Turning away from philosophical thought, from 1922 to 1928 Wittgenstein devoted himself to teaching elementary school in a small Austrian village, to architecture – he built his sister Margarete’s house – and to working as a gardener in a convent. The newly-founded, neo-positivist Vienna Circle took an interest in his work, which elicited rather cold reactions on Wittgenstien's part. | Turning away from philosophical thought, from 1922 to 1928 Wittgenstein devoted himself to teaching elementary school in a small Austrian village, to architecture – he built his sister Margarete’s house – and to working as a gardener in a convent.

In 1928, however, a conference held by mathematician Luitzen Brouwer (1881–1966) in Vienna reawakened Wittgenstein's interest in philosophy, convincing him to move back to Cambridge, where he obtained the teaching qualification. The years from 1928 to 1941 are remembered as a period in which the logical-philosophical theories of the ''Tractatus'' were thoroughly reconsidered: starting with the ''Lecture on Ethics'' (delivered in 1929), he revised and modified his ideas on language, logic, the foundations of mathematics, psychology, anthropology, and symbolic forms. The result of these reflections was collected in a series of manuscripts and typescripts written by Wittgenstein himself, or transcribed by his students during lectures. These include the ''Philosophical Remarks'', ''Philosophical Grammar'', the ''Big Typescript'', the ''[[Blue Book]]'' and the ''[[Brown Book]]'', and ''[[Zettel]].'' | In 1928, however, a conference held by mathematician Luitzen Brouwer (1881–1966) in Vienna reawakened Wittgenstein's interest in philosophy, convincing him to move back to Cambridge, where he obtained the teaching qualification.

During World War II, Wittgenstein served in a civilian hospital. Between 1947 and 1950 he spent time in England, Ireland, and the USA. Between 1949 and 1951 he wrote the remarks that were later published as ''[[Über Gewißheit|On Certainty]]''. But his best known and most memorable, albeit unfinished work from this period remains the ''[[Philosophische Untersuchungen|Philosophical Investigations]]'', the masterpiece of the “later” Wittgenstein, which, ever since its publication in 1953, has been fertile ground for contemporary philosophy. | During World War II, Wittgenstein served in a civilian hospital.
