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 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.'

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 was one of the most revolutionary thinkers in Western philosophy and Thus Spoke Zarathustra remains his most influential work. It describes how the ancient Persian prophet Zarathustra descends from his solitude in the mountains to tell the world that God is dead and that the Superman, the human embodiment of divinity, is his successor. With blazing intensity, Nietzsche argues that the meaning of existence is not to be found in religious pieties or meek submission, but in an all-powerful life force: passionate, chaotic and free.

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close friend Heinrich Köselitz and his sister Elizabeth Förster-Nietzsche to go through the remaining notebooks and unpublished writings, choosing sections of particular interest to produce The Will to Power, giving it the subtitle An Attempted Transvaluation of All Values.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

Friedrich Nietzsche (1844-1900) is one of the towering intellectual figures of the 19th century, a philologist, philosopher and poet of profound complexity and range whose writings in moral philosophy continue to resonate in the present day. The Dawn of Day (Morgenröte), first published in 1881, marked a clear shift in his thinking and prefigures many of the ideas that would be further developed in his later writings. The clue is in the title, sometimes translated as Dawn or Morning, which suggests the beginning of a different awareness.

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.

From the perspective of an unbeliever, Fear and Trembling explores the paradox of faith, the nature of Christianity, and the complexity of human emotion. Kierkegaard examines the biblical story of Abraham, who was instructed to sacrifice his son Isaac, and forces us to consider Abraham's state of mind. What drove Abraham, and what made him carry out such an absurd and extreme request from God? Kierkegaard argues that Abraham's agreement to sacrifice Isaac, and his suspension of reason, elevated him to the highest level of faith.

In an incisive, thorough analysis of the current international situation, Noam Chomsky argues that the United States, through its military-first policies and its unstinting devotion to maintaining a world-spanning empire, is both risking catastrophe and wrecking the global commons.
