Plato's theory of justice and the ideal state form the cornerstone of his political philosophy. He envisions a society led by philosopher-kings, with a strict class system and communal living for the guardian class. This utopian vision aims to create a just and harmonious society.

Plato's ideas are rooted in his theory of forms, which posits a higher realm of perfect, unchanging ideals. This concept is illustrated through the famous allegory of the cave, highlighting the philosopher's role in guiding others towards true knowledge and justice.
