Some conservative senators, especially friends of Tacitus and Pliny, are scheming to bring about an end to Domitian's reign. Domitian didn't know which specific senators were plotting against him so he took several precautions. Since many of these senators are believers in the Stoic philosophy, Domitian has expelled all philosophers from Rome to prevent a larger conspiracy from forming.
