Tyranny, in western political philosophy, is the primary subject of inquiry. Western political philosophy developed remedies for the evil of tyranny because it is considered unnatural. By the time of John Locke, there was a consensus developed in Europe that living under tyranny is the same as living in the state of nature. The natural law theory lays the foundation for law, such as positive law, under the premise that no law can violate natural law. This dictum laid the foundation (...) for republicanism in the West to counterbalance tyranny. The mechanism for such endeavor is the separation of law from authority to the degree that law is above the authority. My research is to trace the similar thought, if any, in the Iranian context beginning with its ancient time. (shrink)
