Answer: 3 Dualism
Explanation: Plato is commonly associated with the metaphysical theory of Dualism. Dualism posits that there are two fundamental substances or aspects to reality: the physical/material and the non-physical/immaterial. In Plato's philosophy, this is often expressed in terms of the division between the material world, which is perceived through the senses and is constantly changing (the realm of Becoming), and the world of Forms or Ideas, which is eternal, immutable, and grasped through reason or intellect (the realm of Being). Plato's theory of Forms suggests that the physical world is a mere reflection or imperfect copy of the realm of Forms, which contains the true essence or ideal forms of everything.
