Step-by-step explanation:
Plato's Doctrine of Ideas, also known as the Theory of Forms, states that there is a higher realm of eternal forms or ideas that are perceived through the mind. According to Plato, these forms are more real and perfect than the physical objects we experience in the world. They exist independently and serve as the true essence or nature of things. Plato believed that knowledge and virtue come from understanding these forms through contemplation and rational inquiry, rather than relying solely on sensory perception.
