So, was the American Revolution radical or conservative?
The American Revolutionaries' fight for liberty began as a conservative argument for rights as British subjects. However, the more radical nature of the American Revolution is evident when we look beneath the surface at the new argument Americans used to defend their rights: the higher-law principles of consent of the governed and natural rights. This radicalism, however, was tempered by the failure of the American founders to extend political rights to all those who naturally deserved them.
For the British, sovereignty resided with the "King in Parliament." The British government was a hybrid system with medieval elements of a hereditary monarchy and House of Lords. But, it also included a House of Commons, and system of rotten burroughs in which representation was not proportional to population. Although radical Whigs in Britain began to assert the doctrine of consent, most Whigs and Tories had to agree not to address any such principles of higher law because it would require their entire system to be reworked. They agreed to ignore the problem of consent and pretend the Glorious Revolution was just a moment of inconvenience.
As Americans agitated for their rights, the British continued to defend their system only on the grounds of customs and traditions of British law. In the "Summary of the View of Rights of British Americans," Thomas Jefferson tried to force the British to deal with the higher-order issue of consent. He blamed the King for failing to act as a negative against Parliament. Jefferson argued that colonial legislatures had equal authority with Parliament and it was the responsibility of the King to use his negative to protect the American colonies. But, of course, there was no such tradition that would allow these kinds of checks. It was only on the basis of higher-law principles of consent that the King could act in such a manner, and the British would not concede a higher law.
Edmund Burke recognized the problems inherent in British taxation of the American colonies. He argued that the British government should stop taxing the Americans because it would continue to raise questions about higher-law principles and point out contradictions in the British system. Nonetheless, the British continued to assert the right, through the Declaratory Act, to do as they wished because Parliament was supreme.
The Declaration of Independence was the Americans' magnum opus on higher-law rights. The Declaration listed grievances against the King for violations of the rights of colonists, but only after asserting a radical idea for the origins of rights: "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."
While the ideals of the Declaration and American Revolution were radical, the political realities were far from matching the rhetoric. Although some states outlawed slavery during and immediately after the American Revolution, the Constitution left in place a system of slavery that denied the most basic natural rights to enslaved African Americans. Frederick Douglass pointed out these contradictions in his 1852 speech, "What to the Slave is the Fourth of July?": "Are the great principles of political freedom and of natural justice, embodied in that Declaration of Independence, extended to us? I am not included within the pale of this glorious anniversary! ...The blessings in which you this day rejoice are not enjoyed in common. The rich inheritance of justice, liberty, prosperity, and independence bequeathed by your fathers is shared by you, not by me. ...This Fourth of July is yours, not mine. You may rejoice, I must mourn. ..."
Abolitionists of the 19th century (along with later women's rights and civil rights leaders) understood that the higher-law principles of the Declaration were the true foundation of freedom and equality. Setting out the aims of the American Anti-Slavery Society in 1833, William Garrison called liberty both an inalienable right and a God-given right. To deny another liberty, he reasoned, infringed upon both the “law of nature” and constituted a “presumptuous transgression of all the holy commandments.” He concluded the same manifesto by affirming the movement’s two foundational documents: The Declaration of Independence and the Bible. Garrison was critical of the Constitution for its concessions to slavery, especially the Three-Fifths compromise. He regarded this as a betrayal of both republicanism and Christianity.
The Declaration of Independence asserted the high and radical aims of the American Revolution: the Enlightenment principles of consent of the governed and natural rights. But forces of conservatism kept many from enjoying those rights until later generations of radicals led movements for political change.
