The work in a school offers the opportunity to think about the complexity of issues that involves the construction of knowledges associated with the construction of bonds of intersubjective relationships. This research focused in the unique and incessant production of subjective experience that expresses itself in life and, in this particular case, among the collective practices that are part of the polyphonic scenario of a school. This work developed the theme of the subjective experience as a singular and permanently unfinished production, with the contributions of the thoughts of Wittgenstein and Bakhtin, two philosophers of language. Inside this perspective, language, as a cultural practice that characterizes our humanity, redefines the interiority of this experience recognizing it as unique and, at the same time, determined by the characteristics of a certain historical and cultural time. In this study, we deal with the concepts of ethics and aesthetics, both strong references inside the philosophies of language of Wittgenstein and Bakhtin. These concepts allowed the expression of a way of looking at the experience at school and faced a kind of tension in the approach of the singularity of subjective production and it's construction as action and reflection.
