“Force is all-conquering, but its victories are short-lived.”

Quem faz injúria vil e sem razão,
Com forças e poder em que está posto,
Não vence; que a vitória verdadeira
É saber ter justiça nua e inteira.
Stanza 58, lines 5–8 (tr. Joaquim Nabuco)
Epic poetry, Os Lusíadas (1572), Canto X

人皆知我所以勝之形，而莫知吾所以制勝之形。

Music For All Of Us (1943); also quoted as "...Music can be all things to all persons... "
Context: I believe that music can be an inspirational force in all our lives — that its eloquence and the depth of its meaning are all-important, and that all personal considerations concerning musicians and the public are relatively unimportant — that music come from the heart and returns to the heart — that music is spontaneous, impulsive expression — that its range is without limit — that music is forever growing — that music can be one element to help us build a new conception of life in which the madness and cruelty of wars will be replaced by a simple understanding of the brotherhood of man.
Music can be all things to all men. It is like a great dynamic sun in the center of a solar system which sends out its rays and inspiration in every direction. … It is as if the heavens open and a divine voice calls. Something in our souls responds and understands. We are speaking here of the most inspired music.

Armageddon

Statement broadcast to the United States and the Pacific Fleet, after ceremonies in Tokyo Bay accepting the official surrender of Japan (2 September 1945); a portion of this is engraved on the National World War II Memorial in Washington, D.C.
Context: Today all freedom-loving peoples of the world rejoice in the victory and feel pride in the accomplishments of our combined forces. We also pay tribute to those who defended our freedom at the cost of their lives.
On Guam is a military cemetery in a green valley not far from my headquarters. The ordered rows of white crosses stand as reminders of the heavy cost we have paid for victory. On these crosses are the names of American soldiers, sailors and marines — Culpepper, Tomaino, Sweeney, Bromberg, Depew, Melloy, Ponziani — names that are a cross-section of democracy. They fought together as brothers in arms; they died together and now they sleep side by side. To them we have a solemn obligation — the obligation to insure that their sacrifice will help to make this a better and safer world in which to live. … Now we turn to the great tasks of reconstruction and restoration. I am confident that we will be able to apply the same skill, resourcefulness, and keen thinking to these problems as were applied to the problems of winning the victory.
