"The official style is at once humble, polite, curt and disagreeable: it derives partly from that used in Byzantine times by the eunuch slave-secretariat, writing stiffly in the name of His Sacred Majesty, whose confidence they enjoyed, to their fellow-slaves outside the palace precincts — for the Emperor had summary power over everyone; and partly from the style used by the cleric-bureaucracy of the Middle Ages, writing stiffly in the name of the feudal lords to their serfs and, though cautious of offending their employers, protected from injury by being servants of the Church, not of the Crown, and so subject to canon, not feudal, law. The official style of civil servants, so far as it recalls its Byzantine derivation, is written by slaves to fellow-slaves of a fictitious tyrant; and, so far as it recalls its mediaeval derivation, is written by members of a quasi-ecclesiastical body, on behalf of quasi-feudal ministers (who, being politicians, come under a different code of behaviour from theirs) to a serflike public."
