John Locke is the most prominent figure associated with the theory of natural rights. In his 'Two Treatises of Government', he argued that all individuals possess inherent, inalienable rights to life, liberty, and property, which exist independently of any government. These rights form the basis of his social contract theory, where the primary purpose of the state is to protect these pre-existing natural rights of its citizens.

The theory of natural rights is highly valued because it establishes a moral foundation for human dignity. By asserting that certain rights are fundamental and essential for human existence, it provides a standard against which the legitimacy of laws and government actions can be evaluated, protecting individuals from arbitrary state power.

Sir Frederick Pollock argued that the social contract theory acts as a critical tool against political deception. By grounding political authority in the consent of the governed rather than mystical or divine claims, the theory exposes the artificiality of illegitimate power structures, thereby stripping away the false pretenses often used by rulers to justify their dominance.

John Locke argued in his Second Treatise of Government that individuals acquire property rights by mixing their own labour with natural resources. By applying effort to the commons, a person removes the object from the state of nature and makes it their own, provided that enough and as good is left for others.

John Locke, in his 'Second Treatise of Government', argued that all individuals possess natural rights to life, liberty, and property. He believed that the primary purpose of government is to protect these rights, and if a government fails to do so, citizens have the right to revolt.

John Locke (1632–1704) was an English philosopher and physician. He is widely regarded as one of the most influential Enlightenment thinkers and is often called the 'Father of Liberalism.' His work significantly impacted the development of modern political theory, particularly regarding the concepts of natural rights, the social contract, and the separation of church and state, which were deeply rooted in the English political context of his time.

Critics of natural rights theory often argue that it presents rights as immutable, universal, and unchanging across different historical and cultural contexts. By framing rights as inherent to human nature rather than socially constructed, the theory is perceived as too static. This rigidity makes it difficult to adapt rights to evolving societal needs, technological advancements, or changing moral landscapes, leading to debates about the relevance of natural law in modern jurisprudence.

John Locke's seminal philosophical and political works, including 'Two Treatises of Government' and 'An Essay Concerning Human Understanding', were written and published during the late 17th century. This era was pivotal for the development of classical liberalism and the conceptualization of natural rights, which profoundly influenced subsequent political thought and the Enlightenment movement across Europe.

Locke posits that the primary purpose of entering into a social contract and forming a civil society is the preservation of property. In his terminology, 'property' encompasses life, liberty, and estate. The sovereign's legitimacy is derived from its ability to protect these rights against infringement, making the protection of property the central duty of any legitimate government.

Locke famously identified life, liberty, and property as the core natural rights inherent to all human beings. He argued that these rights exist prior to the formation of any government and that the primary purpose of the social contract is to protect these specific interests from infringement by others or by the state itself.
