“The deadliest enemies of nations are not their foreign foes; they always dwell within their borders. And from these internal enemies civilization is always in need of being saved. The nation blest above all nations is she in whom the civic genius of the people does the saving day by day, by acts without external picturesqueness; by speaking, writing, voting reasonably; by smiting corruption swiftly; by good temper between parties; by the people knowing true men when they see them, and preferring them as leaders to rabid partisans or empty quacks.”

Speech in Amsterdam, March 12, 1941. Quoted in "The Trial of the Germans" - Page 468 - by Eugene Davidson - History - 1997

Res Gestae Divi Augusti

1900s, The Strenuous Life: Essays and Addresses (1900), National Duties
Context: We admit with all sincerity that our first duty is within our own household; that we must not merely talk, but act, in favor of cleanliness and decency and righteousness, in all political, social, and civic matters. No prosperity and no glory can save a nation that is rotten at heart. We must ever keep the core of our national being sound, and see to it that not only our citizens in private life, but, above all, our statesmen in public life, practice the old commonplace virtues which from time immemorial have lain at the root of all true national wellbeing.

Other Inquisitions (1952), The Modesty of History
Context: Only one thing is more admirable than the admirable reply of the Saxon king: that an Icelander, a man of the lineage of the vanquished, has perpetuated the reply. It is as if a Carthaginian had bequeathed to us the memory of the exploit of Regulus. Saxo Grammaticus wrote with justification in his Gesta Danorum: "The men of Thule [Iceland] are very fond of learning and of recording the history of all peoples and they are equally pleased to reveal the excellences of others or of themselves."
Not the day when the Saxon said the words, but the day when an enemy perpetuated them, was the historic date. A date that is a prophecy of something still in the future: the day when races and nations will be cast into oblivion, and the solidarity of all mankind will be established.

"Home is where our heart is" is an ancient saying, reported at least as early as 1847, in Joseph C. Neal, "Singleton Snippe. Who Married for a Living", Graham's Magazine (1847), p. 166: "Home is where the heart is; and Snippe's heart was a traveler—a locomotive heart, perambulating; and it had no tendencies toward circumscription and confine".
Garden party in the Palace Park: welcoming speech (September 1, 2016)
Context: It is not always easy to say where we are from, what nationality we are. Home is where our heart is – and that cannot always be confined within national borders.

The Sacred Pipe (1953)

Original French: Il faut étouffer les ennemis intérieurs et extérieurs de la République, ou périr avec elle ; or, dans cette situation, la première maxime de votre politique doit être qu’on conduit le peuple par la raison, et les ennemis du peuple par la terreur.
