Barrier against cognizance: Most humans cannot look at themselves from an objective point of view. This is not limited to the heart but also occurs with the physical body.
Humans cannot see themselves. No, more correctly, the impartiality to look upon "oneself without falsehoods" and accept it is rare.
Because humans possess wisdom, they are able to turn only the convenient aspects of the reality in front of their eyes into the truth. It's not just being selective about what information they accept; there is also unconsciously fabricating or modifying information.
Passionlip's barrier against cognizance is of the highest order. She does not comprehend the form of her own two hands. Her "brain" averts its eyes from her own ugly appearance, and within her mind, she is converted into an exceedingly normal girl. To her, her claws only appear as "normal."
Because of this, Lip does not understand the reason "why everyone is afraid of me." Without realizing the reason is her own body's ugliness, she would simply tilt her head if you were to point it out to her.
"Why are you telling such a lie?" "Are you lying to bully me again?"
In relation to her barrier against cognizance regarding her giant claws, Passionlip is a perfect victim. Though a barrier to cognizance is something born from trying to escape, there is neither deceit nor lies in her heart.
Everyone finds it difficult to face their ugly qualities. When one looks in the mirror, is the brain properly observing the image of oneself reflected there?
