Answer:
Double consciousness is a term that DuBois created to mark the inner life of African-Americans. They have two views of themselves - first one when they look themselves through their own eyes, principles, views, ideas etc; the other is when they perceive themselves through the eyes of all-white society (one person or whole society). So it was hard for them to develop individuality, real self, self-esteem This term is coming from early the end of 19th century, but unfortunately it is still relevant.
Today we can see this, except in multicultural societies where racism still has not disappeared, in patriarchal societies where women are in a subordinate position. Again, there is a two-sided perception of themselves - how they see themselves and how men around them see them.
