At what Klein called the paranoid-schizoid position, there is a stark separation of the things the child loves (good, gratifying objects) and the things the child hates (bad, frustrating objects), "because everything is polarised into extremes of love and hate, just like what the baby seems to experience and young children are still very close to." Klein refers to the "good breast" and the "bad breast" as split mental entities, resulting from the way "these primitive states tend to deconstruct objects into 'good' and 'bad' bits (called 'part-objects')". The child sees the breasts as opposite in nature at different times, although they actually are the same, belonging to the same mother. As the child learns that people and objects can be good "and" bad at the same time, he or she progresses to the next phase, the depressive position, which "entails a steady, though painful, approximation towards the reality of oneself and others": integrating the splits and "being able to balance out ... are tasks that continue into early childhood and indeed are never completely finished."
