Weaving together the stories and trajectories of these varied, fascinating, combative, and sometimes contradictory figures, Brad Snyder shows how their thinking about government and policy shifted from a firm belief in progressivism - the belief that the government should protect its workers and regulate monopolies - into what we call liberalism - the belief that government can improve citizens' lives without abridging their civil liberties and, eventually, civil rights. Holmes replaced Roosevelt in their affections and aspirations. His famous dissents from 1919 onward showed how the Due Process clause could protect not just business but equality under the law, revealing how a generally conservative and reactionary Supreme Court might embrace, even initiate, political and social reform.

Across the years, from 1912 until the start of the New Deal in 1933, the remarkable group of individuals associated with the House of Truth debated the future of America. They fought over Sacco and Vanzetti's innocence; the dangers of Communism; the role the United States should play the world after World War One; and thought dynamically about things like about minimum wage, child-welfare laws, banking insurance, and Social Security, notions they not only envisioned but worked to enact. American liberalism has no single source, but one was without question a row house in Dupont Circle and the lives that intertwined there at a crucial moment in the country's history.
