Vision, A (1925; rev. edn. 1937), a prose work of mystical philosophy by W. B. Yeats, based on the automatic writings of his wife Georgie. This material encouraged him to systematize the theory of masks already outlined in Per Amica Silentiae Lunae (1918). Much of the work is given over to locating types of human personality and historical ages between the poles of extreme subjectivity and extreme objectivity, according to their place in a cyclical scheme of interesting gyres.
