The ancient philosophical school that emphasized the pursuit of virtue and wisdom is Stoicism. Founded in Athens by Zeno of Citium in the early 3rd century BCE, Stoicism teaches that virtue, understood as wisdom, is the highest good. Adherents believe that one can achieve tranquility by understanding and accepting the natural order of the world. This philosophy encourages the development of self-control, resilience, and rational thinking. Prominent Stoic philosophers, such as Seneca, Epictetus, and Marcus Aurelius, have greatly influenced both ancient and modern ethical thought, providing guidance on how to lead a fulfilling life amidst adversity.
