what is the metaphysics of idealism
This is the view that the only reality is the ideal world. This would be the world of ideas. It is the view that there is no external reality composed of matter and energy. There are only ideas existing within minds. Idealism is the metaphysical view that associates reality to ideas in the mind rather than to material objects. It lays emphasis on the mental or spiritual components of experience, and renounces the notion of material existence.
