Zeno of Citium was a Greek philosopher who founded the school of philosophy known as Stoicism around 300 BCE. Born in Citium, Cyprus, he moved to Athens, where he studied under various philosophers, including Crates of Thebes. Zeno emphasized the importance of virtue, reason, and living in harmony with nature.
Stoicism teaches that individuals should focus on what they can control and accept what they cannot. Zeno's ideas influenced many later philosophers, including Seneca and Marcus Aurelius, and continue to be relevant in modern discussions about ethics and personal resilience.
