As an Acting teacher my job is to give young artsts the tools nessacery to beepen thier craft. The problem is that communicating the essance of what the art is...and therefore what you excpect the student to achieve, is incredibly vague.
We talk about being honest in the moment, being open, and a raft of other sayings that we expect eveyone to understand but really thier unclear notions that if the student or even the fellow professional nod at like they know what the hell your talking about.
I've read and studied stanislavski, grotowski, adler, miesner, actors practical handbook, mierhold, and a host of other acting gurus and they all use a similiar language. But the thing is is that if we the artists/teachers can't clearly define these nebulous terms that we all aspire too then whats the use of the theories that they are based on.
I believe in things like play, brilliance, honesty in the work, and I love being an acting teacher....but i feel, and maybe mistakenly, that there is a hole in the craft...the hole of assuming what these basic terms we all use as acting teachers/acotrs/directors really mean. In the end this leads to the king has no clothes.
