Introduction
The Age of Revolution (1962)
Context: Words are witnesses which often speak louder than documents. Let us consider a few English words, which were invented or gained their modern meanings, substantially in the period of sixty years with which this volume deals. They are such words as 'industry', 'industrialist', 'factory,' middle class,' 'working class,' and 'socialism.' They include 'aristocracy,' as well as 'railway,' 'liberal' and 'conservative' as political terms, 'nationality,'scientist,' and 'engineer,' 'proletariat,' and (economic) 'crisis'.

"The Honored Dead" (1863) memorialized the Union dead; a popular piece for declamation among schoolchildren, also published as "Our Heroes Shall Live"
Miscellany
Context: Oh, tell me not that they are dead — that generous host, that airy army of invisible heroes. They hover as a cloud of witnesses above this nation. Are they dead that yet speak louder than we can speak, and a more universal language? Are they dead that yet act? Are they dead that yet move upon society, and inspire the people with nobler motives, and more heroic patriotism?
Ye that mourn, let gladness mingle with your tears. It was your son, but now he is the nation's. He made your household bright: now his example inspires a thousand households. Dear to his brothers and sisters, he is now brother to every generous youth in the land. Before, he was narrowed, appropriated, shut up to you. Now he is augmented, set free, and given to all. Before, he was yours: he is ours. He has died from the family, that he might live to the nation. Not one name shall be forgotten or neglected: and it shall by and by be confessed of our modern heroes, as it is of an ancient hero, that he did more for his country by his death than by his whole life.
