Plato’s Philosophy: Soul, Ethics, Politics, and Education
Anthropology: Plato’s Dualism
Plato presents a dualism of man, mirroring the duality of the world. Just as the world of ideas takes precedence over the material world, the soul, in Greek philosophy, takes precedence over the body. Philosophers have long pondered the nature of the soul. According to Plato, the soul possesses the features of the world of ideas: it is immortal, eternal, unborn, and unknowable through the senses. Conversely, the body is material, impure, sensitive, and full of passions, appetites, desires, and instincts. It imprisons and corrupts the soul.
Ways to View the Soul
- Principle of Life: This corresponds to Aristotle’s view.
- Principle of Rational Knowledge: This is what enables us to reflect and to know all ideas through reason. This distinguishes man from animals and corresponds to Plato’s view.
Functions of the Soul
Plato, in his dialogue Phaedrus, outlines three functions of the soul, understood not as material parts but as aspects of its operation:
- Rational Function (Logos): Represented as the charioteer, this is the noble part that regulates the higher functions of man. It is located in the brain.
- Irascible Function (Thymos): The spirited soul, symbolized by a good and beautiful horse, represents courage and regulates noble passions. It is located in the chest.
- Appetitive Function (Epithymia): Symbolized by a bad and ugly horse, this represents base desires, passions, and vegetative desires. It is located in the abdomen.
Ethical Theory
Plato bases his ethics on the world of ideas. The Ideas of Justice and Good underlie the measure to discern good from bad. Plato believes that moral concepts should be established rationally, and finding their definition is a must for every ethical system. Plato’s ethics are eudemonistic because they address the question of the Supreme Good. Dialectic and virtue lead a man to the contemplation of ideas, which is the highest good. The highest good is the happiness of man. It is neither pure sensitive pleasure (unstable and inadequate) nor pure wisdom but a mixture, just as man is a mixture of a rational soul and a material body. This mixture is formed by a range of goods, according to the standard triple measure of truth and beauty, which are the essential elements of the Good. This scale includes:
- Nature and classification of virtues
- Knowledge
- Soul purification
- Harmony
Political Theory
For the Greeks, politics and ethics are not separate entities. Plato postulated the ideal political state in his work, The Republic. Man is not only an individual but also a citizen, and it is within the polis that he acquires the ethical virtues characteristic of every honest citizen. The central theme of The Republic is justice. Plato explains how the state should be ruled, presenting a political utopia where the government belongs to the philosophers. Men are not independent of each other but need cooperation in the production of all that is necessary for life. No man is sufficient unto himself but needs many things. The first is the provision of food. Everyone needs others; hence, we partner in cities. The original purpose of the city is the division of labor, goods production, and exchange. The ultimate goal of the city is the happiness of its citizens. The most important thing for leaders is the good of their subjects, justice, and peace. The common interest comes before private interest.
Axiological Theory (Theory of Education)
The role of governments in the smooth running of the city is crucial, as they are the absolute arbiters of political life. Therefore, the government is left to the best, the most gifted, and the most prepared. It is a form of government based on brainpower and scientific training. Hence the great importance of education. Education has inherent difficulty, requiring effort and a break with apparent safety. Thus, Plato establishes a system of education, from the least equipped to the most, so that each person may play the role for which they are prepared.
