"Publicity is justly commended as a remedy for social and industrial diseases. Sunlight is said to be the best of disinfectants; electric light the most efficient policeman"
About this Quote
Brandeis turns a Progressive Era reform agenda into a pair of images so clean they feel inevitable: sickness and sanitation, darkness and crime. “Publicity” isn’t mere PR here; it’s radical transparency aimed at the era’s industrial trust-building, backroom deals, and regulatory capture. By calling corruption and exploitation “social and industrial diseases,” he frames them as systemic conditions, not isolated sins. You don’t cure them with scolding or charity; you cure them by changing the environment that lets them spread.
The genius is the double metaphor. “Sunlight” disinfects: exposure as hygiene. It assumes wrongdoing thrives in secrecy, and that being seen changes behavior even before any formal punishment arrives. Then he sharpens the point with a modern twist: “electric light,” a newer technology in his day, becomes “the most efficient policeman.” That’s not a sentimental faith in human goodness; it’s a hard-nosed theory of incentives. Surveillance by publicity is cheaper and more reliable than moral reform, and it recruits the public itself as witness and jury.
Subtextually, Brandeis is selling accountability without sounding partisan. He doesn’t argue policy details; he makes concealment look backward, almost unsanitary. In a moment when corporations were scaling faster than laws, and courts were central arenas for economic governance, he offers an elegant proposition: the first regulation is visibility. Make power legible, and it starts policing itself. The line’s staying power comes from that modern bargain it proposes - not perfect justice, but fewer places for abuse to hide.
