Contemporary society has specific feature that anybody could be prersent to be joyful at cooperating social activity even if internally each one has dark mind or sulky emotion to any other one in society, anybody has mission feeling to be a citizen of no resistance to anything in  terms society, then once upon a time, philosopher and author Jean-Paul Sartre discribed at L'Être et le néant, Deuxième partie : L'être pour soi as we can interpret felsehood to myself, in terms of social obligatory mind pressure, then anybody is pretending to be happy at any work, but this posture could drag so frustrating in each mind, then domestic violence could be drawn at home so personally and these stoically suppressed mentalites consequently drag either domestic terrorism, and that example could be easily discovered at many countries at now. 

Principly, these pressures as suppression to each "myself" so autonomously spontaneously mobilized act in pretence means interlocking reality as we are obliged to be obedient at socially promised loyalty, and at each spot of social activity, we sufficiently get tangiblity to own sensitivity as each social functional interlocking and make each oneself a part of society as gear or cog in the machine, then at these occasions we must be conscious the ∀ at each site of our working reality.  Its nature is never ∃. That thing was already interpreted by Heidegger with his term of Seinsvergessenheit, oblibion of being.

Then we can have some supposition like next.

If we define each of us  as a, and our society could be A, 

￢∃= （A∀∋ a）

Nevertheless, a 's set could never be ∃.

then, 

∃≠ A∀

Necessarily,

∃≠∀

Nevertheless, we all could be apt to be 

（A∀∋ a）

Thereby, we all are at survival of (∃≠∀).

And consequently, we have nature to be (a ∈ A∀).

At awareness of us makes us know contradiction, contraposition or any kind of logical symbols.

Necessarily our social interlocking must mean,

￢∃= A∀

（to be continued)

Additional note; However, I could never acquire all logically intepreted formula of being's impossibility around socially interlocking of our reality.
