This paper focuses on the educational relations in the context of public schools in the poor suburbs of urban centers aiming to identify a certain indiscipline and even a certain kind of violence inherent to the civilizing clash itself that is assumed by the act of education in general, from another kind of social violence more incisive which is a resistant to formal education. The author uses two personal experiences from two different schools: one in the poor outlining areas of Great São Paulo, where violence in the school reaches unbearable levels, and antoher in a traditional middle class school, where a certain kind of violence also occurs. The author also adds some reflections derived from a psychoanalytical focus on institutions to this comparative scheme attempting to show the conjunction of subconscious forces in the construction of a minimal pact for the establishment of educational relations.
