Lastly, Galtung notes that repression need not be violence associated with repressive regimes or declared on particular documents to be human-rights infractions, as "there are other types of damage done to the human mind not included in that particular tradition." From this sense, he categorizes alienation (i.e., "deprival of higher needs") as the fourth type of violence, leading to the third kind of structural violence, "structurally conditioned alienation"—or, "repressive tolerance," in that it is repressive but also compatible with repression, a lower level of structural violence.
