n recent years, the post structuralist theories seem to have created a split in theatrological research. But, as André Helbo analyses in this book , a dialectic theory of the semiotic and the symbolic exchange bring to light a specific paradigm. From his wide experience as a semiotician and a theatrologist, the author has developed an analysis for the theory of spectacle. Focusing his study on a critical theory of the performing arts, and examining the fundamental controversies, he then offers new perspectives and new instruments of analysis: the social aspects, readability/visibility, coherence, the spectacle contract.
