Preface
To His Royal Highness, Monseigneur le Duc d'Orléans, Regent of the Kingdom.
Monseigneur,—This work, which I have the honour to present to your. Royal Highness, has for its aim: to give an idea of the personal qualities and general knowledge necessary in all good negotiators; to indicate to them the paths which they should follow and the rocks which they should avoid; and to exhort those who destine themselves to the foreign service of their country, to render themselves capable of discharging worthily that high, important, and difficult office before entering upon it.
The honour which the late King did me in charging me with his commands and his full powers for foreign negotiation, and particularly for those which led to the Treaty of Ryswick, has redoubled the attention which I have ever paid since my youngest years to my own instruction in the power, the rights, and the ambitions of each of the principal monarchies and states of Europe, in their divergent interests and the forms of their government, in the causes of their understandings and ​misunderstandings, and finally in the treaties which they have made one with another; in order to employ this knowledge to the best advantage whenever occasion offered in the service of my King and Country. After the loss which France has just suffered of that great King, whose reign was so full of glory and triumph, she did indeed need that the Hand of God, which has always upheld her in her necessities, should continue to guide her. We had indeed to look for Divine Help to support us during the minority of his present Majesty, so that we might hope that the All-Powerful Hand should mould a prince of like blood and spirit to him who has gone. The Regency needed an intelligence of the highest order, a capacity without limit, a clear insight into the character of persons and events, and an indefatigable activity which would increase at every new demand made by the interests of state—all these united in the person of a prince at once just, lovable, beneficent, whose character might earn for him the title of a veritable father of his country. These are the traits so strongly and so profoundly marked in you, Monseigneur, which have brought all France on its knees in homage before you, with full confidence and happiness, and a glorious prestige which shall pass undimmed to our remotest descendants as a worthy symbol of your great rule.
​I am, with profound respect, and with a zealous and affectionate attachment to your Person, Monseigneur,
Your Royal Highness's most humble, obedient, and faithful servant,
De CALLIÈRES.
