Karl Popper's THE POVERTY OF HISTORICISM is one of the most important books on the social sciences to have appeared since the Second World War. It is also the work of one of the most original thinkers of the twentieth century, and a devastating criticism of the idea that there are laws of development in history and that human beings are able to discover them. Popper dedicated the book to all those who fell victim to the fascist and communist belief in Inexorable Laws of Historical Destiny

Conjectures and Refutations is one of Karl Popper’s most wide-ranging and popular works, notable not only for its acute insights into the way scientific knowledge grows, but also for applying those insights to politics and to history. It provides one of the clearest and most accessible statements of the fundamental idea that guided his work: not only our knowledge but our aims and our standards grow through an unending process of trial and error.

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.

All Life is Problem Solving is a stimulating and provocative selection of Popper's writings on his main preoccupations during the last twenty-five years of his life. This collection illuminates Popper's process of working out key formulations in his theory of science, and indicates his view of the state of the world at the end of the Cold War and after the collapse of communism.

This recording contains four important and related works by Heidegger: 'What Is Philosophy', 'What Is Metaphysics', 'On the Essence of Truth' and 'The Question of Being'.

At the age of eight, Karl Popper was puzzling over the idea of infinity and by fifteen was beginning to take a keen interest in his father's well-stocked library of books. Unended Quest recounts these moments and many others in the life of one of the most influential thinkers of the twentieth century, providing an indispensable account of the ideas that influenced him most. As an introduction to Popper's philosophy, Unended Quest also shines. Popper lucidly explains the central ideas in his work, making this book ideal for anyone coming to Popper's life and work for the first time.

Towards the end of his life, Seneca the Younger (c4 BCE-65 CE) began a correspondence with a friend in Sicily, later collected under the title The Moral Epistles. In these 124 letters, Seneca expresses, in a wise, steady and calm manner, the philosophy by which he lived - derived essentially from the Stoics. The letters deal with a variety of specific topics - often eminently practical - such as 'On Saving Time', 'On the Terrors of Death', 'On True and False Friendships', 'On Brawn and Brains' and 'On Old Age and Death'.

Epicurus of Samos (341-270 BCE) was the founder of the philosophical system to which he gave his name: Epicureanism. It is a label that is often misused and misunderstood today, with ‘a life of pleasure’ as the key aim misinterpreted as a life of indulgence. In fact, the philosophy of Epicurus demonstrated also by his life, was anything but! He established a school in Athens called The Garden, underpinned by his system of ethics.

Here, in this second collection of Socratic Dialogues from Plato's Early Period, read by David Rintoul as Socrates with a full cast, are contrasting six works. Often, as with Gorgias, which opens the recording, Socrates combats the popular subjects of sophistry and rhetoric, in direct conversation with Gorgias (a leading sophist teacher), and with one of his pupils, Callicles.

'On Anger' is one of Seneca's most important essays. At some length he investigates the nature of anger: how and why it emerges, the effect it has on the individual and those to whom it is directed, and how to manage it and prevent it even from arising. For, Seneca considers, anger simply serves no purpose - it does not bring courage in war, prevent others misbehaving or punish miscreants. In short it has a negative effect on all. In 'On Leisure' he takes a short look at what is really meant by the term.

The rivalry between two of the dominant city states of Ancient Greece, Athens and Sparta, erupted into a war lasting nearly 30 years and was to have a dramatic effect on the balance of power in the area. Between 431 and 404 BCE, the two cities battled it out on land and sea, aided by their alliances with neighbouring states: Athens’ Delian League vigorously opposed Sparta’s Peloponnesian League in a conflict which effectively involved the whole region.

First published in French in 1907, Henri Bergson's L'évolution créatrice is a scintillating and radical work by one of the great French philosophers of the nineteenth and twentieth centuries. This outstanding new translation, the first for over a hundred years, brings one of Bergson's most important and ambitious works to a new generation.

Kant's Prolegomena, although a small book, is without doubt the most important of his writings, writes the translator, Paul Carus. Prolegomena means, literally, prefatory or introductory remarks, and 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.

The Laws is the longest of Plato’s Dialogues and actually doesn’t feature Socrates at all - the principal figure taking the lead is the ‘Athenian Stranger’ who engages two older men in the discussion, Cleinias (from Crete) and Megillus (from Sparta). The Dialogue is set in Crete, and the three men embark on a pilgrimage from Knossus to the cave of Dicte, where, legend reports, Zeus was born.

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.’

In a letter of 1932, Karl Popper described Die beiden Grundprobleme der Erkenntnistheorie–The Two Fundamental Problems of the Theory of Knowledge–as ‘…a child of crises, above all of …the crisis of physics.' The two fundamental problems of knowledge that lie at the center of the book are the problem of induction, that although we are able to observe only a limited number of particular events, science nevertheless advances unrestricted universal statements; and the problem of demarcation, which asks for a separating line between empirical science and non-science.

Paul Feyerabend’s globally acclaimed work, which sparked and continues to stimulate fierce debate, examines the deficiencies of many widespread ideas about scientific progress and the nature of knowledge. Feyerabend argues that scientific advances can only be understood in a historical context. He looks at the way the philosophy of science has consistently overemphasized practice over method, and considers the possibility that anarchism could replace rationalism in the theory of knowledge.

This collection illuminates Popper's process of working out key formulations in his theory of science, and indicates his view of the state of the world at the end of the Cold War and after the collapse of communism.

An immediate sensation when it was first published in two volumes in 1945, Popper's monumental achievement has attained legendary status on both the Left and Right and is credited with inspiring anticommunist dissidents during the Cold War. Arguing that the spirit of free, critical inquiry that governs scientific investigation should also apply to politics, Popper traces the roots of an opposite, authoritarian tendency to a tradition represented by Plato, Marx, and Hegel.

Timothy Williamson tackles some of the key questions surrounding philosophy in new and provocative ways, showing how philosophy begins in common sense curiosity, and develops through our capacity to dispute rationally with each other. Discussing philosophy's ability to clarify our thoughts, he explains why such clarification depends on the development of philosophical theories, and how those theories can be tested by imaginative thought experiments, and compared against each other by standards similar to those used in the natural and social sciences.

This Leibniz collection contains some of the philosopher’s most important works and ideas, spans three decades and illuminates the fascinating intellectual journey undertaken by him in his quest for truth. A prodigious polymath, Leibniz was a mathematician, philosopher, physicist and statesman and engaged with a sweeping range of ideas and disciplines, striving throughout his life to be at the cutting edge of scientific thinking. These Principal Essays are arranged in chronological order.

In 1929, Martin Heidegger (1889-1976) published his remarkable book Kant and the Problem of Metaphysics. The Kantbuch, as Heidegger often called it, is regarded by many as a vital supplement to the unfinished second part of Heidegger’s most influential work, Being and Time, which was published two years earlier in 1927.

It was with Human, All Too Human, first published in 1878, that Nietzsche developed the aphoristic style that so suited his challenging views and uncompromising style. The text is divided into three main sections: 'Of the First and Last Things', 'History of the Moral Feelings' and 'The Religious Life'.

Critique of Judgement was published in 1790 and is divided into two parts, the Critique of Aesthetic Judgement and the Critique of Teleological Judgement. Our ‘judgements of taste’, as Kant describes our aesthetic judgements, have both a personal and a universal function: personal, because we have a subjective aesthetic response to the ‘agreeable’, the ‘beautiful’, the ‘sublime’ and the ‘good’; but also there is a ‘universal’ aspect because our aesthetic response has a ’disinterested’ element. This brings under Kant’s spotlight, for example, the concept of beauty and the perception of beauty.

Kant's Prolegomena, although a small book, is without doubt the most important of his writings, writes the translator, Paul Carus.

John Locke and his works - particularly An Essay Concerning Human Understanding - are regularly and rightly presented as foundations for the Age of Enlightenment. His primary epistemological message - that the mind at birth is a blank sheet waiting to be filled by the experiences of the senses - complemented his primary political message: that human beings are free and equal and have the right to envision, create and direct the governments that rule them and the societies within which they live.
