Aristotle's ontogenesis: a theory of individuation which integrates the classical and developmental perspectives.

The effects of the classical/developmental split in analytical psychology are described. No underlying issues explaining the nature of the split have been clearly enunciated. The schools can, however, be distinguished by their differing epistemologies. These are the hermeneutic and transcendental branches of phenomenology. The use of these epistemologies leads their proponents to either an immanent or transcendent concept of the divine, respectively. The theoretical break between Freud and Jung can, in part, be attributed to their espousal of determinism and teleology, respectively. This conflict has been continued in analytical psychology with the developmentalists most often advocating determinism, and the classicists usually championing teleology. The dissimilar causal theories lead to different concepts of the nature of individuation. Aristotle's fourfold theory of causality, of which determinism and teleology are two categories, can be seen to be an ontogenic theory rather than a classification of causal influences. Applying his theory to the process of individuation provides an ontogenesis that more accurately describes the process itself, and unifies the developmental and classical theories. Intimations of this formulation in Jung's work are described. More explicit conceptions of this idea in the work of two contemporary analytical psychologists and that of Wilfred Bion are also presented.
