Answer: The feeling of disgust is a feeling of inconsistency with someone or something, when you feel that it is not yours.
Disgust arises when there is me and something outside of me, and this something is incompatible with me. Then I neglect it, disdain it, push it away. But when this “something” is inside of me, I feel the opposite, I love it.
It happens that a person, seemingly so squeaky clean, disdains anything and everything, but has no disgust with himself. This is an egoistic manifestation toward what is outside of me.
