READING THE GROWING NUMBER OF BOOKS and articles on the "social drama" of the American Depression, I am forced to conclude that we do not yet know what we are talking about. There seem to be two ambivalences which cause the student of Depression drama to spin on his heel, like Dorothy trying to get from the magical land of Oz back to the relatively familiar territory of Kansas. In the first place, there is no clear consensus about what social drama is, or about which plays are examples of it. Probably as a consequence of this ambivalence, we remain confused in our attitude towards whatever plays we think are social dramas. We are not sure whether they are good or bad, nor are we sure whether they represent a passing fancy of the period or a more stable (if less often recognized) type of drama common to several periods. Nevertheless we continue to talk about them because, as Professor Mendelsohn has said so well, "a nagging feeling remains that the protest plays provided the most exciting . . . theater of the period between the wars."
