Published first in 1912, Psychology of the Unconscious was one of the most important stepping stones in the development of Jung’s thought and practice. It has a long subtitle: A Study of the Transformations and Symbolisms of the Libido. A Contribution to the History of the Evolution of Thought. This expressed the underlying impetus - a break from the view of the libido and its functions as taught by Sigmund Freud, which Jung had earlier adopted. It was from this point that the two approaches, which came to be known as the Swiss and Viennese schools, emerged.

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.

This collection of 11 wide-ranging lectures which appeared originally in 1933, was based on lectures previously given when Jung was in the process of absorbing a considerable period of study of Eastern religions, Gnosticism and other religious sources. It was a time, according to the translator Cary F. Baynes, ‘when the Western world stands on the verge of a spiritual rebirth...after a long period of outward expansion, we are beginning to look inside ourselves once more.’

The Red Book, published to wide acclaim in 2009, contains the nucleus of C. G. Jung's later works. It was here that he developed his principal theories of the archetypes, the collective unconscious, and the process of individuation that would transform psychotherapy from treatment of the sick into a means for the higher development of the personality.

Collected Papers on Analytical Psychology comprises a selection of key writings and lectures by Carl Gustav Jung produced between 1902 and 1916, which are presented in chronological order. As such they provide a fascinating exposition of the nature and essence of the psychological content of psychoses and neuroses, as explored and discovered by Dr Jung in the early years of his long and distinguished career.

The Interpretation of Dreams by Sigmund Freud is one of the most significant books of the 20th century. Though dreams and their role in human consciousness have been a continuing thread in religion and art and life down the centuries, Freud's look at the subject through the prism of his emerging practice and study of psychoanalysis provided a startlingly new and challenging perspective.

Jung's discovery of the 'collective unconscious', a psychic inheritance common to all humankind, transformed the understanding of the self and the way we interpret the world. In On the Nature of the Psyche Jung describes this remarkable theory in his own words, and presents a masterly overview of his theories of the unconscious, and its relation to the conscious mind. Also contained in this collection is On Psychic Energy, where Jung defends his interpretation of the libido, a key factor in the breakdown of his relations with Freud. 

As the 20th century drew to a close, the Austrian psychologist Alfred Adler (1870-1937) was perhaps the least known of the prominent figures of his time - in particular Sigmund Freud and Carl Gustav Jung - and yet he continues to be a figure of influence in the 21st century. His school of ‘individual psychology’ involved a holistic approach to the study of the individual, with a key focus on the way each person viewed the world, especially regarding their concerns of inferiority.

The Psychopathology of Everyday Life, which appeared first in 1901 and was then expanded in a series of subsequent editions, has proved to be one of Freud's most popular works, and one of his most influential during his lifetime. It was here that he proposed that many slips and errors of memory common to the average man in everyday life actually signals unconscious issues that beset the individual, and, if examined, can be extremely revealing.

For a world that over the past century has witnessed horrors the like of which could not have been imagined by earlier generations, Job’s cries of despair and incomprehension are all too recognisable. The visionary psychotherapist Carl Gustav Jung understood this and responded with this remarkable book, in which he set himself face to face with 'the unvarnished spectacle of divine savagery and ruthlessness'.

Carl Gustav Jung was the 20th century's greatest articulator of the primacy of mind in nature, a view whose origins vanish behind the mists of time. The present book scrutinizes Jung's work to distil and reveal that extraordinary, hidden metaphysical treasure: For Jung, mind and world are one and the same entity; reality is fundamentally experiential, not material; the psyche builds and maintains its body, not the other way around; and the ultimate meaning of our sacrificial lives is to serve God by providing a reflecting mirror to God's own instinctive mentation.

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.

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.

The Divine Comedy describes Dante's descent into Hell with Virgil as a guide, his ascent of Mount Purgatory and his encounter with his dead love Beatrice, and finally, his arrival in Heaven. Examining questions of faith, desire and enlightenment, the poem is a brilliantly nuanced and moving allegory of human redemption. This major translation is published here for the first time in a single volume.

Alfred Adler was an Austrian physician, psychotherapist, and one of the founding fathers of modern psychology. In Understanding Human Nature, (1928), Adler sets out to acquaint the general public with the basics of Individual Psychology, which holds that the driving force of human behavior is the individual’s striving for power, partly to compensate for feelings of inferiority. The purpose of the book is to identify mistaken behaviors and show how they undermine healthy relationships, in order to gently guide the individual towards adjustment.
