There are many people who think the basic problem of humanity is our ego...that we are ego centered/egotistical creatures. But isn't our ego what differ us from animals? Animals are not aware of their existence, they are not aware of their ownselves, so they don't have ego.
Because of our ego, we're not only aware of our existence, but it also makes us desire, to have power over others, appreciation of our accomplishments, we want to be noticed, we want to know who we are, we are aware of our psychical needs, we are aware of our wisdom, or power and so we use all the characteristics to build up our egos.
So I wonder, do you think awareness of our ego comes with inteligence? What if we would be inteligent as we are, but wouldn't have egos? What kind of effect would it have on human nature?
