[13] Her publications Voices of Freedom (1943), What They Said at the Time: A Survey of the Causes of the Second World War (1945) and her work with the Philosophical Society of England, where she acted as Supervisor of Studies from 1948 to 1952 before becoming the Chairman in 1952, are further testimony to her desire to make Greek ideas accessible through translation.
