“The expressive coherence that is required in performances points out a crucial discrepancy between our all-too-human selves and our socialized selves. As human beings we are presumably creatures of variable impulse with moods and energies that change from one moment to the next. As characters put on for an audience, however, we must not be subjects to ups or downs. A certain bureaucratization of the spirit is expected so that we can be relied upon to give a perfectly homogenous performance at every appointed time.”
