Plato’s Philosophy: Exploring the World of Ideas and the Sensible World
Plato’s Theory of Ideas
Plato explains reality and phenomena through his Theory of Ideas. This theory encompasses two worlds: the sensible world and the world of Ideas.
The Sensible World
We perceive the sensible world through our senses. It consists of things constantly changing, subject to time and space. These things are material, changing, perishable, imperfect, and individual.
The World of Ideas
We perceive the world of Ideas through intelligence and reason. It consists of eternal, immutable ideas with logical and metaphysical aspects. These ideas are immaterial, unchanging, perennial, perfect, and universal.
Plato prioritizes the world of Ideas, viewing the sensible world as an imperfect copy. He establishes a hierarchy for both worlds. The world of Ideas is headed by goodness and beauty, followed by justice, courage, order, mathematical concepts, and finally, ideas of sensible things.
The relationship between the two worlds involves copying and participation through the hierarchy of Ideas.
The purpose of everything is to seek perfection and its own good (the supreme Idea). For Plato, the supreme Idea is knowledge of the world of Ideas, and the goal of humans is to know the Good within this world. Knowing the Good leads to knowing everything.

Plato’s Theory of Recollection
Plato’s theory of “recollection” (anamnesis) posits that remembering is knowing.
Humans are composed of two realities: the material body and the immaterial soul. The soul belongs to the world of Ideas, while the body belongs to the sensible world. This makes Plato’s theory dualistic.
The soul is immortal, while the body is mortal and subject to change. A good soul remains closer to the world of Ideas, while a bad soul falls into the sensible world. Upon death, the soul of the good ascends to the world of Ideas, while the soul of the bad fluctuates around it.
The soul knows the world of Ideas due to its proximity. Upon falling into a body, the soul forgets this knowledge. Sensory experiences stimulate the soul’s memory, prompting recollection.
Plato believed humans cannot fully remember absolute reality until after death, when the soul is freed from the body. The body acts as a prison for the soul, hindering true knowledge. For Plato, only physical death exists, as the soul lives on.
Knowledge, for Plato, is the recollection of truth (ideas). True knowledge involves approaching and contemplating Ideas.
Two Methods of Knowledge
- Experience: Used in the sensible world, focusing on images and sensible things. Knowledge types include imagination and belief.
- Dialectic: Used in the world of Ideas, focusing on mathematical objects and ideas. Knowledge types include discursive knowledge and intelligence.
In the dialectical method, only the brightest minds achieve knowledge of the Ideas. Recollection is challenging, and not all humans are capable of it. The dialectical method ascends towards Ideas, revealing their hierarchical relationship culminating in the Idea of the Good.
Plato’s Anthropological Theory
Plato’s theory is dualistic, viewing humans as composed of body and soul.
- Soul: Immaterial, immortal, originates from the world of Ideas, vital principle of the body, independent, houses intelligence.
- Body: Material, mortal, sensible, imperfect, dependent on the soul, belongs to the sensible world, responsible for evil and ignorance.
Plato values the soul and undervalues the body, viewing the body as a prison for the soul. The aim of humans is to cleanse the soul from the body’s negative effects. This dualistic view allows humans to know the world of Ideas through senses and experiences that trigger memory.
Plato’s Political Theory
Plato correlates the soul with the structure of the polis (state). He believed a just state mirrors a just soul. He thought isolated individuals cannot achieve justice. Platonic ethics informs his politics, as only a just state can educate just individuals.
Organization of the Ideal Polis
After Socrates’ death and the rule of the Thirty Tyrants, Plato abandoned active politics. He sought justice within the state, believing no prior state had contributed to a just society. In his ideal polis, each individual fulfills their best-suited function, with philosophers as rulers.
