In this paper I interpret Montaigne's essay, "On Educating Children", as a pedagogical text through its performance of a distinct epistolary function, one that addresses the letter-recipient for the purpose of shaping the ideas, actions, and beliefs of that individual. At the same time, I also read "On Educating Children" within the context of the wider project of Montaigne's "Essays", which, as I suggest, is an ethical-aesthetic project of self-fashioning and self-cultivation. The net result is an interpretation of teaching as an ethical-aesthetic practice of the self, one that is in concert with the interpretation of Montaigne's writing of the Essays as a similar practice of the self. In order to build this case, I employ Michel Foucault's fourfold schema of ethical subjectivity, mapping that schema onto "On Educating Children", so as to reveal a unique pedagogy of self-formation--a pedagogy that works as much upon the self of the teacher as it does the self of the student.
