Following such an argument we may come to the conclusion that others in my outer world are also in my inner world, through my perceptual processes. Ethics is related to others. How to live with or for others is a typical problem of ethics. Ethics is public. Care for and responsibility to others make us an inhabitant of the ethical world.
Ethics begins with the other.
So coordination of ethics and aesthetics requires consideration of others. Others are unavoidably tied to my inner and outer worlds. They are in my aesthetic and ethical life. I am not alone. Not a monad.
