Plato's Philosophy: Society, Knowledge, and the Ideal State

Platonic Political Theory: The Ideal State

In The Republic, Plato outlined his conception of the social and political ideal. Based on a critique of unsatisfactory definitions of justice, Plato proposes an analysis of what constitutes fairness in both the individual and the city-state, aiming to achieve a satisfactory definition of justice. He argues that the city-state emerges to satisfy humanity's complex needs, as no individual can be self-sufficient. The division of labor is thus the basis of all civilization. Basic human needs—food, housing, and clothing—necessitate the existence of farmers and artisans. Trade and money then emerge, along with other societal needs. This context frames the central focus of The Republic: the political ideal and the appropriate education for different societal roles.

There are two main theses of Platonic political theory:

• The city government should be an art based on true knowledge.
• Society is a mutual satisfaction of needs among its members, whose skills complement each other.

Plato's Division of Society: Three Classes

Plato's approach leads to a structured organization of society, divided into three distinct groups:

• Producers (farmers, artisans, and merchants)
• Guardian-Warriors
• Rulers-Philosophers

For Plato, a happy city is one in which each individual fulfills their duties according to the ideal order. The task of the ruling class is to ensure this order is maintained, that each individual occupies the position corresponding to their natural aptitude, and receives the proper education for their role in society.

Platonic Theory of Knowledge: Reality and Forms

Plato's theory of knowledge is intrinsically linked to his conception of two distinct orders of reality. Consequently, he posits two types of knowledge. Plato believed that sensory impressions, being constantly changing, cannot provide us with true objects of knowledge. Moreover, in opposition to the subjectivism of the Sophists, Plato sought to prove that true knowledge (science) is not reducible to mere sensation. While sensory appearances are changing and subjective, the objects apprehended by intelligence possess unchanging and objective significance. The knowledge of these realities is derived from thought. This is what he means when he states that these realities are intelligible. This statement also implies that these ideals (or Forms) are concepts or realities that exist independently of human thought and are only accessible through intellectual contemplation.

In the Myth of the Winged Chariot, Plato argues that the soul, prior to its embodiment, has seen the World of Forms (Ideas). For various reasons, the soul has fallen from this world and reached its current state, embodied in a physical body. This dramatic change of situation, and its confinement within a body, has caused the soul to forget much of that initial and crucial experience. However, this forgetting is neither complete nor definitive. Through contact with and knowledge of various sensory experiences, the soul is reminded of aspects of what it perceived before incarnation: the true reality. Plato uses this theory of reminiscence, along with arguments for the immortality of the soul, in his dialogue Phaedo, thereby linking three key elements of his philosophical system: human nature, immortality, and knowledge.
