“Self” and “Other”
A related concept is the idea of the “Other” (for example, the “Oriental Other”).
In literature and in life, “the Other” is someone whose very different nature helps you define yours.
In narratives that range from ancient myths to modern film, encounter with “the Other” is a trigger for human passages and key experiences.
But “the Other” may be slighted in the process, as an object defined only in terms of the Self’s experience.
“The Other” is often not seen (or portrayed) as a whole person, someone who experiences and feels and has a full existence.
