Ludwig Wittgenstein (1889 – 1951) was an Austrian born British philosopher. Wittgenstein produced only one published book on philosophy (Tractatus Logico-Philosophus in 1921) while he was alive, but is nonetheless considered one of the most important thinkers of the twentieth century. He was born into a wealthy family in Austria, but would later gave away his inheritance to his family, stating that philosophy was the only work that gave him satisfaction.
Wittgenstein was a student of Russell. Russell described him as “the most perfect example I have ever known of genius as traditionally conceived; passionate, profound, intense, and dominating.” I have written previously regarding Russell’s unique style of Platonism, which emphasised the importance of terms. Wittgenstein, inspired by both Russell and Frege, takes this one step further in contending that all major philosophical problems have their being in the misunderstanding of the logic of language.
At the heart of the Wittgensteinian philosophy is the saying/showing distinction. Wittgenstein contended that what can be shown cannot be said. But if all philosophy is bound by language, then there are simply things that cannot be known. In this sense Wittgenstein channels Kant, where the necessary apparatus for making sense of experience are things that themselves cannot be experienced and known. In this way Wittgenstein shows the Kantian limitation of Frege-Russell logic, like a paradox it may explain all things but remains itself unexplained.
