Freedom of thought is one of the great and venerable notions of Western thought, often celebrated in philosophical texts – and described as a crucial right in American, European, and International Law, and in that of other jurisdictions. What it means more precisely is, however, anything but clear; surprisingly little writing has been devoted to it. In the past, perhaps, there has been little need for such elaboration. As one Supreme Court Justice stressed, “[f]reedom to think is absolute of its own nature” because even “the most tyrannical government is powerless to control the inward workings of the mind.” But the rise of brain scanning, cognition enhancement, and other emerging technologies make this question a more pressing one. This volume provides an interdisciplinary exploration of how freedom of thought might function as an ethical principle and as a constitutional or human right. It draws on philosophy, legal analysis, history, and reflections on neuroscience and neurotechnology to explore what respect for freedom of thought (or an individual’s cognitive liberty or autonomy) requires.

In this volume the authors explore the landscape of thought on the ethical and policy implications of Brain Computer Interface (BCI) technology. BCI technology is a promising and rapidly advancing research area. Recent developments in the technology, based on animal and human studies, allow for the restoration and potential augmentation of faculties of perception and physical movement, and even the transfer of information between brains. Brain activity can be interpreted through both invasive and non-invasive monitoring devices, allowing for novel, therapeutic solutions for individuals with disabilities and for other non-medical applications. However, a number of ethical and policy issues have been identified from the use of BCI technology, with the potential for near-future advancements in the technology to raise unique new ethical and policy questions that society has never grappled with before. The volume has three parts: 1) Past, Present and Future of BCI technology, 2) Ethical and Philosophical Issues and 3) Legal and Policy Implications. The rich and detailed picture of the field of BCI ethics with contributors from various fields and backgrounds, from academia and from the commercial sphere may serve as an introductory textbook into the neuroethics of BCI, or as a resource for neuroscientists, engineers, and medical practitioners to gain additional insight into the ethical and policy implications of their work.

In this masterful work, both an illumination of Kant’s thought and an important contribution to contemporary legal and political theory, Arthur Ripstein gives a comprehensive yet accessible account of Kant’s political philosophy. Ripstein shows that Kant’s thought is organized around two central claims: first, that legal institutions are not simply responses to human limitations or circumstances; indeed the requirements of justice can be articulated without recourse to views about human inclinations and vulnerabilities. Second, Kant argues for a distinctive moral principle, which restricts the legitimate use of force to the creation of a system of equal freedom. Ripstein’s description of the unity and philosophical plausibility of this dimension of Kant’s thought will be a revelation to political and legal scholars. In addition to providing a clear and coherent statement of the most misunderstood of Kant’s ideas, Ripstein also shows that Kant’s views remain conceptually powerful and morally appealing today. Ripstein defends the idea of equal freedom by examining several substantive areas of law—private rights, constitutional law, police powers, and punishment—and by demonstrating the compelling advantages of the Kantian framework over competing approaches.

This book examines the legal boundaries of non-consensual brain-reading in criminal justice. Focusing on human rights such as privacy and freedom of thought and expression, the book informs lawyers and ethicists debating the legal implications of emerging neurotechnology and advises policymakers and judges in specifying the law to neurotechnology.
