As Western reason is based on a denial of the fundamental law of the Universe—as the Cosmic Equation in Panosophy—we need a life-enhancing art and science of reason to explain what is causing scientists and technologists to drive the pace of scientific discovery and technological development at unprecedented exponential rates of acceleration.
Our cultural conditioning is a major inhibitor to understanding what is causing us to behave in the ignorant ways that we do. But perhaps at this late stage in human evolution, Life could still lead us into the Age of Light, where Self-reflective Intelligence could show us the way Home to the Divine, as our Immortal Ground of Being.
