This is a qualitative study on school violence. This research aimed at knowing, interpreting and comprehending the aggressive actions also known as bullying that happen among peers. This work took place at a public high school in the state of Rio de Janeiro. We intended to investigate the teachers and students perceptions concerning bullying as a type of school violence. Our hypothesis was that higher rates of bullying actions are related to the students difficulties at recognizing and dealing with cultural and identity difference that is built and rebuilt in the school environment. In order to comprehend the motives that were behind those aggressive actions, we investigated bullying as intolerance towards difference. We perceived that intolerance to difference is not enough to explain the severity of these aggressive acts. Thus, we investigated bulling as a maliciously trivial behavior. The source of this kind of behavior is a result of the inability to think and to reflect upon the meaning and the consequences of those aggressive acts. This inability is also a result of a modern society project that does not give the right value to an educational approach aimed at thinking and reflecting. We considered that intolerance and the banality of evil as expressions that motivate and explain bullying. We use the Theory of recognition by Charles Taylor and Axel Honnet and the concept of banality of evil by Hanna Arendt as a basis to our main hypothesis. As our methodological choices, we have had an extensive literature review, along with field observation, questionnaires and semistructured interviews with eight teachers and ten students who volunteered. As a conclusion to this work, we found that students know what bullying is, they know the practice and they are affected by this kind of violence, however they do not completely trust on their school asan institution that could be able to help them face the problem. Teachers know how to identify the bullying cases, but they do not mind comprehending the reasons that lead to those actions. At most, they think of some strategies in order to face the problem. The school management denies that bullying occurs and interprets these conflicts and aggressions as routineplays that normally take place at school. This research also pointed out that bullying is a sidelined and a trivialized theme at school.
