What is Platonic realism?

Platonic realism, also known as the Theory of Forms, is a philosophical theory credited to Plato proposing that the physical world is less real than timeless, abstract essences called Forms. These Forms exist independently of human minds and constitute the basis of reality. While influential as a classical solution to the problem of universals, the concept remains a subject of ongoing philosophical debate.

What we know

• The Theory of Forms, or Platonic realism, is a major concept in metaphysics credited to the Classical Greek philosopher Plato. [3]
• Philosophical realism, which encompasses positions like Platonic realism, views certain kinds of things as having a mind-independent existence. [3, 5]
• Plato's theory asserts that certain abstract ideas are literally real and exist outside of human minds. [3]
• Plato describes these entities through characters in his dialogues, such as Socrates, who sometimes suggest Forms are the only objects providing true knowledge. [3]

Still open

• Characters in Plato's dialogues sometimes suggest Forms are the only objects of study that provide knowledge, but at other times contest the very existence of the Forms.
