Tractatus logico-philosophicus - Tapa blanda

"Tractatus Logico-Philosophicus may be the most important book of philosophy written during the twentieth century. Wittgenstein's writing style is clear, succinct, and accessible. Bertrand Russell claimed that "I cannot see any point on which it is wrong. But to have constructed a theory of logic which is not at any point obviously wrong is to have achieved a work of extraordinary difficulty and importance." Required ready for anyone interested in philosophy."
