This collection offers new essays by eminent scholars on Wittgenstein's third masterpiece, "On Certainty." Although Wittgenstein's language, and the problems he deals with--the nature of basic beliefs, epistemic foundationalism, knowledge, certainty, skepticism--are here much closer to traditional philosophy, the exploratory and nonlinear character of "On Certainty" make it a difficult work to penetrate. These essays probe deep into the work from four different approaches: the framework reading; the transcendental reading; the therapeutic reading; and the epistemic reading. This is the first collection ever devoted to "On Certainty," and will prove an invaluable tool to scholars and students of Wittgenstein who have thus far only fleetingly ventured beyond Philosophical Investigations.

Cybercrime is remarkably varied and widespread, and financial losses range from a few hundred dollars being extorted to multi-million dollar cyberfraud cases. Increasingly, cybercrime also involves the risk of terrorist attacks bringing down a major part of the Internet. Countries are discovering that it may be impossible for them to prosecute cybercriminals. Cybercrimes, unlike 'ordinary' crimes, are transnational in nature and it is often difficult to say just where they take place. This causes legal problems, since jurisdiction is usually still confined to the place where the crime was committed. A related issue is to what extent the police can investigate cybercrimes across borders, through the Internet: do they infringe the sovereignty of other countries? This book surveys how these issues in cybercrime jurisdiction are dealt with by countries around the world, including the US, Japan, Korea, India, Brazil, Chile, Australia, New Zealand, Italy, Germany, Belgium, Denmark, and the UK. A score of experts assess how well the laws of their countries and the Cybercrime Convention deal with transnational cybercrime, and how jurisdiction conflicts should be resolved. With this in-depth survey of views and practices of cybercrime jurisdiction, the authors hope to contribute to a more concerted international effort towards effectively fighting cybercrime. The book is therefore highly recommended to policy-makers, members of the judiciary, academics and practitioners.

This fascinating and timely book traces the emergence and evolution of cybercrime as an increasingly intransigent threat to society. Cybercrime: Criminal Threats from Cyberspace is intended to explain two things: what cybercrime is and why the average citizen should care about it. To accomplish that task, the book offers an overview of cybercrime and an in-depth discussion of the legal and policy issues surrounding it. Enhancing her narrative with real-life stories, author Susan W. Brenner traces the rise of cybercrime from mainframe computer hacking in the 1950s to the organized, professional, and often transnational cybercrime that has become the norm in the 21st century. She explains the many different types of computer-facilitated crime, including identity theft, stalking, extortion, and the use of viruses and worms to damage computers, and outlines and analyzes the challenges cybercrime poses for law enforcement officers at the national and international levels. Finally, she considers the inherent tension between improving law enforcement's ability to pursue cybercriminals and protecting the privacy of U.S. citizens.

This book explores the extraordinary difficulties a nation-state's law enforcement and military face in attempting to prevent cyber-attacks. In the wake of recent assaults including the denial of service attack on Estonia in 2007 and the widespread use of the Zeus Trojan Horse software, Susan W. Brenner explores how traditional categories and procedures inherent in law enforcement and military agencies can obstruct efforts to respond to cyberthreats. Brenner argues that the use of a territorially-based system of sovereignty to combat cyberthreats is ineffective, as cyberspace erodes the import of territory. This problem is compounded by the nature of cybercrime as a continually evolving phenomenon driven by rapid and complex technological change. Following an evaluation of the efficacy of the nation-state, the book goes on to explore how individuals and corporations could be integrated into a more decentralized, distributed system of cyberthreat control. Looking at initiatives in Estonia and Sweden which have attempted to incorporate civilians into their cyber-response efforts, Brenner suggests that civilian involvement may mediate the rigid hierarchies that exist among formal agencies and increase the flexibility of any response. This book will be of great interest to students and researchers of information technological law and security studies.

As new technologies develop, terrorist groups are developing new methods of attack by using the Internet, and by using cyberspace as a battlefield, it has become increasingly difficult to discover the identity of attackers and bring them to justice. The seemingly limitless boundaries of cyberspace has allowed virtually anyone to launch an attack from a remote and anonymous location. But once these attacks occur, it raises several important questions; who should respond, and how?; how should nation-states effectively deal with a cyber-attack?; and will the United States and other nation-states be able to survive in a world where virtual boundaries are limitless?
In Cyberthreats: The Emerging Fault Lines of the Nation State Susan Brenner gives a thorough explanation of how military and law enforcement personnel respond to these attacks and why bringing cyber-terrorist to justice can be difficult and sometimes impossible.

This is the first collection of papers devoted to Ludwig Wittgenstein's cryptic but brilliant "On Certainty." This work, Wittgenstein's last, extends the thinking of his earlier, better known writings, and in so doing, makes the most important contribution to epistemology since Kant's "Critique of Pure Reason"--a claim the essays in this volume help to demonstrate. The essays have been grouped under four headings, reflecting current approaches to the work: the Framework, Transcendental, Epistemic, and Therapeutic readings.
