| 13468 | Russell started philosophy of language, by declaring some plausible sentences to be meaningless [Russell, by Hart,WD] |
| Full Idea: Russell inadvertently started the philosophy of language by declaring that some sentences (like "Everything is identical with itself") that seem utterly in order are meaningless and express no proposition. | |
| From: report of Bertrand Russell (Problems of Philosophy [1912]) by William D. Hart - The Evolution of Logic 2 | |
| A reaction: The normal candidate for this honour would be Frege, with the sense/reference distinction, but this idea sounds right to me. Declaring that some sentences are 'meaningless' really gets people excited and interested. I like the example! |
| 5388 | Every understood proposition is composed of constituents with which we are acquainted [Russell] |
| Full Idea: Every proposition which we can understand must be composed wholly of constituents with which we are acquainted. | |
| From: Bertrand Russell (Problems of Philosophy [1912], Ch. 6) | |
| A reaction: This is somewhere between Hume and logical positivism, but it concerns understanding (not meaning) of propositions (not sentences), and its acquaintance can be of universals as well as of sense experience. I like Russell's version more than Ayer's. |
