All My Relatives: Lakota Ontology, Belief, and Ritual. Lincoln: University of Nebraska Press, 2018. Can a twenty-first-century comparative anthropology, in the style of Claude Lévi-Strauss and Mary Douglas, compel us so-called moderns to live in less ecologically destructive and more spiritually enriching ways that go beyond binaristic understandings of nature and culture? In All My Relatives: Lakota Ontology, Belief and Ritual, David C. Posthumus seeks to accomplish this by presenting a reinterpretation of nineteenth-century Sioux ontology through a “Descolian animist perspective” (15). His intention is to resituate Lakota ethnometaphysics within a long-standing practice of multispecies coexistence and to complicate dogmatic understandings of spirituality among the Sioux. Informed by participant-observation, interviews, and analyses of ethnohistorical literature, including writings by Ella Deloria and Alfred Irving Hallowell, along with more contemporary works by Vine Deloria, Jr., Tim Ingold, Eduardo Kohn, and Eduardo Viveiros de Castro among others, Post-humus delves into the complexities of Lakota spirituality, belief, and ritual. Lakota life and worldviews, both historically and contemporarily, encompass human and more-than-human worlds, and Posthumus attempts to show how these beliefs and practices have persisted and changed over time. In the introduction, Posthumus discusses how English terms such as “religion,” “spirituality,” and “society” do not necessarily capture Lakota (Western Sioux) understandings of their religious phenomena and experiences. As an English writing anthropologist, he nevertheless settles uncomfortably with his use of the terms in order to analyze and interpret, through a new animist framework, Lakota ontology, spiritual belief, and ceremonial practices. For the Lakota, spirituality, society, and the environment, as well as conceptions of humans and their nonhuman counterparts, are not considered as separately bounded categories, as is often imagined in Western, Cartesian understandings of self and the natural world. Thus, Posthumus’s analysis considers human persons, nonhuman persons, and the spirits and belief systems that underlie their entire cosmology and, borrowing from Ingold, the multiple and idiosyncratic Lakotan ways of being-(alive)-in-the-world (31). One of the objectives of his study, in addition to a reinterpretation, is to make readers appreciate Indigenous lifeways, including their relation to other-than-human life-forms, and to show how we might move toward the future in less destructive ways than those brought on by modernized and Christianized practices that position humans as supreme beings with dominion over all living species. According to the Sioux, despite the human-like [End Page 297] qualities and awareness of nonhuman persons and spirits, human beings themselves are the less powerful entities in the natural state of things (98). In other words, in Sioux cosmology, human beings are simply a strand in the web of life that includes nonhuman persons (i.e. animals and stones) and otherworldly entities and spirits. Posthumus situates himself, a white male, as an ethnographer and anthropologist of the Lakota (with the help of his friends and interlocutors), and in the introduction justifies his “old-school” approach through utilizing Phillipe Descola’s own “cleansing” and reformulation of early structural anthropology, sans the social evolutionary theory that characterized early understandings of animism (40). The nine chapters that follow articulate the various ways in which Lakota beliefs and practices are manifest through rituals and in kinship systems that are foundational to the very essence of their worldview, and in particular, enact and reproduce human/other-than-human entanglements in Lakota life. Contrary to widespread assumptions, the Lakota, like many other Native American peoples, do not necessarily believe that everything found in the world has a spirit. What they call wak’a, or “an incomprehensible, mysterious, nonhuman instrumental power or energy” (36) that circulates through both human and nonhuman persons and bodies (rocks, trees, waterfalls, humans, animals, medicine bags) through specific actions and at specific moments, is what potentially animates both human and nonhuman persons. Rather than a rock or some other form inherently having life in its being, it becomes animated through personal and/or collective relations with it. Everything...
