Tractatus Logico-Philosophicus (Version 2) - Ludwig WITTGENSTEIN

The Tractatus Logico-Philosophicus is the only book published by Ludwig Wittgenstein. Any summary would frankly do the work an injustice - the interested reader is directed to Wittgenstein's preface and to the introduction of Wittgenstein's teacher, Bertrand Russell (1872-1970) - upon these no author could measurably improve. - (Summary by Landon D. C. Elkind)
