The characteristic intellectual failure of the critic of power is a lack of understanding of the limitations under which power is exercised. His characteristic moral failure lies in an excessive concern with his own purity; but purity of a sort is easily had where responsibilities are not assumed. The characteristic failure of the expert who advises the powerful is an unwillingness to bring his capacity for independent thought to bear as a source of criticism. He may lose his capacity for detachment from power by becoming absorbed in its point of view.
