Sartre and Koestler: Bisociation, Nothingness, and the Creative Experience in Roth's The Anatomy Lesson

What is the compatibility of Jean-Paul Sartre's Being and Nothingness and Arthur Koestler's Insight and Outlook, and what is the significance of those correspondences for the imagination of Philip Roth, as suggested by The Anatomy Lesson? Possible answers, as implied by Roth's narrative, suggest the pertinence of the philosophical and psychological concerns of Sartre and Koestler. Therein resides one of Roth's significant contributions to speculative philosophy and the history of ideas. Moreover, Roth's depiction, in narrator Nathan Zuckerman, of bisociated and existential consciousness is consistent with time-proven instances of ingenuity across the arts and sciences.
