In the process of characterizing the dialects of adversarialism and mutualism, a case is made for a reciprocal approach to peacemaking criminology. As part of the rationale for a reciprocity of making war or making peace, critics are leveled at both 'peacemaking' and 'warmaking' criminology. The purposes of this essay are, on the one hand, to reinvigorate peacemaking criminology that is often too isolated and marginalized from hegemonic interaction to influence struggles for positive peace and social justice. On the other hand, the article seeks to expose the kinds of reflective thinking and social analysis that a peacemaking criminology must confront if its goals of overcoming or neutralizing a warmaking criminology are ever to materialize at home and abroad.
