James Madison: Free examination of public characters and measures, free communication among the people
"The right of freely examining public characters and measures, and of free communication among the people thereon ... has ever been justly deemed the only effectual guardian of every other right."
-- James Madison, Virginia Resolutions, 1798
"The house of representatives ... can make no law which will not have its full operation on themselves and their friends, as well as the great mass of society. This has always been deemed one of the strongest bonds by which human policy can connect the rulers and the people together. It creates between them that communion of interest, and sympathy of sentiments, of which few governments have furnished examples; but without which every government degenerates into tyranny."
-- James Madison, Federalist No. 57, 1788
