Major Works is the first single-volume English anthology of Ludwig Wittgenstein's important philosophical writings. Featuring the complete
texts of Tractatus
Logico-Philosophicus, The Blue and Brown Books: Studies for 'Philosophical
Investigations,' and On Certainty, this new
collection selects from the early, middle, and later career of this
revolutionary thinker, widely recognized as one of the most profound minds of
all time. Wittgenstein contributed several groundbreaking ideas to philosophy, primarily in the foundations of logic, the philosophy of mathematics, the philosophy of language, and the philosophy of mind.
