observed the Yanomami people from 1970 to 1971, and wrote The Last Frontier. He briefly visited the Guaraní which migrated from Paraguay to Brazil in his last expedition in 1974. In 1971 he became lecturer at the fifth section of the EPHE, and was promoted to director of studies of the religion and societies of South American Indigenous peoples in October 1975. That same year he left his office as researcher of the Laboratory of Social Anthropology—which he occupied since 1961—after conflicts over Lévi-Strauss's theories. In 1977 he took in part in the establishment of the journal Libre alongside the former members of Socialisme ou Barbarie Miguel Abensour, Cornelius Castoriadis, Marcel Gauchet, Claude Lefort, and Maurice Luciani. Later that year, Clastres, aged 43, died in Gabriac, Lozère, on 29 July, in a car accident. Works Chronicle of the Guayaki Indians Clastres's first book was originally published in France by Plon in 1972 under the title Chronique des indiens Guayaki: ce que que savent les Aché, chasseurs nomades du Paraguay (Chronicle of the Guayaki Indians: The Knowledge of the Aché Hunter Nomads of Paraguay). He was interested in Guayaki because there was little research on them since Alfredo Stroessner's dictatorship forced them to live under territorial restriction and launched a pacifying campaign between 1959 and 1962. In the book, the author describes Guayaki culture with a focus on their cycle of life and their "daily struggles for survival." He describes their mores on rites of passage, marriage, hunting, warfare, and death, as well as their relation with non-Indian people and nature. In 1976 Paul Auster, then a "penniless unknown", translated the book into English but it was only published in 1998 by Zone Books. Auster translated the work because he was fascinated by Clastres's prose, which "seemed to combine a poet's temperament with a philosopher's depth of mind." Although its literary qualities have been what attracted Auster, the work has been criticized as "romantic". Anthropologist Clifford Geertz said Clastres had a "Rousseauian primitivism, the view that 'savages' are radically different from us, more authentic than us, morally superior to us, and need only to be protected, presumably by us, from our greed and cruelty." Bartholomew Dean, writing for the journal Anthropology Today, declared, "Clastres' ahistoricism, rhetorical romanticism, and museumification sadly obscures the ongoing challenges facing indigenous peoples like the Guayaki." In opposition to Geertz and Dean, David Rains Wallace said it
