We are the first nation on Earth founded on principles of human government rather than tribe, race, religion, culture or any other accident of birth. That is what I celebrate today. I celebrate a nation that serves a richly diverse people, respecting the human rights of each person under a system of equal justice for all, while protecting us and promoting our common welfare according to the will of ordinary citizens. Today I do not celebrate this land, which I do love, or our great accomplishments, of which I am proud, but rather the principles on which we were founded. And if we find that we are not living up to those founding principles as best we should, this is the day to renew our commitment to live by those principle that truly define us as Americans.
