Here are three key works by Sigmund Freud which, published in the first decades of the 20th century, underpinned his developing views and had such a dramatic effect on world society. In the uncompromising Three Essays on the Theory of Sexuality (1905), he declared that 'sexual aberrations' are not limited to the insane but exist in 'normal' people to a greater or lesser degree. The three essays are divided between sexual perversions, childhood sexuality and puberty.

Among the many important historical documents from the Classical world of Greece and Rome The Antiquities of the Jews by Flavius Josephus is one of the most distinctive and characterful. Josephus (37-c100 CE) set out with the clear purpose of telling the history of the Jews from the creation in Genesis to the Jewish revolt against the Romans in 66 CE. Born in Jerusalem as Yosef ben Matityahu, he rose to become a leading participant in the First Jewish Revolt (66-73 CE).

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.

This Leibniz collection contains some of the philosopher’s most important works and ideas, spans three decades and illuminates the fascinating intellectual journey undertaken by him in his quest for truth. A prodigious polymath, Leibniz was a mathematician, philosopher, physicist and statesman and engaged with a sweeping range of ideas and disciplines, striving throughout his life to be at the cutting edge of scientific thinking. These Principal Essays are arranged in chronological order.

Sigmund Freud (1856-1939) is remembered as the father of psychoanalysis. Civilization and Its Discontents (1930) is one of his key works, written three decades after his seminal book The Interpretation of Dreams. In it he considers the conflict between the needs of the individual acting both egotistically and altruistically in the pursuit of happiness and the myriad demands of civilised society and the ensuing tensions this clash of needs and demands generates.

One of the finest German medieval epic poems, The Lay of the Nibelungs is perhaps best known now as one of the principal sources for Wagner’s four-part music drama The Ring of the Nibelung. It is easy to see how Wagner was enthralled by the story and the poetry for the power of the tale drives the narrative: intense love, loyalty, jealousy, murder, duty, honour and massacre are all interwoven into a classic.

Matter and Memory, (Matière et Mémoire), published in 1896, was the second book written by Henri Bergson (1859-1941), one of the leading French philosophers of his age. It followed Time and Free Will (1889) and helped to establish him as a major force in anti-mechanistic thought, opposing the trend towards uncompromisingly secular and scientific views. However, when Matter and Memory appeared, Bergson was 39 and had yet to become the hugely influential figure he became in the first decades of the 20th century.

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'.

The Pillow Book of Sei Shōnagon is a fascinating, detailed account of Japanese court life in the closing years of the 10th century. Written by a lady of the court at the height of Heian culture, this book enthrals with its lively gossip, witty observations and subtle impressions. Lady Shōnagon was an erstwhile rival of Lady Murasaki, whose novel, The Tale of Genji, fictionalized the elite world Lady Shōnagon so eloquently relates.

Simone de Beauvoir’s essential masterwork is a powerful analysis of the Western notion of "woman", and a revolutionary exploration of inequality and otherness. This unabridged edition of the text reinstates significant portions of the original French text that were cut in the first English translation, and is now available on audio for the very first time. Vital and groundbreaking, Beauvoir’s pioneering and impressive text remains as pertinent today as when it was first published, and will continue to provoke and inspire generations of men and women to come.

Alain de Botton has performed a stunning feat: He has transformed arcane philosophy into something accessible and entertaining, useful and kind.

In this study, Fromm argues that man needs to analyze his unconscious thoughts, his dreams, and his conscious fantasies, as they reflect a universal and symbolic representation of himself.

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 human body is the most fraught and fascinating, talked-about and taboo, unique yet universal fact of our lives.

Carl Jung's Collected Papers on Analytical Psychology gathers in one volume some of his most important and influential shorter writings, and also some pieces that, from our perspective almost a century later, seem quaint or even idiosyncractic. The volume provides wonderful insight into his mind and thought as he reached a position of prominence in the world of psychoanalysis.

Sigmund Freud revolutionized the way in which we think about ourselves. From its beginnings as a theory of neurosis Freud developed psychoanalysis into a general psychology, which became widely accepted as the predominant mode of discussing personality and interpersonal relationships. Anthony Storr goes one step further and investigates the status of Freud's legacy today and the disputes that surround it.

What are the most common dreams and why do we have them? What does a dream about death mean? What do dreams of swimming, failing, or flying symbolize? First published by Sigmund Freud in 1899, The Interpretation of Dreams considers why we dream and what it means in the larger picture of our psychological lives.

Although the theories presented in this book, a 1915 edition of the lectures Jung presented at Fordham University, are now thoroughly outdated, this book is still a fascinating glimpse of Jung's mind at a crucial time in his life. Just three years previously, he had struck out on his own, publishing his Wandlungen und Symbole der Libido, known in English as Psychology of the Unconscious.

First released more than 40 years ago, Love and Limerence has become a classic in the psychology of emotion. As relevent today as it was then, this book offers insight into love, infatuation, madness, and all flavors of emotion in between.

The Varieties of Religious Experience is considered to be the classic work in the field. To quote Wikipedia, "James was most interested in understanding personal religious experience. The importance of James to the psychology of religion - and to psychology more generally - is difficult to overstate. He discussed many essential issues that remain of vital concern today. What makes James writing so special is that he could take a very complex subject and, without watering it down, make it understandable to 'the rest of us.'"

In this study, Fromm argues that man needs to analyze his unconscious thoughts, his dreams, and his conscious fantasies, as they reflect a universal and symbolic representation of himself.

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.

Bolder even than the ambitious books for which Stephen Greenblatt is already renowned, The Rise and Fall of Adam and Eve explores the enduring story of humanity's first parents. Comprising only a few ancient verses, the story of Adam and Eve has served as a mirror in which we seem to glimpse the whole long history of our fears and desires, as both a hymn to human responsibility and a dark fable about human wretchedness.
