The theoretical justification of natural rights examines the philosophical foundations and ethical principles that support the existence and applicability of these rights. People have some rights simply by being human, and neither groups nor governments may bestow them upon them, according to the idea of natural rights. It also provides a concise overview of the theories that support natural rights, including those that rely on moral intuition, human nature, and the Social Contract. The moral intuition approach maintains that natural rights are self-evident and universally accepted since they are based on our innate sense of right and wrong. It claims that certain inherent human rights are required for human flourishing and well-being. Based on the intrinsic qualities and needs of people, the human nature perspective defends natural rights. It argues that some rights, such as the right to life, liberty, and property, are derived from basic human attributes and abilities. According to the Social Contract theory, a hypothetical agreement among members of a community serves as the foundation for natural rights. It proposes that people voluntarily create a Social Contract to set up a governing body that upholds and defends their fundamental rights. These theoretical defenses offer frameworks for comprehending the nature, significance, and defense of natural rights. They emphasize on these rights’ intrinsic and universal nature, the value of human dignity, and the idea of inalienability. Individuals can live dignified lives by recognizing and upholding their natural rights.
