Lucius Annaeus Seneca (c. 4 BCE – 65 CE), commonly known as Seneca the Younger, was a Roman Stoic philosopher, statesman, and dramatist of the Silver Age of Latin literature. As a philosopher, he is most known for his works on Stoicism and ethics, one such notable work being 'On the Firmness of the Wise Man' (De Constantia Sapientis), wherein he contemplates the stoic ideal of steadfastness and the ability to maintain a moral and emotional equilibrium under duress. Seneca's literary style is marked by its aphoristic approach and rhetorical elegance, making his philosophical treatises both insightful and accessible. Along with works on ethics, Seneca penned a number of tragedies, which are regarded for their psychological insight and portrayal of passion. His influence on later generations was profound, shaping the thoughts of early Christian writers and the Renaissance humanists. Despite a controversial career as an advisor to emperor Nero and an ordered suicide by the same, Seneca's intellectual legacy endures through his penetrating advice on life's moral challenges, the pursuit of virtue, and the human condition.
