"Eugene O'Neill often characterized himself as a psychologist, asserting that "authors were psychologists...and profound ones, before psychology was invented." Though many of O'Neill's plays do reflect insights derived from early psychoanalytic method, contemporary students of psychology might bristle at O'Neil's characterization of his capacity to observe and describe the human condition. It might be better to characterize the so-called Father of American Tragedy as a kind of arm-chair philosopher, and this book attempts such a task. Through a close re- examination of Eugene O'Neill's oeuvre, from minor plays to his Pulitzer-winning works, this study proposes that O'Neill's philosophy of tragedy, though derivative of the larger Western approach to dramatic art, offers a unique account of why tragedy matters in today's world. In addition to offering a new paradigm through which to interpret O'Neill's work, this book argues that O'Neill's theory of tragedy is a robust description of the value of difficult theatre, with more explanatory scope and power than its historical counterparts. This volume enters the discussion of tragic value by way of the plays of Eugene O'Neill, and through this study, Killian makes the case that O'Neill refused to allow Plato to define the terms of tragedy's merit, as most Western theorists have. He argues that O'Neill's theory of tragedy is non-cognitive and locates the value of a play not in what we learn from it, but rather in its ability to make us feel emotions that are difficult to come by in everyday experience. This book is significant for students and scholars of performance studies, literature, and philosophy"--
