18489 | Connectives link sentences without linking their meanings [MacBride] |
Full Idea: The 'connectives' are expressions that link sentences but without expressing a relation that holds between the states of affairs, facts or tropes that these sentences denote. | |
From: Fraser MacBride (Truthmakers [2013], 3.7) | |
A reaction: MacBride notes that these contrast with ordinary verbs, which do express meaningful relations. |
18476 | 'A is F' may not be positive ('is dead'), and 'A is not-F' may not be negative ('is not blind') [MacBride] |
Full Idea: Statements of the form 'a is F' aren't invariably positive ('a is dead'), and nor are statements of the form 'a isn't F' ('a isn't blind') always negative. | |
From: Fraser MacBride (Truthmakers [2013], 2.1.4) | |
A reaction: The point is that the negation may be implicit in the predicate. There are many ways to affirm or deny something, other than by use of the standard syntax. |
10001 | An adjective contributes semantically to a noun phrase [Hofweber] |
Full Idea: The semantic value of a determiner (an adjective) is a function from semantic values to nouns to semantic values of full noun phrases. | |
From: Thomas Hofweber (Number Determiners, Numbers, Arithmetic [2005], §3.1) | |
A reaction: This kind of states the obvious (assuming one has a compositional view of sentences), but his point is that you can't just eliminate adjectival uses of numbers by analysing them away, as if they didn't do anything. |
10007 | Quantifiers for domains and for inference come apart if there are no entities [Hofweber] |
Full Idea: Quantifiers have two functions in communication - to range over a domain of entities, and to have an inferential role (e.g. F(t)→'something is F'). In ordinary language these two come apart for singular terms not standing for any entities. | |
From: Thomas Hofweber (Number Determiners, Numbers, Arithmetic [2005], §6.3) | |
A reaction: This simple observations seems to me to be wonderfully illuminating of a whole raft of problems, the sort which logicians get steamed up about, and ordinary speakers don't. Context is the key to 90% of philosophical difficulties (?). See Idea 10008. |
