5.4 Here it becomes clear that there are no such things as "logical objects" or "logical constants" (in the sense of Frege and Russell).
Frank Ramsey meets with him weekly, challenging his ideas. Ludwig: "A good objection helps one forward, a shallow objection, even if it is valid, is wearisome. Ramsey's objections are of this kind."

To bring him into the academic fold, Wittgenstein needs a doctorate, needs a stipend. He applies for a college grant, which many support. Ramsey: "He is a philosophic genius of a different order from anyone else I know."

He is hurriedly awarded a Ph.D. for his "thesis," the already published Tractatus. Moore and Russell administer the oral examination in June 1928. Russell: "I have never known anything so absurd in my life." Then, to Moore: "Go on, you've got to ask him some questions, you're the professor."

After a short inconclusive discussion of his book, Wittgenstein brings the proceedings to a close by standing and clapping them each on the shoulder. LW: "Don't worry, I know you'll never understand it."

With their uncomprehending approval, Wittgenstein receives the Ph.D. and a grant of £100 from Trinity College. He gives his first college lecture on 20 January, 1930, the day after young Frank Ramsey dies.
