4 ideas

1. Philosophy / E. Nature of Metaphysics / 7. Against Metaphysics

16252	Metaphysics uses empty words, or just produces pseudo-statements [Carnap]
	Full Idea: Since metaphysics doesn't want to assert analytic propositions, nor fall within the domain of physical science, it is compelled to employ words for which no criteria of application are specified, ..or else combine meaningful words..into pseudo-statements.
	From: Rudolph Carnap (Elimination of Metaphysics by Analysis of Language [1959]), quoted by Tim Maudlin - The Metaphysics within Physics 2.4
	A reaction: A classic summary of the logical positivist rejection of metaphysics. I incline to treat metaphysics as within the domain of science, but at a level of generality so high that practising scientists become bewildered and give up.

6. Mathematics / A. Nature of Mathematics / 4. Using Numbers / c. Counting procedure

17462	A single object must not be counted twice, which needs knowledge of distinctness (negative identity) [Rumfitt]
	Full Idea: One requirement for a successful count is that double counting should be avoided: a single object should not be counted twice. ...but that is to make a knowledgeable judgement of distinctness - to resolve a question of identity in the negative.
	From: Ian Rumfitt (Concepts and Counting [2002], III)
	A reaction: He also notes later (p.65) that you must count all and only the right things.

6. Mathematics / B. Foundations for Mathematics / 5. Definitions of Number / c. Fregean numbers

17461	Some 'how many?' answers are not predications of a concept, like 'how many gallons?' [Rumfitt]
	Full Idea: We hit trouble if we hear answers to some 'How many?' questions as predications about concepts. The correct answer to 'how many gallons of water are in the tank?' may be 'ten', but that doesn''t mean ten things instantiate 'gallon of water in the tank'.
	From: Ian Rumfitt (Concepts and Counting [2002], I)
	A reaction: Rumfitt makes the point that a huge number of things instantiate that concept in a ten gallon tank of water. No problem, says Rumfitt, because Frege wouldn't have counted that as a statement of number.

27. Natural Reality / E. Cosmology / 1. Cosmology

5994	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.
