“We can be sure that the fifth element (idea) was immaterial for Plato and Aristotle, who used the term aether. The fifth element (Latin: quinta esentia) differs from the other four elements (Earth, Water, Fire, and Air). When we look at aether, from the perspective of our philosophy, as the main principle before the formation of the world, as a potential (in posse), during its actualization (in esse), and as the underlying Being or reality of all the existence, then this term can be equated with God or, conditionally, with the Universal Mind. A posse ad esse is the transformation from the potential of the Universal Mind to its actualization as the Universe.”
