“A Conquest, without facing dangers is as dull as Victory without a shining glory. A game without a prize!”

Source: Utopia (1516), Ch. 8 : Of Their Military Discipline
Context: In no victory do they glory so much as in that which is gained by dexterity and good conduct without bloodshed. In such cases they appoint public triumphs, and erect trophies to the honour of those who have succeeded; for then do they reckon that a man acts suitably to his nature, when he conquers his enemy in such a way as that no other creature but a man could be capable of, and that is by the strength of his understanding. Bears, lions, boars, wolves, and dogs, and all other animals, employ their bodily force one against another, in which, as many of them are superior to men, both in strength and fierceness, so they are all subdued by his reason and understanding.

À vaincre sans péril, on triomphe sans gloire.

Napoleon : In His Own Words (1916)
Context: War is becoming an anachronism; if we have battled in every part of the continent it was because two opposing social orders were facing each other, the one which dates from 1789, and the old regime. They could not exist together; the younger devoured the other. I know very well, that, in the final reckoning, it was war that overthrew me, me the representative of the French Revolution, and the instrument of its principles. But no matter! The battle was lost for civilization, and civilization will inevitably take its revenge. There are two systems, the past and the future. The present is only a painful transition. Which must triumph? The future, will it not? Yes indeed, the future! That is, intelligence, industry, and peace. The past was brute force, privilege, and ignorance. Each of our victories was a triumph for the ideas of the Revolution. Victories will be won, one of these days, without cannon, and without bayonets.

Address to the Senate (22 January 1917)
1910s
Context: It must be a peace without victory... Victory would mean peace forced upon the loser, a victor's terms imposed upon the vanquished. It would be accepted in humiliation, under duress, at an intolerable sacrifice, and would leave a sting, a resentment, a bitter memory upon which terms of peace would rest, not permanently, but only as upon quicksand. Only a peace between equals can last.

Variant: I consider that the chief dangers which confront the coming century will be.... religion without the Holy Ghost, Christianity without Christ, forgiveness without repentance, salvation without regeneration, politics without God and heaven without hell.

1910s, Theodore Roosevelt — An Autobiography (1913)
Context: It is impossible to win the great prizes of life without running risks, and the greatest of all prizes are those connected with the home. No father and mother can hope to escape sorrow and anxiety, and there are dreadful moments when death comes very near those we love, even if for the time being it passes by. But life is a great adventure, and the worst of all fears is the fear of living.
