Final answer:
The Founding Fathers believed the idea of natural law should be rooted in justice and above man-made laws, reflecting Enlightenment values of inalienable universal rights like life and liberty.
Step-by-step explanation:
The Founding Fathers considered that the idea of natural law should be based on justice and transcend man-made law. These laws are seen as universal and inalienable, meaning they cannot be revoked by governments or international bodies. This notion is deeply rooted in the Enlightenment philosophy, where thinkers like John Locke influenced the Founding Fathers' belief in natural rights such as life, liberty, and property, matters that Thomas Jefferson included in the Declaration of Independence as 'the pursuit of happiness'. Additionally, natural rights are related to the laws of nature; this is reflected in the Declaration of Independence, which mentions the '...law of nature and nature's god'. The connection between natural law and civil liberties defined the political systems envisioned by the Enlightenment philosophers, contrasting sharply with the then-prevailing concept of the divine right of kings.
