On the Happy Life

On the Happy Life is a dialogue written by Seneca the Younger around the year 58 AD, intended for his older brother Gallio. It is divided into 28 chapters that present the moral thoughts of Seneca at their most mature. Seneca explains that the pursuit of happiness is the pursuit of reason - reason meant not only using logic, but also understanding the processes of nature.

Lucius Annaeus Seneca the Younger usually known as Seneca, was a Roman Stoic philosopher, statesman, dramatist, and, in one work, satirist, from the post-Augustan age of Latin literature.
