Frege's 1918 essay — the third realm of thoughts, distinct from physical and mental objects
Der Gedanke ("The Thought," 1918) is Gottlob Frege's late philosophical essay — the first of three "Logical Investigations" essays. The work develops Frege's mature philosophy of thought: thoughts (Gedanken) are not psychological-mental items but proper-abstract objects existing in a "third realm" distinct from physical objects (first realm) and mental events (second realm). Major source for late-Frege philosophy of language and mind.
