Tractatus Logico-Philosophicus
Drafted in notebooks kept during his service in the Austro-Hungarian army from 1914 and completed in 1918, it appeared in German in 1921 and in a bilingual edition in 1922 with an introduction by Bertrand Russell that Wittgenstein felt misread it. It was the only philosophical book he published. Readers still dispute whether its nonsense conveys ineffable insights or is meant to dissolve itself completely.
