What is Cicero's concept of natural law?
True law, the rectissima ratio, is right reason, which is in accordance with nature. It is of universal application, unchanging, and eternal. It commands what duty requires, and prohibits what is wrong. This natural law is not merely a human construct but is instilled in us by nature, and our duty is to live in accordance with it. To disregard it is to deny our own nature and to invite chaos. This principle provides a foundation for justice and good governance.
