Within the depth-psychology corpus, ‘anal’ designates far more than a biological referent: it names a nodal zone of libidinal organisation around which character, object-relations, and psychopathology are comprehensively theorised. Freud’s foundational claim — that avarice, pedantry, and obstinacy each draw powerful contributions from anal-erotic sources — set the terms that Abraham, Ferenczi, Jones, and others would elaborate for decades. Abraham’s systematic study of the anal character traces how the retention-expulsion dialectic of early bowel life generates enduring personality structures: the withholding of gifts, the postponement of action, the reversal of orientation, and the coupling of sadistic with passive-anal impulses that underlies obsessional ambivalence. Ferenczi deepens this picture by reading anal character traits as vectors of displaced hatred and self-contempt, noting how flatus and soiling serve as instruments of ‘innocent’ revenge when tenderness fails. The corpus registers important tensions: whether anal erotism is a primary libidinal reservoir or a regressive fallback from oral and genital zones; how sublimation converts coprophilic interest into money, order, and creativity; and whether the anal-sadistic constellation is the exclusive province of obsessional neurosis or equally operative in melancholia and manic-depressive states. Hillman, engaging Kundalini frameworks, interrogates whether Freud’s anal-erotic reductivism adequately captures the symbolic complexity of the muladhara region. Liz Greene extends the developmental perspective into astrological psychology, reading toilet-training as a prototype of all conflicts over will, creativity, and authority.
