The essays in this volume explore some of the disconcerting realities of fanaticism, by analyzing its unique dynamics, and considering how it can be productively confronted. The book features both analytic and continental philosophical approaches to fanaticism. Working at the intersections of epistemology, philosophy of emotions, political philosophy, and philosophy of religion, the contributors address a range of questions related to this increasingly relevant, yet widely neglected topic. What are the distinctive features of fanaticism? What are its causes, motivations, and reasons? In what ways, if at all, is fanaticism epistemically, ethically, and politically problematic? And how can fanaticism be combatted or curtailed? The Philosophy of Fanaticism will be of interest to scholars and advanced students working in epistemology, philosophy of religion, philosophy of emotions, moral psychology, and political philosophy.

A genealogy of fanaticism—unearthing its long history, before it became a tool in the Clash of Civilizations It is commonplace to hear fanaticism described as a deviant or extreme variant of an already irrational set of religious beliefs, an assertion that helps to demonize convictions outside political orthodoxy. Alberto Toscano’s compelling and erudite counter-history explodes this accepted convention by exploring the critical role fanaticism played in the formation of modern politics and the liberal state. Showing how fanaticism results from a failure to formulate an adequate emancipatory politics, this illuminating history sheds new light on an idea that continues to dominate debates about faith and secularism. This expanded edition includes new material that revisits the idea of fanaticism as it operates at the limits of the liberal political imaginary, highlighting its relation to fraternal violence, political purity and the refusal of compromise, as well as its centrality to times of social crisis and international conflict.

Voltaire called fanaticism the "monster that pretends to be the child of religion". Philosophers, politicians, and cultural critics have decried fanaticism and attempted to define the distinctive qualities of the fanatic, whom Winston Churchill described as "someone who can’t change his mind and won’t change the subject". Yet despite fanaticism’s role in the long history of social discord, human conflict, and political violence, it remains a relatively neglected topic in the history of philosophy. In this outstanding inquiry into the philosophical history of fanaticism, a team of international contributors examine the topic from antiquity to the present day. Organized into four sections, topics covered include: Fanaticism in ancient Greek, Indian, and Chinese philosophy; Fanaticism and superstition from Hobbes to Hume, including chapters on Locke and Montesquieu, Shaftesbury, and Hutcheson; Kant, Germaine de Stael, Hegel, Nietzsche, William James, and Jorge Portilla on fanaticism; Fanaticism and terrorism; and extremism and gender, including the philosophy and morality of the "manosphere"; Closed-mindedness and political and epistemological fanaticism. Spanning themes from superstition, enthusiasm, and misanthropy to the emotions, purity, and the need for certainty, Fanaticism and the History of Philosophy is a landmark volume for anyone researching and teaching the history of philosophy, particularly ethics and moral philosophy. It is also a valuable resource for those studying fanaticism in related fields such as religion, the history of political thought, sociology, and the history of ideas.

As the post-WWII liberal democratic consensus comes under increasing assault around the globe, Zachary R. Goldsmith investigates a timely topic: the reemergence of fanaticism. His book demonstrates how the concept of fanaticism, so often flippantly invoked with little forethought, actually has a long history stretching back to ancient times. Tracing this history through the Reformation and the Enlightenment to our present moment of political extremism run amok, Goldsmith offers a novel account of fanaticism, detailing its transformation from a primarily religious to a political concept around the time of the French Revolution. He draws on the work of Immanuel Kant, Edmund Burke, and Fyodor Dostoevsky—all keen observers of fanaticism, and especially its political variant—in order to explore this crucial moment in the development of political fanaticism. Examining conceptualizations of fanaticism from different geographical, political, temporal, and contextual backgrounds, Goldsmith reveals how the concept has changed over time and resists easy definition. Nevertheless, his analysis of the writings of key figures from the tradition of political thought regarding fanaticism yields a complex and nuanced understanding of the concept that allows us to productively identify and observe its most salient characteristics: irrationality, messianism, the embrace of abstraction, the desire for novelty, the pursuit of perfection, a lack of limits in politics, the embrace of violence, certainty, passion, and its perennial attraction to intellectuals. Goldsmith’s political-philosophical history of fanaticism offers us an argument and warning against fanaticism itself, demonstrating that fanaticism is antidemocratic, illiberal, antipolitical, and never necessary.

We may think we know what defines religious fanaticism: violent action undertaken with dogmatic certainty. But the term fanatic, from the European Reformation to today, has never been a stable one. Then and now it has been reductively defined to justify state violence and to delegitimize alternative sources of authority. Unknowing Fanaticism rejects the simplified binary of fanatical religion and rational politics, turning to Renaissance literature to demonstrate that fanaticism was integral to how both modern politics and poetics developed, from the German Peasants’ Revolt to the English Civil War. The book traces two entangled approaches to fanaticism in this long Reformation moment: the targeting of it as an extreme political threat and the engagement with it as a deep epistemological and poetic problem. In the first, thinkers of modernity from Martin Luther to Thomas Hobbes and John Locke positioned themselves against fanaticism to pathologize rebellion and abet theological and political control. In the second, which arose alongside and often in response to the first, the poets of fanaticism investigated the link between fanatical self-annihilation—the process by which one could become a vessel for divine violence—and the practices of writing poetry. Edmund Spenser, John Donne, and John Milton recognized in the fanatic’s claim to be a passive instrument of God their own incapacity to know and depict the origins of fanaticism. Yet this crisis of unknowing was a productive one. It led these writers to experiment with poetic techniques that would allow them to address fanaticism’s tendency to unsettle the boundaries between human and divine agency and between individual and collective bodies. These poets demand a new critical method, which this book attempts to model: a historically-minded and politicized formalism that can attend to the complexity of the poetic encounter with fanaticism.

The planet is sick. Human beings are guilty of damaging it. We have to pay. Today, that is the orthodoxy throughout the Western world. Distrust of progress and science, calls for individual and collective self-sacrifice to ‘save the planet’ and cultivation of fear: behind the carbon commissars, a dangerous and counterproductive ecological catastrophism is gaining ground. Modern society’s susceptibility to this kind of thinking derives from what Bruckner calls “the seductive attraction of disaster,” as exemplified by the popular appeal of disaster movies. But ecological catastrophism is harmful in that it draws attention away from other, more solvable problems and injustices in the world in order to focus on something that is portrayed as an Apocalypse. Rather than preaching catastrophe and pessimism, we need to develop a democratic and generous ecology that addresses specific problems in a practical way.

The idea of fanaticism as a deviant or extreme variant of an already irrational set of religious beliefs is today invoked by the West in order to demonize and psychologize any non-liberal politics. Alberto Toscano's compelling and erudite counter-history explodes this accepted interpretation in exploring the critical role fanaticism played in forming modern politics and the liberal state. Tracing its development from the traumatic Peasants' War of early sixteenth-century Germany to contemporary Islamism, Toscano tears apart the sterile opposition of 'reasonableness' and fanaticism. Instead, in a radical new interpretation, he places the fanatic at the very heart of politics, arguing that historical and revolutionary transformations require a new understanding of his role. Showing how fanaticism results from the failure to formulate an adequate emancipatory politics, this illuminating history sheds new light on an idea that continues to dominate debates about faith and secularism.
