19467 | A 'thought' is something for which the question of truth can arise; thoughts are senses of sentences [Frege] |
Full Idea: I call a 'thought' something for which the question of truth can arise at all. ...So I can say: thoughts are senses of sentences, without wishing to assert that the sense of every sentence is a thought. | |
From: Gottlob Frege (The Thought: a Logical Enquiry [1918], p.327-8 (61)) | |
A reaction: This builds on his distinction between sense and reference. The reference of every truth sentence is just 'the true', and the sense is the proposition. The concept of a proposition seems indispensable to logic, I would say. |
19472 | A sentence is only a thought if it is complete, and has a time-specification [Frege] |
Full Idea: Only a sentence with the time-specification filled out, a sentence complete in every respect, expresses a thought. | |
From: Gottlob Frege (The Thought: a Logical Enquiry [1918], p.343(76)) | |
A reaction: I take the 'every respect' to include the avoidance of ambiguity, and some sort of perspicacious reference for the terms. I wish philosophers would focus on the thoughts in their subject, and not nit-pick about the sentences. Does he mean 'utterances'? |
