“Nationalism in the West” is one of a series of lectures delivered throughout the United States during the winter of 1916-17. “Nationalism in Japan” is based upon two lectures delivered in Japan before the Imperial University and the Keio Gijuku University in June and July, 1916. “Nationalism in India,” written in the United States late in 1916, is the poet’s reflection upon the state of his own country, and gives world-wide completeness to the discussion of Nationalism. The poem at the conclusion of the book, “The Sunset of the Century,” was written on the last day of the last century.
