Zeno of Citium

Zeno of Citium was an ancient Greek philosopher who founded Stoicism, a philosophy emphasizing self-control, resilience, and rational understanding of nature and reality. He believed that by mastering our emotions and living in harmony with the universe's natural order, we could attain inner peace and virtue. Zeno taught that external events are outside our control, but our responses are within our power, encouraging us to focus on what we can influence. His ideas have influenced principles of modern personal development and ethics, emphasizing reason, discipline, and acceptance of life's challenges.
