A Declaration by the Representatives of the United Colonies of North-America, Now Met in Congress at Philadelphia, Setting Forth the Causes and Necessity of Their Taking Up Arms.(1)
If it was possible for men, who exercise their reason to believe, that the divine Author of our existence intended a part of the human race to hold an absolute property in, and an unbounded power over others, marked out by his infinite goodness and wisdom, as the objects of a legal domination never rightfully resistible, however severe and oppressive, the inhabitants of these colonies might at least require from the parliament of Great-Britain some evidence, that this dreadful authority over them, has been granted to that body. But a reverance for our Creator, principles of humanity, and the dictates of common sense, must convince all those who reflect upon the subject, that government was instituted to promote the welfare of mankind, and ought to be administered for the attainment of that end. The legislature of Great-Britain, however, stimulated by an inordinate passion for a power not only unjustifiable, but which they know to be peculiarly reprobated by the very constitution of that kingdom, and desparate of success in any mode of contest, where regard should be had to truth, law, or right, have at length, deserting those, attempted to effect their cruel and impolitic purpose of enslaving these colonies by violence, and have thereby rendered it necessary for us to close with their last appeal from reason to arms. - Yet, however blinded that assembly may be, by their intemperate rage for unlimited domination, so to sight justice and the opinion of mankind, we esteem ourselves bound by obligations of respect to the rest of the world, to make known the justice of our cause.
