Natural law is a philosophical and legal theory. It suggests that certain laws exist within nature itself. These laws are based on universal moral principles. People can discover these principles by using human reason. In the field of ethics, this theory claims that specific rights and values are built into human nature. These values are understood by everyone, regardless of local customs or written laws. In jurisprudence, which is the study of law, natural law is sometimes called iusnaturalism. This view holds that objective moral standards exist beneath all human-made laws.

To understand natural law, one must compare it to positive law. Positive law refers to rules created by human authorities. These rules are often called legal positivism. Positive laws can change based on the needs of a specific society. In contrast, natural law remains constant because it is rooted in nature. Natural law can be applied to many different areas. It can cover theories of ethics, politics, civil law, or religious morality. The goal is to find practical principles that are grounded in the natural world.

The history of these ideas began in Ancient Greece. The pre-Socratics searched for principles that governed the cosmos. Plato believed the universe was an orderly place. He taught that the "Form of the Good" was the cause of all things. For Plato, seeing this Good led a person to act wisely. Aristotle is often called the father of natural law. He noted a distinction between local customs and a "common" law that follows nature. However, scholars still debate if Aristotle truly intended to create a formal theory of natural law.

The Stoics were responsible for developing natural law into a universal system. This growth happened as large empires and kingdoms rose in the Greek world. The Stoics believed the universe had a rational and purposeful order. They called this a divine or eternal law. They taught that a "divine spark" exists within every human being. This spark allows people to live in harmony with the natural order. This belief promoted the idea that all men are equal. This was a profound contribution to political thought.

In Ancient Rome, the philosopher Cicero expanded these ideas significantly. He argued that both justice and law come from nature. According to Cicero, law must serve the general good of society. He believed that laws should protect citizens and preserve the state. Cicero also claimed that wicked or unjust statutes are not true laws. To him, the very definition of law includes the principle of choosing what is just. His writings influenced legal thought for many centuries. His ideas reached through the Roman Empire and into the era of the American Revolution.

During the Middle Ages, Thomas Aquinas created a consistent system of natural law. He combined Aristotelian philosophy with Christian theology. Aquinas argued that because humans possess reason, their lives are sacred. He viewed reason as a spark of the divine. This meant that all people are fundamentally equal. Everyone is born with an intrinsic set of basic rights. These rights are so fundamental that no person or government can remove them.

Modern natural law took shape during the Age of Enlightenment. Thinkers combined Roman law and Christian philosophy with new social contract theories. This was used to challenge the "divine right of kings." It provided a new way to justify government and legal rights. John Locke was a key figure during this era. He used natural law to support property rights and the right to revolution. Today, the concept remains very important. It is closely linked to the idea of natural rights. Many scholars use the terms natural law and natural justice almost interchangeably.
