8386 | Events are picked out by descriptions, and facts by whole sentences [Crane] |
Full Idea: Events are picked out using descriptions ('The death of Caesar'), while facts are picked out using whole sentences ('Caesar died'). | |
From: Tim Crane (Causation [1995], 1.4.2) | |
A reaction: Useful, and interesting. He mentions that Kim's usage doesn't agree with this. For analysis purposes, this means that an event is a more minimal item than a fact, and many facts will contain events as components. |
11016 | Would a language without vagueness be usable at all? [Read] |
Full Idea: We must ask whether a language without vagueness would be usable at all. | |
From: Stephen Read (Thinking About Logic [1995], Ch.7) | |
A reaction: Popper makes a similar remark somewhere, with which I heartily agreed. This is the idea of 'spreading the word' over the world, which seems the right way of understanding it. |
11019 | Supervaluations say there is a cut-off somewhere, but at no particular place [Read] |
Full Idea: The supervaluation approach to vagueness is to construe vague predicates not as ones with fuzzy borderlines and no cut-off, but as having a cut-off somewhere, but in no particular place. | |
From: Stephen Read (Thinking About Logic [1995], Ch.7) | |
A reaction: Presumably you narrow down the gap by supervaluation, then split the difference to get a definite value. |
11012 | A 'supervaluation' gives a proposition consistent truth-value for classical assignments [Read] |
Full Idea: A 'supervaluation' says a proposition is true if it is true in all classical extensions of the original partial valuation. Thus 'A or not-A' has no valuation for an empty name, but if 'extended' to make A true or not-true, not-A always has opposite value. | |
From: Stephen Read (Thinking About Logic [1995], Ch.5) |
11013 | Identities and the Indiscernibility of Identicals don't work with supervaluations [Read] |
Full Idea: In supervaluations, the Law of Identity has no value for empty names, and remains so if extended. The Indiscernibility of Identicals also fails if extending it for non-denoting terms, where Fa comes out true and Fb false. | |
