Final answer:
In Platonic Idealism, the two elements that underpin its dualism are Form and Matter. Form represents the ideal concepts of things while Matter reflects the physical, observable world.
Step-by-step explanation:
The two elements that lie behind the dualism of Platonic idealism are Form and matter (Option A). In Platonic Idealism, forms represent the perfect, ideal concepts of things, while matter represents the physical world. These forms, according to Plato, are the true reality and are only comprehensible through the intellect. Matter, on the other hand, is the world we see, touch and interact with everyday, it is imperfect and constantly changing and can be perceived by our senses. This duality between form and matter underpins Platonic Idealism.
