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.

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close friend Heinrich Köselitz and his sister Elizabeth Förster-Nietzsche to go through the remaining notebooks and unpublished writings, choosing sections of particular interest to produce The Will to Power, giving it the subtitle An Attempted Transvaluation of All Values. 

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.'

Though Twilight of the Idols (written in a week in 1888 and subtitled How to Philosophise with a Hammer) came near the end of Nietzsche’s creative life, he actually recommended it as a starting point for the study of his work. This was because from the beginning he viewed it as an introduction to his wide-ranging views.  

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".

One of Nietzsche’s earliest works, The Birth of Tragedy (1872) is a remarkable source of inspiration. It is here that the philosopher expresses his frustration with the contemporary world and urges man to embrace Dionysian energy once more. He refutes European culture since the time of Socrates, arguing that it is one-sidedly Apollonian and prevents man from living in optimistic harmony with the sufferings of life.

In Twilight of the Idols, Nietzsche criticizes German culture of the day as unsophisticated and nihilistic, and shoots some disapproving arrows at key French, British, and Italian cultural figures who represent similar tendencies. In contrast to all these alleged representatives of cultural "decadence", Nietzsche applauds Caesar, Napoleon, Goethe, Thucydides, and the Sophists as healthier and stronger types. The book states the transvaluation of all values as Nietzsche's final and most important project, and gives a view of antiquity wherein the Romans for once take precedence over the ancient Greeks.

On the Genealogy of Morality (The Genealogy of Morals) is an 1887 book by German philosopher Friedrich Nietzsche. It consists of a preface and three interrelated essays that expand and follow through on concepts Nietzsche sketched out in Beyond Good and Evil. The three essays trace episodes in the evolution of moral concepts with a view to confronting moral prejudices, specifically those of Christianity and Judaism. Some Nietzsche scholars consider Genealogy to be a work of sustained brilliance and power as well as his masterpiece.

Also sprach Zarathustra was conceived and written by Friedrich Nietzsche during the years 1881-1885; the first three Parts were published in 1883 and 1884. The book formed part of his "campaign against morality", in which Nietzsche explored the ethical consequences of the "death of God".

 Untimely Considerations contain four essays: 'David Strauss - Writer and Confessor'; 'On the Use and Abuse of History for Life'; 'Schopenhauer as Educator'; and 'Richard Wagner at Bayreuth'. The essays date from the early part of Nietzsche’s life when his Romantic view on life and art was coloured by the powerful writings and personalities of such figures as Schopenhauer and Wagner - as the titles of two of the essays proclaim. Published between 1873 and 1876, they were presented under the umbrella title 'Unzeitgemässe Betrachtungen'.

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.

Who was Friedrich Nietzsche? This lonely and chronically ill, yet passionate, daring, and complex man is perhaps the most mysterious and least understood of all contemporary philosophers. Why are his brilliant insights so relevant for today? How did he become the most misinterpreted and unfairly maligned intellectual figure of the last two centuries?

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.

Aion is one of the major works of C.G. Jung's later years. The title comes from the Greek word for aeon or age and refers to the age of Christianity, for, in Aion, Jung is concerned with the collective psychic development that the Christian era represents. How did it come about when it did? What psychic change did it represent? In exploring these questions, Jung (1875-1961) draws upon Christian symbolism and, in particular, the figure of Christ as a case study in the archetype of the Self. 

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.
