EGO (Latin for I), the Self, in contrast with Alter (Lat. for other), another person, or NON-EGO, anything other than the self. Different views have been put forward as to the development of the consciousness of the self and of other selves. According to some, each of us has an immediate intuition both of his own self and of other selves. Others maintain that we each begin with an apprehension of his own self, and only arrive at an apprehension of other selves by a process of projection or "ejection" of our own self into other bodies, so to say. Others, again, hold that we get to know other selves and then discover each his own self by a process of interpretation based on our knowledge of others. The prevailing view among psychologists is that the two processes of knowing one's own self and of knowing other selves go on simultaneously, and that our knowledge of each is made richer by contrast with the other.
