Plato’s Theory of The Soul in The Republic

The Republic of Plato has introduced a number of important and interesting concepts such as music, gender equality, political regime. For this reason, many philosophers and scholars still review the Republic regardless of age. But the most noticeable part is Plato's debate of the soul in the fourth book of the Republic. Since then Plato's definition has been used as a standard, this part is not only interesting, it is also important for all ongoing moral philosophy.

The theory of Plato's soul trilogy is the theory of mind that Plato, an ancient Greek philosopher advocated for his thesis "Republic", and is also the tank of the Fidelas tank. In the Republic, Plato insists that Ψυχή (thought) is made up of three parts: Logistik, Logic), Tumidé, Spirit. These three parts also correspond to three categories of society. Whether it is a city or an individual, δικαιοσύνη (dikaiosyne, justice) is declared as a state where each part fulfills its function without interfering with other people's functions. The function of creating and delighting joy. The function of λογιστικός is to gently control the love of learning. The function of θυμοειδές is to follow the direction of λογιστικός, intensely protecting the whole from intrusions and internal obstacles.

Plato is known for his three-dimensional soul (the soul) theory which is most thoroughly expressed in the Republic. The soul is at least logically divided into three parts, if not ontological: rational (sign), spiritual (thought), appetite or desire (facial expression). Rationality is responsible for rational thought and will dominate the most orderly soul. The spirit, like anger, is responsible for the feelings of anger. Appetite is responsible not only for natural appetite such as hunger, thirst, sexual desire, but also for appetite and desire for other appetite. According to Plato, why are these three separate? Discussion on the difference between the three parts of the soul depends on the principle of contradiction
