The following thesis proposes to shed some light on the reality of Analytical Function, its physiology and the behavioural pathologies that derive from its dysfunction. We revisit the works of Freud, Jung and Lacan. Through a comparativistic approach of their “respective writings”, we discover the very fundamentals of Analytical Function. And all three had gathered their knowledge using a transdisciplinary approach (mythology, alchemy, Taoism, linguistics, mathematics etc…) Freud points out the main role of the drive by describing its four characteristics. In his “Magic Note Pad” he states the modalities of the psychic imprint. Analytical physiology comprises two distinct stages: the first one - “the common trunk”- refers to the imprint or engraving of the mnemonic marking. This stage unfolds according to a binary mode: the “It” for Freud, the “persona” for Jung and the “Imaginary” for Lacan. The second stage stems out of the common trunk on a ternary mode: the arborescent structure. This is the stage of the “I” for Freud, the “Self” for Jung and “the Real” for Lacan. This stage-just like the inter-chromosomal brew of the biological meiosis- produces an infinity of combinations. Binary and ternary modes represent the main phases of Analytical Function. Nevertheless the binary mode must not block out the ternary mode by locking the psyche into Lacan’s “Imaginary”. The psyche must go beyond itself and become its own artist. We show that the disequilibrium of Jung’s anima/animus archetype provokes these pathologies. We also notice that the “Judeo-Christian” way of thinking plays a censorship role and becomes an obstacle for the implementation of the ternary mode.
