First, Logics' the main three decisive principles could be displayed so definitely.

  〇 Identity  P=P (just tautological truth as necessity)

 〇 No Contradiction  －(P ∧ ¬ P)

 〇 Law of Excluded Middle  P ∨  ¬ P

However, substantially upper two things could be difined so close pair,  because these two items must be rely on the absolute one stable factual truth, it must be focused at never changeable view.  In other words, these two things must be fixed truth as certainty.

Nevertheless, only the last item is just exceptional. Then, necessarily upper three set could be difined duality, or dualism as one set things. Upper two, 〇〇 set thing and another 〇.

But, we certainly can be awoken to that another one logical basis could be dragged there.
That must be as, being P nor not being P.  As 

                               －(P ∨ ¬ P)

Only upper concept must be so exceptional to upper duality dragging normally thought logic's basis. In other words, last just upper one is from the beginning,  just meaning that it must  never be dealt with P. Paraphrasing it, we could define that it is just "unfocused" as meaning of discription.

Originally false dechotomy must have hade been created with dualism, as logical habitual idea as duality at commonsense.
Paraphrasing these, we must have been accostomed with e.g. formalism and intuisionism as mathematics, or capitalism and communism as politics or so.
Eventaully, all these are just examples of dualim's usage in thought habit or conventional idea.

These very traditional ideas could be said either "black and white thinking", at the movie masterpiece, "Outrage Coda" directed by Takeshi Kitano described Nishino as gangster boss (Toshiyuki Nishida) at Kansai says to one another family member's next boss, "Which will you opt our fellow or enemy?" That must be just alternative and its idea's original fountain must be dualism.

If we accomplish the basis of logics switched to be at triplity as triplism here I introduce from original form, dualism as duality, very many contradictory deallocks could be solved or kind of melted so smoothly or kind of easily.

Orginally all logics' order must have been dependent on only "Logical big three principle with Identity , No-Contrasiction and Law of Excluded Middle.

However, Law of Excluded Middle is just uncertainty as another word of this proposional meaning for describing its essence. 

Then necessarily only using  －(P ∨ ¬ P)  at the case we use for dealing with our regarding contradictory condition, we could escape from the binding by dualism, thus it must complete our object triplism's set condition.
