Seneca\'s letters to his friend Lucilius are an introduction to Stoic philosophy. The author is not aiming for a systematic presentation; he is concerned with showing ways of philosophically overcoming concrete problems of human life. Topics such as loneliness, illness and death affect us in the same way as they did people 2000 years ago. \"You still remember the joy you felt when you took off the boy\'s toga and put on the man\'s and were led into the forum. Expect an even greater one when you shed your boyish spirit and philosophy accepts you among men.\"
