[Machine Translation] To be the ego is to act the ego. This book criticizes the idea of free will that precedes action, and explores the role that acting plays in life, using the concepts of "Jyo-bakkyu" and "Awa-no-mi" discovered by Zeaya, the great master of Noh drama, as the key. This groundbreaking work explores the role of acting in life. The book is supplemented by "The Aesthetics of Transformation," which discusses the aesthetics of Zeaya's pursuit of the extent to which human beings can be free while bearing a fundamental inconvenience.
