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.

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'.

In the 21st century, Carl Gustav Jung (1875-1961) remains one of the key figures in the field of analytical psychology - and Psychological Types, or The Psychology of Individuation, published in 1921, is one of his most influential works. It was written during the decade after the publication of Psychology of the Unconscious (1912), which effectively ended his friendship and collaboration with Sigmund Freud.

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.

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.

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. 

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.

Continuing where Thus Spoke Zarathustra left off, Nietzsche's controversial work Beyond Good and Evil is one of the most influential philosophical texts of the 19th century and one of the most controversial works of ideology ever written. Attacking the notion of morality as nothing more than institutionalised weakness, Nietzsche criticises past philosophers for their unquestioning acceptance of moral precepts. Nietzsche tried to formulate what he called "the philosophy of the future".

In this best-selling book, one of America's most distinguished psychologists crystallises the great progress that has been made in the development of the techniques and basic philosophy of counselling. Carl Rogers gives a clear exposition of procedures by which individuals who are being counselled may be assisted in achieving for themselves new and more effective personality adjustments. Contemporary psychology derives largely from the experimental laboratory or from Freudian theory. It is preoccupied with minute aspects of animal and human behaviour or with psychopathology. 

Thus Spoke Zarathustra is one of the most extraordinary - and important - texts in Western philosophy. It was written by Friedrich Nietzsche between 1883 and 1885. He cast it in the form of a novel in the hope that his urgent message of the 'death of God' and the rise of the superman (Ubermensch) would have greater emotional as well as intellectual impact.

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.

It is said that the practice of dream yoga deepens our awareness during all our experience: the dreams of the night; the dream-like experience of the day; and the bardo experiences after death. Indeed, the practice of dream yoga is a powerful tool of awakening, used for hundreds of years by the great masters of the Tibetan traditions. Unlike in the Western psychological approach to dreams, the ultimate goal of Tibetan dream yoga is the recognition of the nature of mind or enlightenment itself.

This classic introduction to the psychology of Carl Gustav Jung is important because it is the only English original text he sanctioned in his lifetime. In his personal foreword, he wrote: 'Mrs Frieda Fordham has undertaken the by no means easy task of producing a readable resumé of all my various attempts at a better and more comprehensive understanding of the human psyche. She has delivered a fair and simple account of the main aspects of my psychological work. I am indebted to her for this admirable piece of work.'

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.

A classic in the Jungian literature, written by one of Jung's most distinguished collaborators.
