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) |
8942 | Lukasiewicz's L3 logic has three truth-values, T, F and I (for 'indeterminate') [Lukasiewicz, by Fisher] |
Full Idea: In response to Aristotle's sea-battle problem, Lukasiewicz proposed a three-valued logic that has come to be known as L3. In addition to the values true and false (T and F), there is a third truth-value, I, meaning 'indeterminate' or 'possible'. | |
From: report of Jan Lukasiewicz (Elements of Mathematical Logic [1928], 7.I) by Jennifer Fisher - On the Philosophy of Logic | |
A reaction: [He originated the idea in 1917] In what sense is the third value a 'truth' value? Is 'I don't care' a truth-value? Or 'none of the above'? His idea means that formalization doesn't collapse when things get obscure. You park a few propositions under I. |
20765 | Man is a brave naked will, separate from a background of values and realities [Murdoch] |
Full Idea: Existentialists no longer see man against a background of values, of realities, which transcend him. We picture man as a brave naked will. | |
From: Iris Murdoch (Against Dryness: a polemical sketch [1983], p.46), quoted by Kevin Aho - Existentialism: an introduction 7 'Subjectivism' | |
A reaction: It is one thing to deny the values, and another to deny the realities. This piece is a 'polemic', and reads more like an exhortation than a truth. Many of us are, at best, cowardly naked wills. |
