In a country -France- where the field of theater has been culturally structured for decades, Applied Theater is a notion that often appears as an ancillary, in the face of an institutionalized, even mirified, art. On the one hand, there would be the Theater, pure, noble, authentic and on the other, there would be its ups and downs: company theater, theater for personal development, theater for pathologies, etc. If they have the same source, their consanguinity does not stop frightening. How can some artists who create far from any external coercion belong to the same theater family as some actors or directors who "obey" a commission, in a specific context, with an audience that is often workshop participants... are they therefore prisoners, in a certain way, of an instrumented art? To this ethical problem, this book tries to respond, through concrete examples, for a greater intercultural understanding France/ Colombia.
