Cato's Letter No. 2 speaks to the Founders' usurping their authority. Right out of the bag, they lied to their countrymen. They were not sent to Philadelphia to replace the Articles of Confederation, but to amend and consequently strengthen them!
Cato takes issue with one Caesar, who is attempting to insult and browbeat the people into buying a bill of goods.
Cato claims that The Articles are serviceable, notwithstanding the arguments of the Founders. Cato is worried that the Framers are more conquerors than liberators, and tells his fellow Americans to be on the lookout for attempted deceptions.
