What is the ideal state? This question has sparked debate since the very formation of organized political society. In Plato's Republic, Plato seeks to define justice and in doing so seeks to explain the ideal just state. In Plato's explanation of an ideal state, there is an extreme emphasis on unity and harmony. The reason why unity and harmony are so important to Plato is because they are responsible for holding Plato's ideal state together and protecting it from tyranny. Plato extensively explains the structure that links the individual soul with the ideal political society. Without unity and harmony, an aristocracy would eventually decay into a democracy and, according to Plato, sooner or later a tyrant would rule the state. To understand how unity and harmony bind the ideal state together, it is necessary to first understand the coloring of unity with justice. Justice simply defined, according to Plato, is specialization. Every person doing their job is what justice entails. However, this definition of justice leads to something broader within the individual and the state. According to Plato, "... we must force these our Guardians and Auxiliaries to second our efforts; and they, and all the others with them, must be induced to become perfect masters each of their own art. In this way, as a community grows until it becomes a well-ordered whole, the different classes can be granted the measure of happiness permitted by their nature" (P, p. 111). The theory of justice as specialization leads to the happiness of the whole. Just as Plato finishes explaining the life proposal of a Guardian, Adeimantus asks himself "how would you respond to the objection that you don't make these people particularly happy" (.... .. middle of the paper ...... state. Nell Plato's argument for the ideal state, the fundamental ties that hold his republic together are unity and harmony. He explains how the just state is held together by the unity of each individual in each social class and the. harmony between all three social classes. Plato explains how the ideal state must have citizens united in their goals. At the same time, it is the happiness of the whole that maintains the ideal. Plato argues that there must be harmony within the individual souls that make up the state. The lack of unity and harmony leads to despotism through anarchy which ultimately arises within a democracy. Plato makes a clear argument, through The Republic . that without the unity and harmony of the individual and the State there can be no order and therefore there can be no ideal state.
