We hold these truths to be sacred & undeniable; that all men are created equal & independant, that from that equal creation they derive rights inherent & inalienable, among which are the preservation of life, & liberty, & the pursuit of happiness; that to secure these ends, governments are instituted among men, deriving their just powers from the consent of the governed; that whenever any form of government shall become destructive of these ends, it is the right of the people to alter or to abolish it, & to institute new government, laying it’s foundation on such principles & organising it’s powers in such form, as to them shall seem most likely to effect their safety & happiness.

Thomas Jefferson (1743-1826) American political philosopher, polymath, statesman, US President (1801-09)
