If you write about democratic theory, as I do, you will periodically get complaints that it is inaccurate to refer to the United States as a “democracy” because it is actually a “republic.” For example, several Facebook commenters and others have suggested that I should have titled my book Democracy and Political Ignorance (which focuses primarily on political ignorance in the United States) “The Republic and Political Ignorance” or something to that effect.
In the 18th century, “democracy” and “republic” were relatively distinct terms, with the former referring mainly to what we would today call “direct democracy,” of the sort practiced by the ancient Athenians.
