In all the arts that involve more than one performer, a crucially important artist is the director. (In music, his counterpart is the conductor.) The director is the link between the performing and the primary arts. He is a performer in relation to the primary work, in the sense that his task is the means to the end set by the work — he is a primary artist in relation to the cast, the set designer, the cameraman, etc., in the sense that they are the means to his end, which is the translation of the work into physical action as a meaningful, stylized, integrated whole. In the dramatic arts, the director is the esthetic integrator.This task requires a first-hand understanding of all the arts, combined with an unusual power of abstract thought and of creative imagination. Great directors are extremely rare. An average director alternates between the twin pitfalls of abdication and usurpation. Either he rides on the talents of others and merely puts the actors through random motions signifying nothing, which results in a hodgepodge of clashing intentions — or he hogs the show, putting everyone through senseless tricks unrelated to or obliterating the play (if any), on the inverted premise that the play is the means to the end of exhibiting his skill, thus placing himself in the category of circus acrobats, except that he is much less skillful and much less entertaining.
