Under the guest editorship of Michael Potegal (Univ. of Minnesota), Peace Review: A Journal of Social Justice invites essays for a special issue (31.1), Aggression in Humans and Other Animals: What Do We Know Now? Where Do We Go from Here? Our current understanding of aggression is a complex tapestry whose motifs range from genetically determined patterns of attack in other animals and facial expressions of anger in us to developmental influences, such as parenting styles and developmental trajectories of aggression, to environmental factors that include noxious, aggression-provoking stimuli like heat and pain. Woven together, research threads from ethological and physiological studies in animals and from individual and social psychological studies of human behavior yield related typologies of aggression: animal predation and human hunting; animal offense and defense, human proactive and reactive aggression. Other shared aggression-related motifs include personality factors, along a dimension from friendly to hostile; the phenomena of dominance (e.g., bullying among humans) and sexual rivalry (e.g., human jealousy), the implicit and explicit calculation of costs and payoffs of aggression, and the hormonal and brain mechanisms subserving these impulses.

Motifs unique to humans include the technology of aggression, from gun violence to nuclear weapons; symbolic representation, belief systems, and language, from insults that trigger bar fights to mass propaganda preceding and accompanying genocide; and political leadership of large scale social organization, as in the formation of armies and the conduct of war.

This is a call for thoughtful essays that engage the state of the art in aggression research to seek new connections and new views, challenging and expanding the ideas in this tapestry of knowledge about ourselves, other animals, or both. Clearly written submissions are sought, free of jargon, with simple titles, without embedded footnotes and endnotes, although we accept in-text citations, and will run recommended readings. Academics, activists, artists, and practitioners are encouraged to submit essays that appeal to a wide readership.

Under the subject line Aggression in Humans and Other Animals, essays (2,500–3,500 words in length), along with 1–2-line author biographies, should be sent to Robert Elias (editor in chief) or Shawn Doubiago (managing editor) at Peace Review ( by 15 October 2018. Please direct content-based questions or concerns to the guest editor, Michael Potegal ( For more information on submitting essays, visit
