‘But an invisible force was crushing him. He could feel its weight, its hypnotic power; it was forcing him to think as it wanted, to write as it dictated. This force was inside him; it could dissolve his will and cause his heart to stop beating (. . .) Only people who have never felt such a force themselves can be surprised that others submit to it. Those who have felt it, on the other hand, feel astonished that a man can rebel against it even for a moment – with one sudden word of anger, one timid gesture of protest.’12
