8446 | We understand new propositions by constructing their sense from the words [Frege] |
Full Idea: The possibility of our understanding propositions which we have never heard before rests on the fact that we construct the sense of a proposition out of parts that correspond to words. | |
From: Gottlob Frege (Letters to Jourdain [1910], p.43) | |
A reaction: This is the classic statement of the principle of compositionality, which seems to me so obviously correct that I cannot understand anyone opposing it. Which comes first, the thought or the word, may be a futile debate. |
8449 | Senses can't be subjective, because propositions would be private, and disagreement impossible [Frege] |
Full Idea: If the sense of a name was subjective, then the proposition and the thought would be subjective; the thought one man connects with this proposition would be different from that of another man. One man could not then contradict another. | |
From: Gottlob Frege (Letters to Jourdain [1910], p.44) | |
A reaction: This is an implicit argument for the identity of 'proposition' and 'thought'. This argument resembles Plato's argument for universals (Idea 223). See also Kant on existence as a predicate (Idea 4475). But people do misunderstand one another. |
