[pt] A dissertação consiste numa pesquisa teórica que propõe o argumento de os ataques ao enquadre, frequentemente empreendidos pelos casos-limite, constituírem a tentativa clínica de passagem para o campo do uso do objeto. A agressividade não bem manejada pelo ambiente prejudica o reconhecimento da externalidade, resultando numa tendência à destruição que se torna característica central da clínica com estes casos. O trabalho do negativo malsucedido impossibilita a construção do espaço da ausência no psiquismo, fundamental à construção de representações, à instauração das fronteiras intrapsíquicas e intersubjetivas e ao investimento em objetos substitutos. Os prejuízos relativos à agressividade e ao trabalho do negativo redundam na precariedade das fronteiras entre o eu e o outro, sugerindo a prevalência de uma relação pautada na vertente subjetiva do objeto, logo não reconhecido em sua natureza externa. As contribuições de Winnicott e Green fundamentam nossa hipótese de que a destrutividade – expressa na clínica dos casos-limite através dos ataques ao enquadre – consiste numa tentativa atuada de passagem para o campo do uso do objeto, que consolida a unidade do self ao mesmo tempo que possibilita o reconhecimento do objeto na realidade compartilhada. / [en] The dissertation consists of theoretical research proposing the argument that the attacks on the setting, often undertaken by borderline patients, consists on a clinical way of reaching the use of an object. The aggressiveness not well handled by the environment affects the recognition of the externality, resulting in a tendency towards destruction which becomes the central feature in the borderline clinic. The unsuccessful work of the negative precludes the construction of an absence space in the psyche, fundamental to the construction of representations, the introduction of intrapsychic and intersubjective borders, as the investment in substitute objects. Losses related to aggressiveness and the work of the negative result in precarious boundaries between self and other, suggesting the prevalence of a relationship based in the subjective aspect of the object, not just recognized in his external nature. The contributions of Winnicott and Green underlie our hypothesis that the destructiveness – expressed in borderline clinic through the attacks on the setting – consists in an actuated way to reach the use of the object, which consolidates the unity of self while enables the recognition of the object in shared reality.

Cette thèse explore la clinique de l’enfant violent au travers du concept de « violence infantile » qui permet d’en dégager toutes les potentialités et de maintenir un regard créatif sur les « cliniques de l’extrême ». Loin de défendre un point de vue innéiste ou déficitaire, cette thèse envisage le recours à l’acte violent, chez des enfants présentant des troubles de la personnalité « narcissiques-identitaires », comme le témoin des faillites précoces de l’organisation du narcissisme. Au-delà de ses aspects manifestes, la « violence infantile » constitue donc un organisateur central des pathologies narcissiques dont nous retrouvons les traces jusque dans la vie adulte. Son articulation avec le geste explore la manière dont l’enfant a pu trouver à organiser sa vie pulsionnelle au contact de l’objet maternel. En lieu et place du jeu de la destructivité, l’enfant a fait l’expérience d’une destruction. La thèse envisage les destins du geste spontané confronté à un environnement qui ne s’est pas laissé utiliser. La « violence infantile » témoigne d’un jeu de bébé qui aurait dégénéré, elle est envisagée comme une tentative d’exploration de la psyché de l’objet. Cela implique des remaniements du cadre et de la posture du clinicien, qui l’engagent corporellement, condition nécessaire pour qu’une symbolisation des enjeux précoces contenus dans la « violence infantile » puisse avoir lieu. / In this thesis, the violent child’s clinical exploration is questionned using the concept of « infantile violence », which allows us to extract all the potentialities and to maintain a creative view on the extreme situations of subjectivity. In this work, children with serious personality disorder using violent acts are considered as witnesses of early failures of narcissistic organization. « Infantile violence » constitutes a central organizer of the narcissistic pathologies whose traces may be found in the adult state. His articulation with the gesture explores the way by which the child has organized his instinctual life in contact with the maternal object. In state of playing destructivity the child has experimented destruction.This work discusses the destiny of a spontaneous gesture which is confronted by an environment that does not allow for it to be used. « Infantile violence » shows a baby’s play that could have been degenerated, it is seen as an attempt to explore the object’s psyche. These facts involve revisions of setting and clinician’s posture. This leads him to a corporal engagement which is a necessary condition to allow an infantile violence symbolization.
