Disagreement produces debate but dissent produces dissension. Dissent (which come from the Latin, dis and sentire) means originally to feel apart from others. People who disagree have an argument, but people who dissent have a quarrel. People may disagree and both may count themselves in the majority. But a person who dissents is by definition in a minority. A liberal society thrives on disagreement but is killed by dissension. Disagreement is the life blood of democracy, dissension is its cancer.

Daniel J. BoorstinOur American past always speaks to us with two voices: the voice of the past, and the voice of the present. We are always asking two quite different questions. Historians reading the words of John Winthrop usually ask, What did they mean to him? Citizens ask, What do they mean to us? Historians are trained to seek the original meaning; all of us want to know the present meaning.
