The fundamental difference between natural law and human law lies in their origin, universality, and immutability. While natural law is rooted in universal moral principles inherent to human nature and discoverable by reason, human law (also known as positive law) is created by societies, governments, or rulers to govern specific communities at particular times.
Understanding Natural Law
Natural law refers to a system of moral and ethical principles that are believed to be inherent in human nature and can be discovered by reason alone. It is often seen as a higher law, existing independently of human conventions and applicable to all people, everywhere, and at all times.
Key characteristics of natural law include:
- Universality: It applies to all humans, regardless of their culture, religion, or societal structure.
- Immutability: Its core principles are unchanging, reflecting fundamental truths about right and wrong.
- Inherent: It is believed to be embedded within the very fabric of human existence and the natural order.
- Discoverable by Reason: Humans can discern natural law through their rational faculties, by reflecting on human nature and the common good.
Examples of Natural Law Principles:
- The inherent right to life and self-preservation.
- The understanding that killing an innocent person is morally wrong.
- The obligation to seek truth and avoid ignorance.
- The principle of keeping promises or agreements.

Understanding Human Law (Positive Law)
Human law, also known as positive law, refers to the statutory laws, regulations, and ordinances that are formally enacted and enforced by a governing authority, such as a state or a government. Unlike natural law, human law is a product of human deliberation and societal agreement.
As philosopher Thomas Aquinas noted, human law is "an ordinance of reason for the common good," made and enforced by a ruler or government. This means it is designed to promote order, justice, and the well-being of a specific community.
Key characteristics of human law include:
- Variability: It can vary significantly with time, place, and circumstance, reflecting the specific needs and values of a particular society.
- Enacted: It is formally created through legislative processes and written down.
- Enforceable: It carries sanctions or penalties for non-compliance, enforced by the state.
- Specific: It applies to the citizens within the jurisdiction of the governing body that enacted it.
Examples of Human Law:
- Traffic laws (e.g., speed limits, rules of the road).
- Tax codes and financial regulations.
- Criminal statutes (e.g., laws against theft, assault).
- Property laws and contract laws.

Key Distinctions at a Glance
To clarify the differences, consider the following comparison:
| Feature | Natural Law | Human Law (Positive Law) |
|---|---|---|
| Origin | Inherent in human nature, universal reason | Enacted by human authority (governments, legislatures) |
| Scope | Applies to all humans universally | Applies to specific societies or jurisdictions |
| Immutability | Unchanging and timeless | Variable; can change over time, place, and circumstance |
| Enforcement | Conscience, moral obligation | State apparatus (police, courts, prisons) |
| Basis | Moral principles, justice, common good | Societal order, practicality, specific needs |
| Discovery | Through reason and reflection | Through legislation, decrees, and official documents |
The Relationship Between Natural Law and Human Law
Ideally, human law should be derived from and consistent with natural law. Laws that contradict fundamental natural law principles are often considered unjust or illegitimate by proponents of natural law theory. For instance, a human law permitting widespread torture might be seen as unjust because it violates the natural law principle of respecting human dignity.
- Foundation: Natural law provides a moral foundation or benchmark against which human laws can be evaluated.
- Guidance: It guides lawmakers in creating just and equitable legislation that serves the true common good.
- Critique: Natural law allows for a moral critique of positive laws, suggesting that not all legally enacted laws are necessarily morally right.
Practical Implications and Examples
Understanding the distinction between natural and human law has significant practical implications, particularly in legal philosophy, ethics, and governance:
- Civil Disobedience: The concept of natural law often forms the basis for arguments for civil disobedience, where individuals may feel morally obligated to defy unjust human laws that violate higher moral principles.
- International Law: Many principles of international human rights law (e.g., prohibition of genocide, torture) are deeply rooted in concepts akin to natural law, positing universal rights that transcend national borders.
- Constitutionalism: Many modern constitutions, particularly those that include bills of rights, reflect an attempt to codify fundamental natural rights into supreme human law that cannot be easily abrogated by ordinary legislation.
For example:
- A natural law principle is that all humans deserve basic respect and dignity.
- A human law based on this principle might be the Universal Declaration of Human Rights, which outlines fundamental rights and freedoms for all people.
- Conversely, a human law that sanctioned slavery would be considered unjust and in violation of natural law principles by many.
In essence, while natural law represents the 'ought'—what should be—based on inherent moral truth, human law represents the 'is'—what is enacted—by societal authority, ideally striving to align with the 'ought'.
