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.

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.

One of the most significant books ever written by a head of state, the Meditations are a collection of philosophical thoughts by the Emperor Marcus Aurelius (121 - 180 ce). Covering issues such as duty, forgiveness, brotherhood, strength in adversity and the best way to approach life and death, the Meditations have inspired thinkers, poets and politicians since their first publication more than 500 years ago. Today, the book stands as one of the great guides and companions - a cornerstone of Western thought.

The Tao of Seneca (volumes 1-3) is an introduction to Stoic philosophy through the words of Seneca. If you study Seneca, you'll be in good company.

Immanuel Kant’s Critique of Pure Reason can lay claim to being the most important single work of modern philosophy, a work whose methodology, if not necessarily always its conclusions, has had a profound influence on almost all subsequent philosophical discourse. In this work Kant addresses, in a groundbreaking elucidation of the nature of reason, the age-old question of philosophy: “How do we know what we know?” and the limits of what it is that we can know with certainty.

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'.

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.

'On Anger' is one of Seneca's most important essays. At some length he investigates the nature of anger: how and why it emerges, the effect it has on the individual and those to whom it is directed, and how to manage it and prevent it even from arising. For, Seneca considers, anger simply serves no purpose - it does not bring courage in war, prevent others misbehaving or punish miscreants. In short it has a negative effect on all. In 'On Leisure' he takes a short look at what is really meant by the term.
