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.

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....

Nietzsche never recovered from his mental breakdown in 1889 and therefore was unable to further any plans he had for the ‘magnum opus’ he had once intended, bringing together in a coherent whole his mature philosophy. It was left to his close friend Heinrich Köselitz and his sister Elizabeth Förster-Nietzsche to go through the remaining notebooks and unpublished writings, choosing sections of particular interest to produce The Will to Power, giving it the subtitle An Attempted Transvaluation of All Values.

E. M. Cioran confronts the place of today's world in the context of human history—focusing on such major issues of the twentieth century as human progress, fanaticism, and science—in this nihilistic and witty collection of aphoristic essays concerning the nature of civilization in mid-twentieth-century Europe.

The Gay Science (The Joyful Wisdom) is one of Nietzsche's greatest books. His wonderfully fertile mind roams over mankind, his thoughts, his emotions, his behaviour and his weaknesses with remarkable clarity, with insight - but also with humour!In this work are 383 separate paragraphs, some short, some long, but all singular observations - the epitome of his famous aphoristic style. 'Morality is the herd instinct in the individual.'

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.

Sartre's greatest novel and existentialism's key text, now introduced by James Wood, and read by the inimitable Edoardo Ballerini. Nausea is the story of Antoine Roquentin, a French writer who is horrified at his own existence. In impressionistic, diary form, he ruthlessly catalogs his every feeling and sensation.

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'.

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.

In 1913, the Viennese aristocracy is gathering to celebrate the 17th jubilee of the accession of Emperor Franz Josef, even as the Austro-Hungarian Empire is collapsing and the rest of Vienna is showing signs of rebellion. At the centre of this social labyrinth is Ulrich: a veteran, a seducer and a scientist, yet also a man 'without qualities' and therefore a brilliant and detached observer of his changing world.

One of the world's most renowned theoretical physicists, Carlo Rovelli has entranced millions of readers with his singular perspective on the cosmos. In Helgoland, he examines the enduring enigma of quantum theory. The quantum world Rovelli describes is as beautiful as it is unnerving. Helgoland is a treeless island in the North Sea where the 23-year-old Werner Heisenberg made the crucial breakthrough for the creation of quantum mechanics, setting off a century of scientific revolution.

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.

When the narrator of Swann's Way dips a petite madeleine into hot tea, the act transports him to his childhood in the French town of Combray. Out of his Pandora's box of reflections comes a memory of an old family friend, Swann - a man who was long ago undone by romantic desire and cruel reality. In this reverie lie the insights the author seeks about his own life and ageless truths about the ephemeral nature of emotions, places, and, ultimately, love.

Assembled from notes and jottings left unpublished at the time of the author’s death, The Book of Disquiet is a collection of aphoristic prose-poetry musings on dreams, solitude, time and memory. Credited to Pessoa’s alter ego, Bernardo Soares, who chronicles his contemplations in this so-called "factless" autobiography, the work is a journey of one man’s soul and, by extension, of all human souls that allow their minds and hearts to roam far and free.
