Nothing should stand in the way of the creation of a vigilant, sagacious, and high-minded diplomatic service. Men of small minds should content themselves with employment at home, where their errors may easily be repaired, for errors committed abroad are too often irreparable. The late Duke of Tuscany, who was a remarkably wise and enlightened prince, once complained to the Venetian ambassador, who stayed over-night with him on his journey to Rome, that the Republic of Venice had sent as resident at his court a person of no value, possessing neither judgment nor knowledge, nor even any attractive personal quality. ‘I am not surprised,’ said the ambassador in reply; ‘we have many fools in Venice.’ Whereupon the Grand Duke retorted: ‘We also have fools in Florence, but we take care not to export them.’ The Duke’s remarks show how important it is in every respect to choose the right man for the diplomatic service, and, in order to give the Foreign Minister an adequate freedom of choice, his diplomatic service should contain men of different characters and a wide variety of accomplishments. Thus he will not be compelled to send an unsuitable man merely because he was the only one available. He should have most careful regard in this choice to the type of government and the religion which prevails in the foreign country in question. There used to be a jest current in Paris on this very subject. The French King had sent a bishop to Constantinople and an heretic to Rome, and it was said that the one had gone to convert the Grand Turk and the other to be converted by the Pope!
