When the ancients set up their astrological chart for the the world itself, they took each of the planets according to their speed of motion and lined them up from the center of the Zodiac outwards. From this they derived the Thema Mundi, or theme of the world. However, the ascendant sign wasn't placed as Aries, the sign of warriors and might and official "first" sign, but as Cancer, the sign of love and nurturing and intuition, which incidentally makes quite a bit of sense theoretically considering the Moon is also the fastest planet and it is by light we see and not by the abstractions derived from light. The "tropical" zodiac could be considered to be derived from the Moon since it would not exist without harmonics and the Moon is the Sun's primary harmonic.
Yes, you had to read that to understand my next point. In shoutbox, another user proposed the "type types," so to speak, of extraversion as being SEE and of introversion as being LIE. Typing introversion itself as an extraverted type seems to be nonsense. I thought it would naturally be LII. So, if the prototypical types are actually SEE and LII, are our "conflictors" perhaps our optimal relationships rather than our duals?
