"Hayles draws from her vast knowledge of both the humanities and the sciences to create this unique book…and explores a broad range of interdisciplinary theories and research findings in a continuous, seamless fashion…Expansive thought is evident throughout this small volume, with endless topics for future exploration. This text is a suitable companion volume to the author’s other works, interdisciplinary collections, and consciousness studies collections…Highly recommended.”

“Traditionally, we have associated cognition with consciousness and hence only with human beings. Unthought provides evidence from neuroscience, literary studies, economics, urban planning, robotics, computer science, and other fields to demonstrate that this narrow view is not only restrictive but dangerous. Hayles shows that if we think of cognition as pattern recognition and the capacity to respond to environmental changes, then most living things and many technical devices are cognizers. This cutting-edge, one-of-a-kind book offers a model of how to mediate between science and philosophy in an intelligent and respectful way.”

Laura Otis, author of Rethinking Thought: Inside the Minds of Creative Scientists and Artists

“No one has done more to integrate the two cultures than Katherine Hayles, and this volume is truly a signature achievement. Here she rethinks cognition, building an intricate theoretical assemblage that includes the new materialisms, neuroscience, and cognitive biology and opens up her recent analyses of ‘how we think’ to an entire planetary cognitive ecology that is as expansive as it is technically precise. It is also, importantly, deeply ethical, at a moment when the stakes for the humanities, and the world, are particularly high. Unthought marks a brilliant addition to Hayles’s astonishing corpus—and it is surely destined to become part of our conscious and critical thought.”

Rita Raley, author of Tactical Media

“Hayles breaks with anthropocentric views of cognition with a framework that enmeshes biological and technical cognition. On offer here is a paradigm shift in how we think in relation to planetary cognitive ecologies, how we analyze the operations and ethical implications of human-technical assemblages, and how we imagine the role that the humanities can and should play in assessing these effects.”

Tim Lenoir, coauthor of The Military-Entertainment Complex

"The book compellingly suggests that many domains of science and society can be better understood—and more effectively engaged—by attending to the distributed systems of cognition that are already right there but not yet fully in the line of sight...But more than just filling in what has been omitted, Hayles proposes a reorientation or re-cognition, a revitalized outlook on what has so far been unthought in these fields...As Hayles demonstrates in her vivid technical discussions and bold theoretical formulations, the conditions for this radically altered way of understanding are already here."

Science Fiction Studies

"Unthought presents readers with a technically and theoretically rigorous take on what many new materialists refer to as distributed agency. . . . Readers familiar with Hayles’ work will recognize in Unthought a resumption of her interest in the significance of human or posthuman embodiment in the face of technological forces that seem to dematerialize subjectivity."

"A remarkable, ambitious and far-reaching book...of the utmost importance for literary scholars interested in interdisciplinary thought."
