The Tractatus Logico-Philosophicus (Latin for "Logical-Philosophical Treatise") is the only book-length philosophical work published by the German-Austrian philosopher Ludwig Wittgenstein in his lifetime. It was an ambitious project – to identify the relationship between language and reality and to define the limits of science[1] – and is recognized as a significant philosophical work of the twentieth century. G. E. Moore originally suggested the work's Latin title as homage to the Tractatus Theologico-Politicus by Baruch Spinoza.[2] Critical thinking web - StumbleUpon.
