A novel approach to classical elements as in Fire, Air, Water, Earth, Aether or the trigrams of the Chinese I Ching-based on immediate experience of space and time. Inspired by Kant's and Schopenhauer's takes on what exists a priori, "elements" are defined in terms of in/out and rest/move and are shown to resemble known elements to an astonishing degree, suggesting furthermore novel takes on seeing the world with potential to unify various contemporary views as in science, astrology, New Age, and more, into a coherent view that is at least qualitatively compatible with them all. This thin pocket book provides the core content of the website exactphilosophy.net preceded by a short introduction. New findings after the first edition turned this akin to Kant's Prolegomena, or rather already the metaphysics it announced. Take this book out into nature and contemplate it at a calm place far from contemporary noise.
