The nature of life is at the center of national debate. Are we mere material mechanisms? Or is life a vast nonphysical dimension that organizes matter? Does God exist? The issue is not academic. The question defines the nature of human reality. What are the limits of consciousness? Do our memories exist in our brains or in the vastness of time? The Vital Dimension examines the thoughts of eminent scientists such as the Nobel Prize Winners Erwin Schrödinger, Werner Heisenberg and Sir John Eccles who concluded that life is a mysterious force unknown to modern science. The Vital Dimension embraces René Descartes' admonition, "Doubt all that can be doubted!" to look beyond the rigid preconceptions of mechanistic biology and construct a truly radical theory of life. More than mere speculation, the weight of scientific evidence points to the fact that the modern, material view of reality is on the verge of a profound revolution. The world stands at the threshold to the Vital Dimension. Dare we open the door?
