The founding values are more a historical curiosity than a living part of modern law and jurisprudence. From Andrew P. Napolitano at lewrockwell.com:
The Declaration of Independence — which was signed on July 3, 1776, for public release on July 4 — was Thomas Jefferson’s masterpiece. Jefferson himself wrote much about the declaration in the 50 years that followed.
Not the least of what he wrote offered his view that the declaration and the values that it articulated were truly radical — meaning they reflected 180-degree changes at the very core of societal attitudes in America. The idea that farmers and merchants and lawyers could secede from a kingdom and fight and win a war against the king’s army was the end result of the multigenerational movement that was articulated in the declaration.
The two central values of the declaration are the origins of human liberty and the legitimacy of popular government.
When Jefferson wrote that we are endowed by our Creator with certain inalienable rights, he was referring to the natural law. The natural law teaches that right and wrong can be discerned and truth discovered by the exercise of human reason, independent of any commands from the government. The natural law also teaches that our rights come from our humanity — not from the government — and our humanity is a gift from our Creator.
Even those who question or reject the existence of the Creator — was Jefferson himself among them? — can embrace natural rights, because they can accept that our exercise of human reason leads us all to make similar claims. These claims — free speech, free association, free exercise or non-exercise of religion, self-defense, privacy, and fairness, to name a few — are rights that we all exercise without giving a second thought to the fact that they are natural and come from within us.
The view of the individual as the repository of natural rights was not accepted by any governments in 1776. In fact, all rejected it and used violence to suppress it. To the minds of those in government in the mid-18th century, the king was divine and could do no wrong, and parliament existed not as the people’s representatives but to help the king raise money and to give him a read on the pulse of landowners and nobility.
