What did voltaire mean by "envy and ignorance did not hold themselves beaten"?

The envy and ignorance that existed didn't change or go away because they are inherit to human nature. No political system can make a evolutionary change on human nature. That must happen over time.

idk you know what i mean hahahaha

the hyksos invasion. the hyksos were able to attack egypt successfully because of their skills in using bronze weapons, composite bows and the use of the horse and chariot during the invasion. although the egyptians depict a barbarian-type overthrow, the truth is the seizure was likely a relatively peaceful one.
