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.'

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 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 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'.

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.

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.  

As philosophy professor Taylor Carman explains in his helpful introduction, Edmund Husserl (1859-1938) was the founder of modern phenomenology, one of the most important and influential movements of the 20th century. Ideas, published in 1913 – its full title is Ideas for a Pure Phenomenology and Phenomenological Philosophy – was the key work. It is arguably ‘the most fundamental and comprehensive statement of the fundamental principles of Husserl’s mature philosophy’. 

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?

Ordinary Men is the true story of Reserve Police Battalion 101 of the German Order Police, which was responsible for mass shootings as well as round-ups of Jewish people for deportation to Nazi death camps in Poland in 1942. Browning argues that most of the men of  RPB 101 were not fanatical Nazis but, rather, ordinary middle-aged, working-class men who committed these atrocities out of a mixture of motives, including the group dynamics of conformity, deference to authority, role adaptation, and the altering of moral norms to justify their actions.

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 1957, four years before his death, Carl Gustav Jung, psychiatrist and psychologist, began writing his life story. But what started as an exercise in autobiography soon morphed into an altogether more profound undertaking.

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.

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.

Fyodor Dostoyevsky is a titanic figure among the world's great authors, and The Brothers Karamazov is often hailed as his finest novel. A masterpiece on many levels, it transcends the boundaries of a gripping murder mystery to become a moving account of the battle between love and hate, faith and despair, compassion and cruelty, good and evil.
