The fundamental points of the Tractatus Logic Philosophicus of Ludwig Wittgenstein

Presented in this article are the core aspects of Ludwig Wittgenstein's first philosophy starting from his conception of the world or reality (logical atomism) as a requirement of his construction of the preposition as figure (pictorial theory), whose logical structure allows to ascertain the preposition's general form and so establishing some limits to thought. The importance of each of these aspects is explained so to comprehend the relation language- world- thought, given that the whole of prepositions constitutes the language and the language figures the world thanks to thought.
