Early Wittgenstein

Wittgenstein developed a comprehensive system of logical atomism with a picture theory of meaning in his Tractatus Logico-Philosophicus (German: Logisch-Philosophische Abhandlung, 1921) sometimes known as simply the Tractatus. He claimed the universe is the totality of actual states of affairs and that these states of affairs can be expressed and mirrored by the language of first-order predicate logic. Thus a picture of the universe can be constructed by expressing facts in the form of atomic propositions and linking them using logical operators.

Wittgenstein thought he had solved all the problems of philosophy with the Tractatus. The work further ultimately concludes that all of its propositions are meaningless, illustrated with a ladder one must toss away after climbing up it.
