He spent the year 1910-11 in France, attending Henri Bergson's lectures in philosophy at the Sorbonne and reading poetry with Alain-Fournier. Eliot's study of the poetry of Dante, of the English writers John Webster and John Donne, and of the French Symbolist Jules Laforgue helped him to find his own style. From 1911 to 1914 he was back at Harvard, reading Indian philosophy and studying Sanskrit. In 1913 he read Bradley's Appearance and Reality; by 1916 he had finished, in Europe, a dissertation entitled "Knowledge and Experience in the Philosophy of F.H. Bradley." But World War I had intervened, and he never returned to Harvard to take the final oral examination for the Ph.D. degree. In 1914 Eliot met and began a close association with the American poet Ezra Pound.
