Aggressivity occupies a contested and generative position across the depth-psychology corpus, refusing reduction to simple pathology or instinctual discharge. Freud's late recognition—quoted pointedly by Bowlby—that 'non-erotic aggressivity and destructiveness' had been underestimated inaugurated a fault line that subsequent thinkers variously widened, redirected, or healed. For Panksepp, aggressivity is neurobiologically plural: predatory, affective-ragelike, and intermale forms emerge from distinct subcortical circuits, the RAGE system being the emotional core most directly continuous with human anger. Lacan situates aggressivity structurally within the mirror stage, as the constitutive underside of specular identification—an insight he treats not as pathological residue but as formative tension in subject-formation. Bowlby negotiates between Freud's primary aggressivity and his own attachment-theoretical revision, ultimately relocating chronic aggressivity in insecure attachment while preserving 'healthy aggression' within secure rupture-repair cycles. Levine reframes uninhibited aggression as biologically purposive assertiveness, with anger arising specifically when aggression is thwarted. Yalom's clinical usage is more bounded, invoking 'unconscious aggressivity' as a component of neurotic guilt requiring working through. Hillman, meanwhile, positions aggressivity among the shadow's vitality-potentials—sexuality, strength, emotionality—rather than as mere destructive force. The tensions among these positions—primary versus secondary, structural versus developmental, pathological versus adaptive—define the term's continued conceptual productivity.
the specular relationship, the original relationship of the subject to the specular image is set up in what is called a reaction of aggressivity
Lacan grounds aggressivity structurally in the mirror-stage relation, treating it not as aberration but as the originary tension constitutive of specular identification and subject-formation.

he seemed to abandon the notion of primary aggressivity altogether... he saw unresolved aggression as springing from insecure attachment, as opposed to the 'healthy aggression' of the secure
Bowlby's trajectory moves from Freudian primary aggressivity toward an attachment-theoretical account in which pathological aggression is a symptom of insecure attachment rather than an irreducible instinct.

when our aggression is not thwarted, but is clearly directed, we don't feel anger but instead experience the offensive attitude of protection, combativeness and assertiveness. Anger is thwarted aggression
Levine reframes aggressivity as biologically purposive and assertive when uninhibited, locating anger specifically as the experiential residue of blocked aggressive mobilization.

neurotic guilt must be approached through a working through of the sense of badness, the unconscious aggressivity, and the wish for punishment
Yalom positions unconscious aggressivity as a clinical component of neurotic guilt that demands therapeutic working-through, distinguishing it from the reparative work required by 'real' guilt.

few bridges have been built between this database and the nature of anger and rage in human experience... to understand anger, we must come to terms with that powerful brain force we experience as an internal pressure to reach out and strike someone
Panksepp argues that a neurobiological account of the RAGE system is prerequisite to understanding human anger, emphasizing the unbuilt bridge between affective neuroscience and phenomenological experience.

genetic selection experiments in both male and female rodents indicate that one can markedly potentiate aggressiveness through selective breeding within a half dozen generations
Panksepp demonstrates the heritable biological substrate of aggressivity through selective breeding evidence, underscoring its deep evolutionary and neurogenetic anchoring.

three distinct kinds of aggression can be aroused by applying ESB to slightly different brain zones: predatory aggression, angry, ragelike aggression, and perhaps intermale aggression
Panksepp establishes that aggressivity is neuroanatomically plural, with distinct subcortical circuits mediating qualitatively different forms of aggressive arousal.

children who have not been allowed to participate in a favorite activity will subsequently tend to exhibit higher levels of aggression, and such frustrations bring other dark thoughts to the surface such as prejudice toward minority groups
Panksepp links frustration and aggression through psychobiological evidence, showing that thwarted desire activates the RAGE system and produces broader hostile ideation.

these black shadows as earthy in the Ge or Demeter senses and thus as potentials of vitality (sexuality, fertility, aggressivity, strength, emotionality)
Hillman recasts shadow-aggressivity as a vitality-potential rather than mere destructive force, aligning it with fertility, sexuality, and strength within an archetypal-ecological register.

Anger has been associated with readiness to engage in aggressive behaviors... 93% of community residents and students reported feeling like acting aggressively in anger incidents
Empirical data confirm aggressivity as the dominant behavioral readiness component of anger, with verbal aggression far outpacing physical aggression in self-reported anger episodes.

male sexual behavior is closely linked with aggression. The sticklebacks are very short-sighted, so if a male fish sees another small fish approach, he gets into an aggressive fighting mood
Von Franz uses the stickleback's behavioral conflation of aggression and sexuality as an ethological illustration of instinctual pattern-collision relevant to human psychology.

serious aggressive postures are rarely seen in play-fighting... Sometimes play does end up in real fighting, but then the signs of behavioral rambunctiousness immediately cease. A behavioral tension emerges as RAGE and FEAR systems are presumably activated
Panksepp distinguishes play from genuine aggression through differential behavioral sequencing, showing that activation of RAGE and FEAR circuits marks the transition from play to real aggressive conflict.
