Seneca, full name Lucius Annaeus Seneca, was a prominent Roman Stoic philosopher, statesman, and playwright who lived from around 4 BCE to 65 CE. He is often referred to as Seneca the Younger to distinguish him from his father, Seneca the Elder. He was a leading figure in the Stoic school of philosophy, which emphasized the importance of virtue, reason, and self-control in achieving a tranquil and contented life. His writings, including letters, essays, and dialogues, explore Stoic principles and provide practical guidance on living a virtuous life.

Seneca's works remain widely read and studied today, and his contributions to Stoic philosophy have left an enduring legacy in the history of Western thought.
