François de Callières,
The Practice of Diplomacy
(1919)
“ To advance pretensions or to demand excessive privileges is merely the sign of pride and of a desire to extract from the privileged position of an ambassador a personal and unworthy advantage, in the doing of which an ambitious negotiator may easily and utterly compromise the whole authority of his master. No man who enters diplomacy in a spirit of avarice or with a desire to seek interests other than those of his service, or merely with the desire to earn the applause of the crowd, or to attract esteem and recompense from his master, will ever make success in negotiation. ”
