Abstract
The sequence from ideal state to tyran I ny contained in Books VIII-IX of the Republic constitutes neither history nor philosophy of history, but rather completes Plato's overall theory of politics, dealing, like every theoretical science, with simplified or pure cases, and narrated purely for dramatic effort. Popper's view that Plato was fundamentally an historicist is incorrect. Plato makes no straightforward comments on philosophy of history. Perhaps, like many Greeks, he surveyed history pessimistically, but he did not propound an iron law of decay. As a social scientist Plato held that there are laws of political change without supposing the course of history is unalterably fixed
