Letter to Samuel Kercheval (1816)

Variant: Lay down true principles and adhere to them inflexibly. Do not be frightened into their surrender by the alarms of the timid, or the croakings of wealth against the ascendency of the people.

Volume I, Part IV : William the Conqueror
The History of England (1754-62)
Context: It was a fixed maxim in this reign, as well as in some of the subsequent, that no native of the island should ever be advanced to any dignity, ecclesiastical, civil, or military. The king therefore, upon Stigand’s deposition, promoted Lanfranc, a Milanese monk, celebrated for his learning and piety, to the vacant see. This prelate was rigid in defending the prerogatives of his station; and after a long process before the pope, he obliged Thomas, a Norman monk, who had been appointed to the see of York, to acknowledge the primacy of the archbishop of Canterbury. Where ambition can be so happy as to cover its enterprizes, even to the person himself, under the appearance of principle, it is the most incurable and inflexible of all human passions. Hence Lanfranc’s zeal in promoting the interests of the papacy, by which he himself augmented his own authority, was indefatigable; and met with proportionable success. The devoted attachment to Rome continually encreased in England; and being favoured by the sentiments of the conquerors, as well as by the monastic establishments formerly introduced by Edred and by Edgar, it soon reached the same height, at which it had, during some time, stood in France and Italy. It afterwards went much farther; being favoured by that very remote situation, which had at first obstructed its progress; and being less checked by knowledge and a liberal education, which were still somewhat more common in the southern countries.

Context: If civilization is to survive, the principles of the Prince of Peace must be restored. Shattered trust between nations must be revived. Most important of all, the will for peace on the part of peace-loving nations must express itself to the end that nations that may be tempted to violate their agreements and the rights of others will desist from such a cause. There must be positive endeavors to preserve peace. America hates war. America hopes for peace. Therefore, America actively engages in the search for peace.
