Iamblichus says of the dyad (2):
"For when the monad manifests unification, the dyad steals in and manifests separation."1
It is also called,
"Movement, Daring, and Impulse"2 The dyad symbolizes that which causes the monad (1) to extend itself from its state of "potential" to the manifestation of form found in the triad.
Iamblichus writes,
"And they say the name 'dyad' is suited to the moon, both because it admits of more settings than any of the other planets, and because the moon is halved or divided into two: for it is said to be cut into half or into two."3
The lunar nature of the dyad gives it a
phlegmatic temperament.
The sword, the classical emblem of the
choleric temperament, calls to mind quick reactiveness (hot) coupled with the ability to endure (dry).
The
Deuce of Swords then shows a mixed temperament of
choleric-phlegmatic, which have no common qualities, and could be seen, coupled with the nature of the dyad, to represent the ability to successfully merge extraneous unrelated things, the ability to strike a delicate truce (balance) between things, or to have an impulse to challenge a seemingly unattainable goal. Mixed temperaments however, in my experience, tend to be problematic, with the
Deuce of Swords showing a possible inclination toward disjointedness, difficult reconciliations, bouncing between extremes, separations due to lack of commonality, irreconcilable dichotomies, and not being congruent with ones true desires.
