The Consolation of Philosophy is one of the key works in the rich tradition of Western philosophy, partly because of the circumstances in which it was written. Anicius Manlius Severinus Boethius (c480-c524) was of aristocratic Roman birth and became consul and then master of offices at Ravenna, one of the highest posts under the Ostrogothic Roman ruler Theodoric. But Boethius was unjustly charged with treason in 524, and this led to house arrest, then torture and execution.

This famous work by Lucretius is a masterpiece of didactic poetry, and it still stands today as the finest exposition of Epicurean philosophy ever written. The poem was produced in the middle of first century B.C., a period that was to witness a flowering of Latin literature unequaled for beauty and intellectual power in subsequent ages. The Latin title, De Rerum Natura, translates literally to On the Nature of Things and is meant to impress the reader with the breadth and depth of Epicurean philosophy.

As former tutor and adviser to Emperor Nero, philosopher and statesman Seneca was acutely aware of how short life can be - his own life was cut short when the emperor ordered him to commit suicide (for alleged involvement in a conspiracy). And Seneca proved true to his words - his lifelong avowal to Stoicism enabled him to conduct himself with dignity to the end. During his rich and busy life, Seneca wrote a series of essays that have advised and enriched the lives of generations down to the present day.

In How to Be an Epicurean, philosopher Catherine Wilson shows that Epicureanism isn't an excuse for having a good time: It's a means to live a good life. Although modern conveniences and scientific progress have significantly improved our quality of life, many of the problems faced by ancient Greeks - love, money, family, politics - remain with us in new forms. To overcome these obstacles, the Epicureans adopted a philosophy that promoted reason, respect for the natural world, and reverence for our fellow humans.

The Enchiridion is the famous manual of ethical advice given in the second century by the Stoic philosopher Epictetus. Born to a Greek slave, Epictetus grew up in the environment of the Roman Empire and, having been released from bonds of slavery, became a stoic in the tradition of its originators, Zeno (third Century BCE) and Seneca (first century CE).

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. Seneca's writings are a profound, powerfully moving and inspiring declaration of the dignity of the individual mind. 

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.

“A faithful translation is rare; a translation which preserves intact the original text is very rare; a perfect translation of Montaigne appears impossible. Yet Donald Frame has realized this feat. One does not seem to be reading a translation, so smooth and easy is the style; at each moment, one seems to be listening to Montaigne himself - the freshness of his ideas, the unexpected choice of words. Frame has kept everything.” (Andre Maurois, The New York Times Book Review)

Towards the end of his life, Seneca the Younger (c4 BCE-65 CE) began a correspondence with a friend in Sicily, later collected under the title The Moral Epistles. In these 124 letters, Seneca expresses, in a wise, steady and calm manner, the philosophy by which he lived - derived essentially from the Stoics. The letters deal with a variety of specific topics - often eminently practical - such as 'On Saving Time', 'On the Terrors of Death', 'On True and False Friendships', 'On Brawn and Brains' and 'On Old Age and Death'.

Although it was originally published in 1892, Early Greek Philosophy by John Burnet remains unquestionably one of the most respected and admired surveys of the pre-Socratics. It is an illuminating springboard into classical Greek philosophy.

Nearly six hundred years ago, a short, genial, cannily alert man in his late 30s took a very old manuscript off a library shelf, saw with excitement what he had discovered, and ordered that it be copied. That book was the last surviving manuscript of an ancient Roman philosophical epic by Lucretius—a beautiful poem containing the most dangerous ideas: that the universe functioned without the aid of gods, that religious fear was damaging to human life, and that matter was made up of very small particles.

Epictetus (c. AD 50-135) was a former Roman slave (he was also lame in one leg, and walked with a crutch) who went on to become a great teacher. His philosophy, Stoicism, was practical, not theoretical - aimed at relieving human suffering here and now. The Manual is a collection of Epictetus' essential teachings and pithy sayings, compiled by one of his students.

Philosophical Investigations was published in 1953, two years after the death of its author. In the preface written in Cambridge in 1945 where he was professor of philosophy he states: ‘Four years ago I had occasion to re-read my first book (the Tractatus Logico-Philosophicus) and to explain its ideas to someone. It suddenly seemed to me that I should publish those old thoughts and the new ones together: that the latter could be seen in the right light only by contrast with and against the background of my old way of thinking.’

This Leibniz collection contains some of the philosopher’s most important works and ideas, spans three decades and illuminates the fascinating intellectual journey undertaken by him in his quest for truth. A prodigious polymath, Leibniz was a mathematician, philosopher, physicist and statesman and engaged with a sweeping range of ideas and disciplines, striving throughout his life to be at the cutting edge of scientific thinking. These Principal Essays are arranged in chronological order. 

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.
