The most important words in 18th century American history: “Life, liberty and the pursuit of happiness.”
In the 19th: “Government of the people, by the people, for the people.”
In the 20th:
First third: “We have nothing to fear but fear itself.”
Middle third: “I have a dream.”
Final third: “Can’t we all just get along?”
