This paper deals with the term 'metapsychology' and its different usages, especially emphasizing the concept of 'point of view' in order to stress its epistemological importance. Two metapsychological areas are then suggested, each with different contents. After an enumeration and brief analysis of the main hypotheses of the Kleinian school, and applying the aforementioned distinction, the following points of view, contained in the Kleinian developments, are put forward and explained; namely, the positional, the economic policy, the dramatic and the spatial points of view.
