Tractatus Logico-Philosophicus

This book (also translated as "Tractatus Logico-Philosophicus") is a philosophical work formally published during Wittgenstein's lifetime. The translation was done by Wittgenstein expert Mr. Han Linhe, based on Wittgenstein's manuscript, from German, and includes extensive annotations.

The "Tractatus" discusses the relationship between thought, language, and the world in an aphoristic style; it emphasizes "the limits of language," distinguishing between "what can be said and what cannot be said." It then proposes "the theory of showing," specifically pointing to what "cannot be said but can only be shown." In the book, the author denies the law of causality, asserts that propositions in logic and mathematics are tautological, argues that all debated issues in the history of philosophy are meaningless, and that the task of philosophy is merely the logical analysis of language, i.e., the clarification of everyday language. It states that the fundamental and important attitude is: "Whereof one cannot speak, thereof one must be silent." This idea profoundly influenced the development of analytical philosophy.
