Most importantly, the Declaration, the Constitution, and the Bill of Rights are based on the idea that all people have certain fundamental rights that governments are created to protect. Those rights include common law rights, which come from British sources like the Magna Carta, or natural rights, which, the Founders believed, came from God. The Founders believed that natural rights are inherent in all people by virtue of their being human and that certain of these rights are unalienable, meaning they cannot be surrendered to government under any circumstances.
