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.

The authoritative text on the libertarian political position In recent years, libertarian impulses have increasingly influenced national and economic debates, from welfare reform to efforts to curtail affirmative action. Murray N. Rothbard's classic The Ethics of Liberty stands as one of the most rigorous and philosophically sophisticated expositions of the libertarian political position. Rothbard’s unique argument roots the case for freedom in the concept of natural rights and applies it to a host of practical problems. And while his conclusions are radical—that a social order that strictly adheres to the rights of private property must exclude the institutionalized violence inherent in the state—Rothbard’s applications of libertarian principles prove surprisingly practical for a host of social dilemmas, solutions to which have eluded alternative traditions. The Ethics of Liberty authoritatively established the anarcho-capitalist economic system as the most viable and the only principled option for a social order based on freedom. This classic book’s radical insights are sure to inspire a new generation of readers.

Offering a new reading of Spinoza's masterpiece, Smith asserts that the 'Ethics' is a celebration of human freedom and its attendant joys and responsibilities and should be placed among the great founding documents of the Enlightenment.

From the groundbreaking author of The Second Sex comes a radical argument for ethical responsibility and freedom. In this classic introduction to existentialist thought, French philosopher Simone de Beauvoir’s The Ethics of Ambiguity simultaneously pays homage to and grapples with her French contemporaries, philosophers Jean-Paul Sartre and Maurice Merleau-Ponty, by arguing that the freedoms in existentialism carry with them certain ethical responsibilities. De Beauvoir outlines a series of “ways of being” (the adventurer, the passionate person, the lover, the artist, and the intellectual), each of which overcomes the former’s deficiencies, and therefore can live up to the responsibilities of freedom. Ultimately, de Beauvoir argues that in order to achieve true freedom, one must battle against the choices and activities of those who suppress it. The Ethics of Ambiguity is the book that launched Simone de Beauvoir’s feminist and existential philosophy. It remains a concise yet thorough examination of existence and what it means to be human.

This book reveals Marx’s moral philosophy and analyzes its nature. The author shows that there is an underlying system of ethics which runs the length and breadth of Marx’s thought. The book begins by discussing the methodological side of Marx’s ethics showing how Marx’s criticism of conventional morality and his views on historical materialism, determinism and ideology are compatible with having an ideological system of his own. In the light of contemporary social, moral and political philosophy the insights and defects of Marx’s major ethical themes are discussed.

Simone de Beauvoir published a number of philosophical essays and novels before writing The Second Sex. The most important of these was The Ethics of Ambiguity, in which she argues that one's freedom is always intertwined with that of others. The Bonds of Freedom examines de Beauvoir's ideas on ethics, demonstrating her importance in contemporary philosophy.
