From Paul Johnson’s superb book A History of the American People:
Jefferson produced a superb draft, for which his 1774 pamphlet was a useful preparation. All kinds of philosophical and political influences went into it. They were all well-read men and Jefferson, despite his comparative youth, was the best read of all, and he made full use of the countless hours he had spent pouring over books of history, political theory, and government.
The Declaration is a powerful and wonderfully concise summary of the best Whig thought over several generations. Most of all, it has an electrifying beginning. It is hard to think of any way in which the first two paragraphs can be improved:
WHEN in the Course of human Events, it becomes necessary for one People to dissolve the Political Bands which have connected them with another, and to assume among the Powers of the Earth, the separate and equal Station to which the Laws of Nature and of Nature’s God entitle them, a decent Respect to the Opinions of Mankind requires that they should declare the causes which impel them to the Separation.
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, that whenever any Form of Government becomes destructive of these Ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its Foundation on such Principles, and organizing its Powers in such Form, as to them shall seem most likely to effect their Safety and Happiness.
The first [paragraph], with its elegiac note of sadness at dissolving the union with Britain and its wish to show “a decent respect to the opinions of mankind” by giving its reasons; the second, with its riveting first sentence, the kernel of the whole: “We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain inalienable rights, that among these are life, liberty and the pursuit of happiness.” After that sentence, the reader, any reader � even George III � is compelled to read on.
The Committee found it necessary to make few changes in Jefferson’s draft. Franklin, the practical man, toned down Jefferson’s grandiloquence � thus truths, from being “sacred and undeniable” became “self-evident”, a masterly improvement. But in general the four others were delighted with Jefferson’s work, as well they might be.
Congress was a different matter because at the heart of America’s claim to liberty there was a black hole. What of the slaves? How could Congress say that “all men are created equal” when there were 600,000 blacks scattered through the colonies, and concentrated in some of them in huge numbers, who were by law treated as chattels and enjoyed no rights at all? Jefferson and the other members of the Committee tried to up-end this argument � rather dishonestly, one is bound to say � by blaming American slavery on the British and King George.
The original draft charged that the King had “waged a cruel war against human nature” by attacking a “distant people” and “captivating and carrying them into slavery in another hemisphere”. But when the draft went before the full Congress, on June 28, the Southern delegates were not having this. Those from South Carolina, in particular, were not prepared to accept any admission that slavery was wrong and especially the acknowledgment that it violated the “most sacred rights of life and liberty”. If the Declaration said that, then the logical consequence was to free all the slaves forthwith. So the slavery passage was removed, the first of many compromises over the issue during the next eighty years, until it was finally resolved inn an ocean of tears and blood. However, the word “equality” remained in the text, and the fact that it did so was, as it were, a constitutional guarantee that, eventually, the glaring anomaly behind the Declaration would be rectified.
The Congress debated the draft for three days. Paradoxically, delegates spent little time going over the fundamental principles it enshrined, because the bulk of the Declaration presented the specific and detailed case against Britain, and more particularly against the King. The Revolutionaries were determined to scrap the pretense that they distinguished between evil ministers and a king who “could do no wrong”, and renounce their allegiance to the crown once and for all. So they fussed over the indictment of the King, to them the core of the document, and left its constitutional and ideological framework, apart from the slavery point, largely intact.
This was just as well. If Congress had chosen to argue over Jefferson’s sweeping assumptions and propositions, and resolve their differences with verbal compromises, the magic wrought by his pen would surely have been exorcized, and the world would have been poorer in consequence.
As it was the text was approved on July 2, and on July 4 all the colonies formally adopted what was called, to give it its correct title, “The Unanimous Declaration of the Thirteen United States of America”. At the time, and often since, Tom Paine was credited with its authorship, which did not help to endear it to the British, where he was (and still is) regarded with abhorrence. In fact he had nothing to do with it directly, but the term “United States” is certainly his.
On July 8 it was read publicly in the State House Yard and the Liberty Bell rung. The royal coat of arms was torn down and burned. On August 2 it was engrossed on parchment and signed by all the delegates. Whereupon (according to John Hancock) Franklin remarked: “Well, Gentlemen, we must now hang together, or we shall most assuredly hang separately.”
