Locke was an influence on the founding fathers of our country. What two ideas did he contribute to the Enlightenment? Where in the founding documents of the United States do we see each of those ideas demonstrated? Make it as short as possible

John Locke contributed two key ideas to the Enlightenment: the belief in natural rights and the social contract theory. These ideas are demonstrated in the United States' founding documents. In the Declaration of Independence, the idea of natural rights is declared: "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." The idea of the social contract theory is evident in the Constitution, particularly in the preamble, which states the goal of forming "a more perfect Union" and establishing "justice" and "the blessings of liberty."
