Self-representation and understanding of the broader world.
We may know more about the outside world than we know about ourselves, we may be able to explain more about what the facts are than what the feelings are, we may not understand why some things do not go our way simply because we have never communicated properly to others what we really want. We may, very often, generalize a lot of things using stereotypes not because we do not care but because we simply cannot interact with the other side of the world. We as humans have such complex language systems and constructions compared to animals and so we have to really take the advantages of this human development and respect it as another great joy to see, hear, experience and express ourselves in this world.
