1770s, Declaration of Independence (1776)
Context: 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.

It was to be in the first instance, in a considerable degree, a government of accommodation as well as a government of laws. Much was to be done by prudence, much by conciliation, much by firmness. Few, who are not philosophical spectators, can realize the difficult and delicate part, which a man in my situation had to act. All see, and most admire, the glare which hovers round the external happiness of elevated office. To me there is nothing in it beyond the lustre, which may be reflected from its connection with a power of promoting human felicity.

On the United States Declaration of Independence, and the United States Constitution at the U.S. Bicentennial celebrations, Independence Hall, Philadelphia, Pennsylvania (4 July 1976)
1970s
Context: The Declaration was not a protest against government but against the excesses of government. It prescribed the proper role of government to secure the rights of individuals and to effect their safety and their happiness. In modern society, no individual can do this all alone, so government is not necessarily evil but a necessary good.
The framers of the Constitution feared a central government that was too strong, as many Americans rightly do today. The framers of the Constitution, after their experience under the Articles, feared a central government that was too weak, as many Americans rightly do today. They spent days studying all of the contemporary governments of Europe and concluded with Dr. Franklin that all contained the seeds of their own destruction. So the framers built something new, drawing upon their English traditions, on the Roman Republic, on the uniquely American institution of the town meeting.
