Seneca, a Roman philosopher and statesman, lived from 4 BCE to 65 CE. He is best known for his contributions to Stoicism, a school of thought that emphasizes rationality and self-control. Seneca's writings, including letters and essays, explore themes of ethics, the nature of happiness, and the importance of virtue. As a tutor and advisor to Emperor Nero, Seneca's life was marked by political intrigue and personal conflict. Despite his wealth and influence, he faced exile and ultimately took his own life under Nero's orders. His works continue to be studied for their insights into human behavior and moral philosophy.
