The words “Life, Liberty, and the pursuit of Happiness” are in what founding document?

Why this is the answer

Those words are in the second sentence of the Declaration of Independence, where Thomas Jefferson lists the rights every person is born with. People often guess the Constitution, but the Constitution never uses the phrase; the closest it comes is the Fifth and Fourteenth Amendments, which speak of "life, liberty, or property". The difference is a good way to remember which document is which: the Declaration talks about the rights people have by nature, the Constitution about what the government may and may not do. Memory hook: "pursuit of Happiness" belongs to the Declaration.
