Of a Happy Life is an essay written by Seneca around the year 58 AD. It was intended for his older brother Gallio, to whom Seneca also dedicated his dialogue entitled De Ira ('On Anger'). 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.
