On The Firmness Of The Wise
De Constantia Sapientis (English: On the Firmness of the Wise) is a moral essay written by Seneca the Younger, a Roman Stoic philosopher, sometime around 55 AD. The work celebrates the imperturbility of the ideal Stoic sage, who with an inner firmness, is strengthened by injury and adversity.
Seneca’s essay “On the Firmness of the Wise Person” (Latin: De Constantia Sapientis) presents stoicism in very clear and practical terms. It is one of the few essays exclusively dedicated to functional stoicism that Seneca wrote. Essays on stoicism often present the school of thought in hypothetical terms, however, this essay focuses on constructive and practicable advice.
Seneca the Younger (c. 4 BC – AD 65), fully Lucius Annaeus Seneca and also known simply as Seneca (/ˈsɛnɪkə/), was a Roman Stoic philosopher, statesman, dramatist, and—in one work—humorist of the Silver Age of Latin literature. As a tragedian, he is best-known for his Medea and Thyestes.
He was a tutor and later advisor to emperor Nero. He was forced to take his own life for alleged complicity in the Pisonian conspiracy to assassinate Nero. However, some sources state that he may have been innocent. His father was Seneca the Elder, his elder brother was Lucius Junius Gallio Annaeanus, and his nephew was the poet Lucan.
