Tom Stoppard has long been averse to weaving explicitly autobiographical material into his plays, so it’s only appropriate that one of his more revealing lines about himself would be voiced by a 19th-century liberal literary critic. The speech, which appears in Voyage, the first of Stoppard’s trilogy on the Russian intelligentsia, is delivered by Vissarion Belinsky to a small gathering of friends that includes a young “Michael” Bakunin and his aristocratic father.
