I believe that the purpose of Education in 2021 AD is the same as it was in 2021 BC, which is to guarantee our species' survival by providing tools to integrate individuals into society.
If you have children in your life, I strongly suggest you read a large variety of folktales, including stories from all continents. Each population uses the symbols available in their environment to evoke and embody the most primitive human impulses... the signs might look different. Still, they are all talking about the same subject. We can develop empathy and a sense of belonging to the World's Community by exposing our children to as many different cultures as possible.
