Concepts like extremism and radicalization are highly contested. Their definitions matter, because they influence how we study extremism and radicalization and, in the long run, how these are perceived in the public debate. Rather than adding more definitions, this book explores the underlying challenging conceptual issues in defining, interpreting, and operationalizing notions such as extremism, radicalization, fanaticism, and terrorism. It explores four crucial questions. First, how should each of these extreme phenomena be defined, and what are the desiderata in seeking definitions of each of them? Second, how should the project of defining and conceptualizing these phenomena be undertaken: in terms of necessary and sufficient conditions, or family resemblances, or common understandings in the public debate, or something else? Third, what is the role of normativity in defining these extreme phenomena, that is, the proper place of normative or even pejorative concepts and the normative framework of the researcher? Fourth and finally, how do the phenomena of extremism, fanaticism, fundamentalism, terrorism, and conspiracism relate to one another and to things such as apocalypticism, nationalism, cults, charisma, and state terror? Written by global, multidisciplinary experts, this text lays the conceptual groundwork that the other volumes in the Extreme Belief and Behavior Series will build on.

Terrorism has returned to the streets of Northern Ireland. In the years after the 1998 Real IRA bombing of Omagh, which killed 29 people, violent dissident Republican groups have re-emerged as a major security threat to a region that has been denied peace, stability, and prosperity for too long.Those responsible have many names. They are breakaways, splinter factions, spoilers, and "residual" terrorists. The Real IRA, Continuity IRA, and Óglaigh na hÉireann are only some of the groups now responsible for a growing wave of bombings, shootings, threats, and intimidation across Northern Ireland. Commonly known as "the dissidents," these are the rejectionists for whom there seems to be no negotiated settlement, no peace deal, no consensus solution that will convince them to accept the will of the majority of the people on the island of Ireland.Divided We Stand: The Strategy and Psychology of Ireland's Dissident Terrorists presents the results of meticulous research conducted by the International Center for the Study of Terrorism at the Pennsylvania State University. Since 2007, John Horgan, Director of the center, has led a research project to monitor the activities of Ireland's new terrorists. Drawing on one of the largest open-source militant databases ever assembled, Divided We Stand describes the activities, histories, motivations, psychology, and strategy of the small, dynamic, and rapidly evolving splinter groups that continue to erode peace, stability, and normalization in Northern Ireland.

Runner-up, 2025 Airey Neave Memorial Book Prize, Airey Neave TrustWhat makes a person want to become a terrorist? Who becomes involved in terrorism, and why? In what ways does participating in violent extremism change someone? And how can people become deradicalized?John Horgan—one of the world’s leading experts on the psychology of terrorism—takes readers on a globe-spanning journey into the terrorist mindset. Drawing on groundbreaking personal interviews as well as decades of research from psychologists and others, he traces the pathways that lead people into violent extremism and explores what happens to them as their involvement deepens. Horgan provides an up-to-date, evidence-based understanding of the patterns, motives, and mentalities of violent extremists from the Islamic State and al-Shabaab to white supremacists and incels. He argues that there is not a straightforward psychological profile of a terrorist, in part because of the great variety of today’s extremists, who are able to attract a more diverse pool of recruits than ever before. But even though there is no one-size-fits-all profile, psychological study can provide crucial insight into why and how people become terrorists.Accessible and nuanced, Terrorist Minds is an essential book for readers interested in what psychology can explain about extremist behavior.

As a writer for SCIENTIFIC AMERICAN, John Horgan has an unsurpassed window on contemporary science, routinely interviewing the scientific geniuses of our times, scientists such as Richard Dawkins, Murray Gell-Mann, Stephen Hawking, Karl Popper and Noam Chomsky. In THE END OF SCIENCE, Horgan displays his genius for getting these larger-than-life figures to be human, whilst also encouraging them to confront the very limits of knowledge. Have the big questions all been answered? Has all the knowledge worth pursuing become known? Will there be a final 'theory of everything' that signals the end? Horgan extracts surprisingly candid answers to these and other delicate questions as he discusses God, Star Trek, superstrings, quarks, consciousness and numerous other topics. In a time where scientific rationality is under fire from every quarter, THE END OF SCIENCE is a witty, thoughtful, profound and entertaining narrative which serves as both a critique of and a homage to modern science.

Irish Media: A Critical History maps the landscape of media in Ireland from the foundation of the modern state in 1922 to the present. Covering all principal media forms, print and electronic, in the Republic and in Northern Ireland, John Horgan shows how Irish history and politics have shaped the media of Ireland and, in turn, have been shaped by them.Beginning in a country ravaged by civil war, it traces the complexities of wartime censorship and details the history of media technology, from the development of radio to the inauguration of television in the 1950s and 1960s. It covers the birth, development and - sometimes - the death of major Irish media during this period, examining the reasons for failure and success, and government attempts to regulate and respond to change. Finally, it addresses questions of media globalisation, ownership and control, and looks at issues of key significance for the future.Horgan demonstrates why, in a country whose political divisions and economic development have given it a place on the world stage out of all proportion to its size, the media have been and remain key players in Irish history.

In The End of Science, John Horgan makes the case that the era of truly profound scientific revelations about the universe and our place in it is over. Interviewing scientific luminaries such as Stephen Hawking, Francis Crick, and Richard Dawkins, he demonstrates that all the big questions that can be answered have been answered, as science bumps up against fundamental limits. The world cannot give us a “theory of everything,” and modern endeavors such as string theory are “ironic” and “theological” in nature, not scientific, because they are impossible to confirm. Horgan’s argument was controversial in 1996, and it remains so today, still firing up debates in labs and on the internet, not least because—as Horgan details in a lengthy new introduction—ironic science is more prevalent than ever. Still, while Horgan offers his critique, grounded in the thinking of the world’s leading researchers, he offers homage, too. If science is ending, he maintains, it is only because it has done its work so well.

This book provides a unique insight into the ethical issues and dilemmas facing practitioners and researchers of terrorism and counterterrorism.Ethics play a central if, largely, unrecognised role in most, if not all, issues relevant to terrorism and political violence. These are often most noticeable regarding counterterrorism controversies, while often virtually absent from discussions about academic research practice. At a minimum, ethical issues as they relate to terrorism have rarely been explicitly addressed in a direct or comprehensive manner. The chapters in this edited volume draws on the experience of both practitioners and researchers to explore how a regard to ethical issues might influence and determine research and practice in counter terrorism, and in our understanding of terrorism. Ethics and Terrorism recognizes that there are conflicting and often irreconcilable perspectives from which to view terrorism and terrorism research. In calling for greater attention to these issues, the goal is not to resolve problems, but to explore and clarify the assumptions and dilemmas that underpin our understanding of the personal, institutional and societal ethical boundaries and constraints around terrorism and responses to it. This book will be of value to practitioners and researchers, and to policy makers and the broader interested community.The chapters in this book were originally published as a special issue of the journal Terrorism and Political Violence.
