A critic of modern dramaturgy with a bent for Brecht and O'Casey, the TNP and the Berliner Ensemble, Morgan and Frazer, Marx and Bloch, has one outstanding difficulty to come to terms with, if he is to be sincere to his trade and himself: Samuel Beckett. If the chief measure of a major dramatist is a happy union of relevance and consistency of dramatic vision, there is little doubt that in our cultural circle—middle and western Europe, based on the Mediterranean, with the massive wings of the Soviet Union and North America—the two major dramatists since World War II are Brecht and Beckett. Yet it is rare for a critic devoted to Beckett seriously and knowledgeably to face Brecht. I can think of only one such comprehensive effort—Martin Esslin's—and that one, to my mind, is finally unconvincing. Conversely, however, I can think of no critic of the Brechtian bent who has attempted a comprehensive study of Beckett.
