No fewer than three recent mass shooters have said they found inspiration in the French intellectual Renaud Camus’ theory of “the Great Replacement,” a xenophobic and racist claim that “European” or “white” culture is being “replaced” through immigration. Camus outlined this theory in a 2011 book entitled Le Grand Remplacement that he later rewrote and translated into English as You Will Not Replace Us! (2018), a title clearly intended to echo the chant of the white supremacists at the 2017 Charlottesville rally. Pharos has reported on how this theory appears, often in connection with references to Greco-Roman antiquity, on various hate sites, and ancient historian Sarah Bond has traced the history of this theory, uncovering a long tradition of such thinking well before Camus published his work. But Greco-Roman antiquity is not just a touchstone for those who subscribe to Camus’ theory: his treatise itself takes its starting point from a reading of an ancient Greek philosophical text and is peppered throughout with references to antiquity in support of his claims.
