The most famous words in the Declaration of Independence — and almost surely the most famous words ever written by an American — read, “We hold these Truths to be self-evident, that all Men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty, and the Pursuit of Happiness.”

On Friday evening, when President Obama addressed the Congressional Hispanic Caucus Institute, he quoted that passage as follows (on the clip at 22:30):  “We hold these truths to be self-evident, that all men are created equal [pause], endowed with certain unalienable rights:  life and liberty, and the pursuit of happiness.”
