Tractatus Logico-Philosophicus
He became editor of the "Berliner Tageblatt" in 1895, but is remembered mainly for his "Beiträge zu einer Kritik der Sprache" ("Contributions to a Critique of Language"), published in three parts in 1901 and 1902. Ludwig Wittgenstein took several of his ideas from Mauthner, and acknowledges him in his "Tractatus Logico-Philosophicus" (1922).
