Infantile sexuality stands as one of the most contested and generative concepts in the depth-psychology corpus, introduced with systematic force in Freud's 1905 Three Essays on the Theory of Sexuality and subsequently debated, revised, and contested by virtually every major figure in the tradition. Freud's foundational claim — that sexual life does not begin at puberty but is active, polymorphously organized, and erotogenically distributed from earliest infancy — overturned the Victorian presumption of childhood innocence and established the libidinal origins of neurosis. The Three Essays trace infantile sexuality through auto-erotism, component instincts, erotogenic zones, and the diphasic structure of object-choice, culminating in the latency period. Jung accepted the observational data while fundamentally contesting the sexual terminology, arguing that what Freud called infantile sexuality properly belongs to a 'presexual stage' energized by undifferentiated libido rather than sexuality proper — making the latency period theoretically otiose. Ferenczi introduced a further complication, insisting that much of what appears passionately sexual in infancy may be secondarily imposed by adult eroticism. Berry, reading from an archetypal perspective, subjects Freud's fantasy of infantile sexuality to critical deconstruction, isolating its organizing assumptions about developmental hierarchy, bodily shame, and the privileging of genital unity. The term thus anchors a fundamental debate about the nature, scope, and chronological reach of sexuality itself.
At its origin it attaches itself to one of the vital somatic functions; it has as yet no sexual object, and is thus auto-erotic; and its sexual aim is dominated by an erotogenic zone.
Freud defines the three essential characteristics of infantile sexual manifestation — somatic attachment, auto-erotism, and erotogenic zone dominance — establishing the structural foundation of the concept.

the forces destined to retain the sexual instinct upon certain lines are built up in childhood chiefly at the cost of perverse sexual impulses and with the assistance of education.
Freud argues that the psychic barriers against sexuality — shame, disgust, morality — are constructed in childhood precisely through the suppression and transformation of infantile perverse impulses.

this same disposition to perversions of every kind is a general and fundamental human characteristic.
Freud grounds infantile sexuality in a universal 'polymorphously perverse disposition,' contending that the child's erotic openness is not pathological but constitutive of human sexuality as such.

much of what appears as passionate in infantile sexuality may be a secondary consequence of the passionate behavior of adults, forcibly imposed on children against their will and, so to speak, artificially implanted in them.
Ferenczi fundamentally revises the Freudian model by arguing that adult eroticism, not innate disposition, generates the passionate dimension of infantile sexuality, thereby implicating trauma in its very constitution.

The theory of the latency period is an excellent example of the incorrectness of the conception of infantile sexuality. But there has been no error of observation. On the contrary, the hypothesis of the latency period proves how exactly Freud observed the apparent recommencement of sexuality. The error lies in the conception.
Jung concedes Freud's observational accuracy while insisting that the theoretical concept of infantile sexuality is misconceived, with the latency period serving as the clearest evidence of the category error.

Childhood sexuality is inferior, lower, and not of our better selves. It is shameful from the perspective of more mature faculties.
Berry subjects Freud's fantasy of infantile sexuality to archetypal deconstruction, exposing the hierarchical and shame-laden developmental assumptions embedded in its conceptual structure.

the infantile, polyvalent germinal state is not just a singularly perverse preliminary stage of normal and mature sexuality; it seems perverse because it is a preliminary stage not only of adult sexuality but also of the whole mental make-up of the individual.
Jung reframes the infantile germinal state as a pleroma of psychic potentials, not reducible to sexuality, arguing that Freud's sexual reading imposes an artificially narrow lens on the child's total developmental matrix.
, The Interpretation of Nature and the Psyche, 1955thesis
the discovery of precocious sexual fantasies, which seemed to be the source of the neurosis, forced Freud to assume the existence of a richly developed infantile sexuality.
Jung traces the historical-clinical necessity that drove Freud toward the concept, acknowledging the empirical pressure of early sexual fantasy material while framing the theory as a forced inference.

The first of these begins between the ages of two and five, and is brought to a halt or to a retreat by the latency period; it is characterized by the infantile nature of the sexual aims.
Freud articulates the diphasic structure of object-choice, establishing infantile sexuality as the first wave of an interrupted developmental arc whose residues determine adult erotic life.

the infant takes to sucking for pleasure this object is given up and is replaced by a part of its own body; it sucks its thumb or its own tongue. For purposes of obtaining pleasure it thus makes itself independent of the concurrence of the outer world.
Freud elaborates the auto-erotic mechanism of infantile sexuality through thumb-sucking, demonstrating how the infant's pleasure detaches from the nutritional object and becomes self-sustaining.

In infants we find that libido as energy, as a vital activity, first manifests itself in the nutritional zone, where, in the act of sucking, food is taken in with a rhythmic movement and with every sign of satisfaction.
Jung reinterprets infantile oral activity through a non-sexual libido concept, locating the infant's pleasure-sucking in undifferentiated vital energy rather than properly sexual excitation.

If the libido, in Freud's sense, comes into existence only at puberty, it cannot be held accountable for earlier infantile perversions — unless we regard them as 'psychic faculties,' in accordance with the theory of components.
Jung exposes a theoretical inconsistency in Freud's libido concept as applied to infantile sexuality, pressing the question of what energetic principle actually animates pre-pubertal erotic activity.

the instinct for knowledge in children is attracted unexpectedly early and intensively to sexual problems and is in fact possibly first aroused by them.
Freud links infantile sexuality to the epistemophilic instinct, arguing that the child's passion for knowledge is originally mobilized by sexual questions, giving infantile sexuality an intellectual as well as somatic dimension.

all comparatively intense affective processes, including even terrifying ones, trench upon sexuality — a fact which may incidentally help to explain the pathogenic effect of emotions of that kind.
Freud extends infantile sexuality to encompass affective arousal generally, arguing that strong emotions in childhood — including fear — converge with sexual excitation and thereby acquire pathogenic potential.

Nature's purpose of establishing the future primacy over sexual activity exercised by this erotogenic zone by means of early infantile masturbation, which scarcely a single individual escapes.
Freud asserts the near-universal occurrence of infantile masturbation as evidence for the erotogenic primacy of the genital zone, grounding the claim in teleological biology.

Those authorities who regard the interstitial portion of the sex-gland as the organ that determines sex have on their side been led by anatomical researches to speak of infantile sexuality and a period of sexual latency.
Freud cites anatomical research in support of the concept, noting that endocrinologically-oriented scientists had independently arrived at both infantile sexuality and the latency period through somatic investigation.

In none of the accounts which I have read of the psychology of this period of life is a chapter to be found on the erotic life of children.
Freud marks the pre-theoretical silence in developmental psychology regarding childhood eroticism, establishing the conceptual novelty and necessity of the infantile sexuality thesis.

Freud's development from Darwin remained confined by the nineteenth century. Our simian self became only the biological id of infantile sexuality.
Hillman situates Freud's concept of infantile sexuality within a broader critique of nineteenth-century biologism, arguing that it reduces the archaic human inheritance to a merely instinctual and developmentally inferior register.

The 'amnesia of childhood' is an inference from the psychology of neurosis, just as is the 'polymorphous-perverse' disposition of the child.
Jung challenges the evidential basis of both childhood amnesia and polymorphous perversity, arguing that both are theoretical artifacts derived from neurotic material rather than direct observations of normal childhood.
