It’s said that Leonardo da Vinci was looking at a marble block so concentrated that somebody asked him what he was thinking of. Leonardo said that his next statue was already inside that block, so the only thing he had to do was removing the pieces of marble which were not necessary for the sculpture.
Creativity, like in Leonardo’s block is inside us, but most people are not able to discover their own capacities, so the school could be the best place to discover and develop them. However, from my point of view, what Ken Robinson explains is only possible in developed countries. In many Asian or African countries, where most of the people can neither read nor write, discovering creativity in the children could be, unfortunately, a secondary target.
