(It was translated into English and published with its Latin title in 1922.) Focused on logic and metaphysical topics, it is considered among the most important philosophical works of the 20th century.

Tractatus Logico-Philosophicus also launched a reluctant Wittgenstein as one of the great thinkers of his time. Tractatus Logico-Philosophicus is structured around 525 declarative statements, or propositions, as it examines the roles and the significance of both language and science.
