Conscience: Two Soldiers, Two Pacifists, One Family--a Test of Will and Faith in World War I(ISBN=9781594202940)

　　Conscience moves from the gothic buildings of Princeton to the tenements of New York City, from the West Wing of the White House to the battlefields of France, tracking how four young men navigated a period of great uncertainty and upheaval. A Thomas family member herself (Norman was Louisa's great grandfather), Thomas proposes that there is something we might recover from the brothers' debates about conscience: a way of talking about personal liberty and social obligation, about being true to oneself and to one another.

　　Two became soldiers. Ralph enlisted right away, heeding President Woodrow Wilson's call to fight for freedom. A captain in the Army Corps of Engineers, he was ultimately wounded in France. Arthur, the youngest, was less certain about the righteousness of the cause but sensitive to his obligation as a citizen-and like so many men eager to have a chance to prove himself. The other two were pacifists. Evan became a conscientious objector, protesting conscription; when the truce was signed on November 11, 1918, he was in solitary confinement. Norman left his ministry in the tenements of East Harlem, New York, and began down the course he would follow for the rest of his life, fighting for civil liberties, social justice, and greater equality, and against violence as a method of change. Conscience reveals the tension among responsibilities, beliefs, and desires, between ideas and actions-and, sometimes, between brothers.
