"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.

    It furnishes us with a key to his main work, The Critique of Pure Reason; in fact, it is an extract containing all the salient ideas of Kant's system. It approaches the subject in the simplest and most direct way, and is therefore best adapted as an introduction into his philosophy.

    Nietzsche rewrites the former as a history of cruelty, exposing the central values of the Judaeo-Christian and liberal traditions - compassion, equality, justice - as the product of a brutal process of conditioning designed to domesticate the animal vitality of earlier cultures. The result is a book which raises profoundly disquieting issues about the violence of both ethics and interpretation. Nietzsche questions moral certainties by showing that religion and science have no claim to absolute truth, before turning on his own arguments in order to call their very presuppositions into question. The Genealogy is the most sustained of Nietzsche's later works and offers one of the fullest expressions of his characteristic concerns. This edition places his ideas within the cultural context of his own time and stresses the relevance of his work for a contemporary audience.

    The speech is significant both because its topic remains timely and because its arguments illustrate the applicability of the principle of utility to questions of large-scale social policy.

    Descartes's Meditations on First Philosophy, the fundamental and originating work of the modern era in Western philosophy, is presented here in Donald Cress's completely revised edition of his well-established translation, bringing this version even closer to Descartes's original, while maintaining its clear and accessible style.

    In seventy-six chapters he traces philosophy from the rise of Greek civilization to the emergence of logical analysis in the twentieth century. Among the philosophers considered are: Pythagoras, Heraclitus, Parmenides, Empedocles, Anaxagoras, the Atomists, Protagoras, Socrates, Plato, Aristotle, the Cynics, the Sceptics, the Epicureans, the Stoics, Plotinus, Ambrose, Jerome, Augustine, Benedict, Gregory the Great, John the Scot, Aquinas, Duns Scotus, William of Occam, Machiavelli, Erasmus, More, Bacon, Hobbes, Descartes, Spinoza, Leibniz, Locke, Berkeley, Hume, Rousseau, Kant, Hegel, Schopenhauer, Nietzsche, the Utilitarians, Marx, Bergson, James, Dewey, and lastly the philosophers with whom Lord Russell himself is most closely associated -- Cantor, Frege, and Whitehead, co-author with Russell of the monumental Principia Mathematica.

    The Penseés is a collection of philosohical fragments, notes and essays in which Pascal explores the contradictions of human nature in pscyhological, social, metaphysical and - above all - theological terms. Mankind emerges from Pascal's analysis as a wretched and desolate creature within an impersonal universe, but who can be transformed through faith in God's grace.

    Present here is a remarkable combination of the insight of the poet and the contemplation of the philosopher.In The Sickness unto Death, Kierkegaard moves beyond anxiety on the mental-emotional level to the spiritual level, where — in contact with the eternal — anxiety becomes despair. Both anxiety and despair reflect the misrelation that arises in the self when the elements of the synthesis — the infinite and the finite — do not come into proper relation to each other. Despair is a deeper expression for anxiety and is a mark of the eternal, which is intended to penetrate temporal existence.

    It begins with a Preface, created after the rest of the manuscript was completed, that explains the core of his method and what sets it apart from any preceding philosophy. The Introduction, written before the rest of the work, summarizes and completes Kant's ideas on skepticism by rendering it moot and encouraging idealism and self-realization. The body of the work is divided into six sections of varying length, entitled "Consciousness," "Self-Consciousness," "Reason," "Spirit," "Religion," and "Absolute Knowledge." A myriad of topics are discussed, and explained in such a harmoniously complex way that the method has been termed Hegelian dialectic. Ultimately, the work as a whole is a remarkable study of the mind's growth from its direct awareness to scientific philosophy, proving to be a difficult yet highly influential and enduring work.

    But his penetrating work of political philosophy - now fully revised and with a new introduction for this edition - opened up questions about the nature of statecraft and society that influenced governments across the world.

    Similarly neither can one day, or a brief space of time, make a man blessed and happy’In the Nicomachean Ethics, Aristotle sets out to examine the nature of happiness. He argues that happiness consists in ‘activity of the soul in accordance with virtue’, for example with moral virtues, such as courage, generosity and justice, and intellectual virtues, such as knowledge, wisdom and insight. The Ethics also discusses the nature of practical reasoning, the value and the objects of pleasure, the different forms of friendship, and the relationship between individual virtue, society and the State. Aristotle’s work has had a profound and lasting influence on all subsequent Western thought about ethical matters.J. A. K. Thomson’s translation has been revised by Hugh Tredennick, and is accompanied by a new introduction by Jonathan Barnes. This edition also includes an updated list for further reading and a new chronology of Aristotle’s life and works.Previously published as Ethics

    In his introductory essay, John Cooper explains the presentation of these works, discusses questions concerning the chronology of their composition, comments on the dialogue form in which Plato wrote, and offers guidance on approaching the reading and study of Plato's works.Also included are concise introductions by Cooper and Hutchinson to each translation, meticulous annotation designed to serve both scholar and general reader, and a comprehensive index. This handsome volume offers fine paper and a high-quality Smyth-sewn cloth binding in a sturdy, elegant edition.

    Following a logical step-by-step format, it defines in turn the nature of God, the mind, the emotions, human bondage to the emotions, and the power of understanding - moving from a consideration of the eternal, to speculate upon humanity's place in the natural order, the nature of freedom and the path to attainable happiness. A powerful work of elegant simplicity, the Ethics is a brilliantly insightful consideration of the possibility of redemption through intense thought and philosophical reflection. The Ethics is presented in the standard translation of the work by Edwin Curley. This edition also includes an introduction by Stuart Hampshire, outlining Spinoza's philosophy and placing it in context.

    The Age of Reason represents the results of years of study and reflection by Thomas Paine on the place of religion in society.Paine wrote: "Of all the tyrannies that affect mankind, tyranny in religion is the worst; every other species of tyranny is limited to the world we live in; but this attempts to stride beyond the grave, and seeks to pursue us into eternity."The cool rationale of Paine's The Age of Reason influenced religious thinking throughout the world; and its pervasieve influence continues to the present day.
