There is an important difference between self-perception and self-definition.

POF 5-7 Self Perception, Self Definition
The perception of myself reveals to me a number of qualities which I combine into my personality as a whole, just as I combine the qualities yellow, metallic, hard, etc., in the unity "gold." The perception of myself does not take me beyond the sphere of what belongs to me.

This perceiving of myself must be distinguished from determining myself by means of thinking. Just as, by means of thinking, I fit any single external perception into the whole world context, so by means of thinking I integrate into the world process the percepts I have made of myself.

My self-perception confines me within certain limits, but my thinking is not concerned with these limits. In this sense I am a two-sided being. I am enclosed within the sphere which I perceive as that of my personality, but I am also the bearer of an activity which, from a higher sphere, defines my limited existence.

How do you perceive and define yourself? How do you perceive and define others?
