Answer: sorry it's so much
Explanation:
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.
From its magisterial opening phrase, which sets the American Revolution within the whole "course of human events," to its assertion that "the Laws of Nature and of Nature's God" entitle America to a "separate and equal station among the powers of the earth," to its quest for sanction from "the opinions of mankind," the introduction elevates the quarrel with England from a petty political dispute to a major event in the grand sweep of history.
Following this tradition, in July 1775 the Continental Congress issued its own Declaration Setting Forth the Causes and Necessity of Their Taking Up Arms. When, a year later, Congress decided the colonies could no longer retain their liberty within the British empire, it adhered to a long-established rhetorical convention by describing independence as a matter of absolute and inescapable necessity.6 Indeed, the notion of necessity was so important that in addition to appearing in the introduction of the Declaration, it was invoked twice more at crucial junctures in the rest of the text and appeared frequently in other congressional papers after July 4, 1776.7
If America and Great Britain were seen as one people, Congress could not justify revolution against the British government for the simple reason that the body of the people did not support the American cause.
This is achieved partly by the latent chronological progression of thought, in which the reader is moved from the creation of mankind to the institution of government, to the throwing off of government when it fails to protect the people's unalienable rights, to the creation of a new government that will better secure the people's safety and happiness.
