Document Summary
Frege - the thought: a logical inquiry (1918) Anti-idealism -> objectivism about senses/thoughts -> thoughts as objects. In this paper, frege repeats the assertion that the thought is the sense of the sentence. Frege is at pains here to point out that thoughts are unlike material things(incorruptible), yet they are unlike mental contents. 299-301) central properties if odeas (look briefly at these), then proceeds to argue that thoughts are not like that. If the pythagorean theorem about right-angled triangles is true, it is and was always (so timelessly) true. If it is true that the sun has nine satellites then it is timelessly true. Now it surely cannot be sentences that are true or false (sentences as linguistic objects), since sentences are only of quite recent invention. Therefore it must be what sentences express that possess truth-values thus these must be timeless as well, and these are just what frege calls thoughts.
