This chief aim of this title, first published in 1965, is to present a comprehensive picture of Yeats¿s achievement and some of the means for an evaluation of that achievement. To this end both the poems and plays have been examined and some of Yeats¿s critical ideas have been briefly discussed. Professor Rajan¿s study provides a compact introduction to Yeats¿s work, and will be of interest to the general reader as well as to students of literature.
