Relations of Duality between Aspects
Some of these may sound pretty crazy, but they seem to work out. In fact, I believe many of our metaphors arise chiefly from these relations.
Quake: +Ti breaking off from -Ti, rupturing structure and creating an impulse (+Fe) which is rejected by another structure (-Fe)
Revolt: +Ni refuses to play along with -Ni, creating a rouge element which clashes +Se against -Se.
Fluid: +Fi fuses with -Fi, allowing -Te to accept incoming +Te work freely.
The underlying theme appears to be, that if an aspect clashes with another then its dual aspect will clash with its own counterpart.
