What can we learn from a high-country valley tucked into an isolated corner of Rocky Mountain National Park? In this pathbreaking book, Thomas Andrews offers a meditation on the environmental and historical pressures that have shaped and reshaped one small stretch of North America, from the last ice age to the advent of the Anthropocene and the latest controversies over climate change.

Large-scale historical approaches continue to make monumental contributions to our understanding of the past, Andrews writes. But they are incapable of revealing everything we need to know about the interconnected workings of nature and human history. Alongside native peoples, miners, homesteaders, tourists, and conservationists, Andrews considers elk, willows, gold, mountain pine beetles, and the Colorado River as vital historical subjects. Integrating evidence from several historical fields with insights from ecology, archaeology, geology, and wildlife biology, this work simultaneously invites scientists to take history seriously and prevails upon historians to give other ways of knowing the past the attention they deserve.

From the emergence and dispossession of the Nuche—“the People”—who for centuries adapted to a stubborn environment, to settlers intent on exploiting the land, to forest-destroying insect invasions and a warming climate that is pushing entire ecosystems to the brink of extinction, Coyote Valley underscores the value of deep drilling into local history for core relationships—to the land, climate, and other species—that complement broader truths. This book brings to the surface the critical lessons that only small and seemingly unimportant places on Earth can teach.

The idea that a new technology could challenge human intelligence is as old as the warning from Socrates and Plato that written language eroded memory. With the emergence of generative artificial intelligence programs, we find ourselves once again debating how a new technology might influence human thought and behavior. Researchers, software developers, and “visionary” tech writers even imagine an AI that will equal or surpass human intelligence, adding to a sense of technological determinism where humanity is inexorably shaped by powerful new machines. But among the hundreds of essays, books, and movies that approach the question of AI, few have asked how exactly scientists and philosophers have codified human thought and behavior. Rather than focusing on technical contributions in machine building, The Descent of Artificial Intelligence explores a more diverse cast of thinkers who helped to imagine the very kind of human being that might be challenged by a machine. Kevin Padraic Donnelly argues that what we often think of as the “goal” of AI has in fact been shaped by forgotten and discredited theories about people and human nature as much as it has been by scientific discoveries, mathematical advances, and novel technologies. By looking at the development of artificial intelligence through the lens of social thought, Donnelly deflates the image of artificial intelligence as a technological monolith and reminds readers that we can control the narratives about ourselves.
