Which option is not a characteristic of classical republicanism?

Classical republicanism primarily emphasizes the importance of the common good, shared governance, and active community involvement. These principles stress the role of citizens in participating in civic life and making decisions for the benefit of the community as a whole.

The notion of natural rights, while significant in political philosophy—particularly in the context of liberalism—does not align closely with classical republicanism's focus. Instead, classical republicanism is more concerned with civic responsibility and the collective wellbeing rather than individual rights that are inherent and pre-existing. Consequently, the concept of natural rights diverges from the central tenets of classical republicanism, making it the characteristic that does not fit within this framework.
