Explanation
Platonism is the philosophical tradition that takes Plato's writings as its founding source and is unified by commitment to the existence of abstract, non-physical entities — paradigmatically the Forms — as more real than the changing physical world. Core Platonist commitments typically include: the existence of timeless universals or Forms, the soul's capacity to grasp them through reason, a hierarchical ordering of reality with the Good (or the One) at the summit, and the conviction that genuine knowledge concerns these eternal objects rather than transient appearances. Historically, Platonism unfolded through several phases: the Old Academy following Plato's death, Middle Platonism, and Neoplatonism (Plotinus, Porphyry, Proclus), which deeply shaped Christian, Jewish, and Islamic theology. In modern philosophy, 'mathematical Platonism' is the view that mathematical objects (numbers, sets, structures) exist independently of human minds and language — a position held by mathematicians like Gödel and Penrose. Platonism contrasts with [[aristotelianism]] (which locates forms within particulars), nominalism (which denies abstract objects), and empiricism (which grounds knowledge in sense experience). The tradition continues to influence debates about universals, the ontology of mathematics, ethics (moral realism), and the philosophy of mind.
