Philosophical Investigations was published in 1953, two years after the death of its author. In the preface written in Cambridge in 1945 where he was professor of philosophy he states: ‘Four years ago I had occasion to re-read my first book (the Tractatus Logico-Philosophicus) and to explain its ideas to someone. It suddenly seemed to me that I should publish those old thoughts and the new ones together: that the latter could be seen in the right light only by contrast with and against the background of my old way of thinking.’

Considered to be one of the most important philosophical works of all time, the History of Western Philosophy is a dazzlingly unique exploration of the ideologies of significant philosophers throughout the ages - from Plato and Aristotle through to Spinoza, Kant and the 20th century. Written by a man who changed the history of philosophy himself, this is an account that has never been rivaled since its first publication over 60 years ago.

Elements of The Philosophy of Right, a key work in the output of Georg Wilhelm Hegel (1770-1831), appeared in 1820 - and was arguably his last major publication. His intention was to state his views on the philosophy of law, political and social theory and ethics. Appearing as it did in a crucial time for the Prussian state - still affected by the Napoleonic wars and their aftermath - it was viewed differently by those on both the left and the right of the political spectrum.

Philosophy of Mind is the third and final part of the Encyclopaedia of the Philosophical Sciences, the collection in which Hegel (1730-1831) offered an overview of his life’s work. Though originally written in 1817, he revised it in 1830, thus providing a finished form the year before his death. Hegel used the three parts of the Encyclopaedia - Science of Logic, Philosophy of Nature and Philosophy of Mind - as a basis for lectures at the Universities of Heidelberg which he joined in 1816, and in Berlin in 1820.

From the perspective of an unbeliever, Fear and Trembling explores the paradox of faith, the nature of Christianity, and the complexity of human emotion. Kierkegaard examines the biblical story of Abraham, who was instructed to sacrifice his son Isaac, and forces us to consider Abraham's state of mind. What drove Abraham, and what made him carry out such an absurd and extreme request from God? Kierkegaard argues that Abraham's agreement to sacrifice Isaac, and his suspension of reason, elevated him to the highest level of faith.

Perhaps one of the most revolutionary works of philosophy ever presented, The Phenomenology of Spirit is Hegel's 1807 work that is in numerous ways extraordinary. 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.

Being and Time was published in 1927 during the Weimar period in Germany, a time of political, social and economic turmoil. Heidegger himself did not escape the pressures and his nationalism, and undeniable anti-Semitism in the following decades cast a shadow over the man, but not the work. Being and Time is not coloured by expressions of his later views (unlike other writings) and remains an outstanding document.

From the best-selling authors of The Daily Stoic comes an inspiring guide to the lives of the Stoics, and what the ancients can teach us about happiness, success, resilience, and virtue. In Lives of the Stoics, Holiday and Hanselman present the fascinating lives of the men and women who strove to live by the timeless Stoic virtues of Courage. Justice. Temperance. Wisdom. Organized in digestible, mini-biographies of all the well-known - and not so well-known - Stoics, this book vividly brings home what Stoicism was like for the people who loved it and lived it.

In a career spanning 60 years, Sir Karl Popper has made some of the most important contributions to the 20th century discussion of science and rationality. The Myth of the Framework is a collection of some of Popper's most important material on this subject.

The Origins and History of Consciousness draws on a full range of world mythology to show how individual consciousness undergoes the same archetypal stages of development as human consciousness as a whole. Erich Neumann was one of C. G. Jung's most creative students and a renowned practitioner of analytical psychology in his own right. In this influential book, Neumann shows how the stages begin and end with the symbol of the Uroboros, the tail-eating serpent.

In this classic work, Huntington challenges old assumptions and ideas on the role of the military in society. Stressing the value of the military outlook for American national policy, Huntington has performed the distinctive task of developing a general theory of civil-military relations and subjecting it to rigorous historical analysis.

Modern Man in Search of a Soul is the classic introduction to the thought of Carl Jung. Along with Freud and Adler, Jung was one of the chief founders of modern psychiatry. In this book, Jung examines some of the most contested and crucial areas in the field of analytical psychology: dream analysis, the primitive unconscious, and the relationship between psychology and religion.

In this work Cioran writes about Western civilizations, the writer, the novel, about mystics, apostles, philosophers. For those to whom the very word philosophy brings visions of arduous reading, be assured: Cioran is crystal-clear, his style quotable and aphoristic.

This metaphysical self-help classic instills happiness within and urges individuals to pursue a content life without sin, boredom, or contempt. Written decades ago with post-war depression in mind, this text has transcended time and continues to give applicable advice for modern-day individuals.

Ludwig Wittgenstein (1889-1951) was an extraordinarily original thinker, whose influence on 20th-century thinking far outside the bounds of philosophy alone. In this engaging Introduction, A. C. Grayling makes Wittgenstein's thought accessible to the general listener by explaining the nature and impact of Wittgenstein's views. He describes both his early and later philosophy, the differences and connections between them, and gives a fresh assessment of Wittgenstein's continuing influence on contemporary thought.

The Tractatus Logico-Philosophicus (Logical Philosophical Treatise or Treatise on Logic and Philosophy) is the only full-length philosophical book by the Austrian philosopher Ludwig Wittgenstein that was published during his lifetime. The goal of the work is to identify the relationship between language and reality and to define the limits of science. He famously summarized the book in the following way: "What can be said at all can be said clearly; and what we cannot talk about we must pass over in silence."

The Problems of Philosophy discusses Bertrand Russell's views on philosophy and the problems that arise in the field. Russell's views focus on knowledge rather than the metaphysical realm of philosophy. The Problems with Philosophy revolves around the central question that Russell asks in his opening line of Chapter 1 - Is there any knowledge in the world which is so certain that no reasonable man could doubt it?

One of the most influential philosophers and theologians in the history of Western thought, St Thomas Aquinas established the foundations for much of modern philosophy of religion, and is famous for his arguments for the existence of God. In this cogent and multifaceted introduction to the great saint's work, Edward Feser argues that you cannot fully understand Aquinas' philosophy without his theology, and vice-versa. He covers Aquinas' thoughts on the soul, natural law, metaphysics, and more.

There is a cause, or a reason, behind everything that happens. This is the fundamental view behind the classical proposition the Principle of Sufficient Reason, which, in 1813, Schopenhauer chose as his subject for further examination in his doctoral dissertation On the Fourfold Root of the Principle of Sufficient Reason....

Despite the recent ferocious public debate about belief, the concept most central to the discussion "God" frequently remains vaguely and obscurely described. Are those engaged in these arguments even talking about the same thing? In a wide-ranging response to this confusion, esteemed scholar David Bentley Hart pursues a clarification of how the word "God” functions in the world’s great theistic faiths.

What does it mean to be truthful? What role does truth play in our lives? What do we lose if we reject truthfulness? No philosopher is better suited to answer these questions than Bernard Williams. Writing with his characteristic combinationof passion and elegant simplicity, he explores the value of truth and finds it to be both less and more than we might imagine.

Logic is synonymous with reason, judgment, sense, wisdom, and sanity. Being logical is the ability to create concise and reasoned arguments - arguments that build from given premises, using evidence, to a genuine conclusion. But mastering logical thinking also requires studying and understanding illogical thinking, both to sharpen one's own skills and to protect against incoherent or deliberately misleading reasoning. Elegant, pithy, and precise, Being Logical breaks logic down to its essentials through clear analysis, accessible examples, and focused insights.

This audiobook is a long-awaited major statement by a pre-eminent analytic philosopher, Alvin Plantinga, on one of our biggest debates - the compatibility of science and religion. The last twenty years has seen a cottage industry of books on this divide, but with little consensus emerging. Plantinga, as a top philosopher but also a proponent of the rationality of religious belief, has a unique contribution to make. His theme in this short book is that the conflict between science and theistic religion is actually superficial, and that at a deeper level they are in concord.

The modern materialist approach to life has conspicuously failed to explain such central mind-related features of our world as consciousness, intentionality, meaning, and value. This failure to account for something so integral to nature as mind, argues philosopher Thomas Nagel, is a major problem, threatening to unravel the entire naturalistic world picture, extending to biology, evolutionary theory, and cosmology. Since minds are features of biological systems that have developed through evolution, the standard materialist version of evolutionary biology is fundamentally incomplete.

Epistemology is the philosophical study of knowledge. Without knowledge, scientific enquiry is meaningless and we can’t analyse the world around us. But what exactly is knowledge and how do we obtain it? Should we trust our senses? When is belief knowledge? Presuming no prior experience, Robert Martin covers everything in the topic from scepticism and induction to Kant’s transcendentalism. Clear and readable, this audiobook is essential for philosophy students and a much needed introduction for the general reader.

The story of philosophy is an epic tale, spanning civilizations and continents. It explores some of the most creative minds in history. But not since the long-popular classic by Bertrand Russell, A History of Western Philosophy, published in 1945, has there been a comprehensive and entertaining single-volume history of this great, intellectual, world-shaping journey.

In There Is a God, one of the world's preeminent atheists discloses how his commitment to "follow the argument wherever it leads" led him to a belief in God as Creator. This is a compelling and refreshingly open-minded argument that will forever change the atheism debate.

Written in 1917, The Law and the Word is a hard-to-find work by Judge Thomas Troward, a pioneer in mental science. Troward's writings and lectures greatly influenced Ernest Holmes, the founder of Religious Science and writer of The Science of Mind.

This book was one of the first to combine thought energy, scientific reasoning and testing, and creative power, and to see the interconnection of the three.

Considered by many to be Hannah Arendt's greatest work, published as she neared the end of her life, The Life of the Mind investigates thought itself, as it exists in contemplative life. In a shift from her previous writings, most of which focus on the world outside the mind, this work was planned as three volumes that would explore the activities of the mind considered by Arendt to be fundamental. What emerged is a rich, challenging analysis of human mental activity, considered in terms of thinking, willing, and judging.

This engaging and accessible book invites the listener to explore the questions and arguments of philosophy through the work of 100 of the greatest thinkers within the Western intellectual tradition - covering philosophical, scientific, political, and religious thought over a period of 2500 years.
