Helpful definitions on Republicanism and Natural Law theory in Rousseau's context

On page 241, Rosenblatt, in her study Rousseau and Geneva, gives a couple of helpful definitions of republicanism and natural law theory.

Republicanism: "The republican tradition is based on the ideas of virtue and community and sees love of one's country and identification with the community as the essential conditions for a just political order.

Natural law theory: "The political doctrine of natural law is based on the notion of self-interest and sees the main role of the State as being the protection of private interests."
