Seneca addresses the central question of ancient philosophy: what constitutes human happiness? In twenty-five chapters he argues that happiness cannot be found in pleasure, wealth, or popular opinion, but only in virtue and the life of reason. Drawing on Stoic principles, he shows that the man who has mastered his passions and submitted his will to nature is truly happy — regardless of external fortune. One of the most direct and readable statements of Stoic ethics ever written.
