5.641 The I occurs in philosophy through the fact that the "world is my world."
In his private tower rooms at Cambridge, Ludwig Wittgenstein paces before a circle of a dozen students and a few professors seated in folding canvas chairs sprawled skewwise all about. Professor G.E. Moore smokes his pipe, takes notes from the comfy leather armchair.

This is the lecture titled simply Philosophy. Students are invited individually by professors who feel they show promise. The course is not listed in the university roster because attendance would be too large. The Wittgenstein cult already flourishes, adoration of a Socratic teacher wrestling with his intellectual conscience.

Ray Monk: "He lectured without notes, and often appeared to be simply standing in front of his audience, thinking aloud. Occasionally he would stop, saying 'Just a minute, let me think!' and sit down for a few minutes, staring at his upturned hand. Sometimes the lecture would restart in response to the question from a particularly brave member of the class. Often he would curse his own stupidity, saying: 'What a damn fool I am!' or exclaiming vehemently: 'This is difficult as hell!'"

Ivor Richards: "Few could long withstand your haggard beauty, Disdainful lips, wide eyes bright-lit with scorn, Furrowed brow, square smile, sorrow-born World-abandoning devotion to your duty."
