When we feel maltreated by other people who do not know almost anything about us, perhaps they do know us entirely.
For instance, those who lead bad governments know everything about the individuals when they see them as replaceable items into the wide society; because it is difficult to say that an individual is more than one item, as long as he is included into a numerical group.
The strangers who hurt us physically or morally also know about us that sometimes we hang entirely on our bodies or feelings.
We cannot fight with such attacks by showing that we are something else than the whole of us which they affected. A better defense is to understand that such wholes are ever regenerative. Even the bad injured body finds its entirety again when it becomes a dead body. For a while, the dead body represents us entirely defying the causes of death which meant to hurt us.
