Ludwig Wittgenstein (1889-1951) was an Austrian-born philosopher and lecturer at Cambridge University. Tractatus Logico-Philosophicus was his only book published during his lifetime.
Tractatus Logico-Philosophicus (1921) is a singular and ground-breaking work of modern philosophy that attempts to illuminate the relationship between logic, language, and reality.
Philosophical Investigations (1953) documents the iconic thinker’s radical shift in understanding the nature of language and represents the culmination of his late career. It was incomplete on the author’s death and was published posthumously.
