3.3 Only the proposition has sense; only in the context of a proposition does a name have meaning.
 
March 1915, Wittgenstein is sent to the Russian front to man an artillery night observation post. He sees combat, suffering, death. Diary prayers begin again. And philosophical notes on ethics: "The meaning of life, i.e. the meaning of the world, we can call God. To believe in God means to see that life has a meaning."

October 1915, Ludwig begins to recast as a book his work, his thinking on logic of the past three years. Wittgenstein: "My work has broadened out from the foundations of logic to the essence of the world." And: "The solution to the problem of life is to be seen in the disappearance of the problem."

July 1918, after many battles, after two citations for bravery under fire, Leutnant Ludwig Wittgenstein turns up in a Salzburg railway station, disoriented, distraught and suicidal. Uncle Paul coaxes him to his home in Hallein.

In Wittgenstein's pocket, a letter from David Pinsent's mother informing him that Pinsent is killed in an airplane accident two months before. Fanny Pinsent: "I want to tell you how much he loved you and valued your friendship up to the last."

August, 1918. In Hallein Ludwig finishes the manuscript he has rewritten so many times in the past three years, and dedicates it to: David Pinsent.
