The oral stage occupies a foundational position in the depth-psychological corpus, yet its treatment is anything but uniform. Karl Abraham stands as the essential systematizer of this concept: working within and extending Freud's libido theory, he mapped the oral stage's two sub-phases — the sucking phase and the oral-sadistic biting phase — and traced their lasting imprints on character formation, object relations, and the psychopathology of melancholia and mania. For Abraham, fixation or regression to the oral stage yielded recognizable character constellations: an insatiable demandingness, clinging dependency, and an ambivalence toward objects that mirrored the cannibalistic wish to incorporate and destroy. Melanie Klein radicalized this inheritance, relocating much of the drama of the oral stage to the earliest weeks of life. Her work made oral-sadistic impulses — directed against the mother's breast — the seedbed of primary anxiety, splitting, and the paranoid-schizoid position, thus giving the oral stage a structural weight it had not possessed even in Abraham. What distinguishes the corpus as a whole is this sustained tension between the metapsychological (libido regression, fixation points) and the object-relational (the breast as primal good or persecutory object). The oral stage, in this literature, is not merely an early phase of development; it is the template upon which all subsequent relations to nourishment, dependency, envy, and trust are patterned.
in these patients the libido has regressed to the 'most primitive stage of its development known to us, to that stage which we have learned to know as the oral or cannibalistic stage.
Abraham argues that melancholic psychosis constitutes a libidinal regression to the oral-cannibalistic stage, establishing the clinical and theoretical centrality of this phase in the genesis of depressive disorders.

burdened throughout their whole life with the after-effects of an ungratified sucking period... The manner in which they put forward their wishes has something in the nature of persistent sucking about it.
Abraham demonstrates that ungratified oral experience produces a persistent character type marked by demanding, clinging, and insatiable social behavior traceable to the sucking sub-phase.

The most typical form of sublimation seems to be the character trait of optimism... it contrasts with the seriousness and pessimism of certain anal types, particularly those associated with early disappointments of oral gratification.
Abraham's expositor establishes that optimism is the characteristic sublimation of oral erotism, while early oral disappointment — especially during the biting sub-phase — generates ambivalence and pessimism in later character.

the close connection of the component of cruelty in infantile instinctual life with oral erotism will become evident in the character-formation of the individual as elsewhere.
Abraham links oral erotism to the sadistic component-instinct, establishing cruelty as an intrinsic aspect of oral character formation rather than an independent drive.

biting represents the original form taken by the sadistic impulses. Undoubtedly the teeth are the first instruments with which the child can do damage to the outer world.
Abraham identifies the biting act as the phylogenetically and ontogenetically primary expression of sadism, anchoring oral-sadism within the developmental sequence of the instincts.

Whether in this early period of life the child has had to go without pleasure or has been indulged with an excess of it, the effect is the same. It takes leave of the sucking stage under difficulties.
Abraham formulates the paradox that both oral deprivation and over-indulgence produce fixation, establishing the clinical equivalence of the two aetiological extremes for oral pathology.

certain contributions to character-formation originating in the earliest oral stage coincide in important respects with others derived from the final genital stage. This is probably explicable from the fact that at these two stages the libido is least open to disturbance from an ambivalence of feeling.
Abraham observes a structural kinship between the earliest oral and the final genital stages as zones of minimal ambivalence, offering a theoretical rationale for their shared character contributions.

I also became aware of the fundamental part which oral-sadistic impulses play in destructive phantasies and corresponding anxieties, thus finding in the analysis of young children full confirmation of Abraham's discoveries.
Klein credits Abraham's discoveries regarding oral-sadism while announcing her own clinical extension of them, positioning her child analyses as empirical confirmation and theoretical deepening of the oral stage's role in anxiety and phantasy.

According to Freud a similar double function attaches to the anal aperture of the alimentary canal as well... As with the lip-zone, the erotogenic capacity of the anal zone must be presumed to vary with each individual.
Abraham situates oral erotism within Freud's broader schema of erotogenic zones, contrasting the lip-zone's double function with the anal aperture to develop a comparative theory of zonal libido.

obsessional trends come to the fore; they both express and bind oral, urethral and anal anxieties... The lessening or overcoming of these symptoms amounts to a modification of oral, urethral and anal anxieties.
Klein argues that obsessional symptomatology in early childhood functions to bind oral anxieties, integrating the oral stage into a broader account of normal and neurotic development during the second year.
