Life, liberty and the pursuit of happiness
The phrase "life, liberty and the pursuit of happiness"
sums up the essence of the United States Declaration of Independence
Thomas Jefferson employed the phrase to emphasize his contention that government ought to be a contract between the rulers and the ruled, for the purpose of protecting citizen's lives and property -- much as John Locke had proposed earlier.
