I offer here John Steiner’s brief characterisations of the two positions which have come to be seen as the basic modes of feeling between which people oscillate: ‘As a brief summary: in the paranoid-schizoid position anxieties of a primitive nature threaten the immature ego and lead to a mobilisation of primitive defences. Splitting, idealisation and projective identification operate to create rudimentary structures made up of idealised good objects kept far apart from persecuting bad ones. The individual’s own impulses are similarly split and he directs all his love towards the good object and all his hatred against the bad one. As a consequence of the projection, the leading anxiety is paranoid, and the preoccupation is with survival of the self. Thinking is concrete because of the confusion between self and object which is one of the consequences of projective identification (Segal, 1957).
