21681 | Given all true atomic propositions, in theory every other truth can thereby be deduced [Russell] |
Full Idea: Given all true atomic propositions, together with the fact that they are all, every other true proposition can theoretically be deduced by logical methods. | |
From: Bertrand Russell (Intro to 2nd ed of Principia Mathematica [1925], p.xv) | |
A reaction: This is evidently his strongest statement of the ideal underlying logical atomism. The atoms were initially sense-date, but then became atomic propositions saying an object has a property. |
18398 | 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. |
22186 | Mental modules are specialised, automatic, and isolated [Fodor, by Okasha] |
Full Idea: Fodor argues that mental modules have three important featuresL 1) they are domain-specific, 2) their operation is mandatory, 3) they are informationally encapsulated. | |
From: report of Jerry A. Fodor (The Modularity of Mind [1983]) by Samir Okasha - Philosophy of Science: Very Short Intro (2nd ed) 6 | |
A reaction: Mandatory is interesting. When I hear an English sentence I can't decide not to process it. Modules cannot be too isolated or they couldn't participate in the team. Each one needs a comms manager. |
