''It is philosophy that has the duty of protecting us ... without it no one can lead a life free of fear or worry''For several years of his turbulent life, in which he was dogged by ill health, exile and danger, Seneca was the guiding hand of the Roman Empire. This selection of Seneca''s letters shows him upholding the ideals of Stoicism - the wisdom of the self-possessed person immune to life''s setbacks - while valuing friendship and courage, and criticizing the harsh treatment of slaves and the cruelties in the gladiatorial arena. The humanity and wit revealed in Seneca''s interpretation of Stoicism is a moving and inspiring declaration of the dignity of the individual mind.Selected and translated with an Introduction by Robin Campbell
