The primary self and related concepts in Jung, Klein, and Isaacs.

In this paper, I have tried to re-examine my understanding of early psychic processes and contents. This has involved comparing and contrasting the ideas of Jung, Klein, Isaacs, and Fordham, with an emphasis on the contributions of Fordham. Fordham's postulate of a primary self that deintegrates and reintegrates is a model of the mind that combines structure and dynamics, and which, moreover, helps to describe what is observed in infant observations and infant research. Infant observation has been used to illustrate these concepts, and clinical material used to show how the same concepts can be used to describe impairments to psychic development. To pursue this study I have had to construct for myself models that describe and explain. I am aware that they are just as inaccurate as they might be accurate, because they imply that there is an answer to the questions I am asking, and that there is a way of describing and explaining what 'the answer' is. 'Nature is always too strong for principle', wrote Hume (Hume 1751, p. 121), and this is particularly true of the ultimately unknowable self.
