How is natural law different from man-made laws?
Natural law is a system of justice derived from nature, considered common to all humans, and is separate from societal rules or positive law. Natural law is viewed as being in accordance with reason inherent in the human mind.
Positive laws, or man-made laws, should be measured against objective moral truths to be considered valid laws. According to Cicero, a law that goes against natural law is not a real law, and St. Augustine of Hippo suggests that an unjust law isn't a law at all.

How has natural law influenced government laws or systems?
Natural law has significantly influenced government laws and systems, particularly in Western political philosophy. The concept, which posits the existence of a law whose content is set by nature and is universally valid, has been used to challenge unjust laws and advocate for fundamental rights.
Thinkers like John Locke articulated the theory of natural rights, arguing for inherent individual rights to life, liberty, and property, which governments cannot infringe. These ideas were instrumental in shaping constitutional law during the 17th, 18th, and 19th centuries, influencing documents like the English Bill of Rights, the American Declaration of Independence, and the French Declaration of the Rights of Man and of the Citizen.

What criticisms or challenges exist about the idea of natural law?
Natural law faces criticisms regarding its grounding in objective moral truths and its application across diverse societies. Skepticism arises from differing interpretations of "nature" and "reason," leading to varying moral and legal norms. Critics question whether natural law can truly be universal given cultural differences.
Some challenge the idea that morality can be derived from observing human nature, citing conflicting views on what constitutes natural human behavior. Others argue that natural law's reliance on reason may not adequately address the role of emotions and social factors in shaping laws. Despite these challenges, natural law persists as a basis for questioning unjust laws and advocating for human rights.

natural law, in philosophy, system of right or justice held to be common to all humans and derived from nature rather than from the rules of society, or positive law.
Early formulations of the concept of natural law
There have been several disagreements over the meaning of natural law and its relation to positive law. Aristotle (384ā322 bce) held that what was ājust by natureā was not always the same as what was ājust by law,ā that there was a natural justice valid everywhere with the same force and ānot existing by peopleās thinking this or that,ā and that appeal could be made to it from positive law. However, he drew his examples of natural law primarily from his observation of the Greeks in their city-states, who subordinated women to men, slaves to citizens, and ābarbariansā to Hellenes. In contrast, the Stoics conceived of an entirely egalitarian law of nature in conformity with the logos (reason) inherent in the human mind. Roman jurists paid lip service to this notion, which was reflected in the writings of St. Paul (c. 10ā67 ce), who described a law āwritten in the heartsā of the Gentiles (Romans 2:14ā15).
St. Augustine of Hippo (354ā430) embraced Paulās notion and developed the idea of manās having lived freely under natural law before his fall and subsequent bondage under sin and positive law. In the 12th century Gratian, an Italian monk and father of the study of canon law, equated natural law with divine lawāthat is, with the revealed law of the Old and New Testaments, in particular the Christian version of the Golden Rule.

St. Thomas Aquinas (c. 1224/25ā1274) propounded an influential systematization, maintaining that, though the eternal law of divine reason is unknowable to us in its perfection as it exists in Godās mind, it is known to us in part not only by revelation but also by the operations of our reason. The law of nature, which is ānothing else than the participation of the eternal law in the rational creature,ā thus comprises those precepts that humankind is able to formulateānamely, the preservation of oneās own good, the fulfillment of āthose inclinations which nature has taught to all animals,ā and the pursuit of the knowledge of God. Human law must be the particular application of natural law.
