Lord Acton is author of the maxim, Power tends to corrupt, and absolute power tends to corrupt absolutely. A liberal Catholic and distinguished historian, Lord Acton produced vigorous denunciations of nationalism, racism, statism, and bigotry that rank among the classic works of political and social thought. ICS Press is proud to return to print Lord Acton: A Study in Conscience and Politics, first published by the University of Chicago Press in 1953 and out-of-print and unavailable for several years.
