Written in Greek by an intellectual Roman emperor without any intention of publication, the Meditations of Marcus Aurelius offer a wide range of fascinating spiritual reflections and exercises developed as the leader struggled to understand himself and make sense of the universe. Spanning from doubt and despair to conviction and exaltation, they cover such diverse topics as the question of virtue, human rationality, the nature of the gods and Aurelius's own emotions. 

Seeing self-possession as the key to an existence lived 'in accordance with nature', the Stoic philosophy called for the restraint of animal instincts and the importance of upright ethical ideals and virtuous living.

Thus Spoke Zarathustra is one of the most extraordinary - and important - texts in Western philosophy. It was written by Friedrich Nietzsche between 1883 and 1885. He cast it in the form of a novel in the hope that his urgent message of the 'death of God' and the rise of the superman (Ubermensch) would have greater emotional as well as intellectual impact.

Beyond Good and Evil confirmed Nietzsche's position as the towering European philosopher of his age. The work dramatically rejects traditional Western thought with its notions of truth and God, good and evil. Nietzsche seeks to demonstrate that the Christian world is steeped in a false piety and infected with a 'slave morality'. With wit and energy, he turns from this critique to a philosophy that celebrates the present and demands that the individual impose their own 'will to power' upon the world.

Epictetus, a Greek stoic and freed slave, ran a thriving philosophy school in Nicropolis in the early second century AD. His animated discussions were celebrated for their rhetorical wizardry and were written down by Arrian, his most famous pupil. Together with the Enchiridion, a manual of his main ideas, and the fragments collected here, The Discourses argue that happiness lies in learning to perceive exactly what is in our power to change and what is not, and in embracing our fate to live in harmony with god and nature.

Praised by the finest military minds in history and said to have influenced no lesser lights than Frederick the Great and Napoleon, the Art of War is essential for anyone who wants to understand the history and theory of war in the West and for those familiar with The Prince and Discourse on Livy who seek to explore more fully the connection between war and politics in Machiavelli's thought.

In the first century BC, Marcus Tullius Cicero, orator, statesman and defender of republican values, created these philosophical treatises on such diverse topics as friendship, religion, death, fate and scientific inquiry. A pragmatist at heart, Cicero's philosophies were frequently personal and ethical, drawn not from abstract reasoning but through careful observation of the world. The resulting works remind us of the importance of social ties, the questions of free will and the justification of any creative endeavour.
