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.'

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his close friend Heinrich Köselitz and his sister Elizabeth Förster-Nietzsche to go through the remaining notebooks and unpublished writings, choosing sections of particular interest to produce The Will to Power, giving it the subtitle An Attempted Transvaluation of All Values. 

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".

The Antichrist and Ecce Homo were two of the last works written by Friedrich Nietzsche just before his mental collapse in 1889. Though both written in 1888, they are very different in content and style. In The Antichrist, Nietzsche expands on his view that the submissive nature of Christianity undermined Western society, depressing and sapping energy.

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.

The Origins and History of Consciousness draws on a full range of world mythology to show how individual consciousness undergoes the same archetypal stages of development as human consciousness as a whole. Erich Neumann was one of C. G. Jung's most creative students and a renowned practitioner of analytical psychology in his own right. In this influential book, Neumann shows how the stages begin and end with the symbol of the Uroboros, the tail-eating serpent.

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'.

A predecessor to such monumental works such as Crime and Punishment and The Brothers Karamazov, Notes From Underground represents a turning point in Dostoyevsky's writing towards the more political side.

In this work, we follow the unnamed narrator of the story, who, disillusioned by the oppression and corruption of the society in which he lives, withdraws from that society into the underground.

Paradise Lost, along with its companion piece, Paradise Regained, remain the most successful attempts at Greco-Roman style epic poetry in the English language. Remarkably enough, they were written near the end of John Milton's amazing life, a bold testimonial to his mental powers in old age. And, since he had gone completely blind in 1652, 15 years prior to Paradise Lost, he dictated it and all his other works to his daughter.

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.  

What is life? What is my place in it? What choices do these questions obligate me to make? More than a half-century after it burst upon the intellectual scene - with roots that extend to the mid-19th century - Existentialism's quest to answer these most fundamental questions of individual responsibility, morality, and personal freedom, life has continued to exert a profound attraction.

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.

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.

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.

Friedrich Nietzsche (1844-1900) has influenced philosophers such as Martin Heidegger, Jean-Paul Sartre, Oswald Spengler, George Grant, Emil Cioran, Albert Camus, Ayn Rand, Jacques Derrida, Leo Strauss, Max Scheler, Michel Foucault and Bernard Williams. His writings on aesthetics, language, truth, morality, cultural theory, history, nihilism, power, and the meaning of existence have exerted a vast influence on Western philosophy and intellectual history.
