SOCIETY ADVANCES MOST WHEN PEOPLE BREAK FROM THE TRADITIONS OF THEIR PREDECESSORS.
My personal opinion
I remember when I was a kid whatching a Disney movie called Meet the Robinsons, it is such a beautiful movie about how important is family but it also has a powerful message.
To progress as humans we must let some things go, even though it may hurt us sometimes. But how are we suposse to know what things to let go and what things to hold on to?
So what Walt Disney said was:
Finally we can say that change is always good, but we have to evaluate what things really deserve to change or be eliminated. Having a neutral point of view in this matter may be hard, but it is what is necessary in order to make the right choices, not only for us, as human beings, but for animals too.
