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,...

Throughout history philosophers have sought to define, understand, and delineate concepts important to human well-being. One such concept is "knowledge." Many philosophers believed that absolute, certain knowledge, is possible--that the physical world and ideas formulated about it could be given solid foundation unaffected by the varieties of mere opinion.

Sextus Empiricus stands as an example of the "skeptic" school of thought whose members believed that knowledge was either unattainable or, if a genuine possibility, the conditions necessary to achieve it were next to impossible to...

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...

Hegel's Philosophy of History stands as a fascinating example of this influential German thinker's efforts to capture the multidimensional character of reality within a broad theoretical framework.
Hegel draws upon many of his well-known concepts - Mind, Spirit, dialectical method (thesis-negation-synthesis), the relation of the whole to its parts, and how rational human beings relate to that which transcends their individuality. History is the evolution of freedom as societies and cultures acquire a greater awareness of, and appreciation for, the interaction of individuals with the...

Metaphysics is the study of existence at the highest level of generality. It is traditionally characterised as the study of "being qua being" - of being in general rather than specifically of this or that sort. Accordingly, the salient task of the field is to achieve a clearer understanding of the concepts and principles of being, existence, and reality. As such, metaphysics has been an established sector of philosophy since the time of Aristotle's initial systematisation of the subject in the fourth century B.C.E.In line with tradition, distinguished philosopher Nicholas Rescher presents key...

John Dewey, one of America's greatest popular philosophers and educators, emphasizes the importance of critical thinking and the vital role education should play.
In this progressive work, written more than 80 years ago, Dewey, recognizing that we are born with the ability to think, argues that the educator's fundamental role is to train us to think well. At a time when America is lamenting the lack of solid training in the sciences at the elementary and secondary levels, Dewey's enthusiastic correlation between the scientific mind and the natural attitude of childhoodmarked by curiosity,...

"Nothing is more curiously enquired after . . . than the causes of every phenomenon. . . . We] push on our enquiries, till we arrive at the original and ultimate principle. . . . This is our aim in all our studies and reflections."

These words sum up David Hume's plan: To discover the fundamental principles at work in the nature and extent of human knowledge, and in so doing to gain a clearer understanding of our perception, ideas (e.g. of cause and effect), impressions, beliefs, passions, virtues, and vices. Hume's piercing critique and relentless analysis make this truly one of the...

Analyzing the poetic genres of his own day, particularly epic and tragedy, Aristotle sets forth a comprehensive theory of the poetic art. In this seminal and highly influential work of ancient literary criticism, Aristotle discusses poetry's esthetic function as well as its emotional value, revealing at the same time the basic principles of literary art and giving practical hints to the poet.
