"A Treatise Concerning the Principles of Human Knowledge" is one of Berkeley's best known works and in it Berkeley expounds upon this idea of subjective idealism, which in other words is the idea that all of reality, as far as humans are concerned, is simply a construct of the way our brains perceive and according to Berkeley no other sense of reality matters beyond that which we perceive.

    His great book, On Nature, the world's first coherent philosophical treatise and touchstone for Plato, Aristotle, and Marcus Aurelius, has long been lost to history-but its surviving fragments have for thousands of years tantalized our greatest thinkers, from Montaigne to Nietzsche, Heidegger to Jung.

    Everyone knows this. Each of us contributes his share. But we tend to take the situation for granted. Most people are rather confident of their ability to recognize bullshit and to avoid being taken in by it. So the phenomenon has not aroused much deliberate concern. We have no clear understanding of what bullshit is, why there is so much of it, or what functions it serves. And we lack a conscientiously developed appreciation of what it means to us. In other words, as Harry Frankfurt writes, "we have no theory."Frankfurt, one of the world's most influential moral philosophers, attempts to build such a theory here. With his characteristic combination of philosophical acuity, psychological insight, and wry humor, Frankfurt proceeds by exploring how bullshit and the related concept of humbug are distinct from lying. He argues that bullshitters misrepresent themselves to their audience not as liars do, that is, by deliberately making false claims about what is true. In fact, bullshit need not be untrue at all.Rather, bullshitters seek to convey a certain impression of themselves without being concerned about whether anything at all is true. They quietly change the rules governing their end of the conversation so that claims about truth and falsity are irrelevant. Frankfurt concludes that although bullshit can take many innocent forms, excessive indulgence in it can eventually undermine the practitioner's capacity to tell the truth in a way that lying does not. Liars at least acknowledge that it matters what is true. By virtue of this, Frankfurt writes, bullshit is a greater enemy of the truth than lies are.

    Austin was one of the leading philosophers of the twentieth century. The William James Lectures presented Austin's conclusions in the field to which he directed his main efforts on a wide variety of philosophical problems. These talks became the classic How to Do Things with Words.For this second edition, the editors have returned to Austin's original lecture notes, amending the printed text where it seemed necessary. Students will find the new text clearer, and, at the same time, more faithful to the actual lectures. An appendix contains literal transcriptions of a number of marginal notes made by Austin but not included in the text. Comparison of the text with these annotations provides new dimensions to the study of Austin's work.

    Sorel was a civil servant who fervently believed that only the clearest and most brutal expression of class war could effect lasting social change. This, his most important work, is a passionate outcry for the socialist overthrow of society.Reflections on Violence first appeared as a series of articles in Le Mouvement Socialiste in 1906; it appeared in book form two years later, and translations extended its influence around the world. Sorel addresses the factors underlying revolutionary movements and examines the roles of violence (the revolutionary denial of the existing social order) and force (the state's power of coercion). He further explores sources of political power, the weapons of revolutions — the insurrection and the general strike — and the significant role of "myths" in recruiting and motivating potential revolutionaries.

    

    Many prominent writers have acknowledged its influence on their work; students of intellectual history consider it a landmark; and the generation born after World War II considers Buber one of its prophets. Buber's main proposition is that we may address existence in two ways: (1) that of the "I" toward an "It," toward an object that is separate in itself, which we either use or experience; (2) that of the "I" toward "Thou," in which we move into existence in a relationship without bounds. One of the major themes of the book is that human life finds its meaningfulness in relationships. All of our relationships, Buber contends, bring us ultimately into relationship with God, who is the Eternal Thou.The need for a new English translation had been felt for many years. The old version was marred by many inaccuracies and misunderstandings, and its recurrent use of the archaic "thou" was seriously misleading. Professor Walter Kaufmann, a distinguished writer and philosopher in his own right who was close to Buber, retranslated the work at the request of Buber's family. He added a wealth of informative footnotes to clarify obscurities and bring the reader closer to the original and wrote an extensive prologue that opened up new perspectives on the book and on Buber's thought. This volume provided a new basis for all subsequent discussions of Buber.

    He is also one of its most controversial. The author of important books such as Animal Liberation, Practical Ethics, Rethinking Life and Death, and The Life You Can Save, he helped launch the animal rights and effective altruism movements and contributed to the development of bioethics. Now, in Ethics in the Real World, Singer shows that he is also a master at dissecting important current events in a few hundred words.In this book of brief essays, he applies his controversial ways of thinking to issues like climate change, extreme poverty, animals, abortion, euthanasia, human genetic selection, sports doping, the sale of kidneys, the ethics of high-priced art, and ways of increasing happiness. Singer asks whether chimpanzees are people, smoking should be outlawed, or consensual sex between adult siblings should be decriminalized, and he reiterates his case against the idea that all human life is sacred, applying his arguments to some recent cases in the news. In addition, he explores, in an easily accessible form, some of the deepest philosophical questions, such as whether anything really matters and what is the value of the pale blue dot that is our planet. The collection also includes some more personal reflections, like Singer’s thoughts on one of his favorite activities, surfing, and an unusual suggestion for starting a family conversation over a holiday feast.Provocative and original, these essays will challenge—and possibly change—your beliefs about a wide range of real-world ethical questions.

    Beginning with: "It was Sappho who first called eros 'bittersweet.' No one who has been in love disputes her. What does the word mean?", Carson examines her subject from numerous points of view and styles, transcending the constraints of the scholarly exercise for an evocative and lyrical meditation in the tradition of William Carlos William's Spring and All and William H. Gass's On Being Blue.

    It is universally recognized as the standard English version of Aristotle. This revised edition contains the substance of the original translation, slightly emended in light of recent scholarship; three of the original versions have been replaced by new translations; and a new and enlarged selection of Fragments has been added. The aim of the translation remains the same: to make the surviving works of Aristotle readily accessible to English speaking readers.

    Born into the Russian nobility, he renounced his hereditary rank in protest against Czarist oppression and fled to Western Europe. A colorful, charismatic personality, Bakunin quickly became central to the anarchism movement, and everyone involved either built upon or reacted to his ideas. Yet Bakunin, despite the power of his ideas, was primarily a man of action, and he wrote little. His only major work, God and the State, remained unfinished, although it is the torso of a giant.God and the State has been a basic anarchist and radical document for generations. It is one of the clearest statements of the anarchist philosophy of history: religion by its nature is an impoverishment, enslavement, and annihilation of humanity. It is the weapon of the state. It must be smashed, according to Bakunin, before the right of self-determination can be possible. As an introduction to anarchist thought, a manifesto of atheism, or as a summing-up of the thoughts of Bakunin, God and the State remains a mind-opening experience, even for those basically unsympathetic to its premise.

    In it, Berger and Luckmann reformulate the task of the sociological subdicipline that, since Max Scheler, has been known as the sociology of knowledge.

    From Plato to Christianity, from the Enlightenment to Nietzsche, the Western tradition has been based on arrogant and erroneous beliefs about human beings and their place in the world. Philosophies such as liberalism and Marxism think of humankind as a species whose destiny is to transcend natural limits and conquer the Earth. Even in the present day, despite Darwin's discoveries, nearly all schools of thought take as their starting point the belief that humans are radically different from other animals. John Gray argues that this humanist belief is an illusion. The aim of Straw Dogs is to explore how the world and human life look once humanism has been finally abandoned.Straw Dogs explores philosophical issues such as the nature of the self, free will, morality, progress and the value of truth. Drawing his inspiration from art, poetry, and the frontiers of science as well as philosophy itself, John Gray presents a post-humanist view of the world and of human life. Straw Dogs is an exhilarating, sometimes disturbing book that leads the reader to question their deepest beliefs.

    Published in early 1968, it both kindled and colored the May 1968 upheavals in France, which captured the attention of the world. Naming and defining the alienating features of everyday life in consumer society: survival rather than living in full, the call to sacrifice, the cultivation of false needs, the dictatorship of the commodity, subjection to social roles, and the replacement of God by the economy, the book argues that the countervailing impulses that exist within deep alienation - creativity, spontaneity, poetry present an authentic alternative to nilhilistic consumerism. This carefully edited new translation marks the first North American publication of this important work and includes a new preface by the author.

    Few write for the non-specialist as well as Will Durant, and this book is a splendid example of his eminently readable scholarship. Durant’s insight and wit never cease to dazzle; The Story of Philosophy is a key book for anyone who wishes to survey the history and development of philosophical ideas in the Western world.
