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.
