The Republic is a philosophical dialogue work written by the ancient Greek philosopher Plato (427- 347 BC). This book mainly discusses the construction, governance and justice of Plato's ideal country, with the theme of state management.

Plato's Republic is his masterpiece, involving politics, education, ethics, philosophy and many other fields. His thought is broad and profound, which almost represents the whole Greek culture. From 20 15 to 1 1, The Republic was rated as one of the 20 most influential academic books in British Academic Book Week.

Plato took the story as the theme in the Republic, telling that Socrates went to Bells to pray for God and was invited home by Paramark on his way home. The two sides talked about this. The argument between them exposed the philosophy, politics, art and education thoughts of the slave-owning class from various angles. Socrates in the story is fictitious and pretentious, and is actually the spokesman of Plato.

This paper discusses justice with people through Socrates' mouth, analyzes the interoperability between individual justice and polis justice, and systematically expounds the concept of justice. Plato designed and looked forward to the blueprint of his ideal country, and proposed that justice can only be truly realized in the "ideal country".

The Republic consists of ten volumes. The first and second volumes discuss the issue of justice. Because in Plato's thought, the establishment of a country is to achieve justice, so these two chapters summarize the main idea of the book.

The second half of the second volume to the third volume discusses the education of defending the country, which is also the primary education of the rulers. The fourth volume discusses the effectiveness and leadership of education, and also talks about the significance of temperance, courage, wisdom and justice. The fifth volume discusses preschool education and women's education. The sixth and seventh volumes discuss the cultivation of philosophers, that is, the advanced education of rulers. The tenth volume is about art.
