Re: They had a better justice system back then
^ Now that you are studying..I think you should read History of Kknowledge by Charles Van Doren (You might recognize his name from the movie Quiz Show..yup, the Columbia University professor)..HUman knowledge is a collective phenoenon..human beings have this uncanny ability to retain and adopt adn adapt to changing intellectual and physical environs retaining the best practices wherever they are found. A system that cannot become a best practice is a failure of sorts. We learned throughout history to improve and evolve..it is in our genes. It is always for the better.
HUman lives are much better now than they ever were before..it is because of our adoption of best practices (i.e. tried and true systems that can evolve)
