Dr. Walden introduces Ecstatic Naturalism, a metaphysics similar to Idealism but less committed to mind as we know it. While proposing that the archetypes—an eminently mental concept—serve as conduits to a fundamental layer of reality that is both transcendent and immanent in the so-called physical world and the human mind, it remains open to the possibility that such a layer may transcend our very understanding of what mind is.
