a sentence may be made true by no single truth-maker but only by several jointly, or again only by several separately. | |
From: Mulligan/Simons/Smith (Truth-makers [1984], §3) |
10912 | Despite negative propositions, truthmakers are not logical complexes, but ordinary experiences [Mulligan/Simons/Smith] |
Full Idea: Because of negative propositions, investigators of truth-makers have said that they are special non-objectual entities with a logical complexity, but we think a theory is possible in which the truth relation is tied to ordinary and scientific experience. | |
From: Mulligan/Simons/Smith (Truth-makers [1984], §6) |
10908 | Correspondence has to invoke facts or states of affairs, just to serve as truth-makers [Mulligan/Simons/Smith] |
Full Idea: The correspondence theory of truth invokes a special category of non-objectual entities - facts, states of affairs, or whatever - simply to serve as truth-makers. | |
From: Mulligan/Simons/Smith (Truth-makers [1984], §3) |
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. |
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. |
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. |
22186 | Mental modules are specialised, automatic, and isolated [Fodor, by Okasha] |
Full Idea: Fodor argues that mental modules have three important featuresL 1) they are domain-specific, 2) their operation is mandatory, 3) they are informationally encapsulated. | |
From: report of Jerry A. Fodor (The Modularity of Mind [1983]) by Samir Okasha - Philosophy of Science: Very Short Intro (2nd ed) 6 | |
A reaction: Mandatory is interesting. When I hear an English sentence I can't decide not to process it. Modules cannot be too isolated or they couldn't participate in the team. Each one needs a comms manager. |
