SAY the name “Baron Cohen” and most people will think of Sacha Baron Cohen wearing his lime-green “mankini” in the hilarious film Borat. But it was a different Baron Cohen who was in Pietermaritzburg last week — and he was much more conventionally dressed. “We are at a time of little hope and great need for an optimistic vision,” he says, explaining that as president of Idea, he has had contact with governments all over the world, and that there is enormous concern about how to find an education model that is appropriate to prepare young people for life in our multicultural societies. “The 19th-century model that has been used for education is in crisis in the 21st century,” he says. He talks about Finland, which is considered to have a good education system, but has just seen its second school shooting in a year.
