Addendum: Unorthodox, Ontological Analogy Concerning Existence and Reality, is meant as an introduction to metaphysics; a word coined my Aristotle to express a reality other than the physical. We begin with a focus on consciousness, followed by an emphasis on ancient Greek wisdom. At times we will wander in rivulets to other topics along the way. The scope of this treatises is, as said and introduction to the ancient metaphysical wisdoms, but also a plunge into the fathomless ocean of esoterism. Our journey into the perception of reality is two-fold and is analogues to the dichotomy of Newtonian physics versus Quantum. In this work, the dichotomy is between perception and observation i.e. Duality and Oneness.
