Some rights are for everyone. 
People have different kinds of rights. 
Other rights are legal rights. These come from the laws of a land. A government can change these laws. They can also make new ones.
Long ago, thinkers studied these ideas. They said life and liberty are very important. These are two big rights. Many people believe these rights belong to all.
Some people think all humans are equal. This helps people live in peace. It is a way to be fair to all.
People have different kinds of rights. Some are natural rights. These are rights we are born with. They are for everyone in the world. No government can take them away. 
Other rights are legal rights. These come from the laws of a country. A government can change or stop these rights.
Many thinkers studied these ideas long ago. Ancient Greek and Roman thinkers talked about natural law. They believed some rules come from nature. In the Middle Ages, thinkers like Thomas Aquinas studied these ideas too.
During the Age of Enlightenment, people used these ideas to change things. They used them to challenge kings. They believed in life and liberty. 
John Locke was a famous thinker. He said people have rights to life, liberty, and property. The United States Declaration of Independence used these ideas. It said people have rights to life and liberty. It also spoke of the pursuit of happiness. 
Some people do not agree. One thinker named Jeremy Bentham called natural rights "simple nonsense." But many others believe these rights help keep people free.
People often talk about different kinds of rights. Some thinkers say there are two main types. The first type is called natural rights. These are rights that belong to everyone in the world. They do not depend on the laws of a specific country. Because they are universal, no government can take them away. These are also called inalienable rights. This means they cannot be canceled by human laws. 
The second type is called legal rights. These rights come from a specific legal system. A government creates these rights through its own laws. Because humans make these laws, they can be changed. A government can also stop or limit legal rights. This is different from natural rights. Natural law is the idea that certain rights are part of nature. This is related to the idea of positive law. Positive law is the set of rules made by people. 
Ideas about natural law started a long time ago. Ancient Greek philosophers first talked about these ideas. Later, a Roman philosopher named Cicero spoke about them too. In the Middle Ages, Catholic thinkers studied them. Albert the Great and Thomas Aquinas were important thinkers here. Jean Gerson wrote about these ideas in 1402. During the Age of Enlightenment, these ideas became very powerful. People used them to challenge the power of kings. 
Many famous people have shared their ideas about rights. John Locke said people have rights to life, liberty, and property. In 1776, the United States Declaration of Independence used these ideas. It said people have rights to life and liberty. It also mentioned the pursuit of happiness. Other thinkers like T. H. Green focused on the right to life. Immanuel Kant said we can find these rights through reason. Even the Epicureans in ancient times had ideas about natural rules. 
Not everyone agrees that natural rights exist. A thinker named Jeremy Bentham called them "simple nonsense." Some people believe that only legal rights are real. Today, the idea of human rights comes from natural rights. The United Nations made a big statement in 1948. This was the Universal Declaration of Human Rights. It is a very important list of rights for everyone. However, it is not a law that every country must follow. It only becomes law if a country chooses to adopt it.
Philosophers often distinguish between two fundamental concepts: natural rights and legal rights. Natural rights are considered universal, fundamental, and inalienable. This means they do not depend on the laws or customs of any specific government or culture. Because they are inalienable, human laws cannot repeal them. However, a person might forfeit the enjoyment of these rights through their own actions, such as violating the rights of others. Natural law serves as the foundation for these rights. 
In contrast, legal rights are bestowed upon individuals by a specific legal system. These rights are closely related to the concept of positive law, which refers to the rules created by humans. Unlike natural rights, legal rights can be modified, repealed, or restrained by human authorities. While natural rights are seen as existing independently of government, legal rights exist only because a legal system recognizes them. This distinction is central to understanding how authority and individual freedom interact.
The history of natural law begins with ancient Greek philosophy. The Roman philosopher Cicero later discussed these ideas, arguing that justice is based on nature rather than mere opinion. During the Middle Ages, Catholic philosophers like Albert the Great and Thomas Aquinas further developed these concepts. In 1402, Jean Gerson wrote "De Vita Spirituali Animae," which is considered an early attempt at modern natural rights theory. These thinkers helped establish the idea that certain truths are part of a natural order. 
During the Age of Enlightenment, natural law became a tool to challenge the divine right of kings. It provided a justification for the social contract and classical republicanism. This era saw thinkers like John Locke argue that individuals possess rights to life, liberty, and estate, or property. These rights were seen as so fundamental that they could not be surrendered to a government. Later, the United States Declaration of Independence built upon these ideas. It stated that all men are endowed by their Creator with unalienable rights, specifically life, liberty, and the pursuit of happiness. 
Different philosophers have proposed different lists of these essential rights. Most agree that life and liberty are the highest priorities. The philosopher H. L. A. Hart argued that liberty is the most essential right, as all others depend upon it. T. H. Green also emphasized the necessity of a right to life and liberty. Even the Epicureans in the ancient world held views that implied personal sovereignty. They believed humans should consent to the laws that govern them through a contractarian ethics. 
Modern discussions often focus on the relationship between natural rights and human rights. Many view human rights as the successor to natural rights, though some argue they are not dependent on religious doctrine. A significant milestone is the 1948 United Nations Universal Declaration of Human Rights. While this is a major statement of natural rights, it is not legally binding on member states unless they adopt its provisions into their own laws. Additionally, the debate continues regarding whether rights are "negative" or "positive." Traditionally, natural rights were seen as negative rights, such as the duty not to harm others. Modern views reject this, suggesting human rights also include positive rights, which involve providing protection.
Despite their influence, the concept of natural rights is not universally accepted. Some philosophers, such as Jeremy Bentham, famously dismissed natural rights as "simple nonsense." Others argue that only legal rights actually exist. There is also a debate regarding the source of natural law. Some proponents of iusnaturalism believe legal norms follow universal human knowledge. Others attribute natural law to a divine mandate or a natural order. These differing perspectives continue to shape how societies define justice and the limits of government power.
