The quotation "all men are created equal" is found in the United States Declaration of Independence. The final form of the sentence was stylized by Benjamin Franklin and penned by Thomas Jefferson during the beginning of the Revolutionary War in 1776. It reads:
The phrase echoes the words of John Locke in his second treatise on government, and other authors as early as the 13th century. Jefferson applied the concept in his original draft of the declaration. It was thereafter quoted and incorporated into speeches by a wide array of substantial figures in American political and social life in the United States. It has been called an "immortal declaration", and "perhaps [the] single phrase" of the American Revolutionary period with the greatest "continuing importance."
Origins
The phrase is attested as early as pope Gregory the Great in book XXI of his Moralia in Job, and was picked up by Thomas Aquinas, Azo, Hervaeus Natalis, and other medieval thinkers.
Thomas Jefferson, through his friendship with Marquis de Lafayette, was heavily influenced by French philosophers of the Age of Enlightenment, such as Voltaire, Rousseau and Montesquieu. In their often censored writings, those philosophers advocated that men were born free and equal. This later led to the French Revolution of 1789 and the concept of Human Rights (Droits de l'Homme in French). At the age of 33, Jefferson may have also borrowed the expression from an Italian friend and neighbor, Philip Mazzei, born in Prato, as noted by Joint Resolution 175 of the 103rd Congress as well as by John F. Kennedy in A Nation of Immigrants.In English history there exists earlier uses of nearly the same phrase. First by the medieval priest John Ball who at the outbreak of the 1381 Peasants Revolt in his famous sermon posited the question "When Adam delved and Eve span, Who was then the gentleman?" and proclaimed "From the beginning all men by nature were created alike". In his 1690 work Second Treatise of Government the philosopher John Locke argues that in the "state of nature" that existed before the formation of governments all men were created equal. Another example is in John Milton's 1649 book called The Tenure of Kings and Magistrates, written after the First English Civil War to defend the actions and rights of the Parliamentary cause, in the wake of the execution of king Charles I. The English poet says: "No man who knows ought, can be so stupid to deny that all men naturally were borne free, being the image and resemblance of God himself ... born to command and not to obey: and that they liv'd so".
In 1776, the Second Continental Congress asked Benjamin Franklin, Thomas Jefferson, John Adams, Robert Livingston, and Roger Sherman to write the Declaration of Independence. This Committee of Five voted to have Thomas Jefferson write the document. After Jefferson finished he gave the document to Franklin to proof. Franklin suggested minor changes, one of which stands out far more than the others: "We hold these truths to be sacred and un-deniable..." became "We hold these truths to be self-evident."
The second paragraph of the United States Declaration of Independence starts: "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.-- That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed."
The Virginia Declaration of Rights, chiefly authored by George Mason and approved by the Virginia Convention on June 12, 1776, contains the wording: "all men are by nature equally free and independent, and have certain inherent rights of which . . . they cannot deprive or divest their posterity; namely, the enjoyment of life and liberty, with the means of acquiring and possessing property, and pursuing and obtaining happiness and safety." George Mason was an elder-planter who had originally stated John Locke's theory of natural rights: "All men are born equally free and independent and have certain inherent natural rights of which they cannot, by any compact, deprive or divest their posterity; among which are the enjoyment of life and liberty, with the means of acquiring and possessing property, and pursuing and obtaining happiness and safety." Mason's draft was accepted by a small committee and then rejected by the Virginia Convention. Thomas Jefferson, a competent Virginia lawyer, saw this as a problem in legal writing and chose words that were more acceptable to the Second Continental Congress.
