      "Not merely the translator or interpreter of other men's ideas, Shaw is, as the author of this comprehensive and extraordinarily illuminating little volume points out, a vigorous and original thinker himself who has foreseen in the social and intellectual crisis of his times a challenging need for a new synthesis of ideas and new goals for society.  He has worked to provide these solutions and the reader will find them well clarified in Mr. Fuller's careful analysis of his plays and the ideas they embody. No student of our world can afford not to evaluate the work of George Bernard Shaw."
