Out of the first distinction comes the second distinction; the distinction between Soft (Blue: RGB 00F) and Hard (Yellow: RGB FF0). I call this Substance. The Moving and the Moved differ in the World of the Living (Soft) and the World of the physical (Hard). This is how the four Tetrarchs come about: the Sun (Moving-Soft), Uranus (Moving-Hard), the Moon (Moved-Soft) and Saturn (Moved-Hard).
