On Drugs: Psychedelics, Philosophy, and the Nature of Reality

Liveright

September 13, 2025

On Drugs blends memoir, investigative reporting, and philosophical inquiry as Smith-Ruiu explores the profound impact of psychedelics on the mind and human consciousness. Drawing on a broad range of intellectual history and his personal experiences as “an articulate guinea pig,” he delves into how these substances challenge assumptions about reality, the self, and existence. 

Scenes of Attention: Essays on Mind, Time, and the Senses

Columbia University Press

November 14, 2023

Amid mounting concern about digital mediation of experience, the rise of “surveillance capitalism,” and the commodification of attention, Scenes of Attention deepens the thinking that is needed to protect the freedom of attention and the forms of life that make it possible.

The Internet Is Not What You Think It Is: A History, a Philosophy, a Warning

Princeton University Press

March 22, 2022

Combining the sweep of intellectual history with the incisiveness of philosophy, The Internet Is Not What You Think It Is cuts through our daily digital lives to give a clear-sighted picture of what the internet is, where it came from, and where it might be taking us in the coming decades.

In Search Of The Third Bird: Exemplary Essays from The Proceedings of ESTAR(SER), 2001–2021

Strange Attractor Press

December 14, 2021

A great deal of uncertainty—and even some genuine confusion—surrounds the origin, evolution, and activities of the so-called Avis Tertia or “Order of the Third Bird.” Sensational accounts of this “attentional cult” emphasize histrionic rituals, tragic trance-addictions, and the covert dissemination of obscurantist ontologies of the art object. Hieratic, ecstatic, and endlessly evasive, the Order attracts sensual misfits and cabalistic aesthetes—both to its ranks, and to its scholarship.

Anton Wilhelm Amo's Philosophical Dissertations on Mind and Body

Oxford University Press

July 15, 2020

The most thorough treatment of Amo's life and work ever published. For the first time, an accurate translation with the full annotation (including tracking down the texts that Amo refers to) needed for understanding Amo's argument. A full discussion of Amo's immediate intellectual context; of the institutional context of early modern dissertations and disputations (whose conventions make them very difficult to follow without a guide); and of the early modern debates about mind and body, causation, and representation, in which Amo is staking out his own position.

Irrationality: A History of the Dark Side of Reason

Princeton University Press

April 2, 2019

Rich and ambitious, Irrationality ranges across philosophy, politics, and current events. Challenging conventional thinking about logic, natural reason, dreams, art and science, pseudoscience, the Enlightenment, the internet, jokes and lies, and death, the book shows how history reveals that any triumph of reason is temporary and reversible, and that rational schemes, notably including many from Silicon Valley, often result in their polar opposite. The problem is that the rational gives birth to the irrational and vice versa in an endless cycle, and any effort to permanently set things in order sooner or later ends in an explosion of unreason. Because of this, it is irrational to try to eliminate irrationality. For better or worse, it is an ineradicable feature of life.

Embodiment: A History

Oxford University Press

June 30, 2017

Ultimately, to what extent can natural science help us to resolve philosophical questions about embodiment, many of which are vastly older than the particular scientific research programs we now believe to hold the greatest promise for revealing to us the bodily basis, or the ultimate physical causes, of who we really are?

Nature, Human Nature, and Human Difference: Race in Early Modern Philosophy

Princeton University Press

March 14, 2017

People have always been xenophobic, but an explicit philosophical and scientific view of human racial difference only began to emerge during the modern period. Why and how did this happen? Surveying a range of philosophical and natural-scientific texts, dating from the Spanish Renaissance to the German Enlightenment, Nature, Human Nature, and Human Difference charts the evolution of the modern concept of race and shows that natural philosophy, particularly efforts to taxonomize and to order nature, played a crucial role.

The Leibniz-Stahl Controversy

Yale University Press

August 9, 2016

The correspondence between the eighteenth-century mathematician and philosopher G. W. Leibniz and G. E. Stahl, a chemist and physician at the court of King Friedrich Wilhelm I of Prussia, known as the Leibniz-Stahl Controversy, is one of the most important intellectual contributions on theoretical issues concerning pre-biological thinking. Editors François Duchesneau and Justin E. H. Smith offer readers the first fully annotated English translation of this fascinating exchange of philosophical views on divine action, the order of nature, causality and teleology, and the soul-body relationship.

The Life Sciences in Early Modern Philosophy

Oxford University Press

January 6, 2014

The contributions to this volume are organized in accordance with the particular problems that living beings and living nature posed for early modern philosophy: the problem of life in general, whether it constitutes something ontologically distinct at all, or whether it can ultimately be exhaustively comprehended "in the same manner as the rest"; the problem of the structure of living beings, by which we understand not just bare anatomy but also physiological processes such as irritability, motion, digestion, and so on; the problem of generation, which might be included alongside digestion and other vital processes, were it not for the fact that it presented such an exceptional riddle to philosophers since antiquity, namely, the riddle of coming-into-being out of -- apparent or real -- non-being; and, finally, the problem of natural order.

Philosophy and Its History: Aims and Methods in the Study of Early Modern Philosophy

Oxford University Press

July 5, 2013

This volume collects contributions from leading scholars of early modern philosophy from a wide variety of philosophical and geographic backgrounds. The distinguished contributors offer very different, competing approaches to the history of philosophy. Many chapters articulate new, detailed methods of doing history of philosophy. These present conflicting visions of the history of philosophy as an autonomous sub-discipline of professional philosophy. Several other chapters offer new approaches to integrating history into one's philosophy by re-telling the history of recent philosophy. A number of chapters explore the relationship between history of philosophy and history of science.

Divine Machines: Leibniz and the Sciences of Life

Princeton University Press

May 1, 2011

Though it did not yet exist as a discrete field of scientific inquiry, biology was at the heart of many of the most important debates in seventeenth-century philosophy. Nowhere is this more apparent than in the work of G. W. Leibniz. In Divine Machines, Justin Smith offers the first in-depth examination of Leibniz’s deep and complex engagement with the empirical life sciences of his day, in areas as diverse as medicine, physiology, taxonomy, generation theory, and paleontology. He shows how these wide-ranging pursuits were not only central to Leibniz’s philosophical interests, but often provided the insights that led to some of his best-known philosophical doctrines.

The Problem of Animal Generation in Early Modern Philosophy

Cambridge University Press

August 22, 2006

In this volume Smith examines the early modern science of generation, which included the study of animal conception, heredity, and fetal development. Analyzing how it influenced the contemporary treatment of traditional philosophical questions, it also demonstrates how philosophical pre-suppositions about mechanism, substance, and cause informed the interpretations offered by those conducting empirical research on animal reproduction. Composed of essays written by an international team of leading scholars, the book offers a fresh perspective on some of the basic problems in early modern philosophy. It also considers how these basic problems manifested themselves within an area of scientific inquiry that had not previously received much consideration by historians of philosophy.
