Much of Wittgenstein’s writing was, at one remove, about aesthetics: questions of meaning, perception and emergence of sense. Yet there was little available explicitly about his aesthetics until notes from his lectures given by him in 1938 were collected and published in 1966 as Wittgenstein’s Lectures and Conversations on Aesthetics, Psychology, and Religious Belief
). The notes, taken by students Rush Rhees, Yorick Smythies, and James Taylor, together with notes on conversations about Freud and lectures on religious belief were edited by Cyril Barrett. Given the protective attitude Wittgenstein’s students had to his work and legacy, this was not a trivial task and the volume is probably his most enduring contribution to philosophy (eg see The Herald
, The Times (paywall)
What might surprise some is that this work was done by an Irish Jesuit. Born on 9th May 1925 in Dublin, Cyril Barrett graduated from UCD in 1947 with a first in Latin and History. Barrett entered the Society of Jesus in 1942 and was ordained in 1956. After teaching in various institutions he became one of the two founding members of the philosophy department in Warwick University in 1965, where he stayed until his retirement as reader in philosophy in 1992. After retirement he was a tutor in Oxford. He kept writing up to his last days in Milltown Dublin, where he died on 30th December 2003.
As well as Wittgenstein’s Lectures and Conversations, in 1990 Barrett published a commentary on Wittgenstein’s works, Wittgenstein on Ethics and Religious Belief. In this he argued that questions of value (ethics and religious belief) were of prime importance to Wittgenstein, and “intimately interwoven” in his thought.
