Republicanism stresses several key concepts; notably, the importance of civic virtue, the benefits of universal political participation, the dangers of corruption, the need for separate powers and a healthy reverence for the rule of law.
From these concepts, one paramount value stands apart -- political liberty. For Republicans, political liberty entails not only freedom from government interference in private affairs, it also places great emphasis on self-discipline and self-reliance. Political liberty keeps government out of individuals' lives (unless to do this threatens the republic as a whole), it also prevents the government from becoming a guardian to its individuals. The role of government in a republic is to safeguard the collective republic.
-- John Adams
Citizenship is what makes a republic; monarchies can get along without it.
-- Mark Twain
The true republic: men, their rights and nothing more; women, their rights and nothing less.
-- Susan B. Anthony
