Eduardo Kohn’s How Forests Think: Toward an Anthropology Beyond the Human asks humans to understand the world through the perspectives of other than humans. Further, through his research, Kohn encourages anthropologists to engage in ethnography beyond the human. Kohn weaves his own ethnographic research conducted alongside Amazonian Avila with various theories such as that by Viveiros de Castro, John Berger, Judith Butler, Donna Haraway, and Tim Ingold to just name a few whose ideas make appearances in the book. Through the intricate weave between ethnographic research and theories, Kohn claims we need to see the world/us from beyond the human perspective because such paradigm shift will not only bring about drastic destabilization of what we take for granted, but also completely change the way we see and interpret the world. Through this book, Kohn gives an example of how humans can remain distinct yet maintain their connection to other than humans at the same time. Kohn, an associate professor of Anthropology at McGill University, divides the book into six chapters. Each chapter lays a building block for understanding the following chapters.
Justifiably, Kohn begins the first chapter by discussing language structure, the basis of human ontology. In Chapter One: The Open Whole, Kohn sets out to separate thought and language. The difference between symbols, icons, and indices is key to understanding the author’s claims. To borrow Kohn’s words, “unlike iconic and indexical modes of reference, which form the bases for all representation in the living world, symbolic reference is, on this planet at least, a form of representation that is unique to humans” (31). Icons are based on their virtue of resemblance to the objects/events that icons are attempting to represent, while indices represent through direct link to the objects/events (32). Any beings in non-human form have access to icons and indices. On the other hand, symbols built upon icons and indices are only privy to humans as context-dependent form of communication/language (39). Based on such framework, Kohn claims the symbolic is both continuous with the rest of nature and novel at the same time (56). In other words, through a breakdown of language into icons, indices, and symbols, Kohn convincingly claims humans are distinct and linked to nature at the same time. If one is interested in how humans are deeply related to nature, I suggest one read David Abram’s The Spell of the Sensuous alongside this book because it gives an especially accessible explanation of the relationship between human language, temporality, and landscape.
In Chapter Two titled The Living Thought, Kohn builds from the claim he made in the previous chapter that humans are simultaneously distinct from and very much related to nature, to suggest that all living beings think, not just humans. Through this chapter, Kohn attempts to explore thoughts beyond the realms of language. The key term for this chapter is semiosis. According to Kohn, any living organism will exhibit characteristics of forgetting and remembering which fosters semiotic change in the living being (76). Semiosis is what differentiates living beings from non-living beings. Forests, as living beings, have a lineage of the past, present, and futurity while non-living beings like snowflakes exist just for themselves (77). Semiotic growth in living beings serves as proof of thinking that non-human living beings engage in. Thinking is an inevitable and generalizable condition of all living beings in order for them to semiotically grow with their environment. This chapter is particularly interesting in light of the popular idiom “I think therefore I am.” While scholar Kenneth Morrison disposes of the term in favor of “I relate therefore I am” in his article “Animism and a Proposal for a Post-Cartesian Anthropology,” Kohn extends the definition of thought to all living beings. I believe the chapter would have been made more interesting had Kohn engaged in Rene Descartes’ “I think therefore I am” to link Kohn’s theory of thought to the popular idiom engrained in our (Western culture’s) ontology.
If the two chapters I mentioned above were theory-based in order to lay the groundwork for the book, the remainder of the book is more evenly balanced in terms of intertwining ethnography with ontological theory. In Chapters Three (Soul Blindness) and Four (Trans-Species Pidgins), Kohn incorporates his first chapter claim on human relationality to nature, and second chapter assertion that all living beings think, into Amazon Avila context. For Avila, death is only a way that the self surpasses the embodied limitations (105). Selves exist beyond physical death because beings have souls (105). Kohn supports such analysis by discussing “Aya,” the dead and soulless beings who lost connection with living humans (112). Not all dead humans become Aya, most maintain their souls and go to the forest master’s underground domain where the dead beings with souls take on different physical shapes and can interact with their living human relatives (110). Dead beings are not the only ones at risk of being alienated with their souls, living humans are just as likely to lose connection with souls. The “cosmic soul-blindness” makes one lose connection with other souls, and “radical soul blindness” makes one become blind to one’s own soul (130). Beings who maintain such soul-blind state may become the odd-one-out in the grand scheme of semiotic growth that all living beings partake in. Such alienation inevitably leads to ultimate death or extinction of the being.
Through a more detailed analysis of connection through souls in Chapter Four, Kohn notes of clear hierarchical order among Avila inter-species context which is not an ethically condemnatory practice but a reasonable practice born out of the Avila problem of maintaining a connection with others but also not losing oneself in the connection. Clear hierarchy exists between dogs, humans, and spirits of Avila with dogs coming at the bottom, humans in the middle, and spirits at the very top (144). Unlike many other hierarchies in Western society such as class and gender hierarchy, this particular Avila natural hierarchy, in Kohn’s observation, is not morally despicable because morality rises from symbolic language (133). Therefore, morality is confined to the human domain; the ethics used in human society cannot be utilized in understanding natural order. Instead, the dog-human-spirit hierarchy symbolizes Avila (or perhaps all human) struggles to “negotiate the tension between It and Thou” (152). In order for Avila to address the dogs through trans-species pidgin, Avila raise the dogs above the “it” status, but if humans address dogs as Thou or vice versa, humans fall to the ranks of the dog. Such precariousness represents Avila understanding of human location in nature. If a reader unfamiliar with Martin Buber’s I and Thou read this chapter, I believe this chapter would be quite difficult to comprehend. Although Buber’s theories are integral to the chapter at hand, besides an epigraph at the beginning of the chapter, Kohn does not spend much time in describing Buber’s theories.
Finally, in the two final chapters of the book, Eduardo Kohn makes, shall I say, much more overtly politically nuanced claims. While Chapter five: Form’s Effortless Efficacy expands Kohn theories via Amazonian colonial rubber industry practices, Chapter Six: The Living Future (and the imponderable weight of the dead) extrapolates on Chapter Three to make a final push to support Kohn’s claim that links us to the past and future as well as other non-human living beings. Form is the word Kohn uses to describe patterns that emerge from ways of thought (158). Like icons and indices, or thought for that matter, form does not just belong to humans. Amazon rubber trees have their own form; because of parasites that target rubber trees, the trees are widely distributed throughout the Amazon, not just clumped together in patches (161). In fact, non-human beings all have their own forms which are amplified by the ways humans or other non-humans use such form to their own benefit (225). Beings’ (especially human beings’) distinctive way of thinking, which leads to particular forms, makes one blind to other forms of life as well as our own form which constrains us from seeing other ways of living (185). Therefore, in Chapter Six, in a beautifully written sentence, Kohn summarizes the stakes of this book as going into the realm of the living into the world of spirit masters in hopes that we can better understand what continuity and growth means so that we can find better ways of living (196).
How Forests Think: Toward an Anthropology Beyond the Human is a critical and insightful read for anyone interested in understanding human position in the larger ecological context. Although the book is theoretically dense and difficult to get through because each consecutive chapter builds on the previous chapters’ theories, the book has the potential of being a reference for wide range of folks from environmental activists and anthropologists to politicians. How Forests Think: Toward an Anthropology Beyond the Human is also applicable for readers who just want to find their position in the vast array of beings that crowded the past, interact with us in the present, and will arrive in the future. The book may be more difficult to understand than a common self-help book, but for anyone willing to spend serious time and thought into the issues that I described throughout this review, this is the book for you.
