1. Definition of SPs
First, how should the SPs be defined? A straightforward one should go like “parts of personality holding anger or destructiveness.” It also has a connotation of shadowy figures behind the scence who pull strings. Another important nature is its relative anonymity. They are often referred to as “it”, “unknown” or “anonymous”. They sometimes have an implication that they are not supposed to be born or are not worthy of existing in this world. Its appearance is typically ephemeral, passing and without any attempt of contacting other personalities or people outside. To put these characteristic together, SPs should be formulated more in detail; “these are parts of personalities which hold anger and destructiveness, which tend to appear only temporarily in a rather critical occasions.”
