Walter Burkert’s Homo Necans (1972; English translation 1983) stands as the defining text through which the depth-psychology and comparative-religion corpus engages the proposition that killing — sacrificial, ritual, and martial — constitutes a founding condition of human civilization rather than an aberration from it. The work’s central argument, articulated with formidable classical and anthropological learning, is that solidarity is achieved through sacred crime: that human communal life is structured by institutionalized violence channeled and sublimated through sacrificial ritual. Burkert draws the term’s conceptual engine from Konrad Lorenz’s ethology of aggression, a genealogy he acknowledges candidly in his preface, and presses it into an account of Greek religion in which sacrifice, hunting, and funerary ritual share a common grammar of killing-and-restitution. The book’s most axiomatic formulation — ‘Only homo necans can become homo sapiens’ — crystallizes its anthropological wager: that lethal violence is not incidental but constitutive of the symbolic and cognitive achievements we name humanity. Burkert’s interlocutors in the wider corpus include Frazer, Harrison, and Lévi-Strauss, and his thesis enters into implicit dialogue with depth-psychological accounts of aggression, guilt, and atonement. The term thus anchors discussions of sacrifice, myth, ritual substitution, and the archaic roots of tragic consciousness across classical studies, history of religion, and depth psychology.
