To be true a sentence must express a proposition, and not be ambiguous or vague or just expressive [Lewis]
|
|
Full Idea:
Sentences or assertions can be derivately called true, if they succeed in expressing determinate propositions. A sentence can be ambiguous or vague or paradoxical or ungrounded or not declarative or a mere expression of feeling.

From:
David Lewis (Forget the 'correspondence theory of truth' [2001], p.276)
|
|
A reaction:
Lewis has, of course, a peculiar notion of what a proposition is - it's a set of possible worlds. I, with my more psychological approach, take a proposition to be a particular sort of brain event.

Space, time, and some other basics, are not causal powers [Ellis]
|
|
Full Idea:
Spatial, temporal, and other primary properties and relationships are not causal powers.
|
|
From:
Brian Ellis (Response to David Armstrong [1999], p.42), quoted by David M. Armstrong - Truth and Truthmakers 10.4
|
|
A reaction:
It is hard to see how time and space could actually be powers, but future results in physics (or even current results about 'fields') might change that.

Is the cosmos open or closed, mechanical or teleological, alive or inanimate, and created or eternal? [Robinson,TM, by PG]
|
|
Full Idea:
The four major disputes in classical cosmology were whether the cosmos is 'open' or 'closed', whether it is explained mechanistically or teleologically, whether it is alive or mere matter, and whether or not it has a beginning.
|
|
From:
report of T.M. Robinson (Classical Cosmology (frags) [1997]) by PG - Db (ideas)
|
|
A reaction:
A nice summary. The standard modern view is closed, mechanistic, inanimate and non-eternal. But philosophers can ask deeper questions than physicists, and I say we are entitled to speculate when the evidence runs out.
