terminology

There's some degree of complexity about the use of the term,  "pre-oedipal field".    Different writers give it a different meaning.  For those who follow Klein,  along the lines of Bion and Meltzer, there are gradations between being in the paranoid-schizoid position and being able to accept the value of others.

Even -- or especially -- if you think you don't view the world through some or various gradations of this consciousness, you are bound to do so, for it is part of "human nature" and indeed, if the world were not given coherent by means of your unconscious projections, you would see yourself as being equal to every other individual, whilst not possessing any essential characteristics that define your overall identity.  This status of individuality applies to few -- and even then, not always to the few.

This ubiquitously expressed, regressive part of our consciousness is particularly adept at bringing us into conformity with power hierarchies by re-proportioning parts of our personality so as to be able to accept our position within them as "natural". We project the sense of self-competency upwards in the hierarchy, and the sense of our own incompetency downwards towards those who are defined as lower than us in the social/political hierarchy. The altogether human tendency to project into others is so ubiquitous that one would not do justice to the human mind to label this dimension as always and inevitably pathological.

In some cases, the "pre-oedipal field" can also have a positive value if it is not entirely immature but has developed towards appreciating the existence of others. Shamanistic initiation ought to bring about such a sense of the nature of being as a quality of sharing one's existence with others. To empathize also involves projecting, only we project our understanding and sensations into situations that are not purely ours.
