In this perspective ‘Abd al-Latif introduces Plato’s political philosophy. Since the perfection of the soul is possible only in a city where justice reigns, Plato starts from analysis of what justice is and how it ought to be. Then Plato examines the cities which deviate from the good ways of life and from the philosophical virtues. In the virtuous city, man must be educated in the knowledge of the divine and natural beings and in following a virtuous way of life. Human perfection is achieved by the man who combines the theoretical, the political and the practical sciences. He will rule and will possess the ability to conduct a scientific investigation of justice and the other virtues and to form the character of the youth and the multitude. He will be able to correct wrong opinions and to cure every rank of his society with knowledge. The ruler will be the one who has achieved human perfection at its utmost.
