Why were some political factions dissatisfied with the constitutional settlement of 1791?

The French constitution was completed on September 3 1791 and sent to the king for acceptance. The constitution confirmed the existence of an hereditary monarchy with limited veto powers:the king could temporarily stall legislation with his veto, but he could not veto any legislation permanently. The king was to have no control over the army, no authority over local governments, and he could send no representatives to serve in parliament. There was to be a single legislative house - rather than two houses as in the United States. All judges were to be elected, and voting was to be by all who paid taxes equivalent to three days wages or more. The constitution repeated some of what was said in the Declaration of the Rights of Men and Citizens: all men were said to be born with equal rights, and everyone was said to be free to speak, write or print his opinions provided he did not abuse this privilege. And the amount of taxes that a person paid was to be based on the amount of wealth he possessed. 

Herodotus taught that absolute right and wrong did exist.
