This paper deals with some ethic premises of the Psychiatric Reform, more specifically, with desinstitutionalization as deconstruction, establishing a dialogue with the ideas of Emmanuel Lévinas. The concept of alterity is considered at the interface of radical ethic included in this approach. The discussion points out that the incorporation of ethical premises from the Psychiatric Reform can help understand the different possibilities and social consequences of this process, considering the diversity of practices being constructed and the growing of substitutive services in the Mental Health field.
