Rights and liberty refer to the entitlements and freedoms that individuals possess, allowing them to act, express themselves, and make choices without undue interference or oppression. These concepts are crucial in modern philosophy as they underscore the importance of individual autonomy, ethical considerations, and the moral framework within which societies function. Rights are often seen as legal entitlements, while liberty emphasizes the aspect of freedom from restraint, both contributing to the broader understanding of human dignity and justice.
