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.

This first new translation of Kierkegaard's masterwork in a generation brings an essential work of modern philosophy to vivid life. While the majority of Kierkegaard's work leading up to The Concept of Anxiety dealt with the intersection of faith and knowledge, here the renowned Danish philosopher turns to the perennial question of sin and guilt. First published in 1844, this concise treatise identified - long before Freud - anxiety as a deep-seated human state, one that embodies the endless struggle with our own spiritual identities.

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.  

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.

In On the Genealogy of Morals, subtitled "A Polemic", Nietzsche furthers his pursuit of a clarity that is less tainted by imposed prejudices. He looks at the way attitudes towards 'morality' evolved and the way congenital ideas of morality were heavily colored by the Judaic and Christian traditions.

Ethics is one of the most unique works in Western philosophy, an attempt to handle metaphysics, theology, anthropology, and ontology through the lens of geometric proofs. Spinoza felt that the path to happiness is through reason, in the use of the mind to demystify our existence and liberate us from passions and superstitions.

The Consolation of Philosophy is one of the key works in the rich tradition of Western philosophy, partly because of the circumstances in which it was written. Anicius Manlius Severinus Boethius (c480-c524) was of aristocratic Roman birth and became consul and then master of offices at Ravenna, one of the highest posts under the Ostrogothic Roman ruler Theodoric. But Boethius was unjustly charged with treason in 524, and this led to house arrest, then torture and execution.

Slavoj Žižek's first book is a provocative and original work looking at the question of human agency in a postmodern world. In a thrilling tour de force that made his name, he explores the ideological fantasies of wholeness and exclusion which make up human society. 

The Parallax View is Slavoj Žižek's most substantial theoretical work to appear in many years; Žižek himself describes it as his magnum opus. Parallax can be defined as the apparent displacement of an object, caused by a change in observational position. Žižek is interested in the "parallax gap" separating two points between which no synthesis or mediation is possible, linked by an "impossible short circuit" of levels that can never meet. From this consideration of parallax, Žižek begins a rehabilitation of dialectical materialism.

At the center of The Dark Night of the Soul (La noche oscura del alma) is a poem written by the 16th century Spanish poet and mystic St John of the Cross. Consisting of eight stanzas, each of five lines, the poem outlines the journey in pursuit of divine union, within which the only source of light comes from the soul. This recording in English includes the poem itself and St John's two accompanying treatises (1584-1585), essentially commentaries, which offer line-by-line explanations of the poem. Many modern listeners have found guidance and consolation in this work. 

A story of spiritual awakening, St. Augustine's Confessions is a fascinating look at the life of an eminent Christian thinker. Widely seen as one of the first Western autobiographies ever written, it chronicles the life and religious struggles of Augustine of Hippo, from his days as a self-confessed sinner to his acceptance of Christianity as an older adult.

Faust is one of the pillars of Western literature. This classic drama presents the story of the scholar Faust, tempted into a contract with the Devil in return for a life of sensuality and power. Enjoyment rules, until Faust’s emotions are stirred by a meeting with Gretchen, and the tragic outcome brings Part 1 to an end. Part 2, written much later in Goethe’s life, places his eponymous hero in a variety of unexpected circumstances, causing him to reflect on humanity and its attitudes to life and death.

Schopenhauer was just 30 when his magnum opus, Die Welt als Wille und Vorstellung, a work of considerable learning and innovation of thought, first appeared in 1818.

Much to his chagrin and puzzlement (so convinced was he of its merits), it didn't have an immediate effect on European philosophy, views and culture. It was only decades later that it was recognised as one of the major intellectual landmarks of the 19th century.

Written after the capture of Rome in 410 by Alaric, King of the Visigoths, St Augustine's City of God was intended as a response to pagan critics who blamed Christianity for this brutal defeat. Augustine attacks ancient pagan beliefs and relates the corruption and immorality that led to Rome's downfall, which began before Christ, before reaching his main argument: that the City of Man is perishing and only the Heavenly City of God will endure.

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.
