Educational theory and practice is dominated by mass formal schooling systems, which routinely and unjustly harm many students. I call this stance "educational pacifism," and in this paper argue that Montessorians ought to be educational pacifists. That is, they ought to recognize, understand, and reject systemic educational harm and ensure that it does not occur in their own practice, so that Montessori students are not harmed during their education and so that Montessori education might provide a nonharmful educational alternative to mass formal schooling. I suggest that Maria Montessori was, broadly speaking, herself an educational pacifist, and that not only is educational pacifism the morally right position for a Montessorian, but also that it is naturally a Montessorian position.
