Before you is one of the greatest works of the ancient Greek thinker Plato, written in 360 BC, which at this time has not lost its extreme relevance. The essay is built on the principle of conversations devoted to the problems of building an ideal state. The dialogue also contains systematics and a brief critical analysis of six forms of the state, placed by the author sequentially - from best to worst: monarchy, aristocracy, timocracy, oligarchy, democracy and tyranny.
