It’s salutary to remember that he was still only a twenty-three-year old undergraduate!

Whitehead of Principia Mathematica, a seminal work of mathematical logic.īut Wittgenstein quickly established complete intellectual dominance, so much so that by 1912 Russell told his sister that he expected the next big step in philosophy to be taken by her brother. The truly remarkable thing is that when the two met at Cambridge before the First World War Wittgenstein was a novice, Russell a mature and respected professor of philosophy, the author with A. Most who followed, particularly the Vienna School of Logical Positivists, which had as good a claim as any to be the apostles of the text, could not understand him.īertrand Russell, who wrote a preface for the Tractatus, could not understand his brilliant protégée. “If a lion could speak, we could not understand him”, he wrote in the posthumously published Philosophical Investigations.

Most of his life after the publication of the Tractatus was a pursuit of the very things that could not be touched on in a work of uncompromising logic, whether it be the nature of language, the way language is used in practical terms, the nature of thought, of ethics, of psychology, of the relationship of philosophy to the wider world of human experience. There you will find in all of its gnomic beauty one of the best remembered and most quoted propositions of all: Whereof we cannot speak thereof we must be silent. If you want to understand Ludwig Wittgenstein, the thinker and the man, turn to the very last page of Tractatus Logico-Philosophicus, the only philosophical work published in his lifetime.
