“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” (The United States Declaration of
Independence - July 4, 1776).
