In the rich history of political philosophy, great minds have sought to define the nature and extent of human freedom, with careful justifications offered for the principles proposed. This tradition experienced a heightened degree of enthusiastic intensity upon the publication of On Liberty in England during the nineteenth century.
In this, his most powerful essay, John Stuart Mill defends individual liberty against both social and political encroachment, by daring to suggest that lines of demarcation be drawn to outline the proper role of government with respect to individual freedom....

During his long life (1872-1970) Bertrand Russell was one of a handful of social thinkers, let alone internationally recognized philosophers, whose views on contemporary issues won for him a devoted and supportive audience on the one hand and a host of vituperative critics on the other. Russell's revolutionary writings frequently placed him in the center of controversy with conservatives and all those who were unwilling to consider moral questions from a rational rather than an emotional stance.
Al Seckel has compiled an exhaustive collection of Russell's very best and most...

Communism as a political movement attained global importance after the Bolsheviks toppled the Russian Czar in 1917. After that time the works of Karl Marx and Frederick Engels, especially the influential Communist Manifesto (1848), enjoyed an international audience. The world was to learn a new political vocabulary peppered with "socialism," "capitalism," "the working class," "the bourgeoisie," "labor theory of value," "alienation," "economic determinism," "dialectical materialism," and "historical materialism." Marx's economic analysis of history has been a powerful legacy, the effects of...

All civilized societies share a common desire for internal order and security. For this reason, among others, moral codes and legal structures are developed to give form to social belief systems, to regulate interpersonal relations, and to promulgate ideals of appropriate behavior. But what should society or individuals do when the compelling dictates of personal conscience conflict strongly with statutory law? Can the morality of some be visited upon the rest of society by giving it the authority and power of law? Are there principles that go beyond legal jurisdiction to justify acts of...

As the indisputable father of Western philosophy, Socrates stands as the archetype of free inquiry and intellectual honesty throughout history. He dared to explore the minds of men, to analyze the content of cherished beliefs, and to distinguish knowledge and truth from opinion. This philosophical gadfly irritated the people of Athens, who tried him for corrupting their youth, and subsequently sentenced him to death for his "crime."

In these four short works by Plato, we come to experience the full range of Socrates' penetrating mind. In the Euthyphro, Socrates searches after the truth...

Throughout history, but most especially during the eighteenth-century Enlightenment, great minds of philosophy grappled with two thorny questions: What are the objects of knowledge? and How do we come to know them? Using the revealing dialogue technique, Berkeley shakes the very ground of those who believe that something called matter exists to support the sensible qualities we perceive. In his critique of this view, Berkeley argues for ideas in the mind as the only true reality about which one can have knowledge. His arguments for these conclusions, and for the ultimate foundation of all...

In this, one of the most influential works of the post-Hegelian era, Feuerbach captures the synthesis that emerges from the dialectical process of a transcending Godhead and the rational and material world.

In understanding the true nature of what it means to be fully human, Feuerbach contends that we come face to face with the essence of Christian theology: human beings investing ordinary concepts with divine meaning and significance. The true danger to humanity occurs when theology is given the force of dogma and doctrine. Losing sight of its anthropological underpinnings and dependence...

The twentieth century has witnessed the blossoming of Western culture: new technology; communications and transportation systems; social, political, educational, agricultural, and medical advances. But with these changes have come the strains and tensions of conflicting interests, desires, and values within the community. John Dewey, one of America's most prolific writers of popular philosophy, believed that humankind could keep a firm hold on its destiny only if the critical intelligence of scientific method and its democratic counterpart were emphasized and promoted. Freedom of inquiry,...

Ever since humankind raised its head toward the heavens in search of universal understanding and spiritual fulfillment, wars, pogroms, persecution, prejudice, and contempt have been the means of resolving the many and varied disagreements that have arisen over matters religious.
In his Letter Concerning Toleration, Locke offers a compelling plea for freedom of conscience and religious expression. He outlines the limits of social and political incursion into the realm of personal belief or non-belief, discusses the dangers of mixing church and state, and strikes hard at those who would use...

Like many cultures then and now, the early Greeks pondered the nature of the soul. Originally conceived as a kind of ghost, surviving in a bloodless existence after the death of the body, the soul was defined by later philosophers - notably the Pythagoreans and Plato - as an immaterial divine being temporarily "imprisoned" in the body. True knowledge was gained not through the senses but from contemplation of external Ideas that were, like the soul itself, immaterial and immortal.
A reformulation as well as a criticism of earlier thinkers, Aristotle's De Anima describes soul and body as...
