7331 | A theory of meaning comes down to translating sentences into Fregean symbolic logic [Davidson, by Macey] |
Full Idea: For a theory of meaning for a fragment of natural language, what Davidson requires, in effect, is that the sentences be translatable into the language of Frege's symbolic logic. | |
From: report of Donald Davidson (In Defence of Convention T [1973]) by David Macey - Penguin Dictionary of Critical Theory | |
A reaction: This assumes the adequacy of Fregean logic, which seems unlikely. Is this the culmination of Leibniz's dream of a fully logical language - so that anything that won't fit into our logical form is ruled (logical positivist style) as meaningless? |
22489 | 'Good' is an attributive adjective like 'large', not predicative like 'red' [Geach, by Foot] |
Full Idea: Geach puts 'good' in the class of attributive adjectives, such as 'large' and 'small', contrasting such adjectives with 'predicative' adjectives such as 'red'. | |
From: report of Peter Geach (Good and Evil [1956]) by Philippa Foot - Natural Goodness Intro | |
A reaction: [In Analysis 17, and 'Theories of Ethics' ed Foot] Thus any object can simply be red, but something can only be large or small 'for a rat' or 'for a car'. Hence nothing is just good, but always a good so-and-so. This is Aristotelian, and Foot loves it. |
13605 | Gravity isn't a force, because it produces effects without diminishing [Mayer] |
Full Idea: If gravity be called a force, a cause is supposed which produces effects without itself diminishing, and incorrect conceptions of the causal connexions of things are thereby fostered. | |
From: J.R. Mayer (Remarks on the forces of inorganic Nature [1842], p.199), quoted by Brian Ellis - Scientific Essentialism 8.03 | |
A reaction: This seems like a brilliant prelude to the proposal that gravity is actually the 'curvature' of space (whatever that is!). |
