The author’s final work, presented in a one-volume edition, is a rich, challenging analysis of man’s mental activity, considered in terms of thinking, willing, and judging.

    A lively and still one of the best introductions to philosophy, this book pays off both a closer reading for students and specialists, and a casual reading for the general public.

    He saw in it the rise and climax of values so dear to him that their subsequent drop into catastrophe (in the person of Socrates - Plato) was clearly foreshadowed as though these were events taking place in the theater.And so in this work, unpublished in his own day but written at the same time that his The Birth of Tragedy had so outraged the German professorate as to imperil his own academic career, his most deeply felt task was one of education. He wanted to present the culture of the Greeks as a paradigm to his young German contemporaries who might thus be persuaded to work toward a state of culture of their own; a state where Nietzsche found sorely missing.

    It redirected philosophical attention to neglected questions of natural and metaphysical necessity and to the connections between these and theories of reference, in particular of naming, and of identity. From a critique of the dominant tendency to assimilate names to descriptions and more generally to treat their reference as a function of their Fregean sense, surprisingly deep and widespread consequences may be drawn. The largely discredited distinction between accidental and essential properties, both of individual things (including people) and of kinds of things, is revived. So is a consequent view of science as what seeks out the essences of natural kinds. Traditional objections to such views are dealt with by sharpening distinctions between epistemic and metaphysical necessity; in particular by the startling admission of necessary a posteriori truths. From these, in particular from identity statements using rigid designators whether of things or of kinds, further remarkable consequences are drawn for the natures of things, of people, and of kinds; strong objections follow, for example to identity versions of materialism as a theory of the mind.This seminal work, to which today's thriving essentialist metaphysics largely owes its impetus, is here published with a substantial new Preface by the author.

    Written in short, carefully numbered paragraphs of extreme brilliance, it captured the imagination of a generation of philosophers. For Wittgenstein, logic was something we use to conquer a reality which is in itself both elusive and unobtainable. He famously summarized the book in the following words: 'What can be said at all can be said clearly; and what we cannot talk about we must pass over in silence.' David Pears and Brian McGuinness received the highest praise for their meticulous translation. The work is prefaced by Bertrand Russell's original introduction to the first English edition.

    A. A. Long, a leading scholar of later ancient philosophy, gives the definitive presentation of the thought of Epictetus for a broad readership. Long's fresh and vivid translations of a selection of the best of Epictetus' discourses show that his ideas are as valuable and striking today as they were almost two thousand years ago. This is a book for anyone interested in what we can learn from ancient philosophy about how to live our lives.

    His biting wit and eccentric behavior were legendary, and it was by means of his renowned aphorisms that his moral teachings were transmitted. He scorned the conventions of civilized life, and his ascetic lifestyle and caustic opinions informed the Cynic philosophy and later influenced Stoicism. This unique edition also covers his immediate successors, such as Crates, his wife Hipparchia, and the witty moral preacher Bion. The contrasting teachings of the Cyrenaic school, founded by Aristippos, a pleasure-loving friend of Socrates, complete the volume, together with a selection of apocryphal letters.About the Series: For over 100 years Oxford World's Classics has made available the broadest spectrum of literature from around the globe.

    They chart the course of "true" socialism based on G. W.F. Hegel's dialectic, while criticizing the ideas of Bruno Bauer, Max Stirner and Ludwig Feuerbach. Marx expanded his criticism of the latter in his now famous Theses on Feuerbach, found after Marx's death and published by Engels in 1888. Introduction to the Critique of Political Economy, also found among the posthumous papers of Marx, is a fragment of an introduction to his main works. Combining these three works, this volume is essential for an understanding of Marxism.

    It presents a profound and challenging investigation into the nature of human reason, its knowledge and its illusions. Reason, Kant argues, is the seat of certain concepts that precede experience and make it possible, but we are not therefore entitled to draw conclusions about the natural world from these concepts. The Critique brings together the two opposing schools of philosophy: rationalism, which grounds all our knowledge in reason, and empiricism, which traces all our knowledge to experience. Kant's transcendental idealism indicates a third way that goes far beyond these alternatives.

    The general approach of this book to logic remains the same as in earlier editions. Following Aristotle, we regard logic from two different points of view: on the one hand, logic is an instrument or organon for appraising the correctness of reasoning; on the other hand, the principles and methods of logic used as organon are interesting and important topics to be themselves systematically investigated.

    It remains the one of the most widely read books about science to come out of the twentieth century.(Note: the book was first published in 1934, in German, with the title Logik der Forschung. It was "reformulated" into English in 1959. See Wikipedia for details.)

    Heath's translation of the thirteen books of Euclid's Elements. In keeping with Green Lion's design commitment, diagrams have been placed on every spread for convenient reference while working through the proofs; running heads on every page indicate both Euclid's book number and proposition numbers for that page; and adequate space for notes is allowed between propositions and around diagrams. The all-new index has built into it a glossary of Euclid's Greek terms.Heath's translation has stood the test of time, and, as one done by a renowned scholar of ancient mathematics, it can be relied upon not to have inadvertantly introduced modern concepts or nomenclature. We have excised the voluminous historical and scholarly commentary that swells the Dover edition to three volumes and impedes classroom use of the original text. The single volume is not only more convenient, but less expensive as well.

    In his political speeches especially and in his correspondence we see the excitement, tension and intrigue of politics and the part he played in the turmoil of the time. Of about 106 speeches, delivered before the Roman people or the Senate if they were political, before jurors if judicial, 58 survive (a few of them incompletely). In the fourteenth century Petrarch and other Italian humanists discovered manuscripts containing more than 900 letters of which more than 800 were written by Cicero and nearly 100 by others to him. These afford a revelation of the man all the more striking because most were not written for publication. Six rhetorical works survive and another in fragments. Philosophical works include seven extant major compositions and a number of others; and some lost. There is also poetry, some original, some as translations from the Greek. The Loeb Classical Library edition of Cicero is in twenty-nine volumes.

    The subjects treated include Abraham, Angel and Anthropophages; Baptism, Beauty and Beasts; Fables, Fraud and Fanaticism; Metempsychosis, Miracles and Moses; all of them exposed to Voltaire's lucid scrutiny, his elegant irony and his passionate love of reason and justice.
