Impartiality, freedom from bias or preconception.

The non-taking—of position, perspective, or preference.

The word unbiased often implies moral effort—a willful suppression of opinion.

But structurally, Un-vor-eingenommen-heit describes 

a state before any form is taken.Before in-taking begins.
Before the self assumes a vantage point.
It is not neutrality as a concept—it is the absence of grasping.True Unbiasedness is not achieved.
It is simply what remains when nothing is held.
