A Twenty-Billion-Year Old Secret? All major philosophical theories of the past four thousand years start with a particular interpretation of human reality. But do these often conflicting perspectives help us understand nature? How can complexity in and around us be explained when we take the human body and soul as the starting point? Why do we turn our back on twenty billion years of history? "Winter Letters" is a radically different approach to understanding the reality of human nature and behavior. The author searches his own past for events that had a lasting impact and from that discovers a starting point for humanity much further back -- back at the very beginning. You are invited to sit at the center of a spiral that originates way before matter, movement, and change gave rise to the first sign of life. The spiral starts with the elements of matter plus their related natural and "primal" forces. What followed are the determinants for all things we claim to know -- personal, societal, political, and religious. It's a creative way of seeing what is behind every interaction at all levels of atomic, cellular, and human. But we have so far largely missed the point of these interactions by either ignoring or misunderstanding their roots and interdependencies. "Winter Letters" connects the basic phenomena of science and humanity -- right from the very start.
