Let us take a close look how the circle goes.
I say the absolute function order for INTP is
Ti Ne Ni Te Fi Se Si Fe
What is the criterium of a circle? The ends must compound.
I E I E I E I E .. the ends compound.
2. The blend of J - P
J P P J J P P J .. the ends compound.
3. The blend of T - F (n for neutral)
T n n T F n n F .. the ends compound.
4. The blend of N - S
n N N n n S S n .. the ends compound ..
Four dichotomies? Basically only one.
We have only a horizontal circle?
We have also a vertical circle.
Is the vertical circle idiomatic with the horizontal circle?
Is there an overall symmetric blend?
INTP is not the entirety. It is but a part of the entirety.
