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'.

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.

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.

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.

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.

Plotinus (204/5 -270 CE), born in Lycopolis, Egypt, when it was part of the Roman Empire, was a major figure in the philosophical school later called Neoplatonism. Neoplatonists viewed reality as deriving from a single force or figure expressed as 'the One'. Two further concepts from Plotinus, 'the Intellect' and 'the Soul', are also principal features of his philosophy. These proposals led to the work of Plotinus forming a bridge between Plato and the monotheistic religions of Christianity, Judaism, and Islam as well as Gnosticism.

In Trauma and the Soul, Donald Kalsched continues the exploration he began in his first book, The Inner World of Trauma (1996)—this time going further into the mystical or spiritual moments that often occur around the intimacies of psychoanalytic work. Through extended clinical vignettes, including therapeutic dialogue and dreams, he shows how depth psychotherapy with trauma’s survivors can open both analytic partners to "another world" of non-ordinary reality in which daimonic powers reside, both light and dark.

In 1929, Martin Heidegger (1889-1976) published his remarkable book Kant and the Problem of Metaphysics. The Kantbuch, as Heidegger often called it, is regarded by many as a vital supplement to the unfinished second part of Heidegger’s most influential work, Being and Time, which was published two years earlier in 1927. 

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.

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.
