Pluralism (philosophy)
Pluralism is a term used in philosophy, meaning "doctrine of multiplicity", often used in opposition to monism ("doctrine of unity") and dualism ("doctrine of duality"). The term has different meanings in metaphysics and epistemology.
In metaphysics, pluralism is a doctrine that many basic substances make up reality, while monism holds existence to be a single substance, often either matter (materialism) or mind (idealism), and dualism believes two substances, such as matter and mind, to be necessary.
In epistemology, pluralism is the position that there is not one consistent set of truths about the world, but rather many. Often this is associated with pragmatism and conceptual and cultural relativism.
