Plato's Theory of Forms

Theory of Forms

• Plato believed true reality exists beyond our perceptions of the world.
• The world of forms contains the perfect ideal of a thing.
• We perceive the shadows of forms in our physical world.
• We rely on our senses to understand the world but it is constantly changing.
• The real world is outside our physical world and is unchanging and eternal.
• The real world is the world of ideas, not senses, where perfect forms exist.
• The world of being is fundamental reality and ultimate reality exists beyond our physical world.
• The world of becoming is the world of our senses.
• Plato believed true reality is composed of pure forms or essences.
• The theory of forms envisions a universal world outside time and space, with universal forms of beauty, justice, and courage.
• Forms or universals are eternal, unchanging, and necessary.
• The visible world of sight and sounds we inhabit is distinct from the intelligible world of form that stands above it and gives it meaning.

Aristotle - Form & Matter

• Aristotle believed that the form of a thing was not an abstract entity, but common to all things.
• All substances are composed of matter.
• Matter is what a thing is made of.
• Form is what a thing is made to be.
• According to Aristotle, the form of a human is the soul.

Aristotle - Four Causes

• Aristotle believed scientific knowledge comes from experience.
• All things have four causes.
• Material cause is what the matter is made of.

• Efficient cause is the agent that caused it to be.
• Final cause is the purpose for which it exists.

Plato’s Allegory of the Cave

• The cave represents our world of perception.
• Prisoners represent people trapped in their beliefs and the world of shadows.
• Shadows represent the illusions we perceive as reality.
• The sun/light represents true knowledge and enlightenment.
• Puppeteers represent those who control our perceptions.
• Freed prisoners symbolize those who seek true knowledge.
