This document discusses the views of philosophers Immanuel Kant and Arthur Schopenhauer and how they relate to Divine Principle teachings. It summarizes Kant's view that cognition requires both external sensations and internal subjective forms of intuition and thought. It also describes Schopenhauer's view of the world as the product of a blind and malignant metaphysical will, which aligns with Divine Principle's description of the Fall. The document analyzes how these philosophers approached internal and external pursuits of human nature, pioneering an "Abel-type view of life" that guided people to seek God in a deeper way.
