《独立宣言》第二段开头的字句：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.（译文：我们认为下面这些真理是不言而喻的 : 人人生而平等，造物者赋予他们若干不可剥夺的权利，其中包括生命权、自由权和追求幸福的权利。为了保障这些权利 ，人类才在他们之间建立政府，而政府之正当权力，是经被治理者的同意而产生的。）被称为“改变人类历史的五十五个字”而广为人知。
