Object, subject; simject.

I would like to propose the simulject, or simject for consistency, from Latin simul (“together, at the same time”), as the parallax positionality of subject and object.

This is an impossible concept, because it proposes a positionality that fundamentally precedes or exceeds concepts (which requires the separation of subject and object), however references a more fundamental synchronistic and integral state of reality.  

from sub- ‘under’ + jacere ‘throw’

ob- ‘in the way of’ + jacere ‘to throw’

To be both under, and in the way, of is to be a black hole.
