What is stoicism?

The philosophy of stoicism as espoused by the Greeks (notably Zeno, 334 BC-262 BC) saw negative emotions as failures to act with wisdom and virtue. They believed that virtue and ethics were features of nature, and that self-control and reason were important to attaining well-being and happiness.

The modern description of a stoic reflects one general principle of Stoicism : the avoidance of destructive emotions (fear, hate, envy). This is sometimes simplified to be controlling all strong emotions, regardless of their source.
