Until the age of fifty and throughout all my youth, I dreamed of writing a book on the theory of comedy. Why? Because every book on the subject has been unsuccessful, at least all the ones I’ve been able to read. Every theoretician of comedy, from Freud to Bergson, explains some aspect of the phenomenon, but not all. This phenomenon is so complex that no theory is, or has been thus far, able to explain it completely. So I thought to myself that I would want to write the real theory of comedy. But then the task proved desperately difficult. If I knew exactly why it was so difficult, I would have the answer and I would be able to write the book.
