Theory of Natural Law: A Comprehensive Guide
The theory of natural law is a legal and moral philosophy that posits that there is a higher law, derived from human nature, that is superior to human law. Natural law theorists believe that human beings are endowed with reason, and that this reason allows them to discern the basic principles of morality. These moral principles are universal and unchanging, and they provide a framework for evaluating human laws and institutions.
History of Natural Law Theory
The theory of natural law has a long and rich history, dating back to the ancient Greeks and Romans. Some of the most famous natural law theorists include Cicero, Aristotle, and Aquinas. In the Middle Ages, natural law theory was used to justify the authority of the Catholic Church and the European monarchies. However, natural law theory has also been used to challenge authority and to advocate for social reform.
Basic Principles of Natural Law Theory
Natural law theory is based on the following basic principles:
- Human beings are rational creatures. This means that we are able to think and reason about our actions, and to distinguish between right and wrong.
- Human beings have a natural inclination towards good. This means that we are naturally drawn to things that are good, such as truth, justice, and compassion.
- There is a universal moral law. This moral law is derived from human nature, and it is binding on all human beings.
- Human law should be consistent with natural law. If human law is inconsistent with natural law, then it is unjust and illegitimate.
How to Discern Natural Law
Natural law theorists use a variety of methods to discern the principles of natural law. Some common methods include:
- Reason: Natural law theorists believe that the basic principles of morality can be discerned through rational reflection on human nature.
- Scripture: Some natural law theorists believe that the principles of natural law are revealed in religious scripture.
- Tradition: Some natural law theorists believe that the principles of natural law are embedded in our cultural traditions.
- Conscience: Some natural law theorists believe that the principles of natural law can be discerned through our conscience, or inner sense of right and wrong.

- The right to life.
- The right to liberty.
- The right to property.
- The right to pursue happiness.
- The duty to tell the truth.

Natural law theory can be applied to a wide range of legal and social issues. For example, natural law theory has been used to:
- Justify the right to self-defense.
- Challenge the legitimacy of slavery and segregation.
- Argue against abortion and euthanasia.
- Defend the right to freedom of speech and religion.

Criticisms of Natural Law Theory
Natural law theory has been criticized on a number of grounds. One common criticism is that natural law theory is too vague and subjective. Critics argue that there is no objective way to determine the principles of natural law, and that different people will have different interpretations of these principles.
Another common criticism is that natural law theory is too conservative. Critics argue that natural law theory is used to justify the status quo and to resist social progress.
Despite its critics, the theory of natural law remains an influential force in law and morality. Natural law theory provides a framework for evaluating human laws and institutions, and it can be used to defend human rights and promote social justice.
Here are some additional examples of how natural law theory has been applied in the real world:
- The American Declaration of Independence states that “all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.” This statement is based on the natural law principle that all human beings have certain fundamental rights that cannot be taken away.
- The Universal Declaration of Human Rights, which was adopted by the United Nations in 1948, also reflects the influence of natural law theory. The Universal Declaration states that all human beings are born free and equal in dignity and rights. It also lists a number of specific human rights, such as the right to life, the right to liberty, and the right to freedom of thought and expression.
- Natural law theory has also been used to challenge the legitimacy of unjust laws. For example, the civil rights movement in the United States used natural law theory to argue that segregation laws were unjust and should be overturned. Similarly, the anti-apartheid movement in South Africa used natural law theory to argue that
