What are the essential differences between classical republicanism and natural rights philosophy?

Classical republicanism emphasizes the importance of civic virtue, common good, and the community's well-being, whereas natural rights philosophy prioritizes individual rights, autonomy, and the idea that certain rights are inherent and inalienable. Classical republicanism's focus is on the state's role in promoting the public good and maintaining social harmony, while natural rights philosophy stresses the limitations of government and the protection of individual liberties.
