The Republic is perhaps the single most important, the most studied and the most quoted text of all of Plato's Socratic Dialogues. Through the medium of Socrates, Plato outlines his view and ideas concerning the ideal working of the city-state. Socrates narrates a conversation that took place the previous day with Cephalus, Glaucon, Thrasymachus and others. The dialogue is organised into 10 books and covers a broad range of topics, including the ideal community and the ideal rulers of the community.

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.

Here are the Socratic Dialogues presented as Plato designed them to be - living discussions between friends and protagonists, with the personality of Socrates himself coming alive as he deals with a host of subjects, from justice and inspiration to courage, poetry and the gods. Plato's Socratic Dialogues provide a bedrock for classical Western philosophy. For centuries they have been read, studied and discussed via the flat pages of books, but the ideal medium for them is the spoken word.

The remarkable range of Plato's Dialogues is vividly demonstrated by these three works. It opens with Phaedrus, a highly personal discussion between Socrates (David Rintoul) and the young, love-struck Phaedrus (Gunnar Cauthery). They go for a walk outside the walls of Athens and, under a plane tree by the banks of the Ilissus, talk about love - erotic and 'Platonic' love. Socrates endeavours to steer Phaedrus away from infatuation and show him that real love is based on concern for the beloved.

These five very different Socratic Dialogues date from Plato's later period, when he was revisiting his early thoughts and conclusions and showing a willingness for revision. In Timaeus (mainly a monologue read by David Timson in the title role), Plato considers cosmology in terms of the nature and structure of the universe, the ever-changing physical world and the unchanging eternal world. And he proposes a demiurge as a benevolent creator God.

The Golden Bough, the monumental study of religious rites and practices in ‘primitive’ societies, was one of the earliest influential texts in anthropology. Its author, Sir James Frazer, surveyed the wide range of cultural habits, taboos and beliefs in communities across the world concluding that there was an observable pattern in the way magic developed into religion, though formal expression emerged in different ways.

The Summa Theologica, by Thomas Aquinas, is a fundamental text in Catholic doctrine, a compendium of theology that has been studied and debated since its first publication in the 13th century. Furthermore, it has been widely regarded as one of the classics of Western philosophy, not least because, perhaps for the first time in such a systematic manner, it set out to consider the views of non-Christian figures such as Aristotle, Boethius, Muslim writers including Averroes (Ibn Rushd) and Avicenna (Ibn Sina) and the Sephardic Jewish scholar Maimonides.

First published in 1621, and hardly ever out of print since, it is a huge, varied, idiosyncratic, entertaining and learned survey of the experience of melancholy, seen from just about every possible angle that could be imagined. The Anatomy of Melancholy, presented here with all the original quotations in English, is, at last, available on audiobook in its entirety.

Summa Theologica consists of three main parts. The second part is divided two, and this recording presents Prima Secundae - Part I of Part II. Taken in its entirety, Summa Theologica forms an essential contribution to the canon of Catholic doctrine and was written in the last decade of his life by Thomas Aquinas (1225-1274), an Italian-born Dominican friar. Although he died before completing it, the body of thought it contains is a continuing influence to the education and guidance of students of theology in the main Christian traditions.

Secunda Secundae is the longest part in this immense undertaking by Thomas Aquinas (1225-1274). His purpose was nothing less than to survey the theological teachings of the Catholic Church, while absorbing, controversially for his time, many other strands of learning and philosophy, varying from ancient Greek (particularly Aristotle) to Muslim writers (Averroes and Avicenna) and the Sephardic Jewish philosopher Moses Maimonides.

Summa Theologica Part III (Tertia Pars) is Volume 4 in Ukemi Audiobooks’ complete recording of Thomas Aquinas’s momentous work on Christian theology and philosophy. The presentation of the discussions in Part III follow the pattern we have become so familiar with from earlier Parts with the statement of the question, then a series of objections, further considerations and finally Aquinas’s replies to each of the objections.

Aristotle’s Organon comprises six key essays on logic, initially collected by Theophrastus, his successor as head of the Peripatetic school, and given its final form by Andronicus some three centuries later. The six essays are: Categories, On Interpretation, Prior Analytics, Posterior Analytics, Topics and On Sophistical Refutations. One of the principal topics of Aristotle’s focus is syllogism, in which two premises (one major, one minor) lead to a conclusion. This features in Prior Analytics and On Interpretation.

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.

Man and His Symbols owes its existence to one of Jung's own dreams. The great psychologist dreamed that his work was understood by a wide public, rather than just by psychiatrists, and therefore he agreed to write and edit this fascinating book. Here, Jung examines the full world of the unconscious, whose language he believed to be the symbols constantly revealed in dreams.

Immanuel Kant’s Critique of Pure Reason can lay claim to being the most important single work of modern philosophy, a work whose methodology, if not necessarily always its conclusions, has had a profound influence on almost all subsequent philosophical discourse. In this work Kant addresses, in a groundbreaking elucidation of the nature of reason, the age-old question of philosophy: “How do we know what we know?” and the limits of what it is that we can know with certainty.
