'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.

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.

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'.

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).

Epictetus, one of the greatest of the ancient thinkers, believed that the primary mission of philosophy is to help ordinary people meet the challenges of daily life and deal with losses, disappointments, and grief. His prescription for the good life: master desires, perform one's duties, and learn to think clearly about oneself and the larger community. This recording includes an interview with philosopher Jacob Needleman on the significance of Epictetus' work.
