Seneca the Younger was a Roman philosopher, statesman, and playwright born around 4 BCE in Corduba, Hispania. He is best known for his works on Stoicism, a philosophy that emphasizes rationality and self-control. Seneca served as an advisor to Emperor Nero, but their relationship became strained, leading to his forced suicide in 65 CE. His writings, including letters and essays, explore themes of ethics, morality, and the nature of happiness. Seneca's influence extends beyond philosophy; his tragedies, such as Phaedra and Thyestes, have impacted later literature and drama, making him a significant figure in both philosophy and the arts.
