The term 'biting' traverses the depth-psychology corpus along three distinct axes that only partially intersect. In the I Ching commentarial tradition — spanning Wilhelm, Wang Bi, Huang, and the Taoist interpreters — biting is the central operative metaphor of Hexagram 21 (Shi He, 'Biting Through'), where it signifies the forceful, clarifying act of removing obstruction: juridical, moral, and alchemical. Here biting is not aggression but resolution, the mouth closing upon what impedes union. A second axis runs through Kleinian object-relations theory, where Melanie Klein's observation of infants biting the nipple with apparent pleasure introduces the problem of oral sadism and its relation to love, envy, and the constitution of the 'good' and 'bad' breast. This is biting as the earliest ambivalent meeting of drive and object. The third axis is neurobiological: Panksepp distinguishes 'quiet-biting attack' — predatory, instrumentally calm — from affective rage-attack, a dissociation with significant implications for understanding aggression as a multi-systemic phenomenon. Across all three registers, biting marks a threshold: between obstruction and resolution, between pleasure and destruction, between predation and rage. The term thus condenses questions of agency, orality, punishment, and the ambivalent sources of desire that animate depth psychology's core preoccupations.
Biting through has the meaning of the mouth closing when eating something... Acting with unfailing clarity, acting only after clear understanding, it has the meaning of action that is not in vain; therefore it is called biting through.
This passage establishes the Taoist interpretive thesis that biting-through names a mode of action grounded in lucid discernment — the physical act of the mouth closing becoming an emblem of decisive, non-errant conduct.

the active babies who bit the nipple most often seemed somewhat to enjoy biting; their biting was leisurely and quite unlike the uneasy chewing and gnawing of unsatisfied babies.
Klein uses observed infant behaviour to argue that pleasurable biting of the nipple represents an early oral-libidinal expression distinct from frustrated gnawing, positioning the act at the origin of the ambivalent relation to the object.

Shi means to bite. He means to close and unite. Literally, Shi He is to close the mouth to bite. This gua indicates a situation where, after biting, the obstruction is eradicated.
Huang's philological analysis of the hexagram name grounds the symbolic significance of biting in the structural logic of the trigram: the act of closing the mouth upon an obstacle produces union by elimination.

Shi is biting; fu usually means skin... the biting has to be forceful. The Yao Text shows a vivid picture, in the form of a story, of this firm resolution to abandon bad conduct, likening it to taking a forceful bite of tender meat, even burying his nose in it.
Huang's commentary on the second line establishes that the force of biting is proportional to the gravity of the obstruction, linking physical intensity to moral and juridical rectitude.

"Dried meat" signifies toughness; "yellow," centrality or the Mean; and "metal," hardness... biting through dried meat... one treads on a place that is not right for him and yet remains capable of administering the appropriate punishment.
Wang Bi's commentary reads biting-through dried meat as a figure for the exercise of punitive authority under conditions of positional difficulty, where the hardness of the object tests and confirms the capacity for just governance.

In order that it be possible to bite together so things go smoothly, there must be a ruler in charge... Thunder and Lightning: this constitutes the image of Shihe [Bite Together].
Wang Bi articulates the structural necessity of a central authority for biting-through to succeed, associating the hexagram's image of thunder and lightning with the unified force required to consummate decisive action.

Biting on dried meat, running into poison. There is a little shame, but no blame... if one acts in error, it will surely bring on trouble, like biting into dried meat and coming upon poison.
Liu I-ming reads the third-line biting metaphor as a warning about premature or insufficiently grounded action — the encounter with 'poison' within what appeared nourishing signals the danger of advancing before principle is truly penetrated.

quiet-biting attack is typically evoked during ESB of the dorsolateral hypothalamus, while affective attack sites are more concentrated in the ventrolateral and medial hypothalamus.
Panksepp's neuroanatomical distinction between quiet-biting attack and affective rage-attack demonstrates that biting as predatory behaviour and biting as emotionally charged aggression are mediated by separable neural substrates.

It leaped viciously toward me with claws unsheathed, fangs bared, hissing and spitting... Within a fraction of a minute after terminating the stimulation, the cat was again relaxed and peaceful.
Panksepp's account of electrically stimulated affective attack — in which fangs and claws become instruments of rage before instantly yielding to calm — illustrates the neural discreteness and intensity of the RAGE system's mobilisation of oral-aggressive behaviour.

specific need states that sensitize distinct consummatory reflex tendencies (e. g., licking, biting, chewing, and
Panksepp briefly situates biting within a taxonomy of consummatory reflexes sensitised by need states, implying that the act belongs to a differentiated repertoire of motivated oral behaviours rather than constituting a unitary instinct.

You bring the apple to your mouth, open your jaws and take a powerful bite. As you start to chew, saliva flows copiously from your glands. The sweet and tangy taste is almost orgasmic.
Levine uses the phenomenology of biting an apple as a phenomenological entry-point into embodied presence, demonstrating how the somatic act of biting anchors awareness in the body's pleasurable, pre-reflective engagement with the world.
