Final answer:
Cicero defines the six categories of people in Catalina's network in his 'Second Speech Against Catiline', particularly in sections 21 and 22, portraying them as morally decadent and dangerous to Roman society.
Step-by-step explanation:
In his Second Speech Against Catiline, specifically in sections 21 and 22, Cicero defines the six categories of people in Catalina's network. Cicero describes Catiline's closest allies with much disdain, highlighting their decadent lifestyle and dangerous ambitions. These individuals are characterized by Cicero as well-groomed, effeminate, and indulgent in excesses like gambling and adultery, a reflection of the moral decay Cicero attributes to Catiline's circle. He emphasizes that Catiline's followers have not only learned to engage in hedonistic pleasures but are also skilled in violence, such as wielding daggers and administering poison. Through this speech, Cicero intended to rally the Senate and the Roman people against Catiline and his conspirators by casting them as a direct threat to the traditional social and moral order of the Roman Republic.
