According to pythagoreanism and later Plato, if the world is perfect and ruled by mathematical laws, the movement of the planets is harmonious, drawing perfect circles and producing music. In this way, the "Harmony of the Spheres" theory considers that planets themselves have an eternal and beautiful "soul". Thus, we want to show in our article that the modern conception of "planet" has lost its spiritual meaning under the guise of rationality. If science claims to be more objective than before, in fact it reduces evey being to a simple material object. By opposition, Edmund Husserl calls the "Lifeworld" (Lebenswelt) the natural perception humans have of their world. According to him, the Earth itself is not a planet, because it is the "Arch" where Humans live in accordance with a natural world. We will question that point of view through the filter of disenchantment.
