The idea is that the schizoid condition has to do with an existence being easily disturbed or easily disturbable, which may correspond to the sense of having a "too thin ego". This echoes RD Laing's idea that the schizoid lacks some basic ontological security that the person needs in order to properly function in life.
Feel free to give your opinions or objections coz I'm still basically trying to figure these things out for myself, since alot of the different opinions on the thing seem to almost contradict each other (or maybe I'm just reading the wrong sources).
