On 12 September Wittgenstein arrived in Leningrad. There he met the author and educator Guryevich at the Northern Institute, then an autonomous faculty of Leningrad University. On the evening of the following day he travelled on to Moscow, arriving there on the morning of the 14th. Here he had contacts with various western Europeans and Americans, including the correspondent of the Daily Worker, Pat Sloane. Most of his discussions, however, were with scientists, for example the young mathematician Yanovskaya and the philosopher Yushevich from Moscow University, who were both close to so-called Mach Marxism and the Vienna Circle. He was invited by the philosopher Tatiana Nikolayeva Gornstein, a member of the Soviet Academy of Sciences, to teach philosophy at Leningrad University. He traveled to Kazakhstan, where he was offered a chair at the famous university where Tolstoy once studied. On 1 October he was back in Cambridge. The trip was shorter than planned, and it appears that he had given up the idea of settling in Russia.
His friend Gilbert Pattison, who picked him up from the ship on his return, recalled that Wittgenstein’s view was that he could not live there himself: One could live there, but only if one kept in mind the whole time that one could never speak one’s mind. ... It is as though one were to spend the rest of one’s life in an army, any army, and that is a rather difficult thing for people who are educated. (Interview with Pattison)
