The Thought Written into the Declaration
Locke said man is born with rights to "life, liberty, and property," and government’s sole purpose is to protect them. Over eighty years later, Jefferson, drafting the American Declaration of Independence, all but transcribed this line of thought, only changing "property" to the more stirring "pursuit of happiness" — "all men are created equal, endowed with unalienable rights: life, liberty, and the pursuit of happiness." One philosopher’s study-bound thought became a nation’s founding declaration.
