Platonism

Platonism is the philosophical tradition founded on the ideas of Plato, centered on the theory of Forms — the view that abstract, perfect Forms are the truest reality.

Originating in Plato's Academy, Platonism holds that the physical world is an imperfect reflection of eternal, non-physical Forms, and has profoundly shaped metaphysics, ethics and theology.

Platonism is among the most influential traditions in the history of thought. Rooted in the dialogues of Plato — and dramatized through his teacher Socrates — it argues that beyond the changing physical world lies a realm of perfect, eternal Forms.

This idea echoed through Neoplatonism, Christian theology and Renaissance humanism, making Platonism a foundation stone of Western metaphysics.
