# Tractatus Logico-Philosophicus |  | The **Tractatus Logico-Philosophicus** is the only book-length philosophical work by the Austrian philosopher Ludwig Wittgenstein that was published during his lifetime. The project had a broad goal: to identify the relationship between language and reality, and to define the limits of science. Wittgenstein wrote the notes for the Tractatus while he was a soldier during World War I and completed it during a military leave in the summer of 1918. It was originally published in German in 1921 as Logisch-Philosophische Abhandlung. In 1922 it was published together with an English translation and a Latin title, which was suggested by G. E. Moore as homage to Baruch Spinoza's Tractatus Theologico-Politicus (1670). | |-|-| | | wikipedia:: [Tractatus Logico-Philosophicus](https://en.wikipedia.org/wiki/Tractatus_Logico-Philosophicus) | ## Also By ```dataview TABLE WITHOUT ID file.link AS Name, by AS By, in AS In, of AS Of, date AS Date, year AS Year FROM #Type WHERE ( ( contains(by, this.file.name) OR contains(by, this.file.link) OR any(contains(by, this.by)) AND by ) AND file.name !=this.file.name ) SORT file.etags DESC, date DESC, year DESC ```
