What is the author's tone in Towards a Poor Theatre by Grotowski?

Tone varies in this book, as it is a collection of interviews, essays, and notes, and thus authorship (and therefore, persona) is variable. Of chief interest is Grotowski's persona, both as the progenitor of the theory the book is based upon, and as an author in many of the essays and interviews. His persona is that of a well-read, intelligent academic who is appealing to a narrow, specific audience, those passionate about the theatre and stage acting. He uses an impressively broad vocabulary, several neologisms, and the kind of formal rhetorical style one might expect from an academic essay or artistic manifesto.
