+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.
