THERE'S a crisis looming over Bengal. The crisis of heroism. Or the crisis spawned by the drought of heroes, if you like. So when the news arrived from Calcutta on the afternoon of October 14th that Amartya Sen had won the Nobel Prize, chief minister Jyoti Basu interrupted another banal discourse on the virtues of the work ethic at a meeting in rust-belt Siliguri and harrumphed: "I have a piece of good news. It is a matter of pride that Dr Amartya Sen has won the Nobel Prize. He is a Beng-ali...he is an Indian." A frazzled audience of teachers, students and apparatchiki jumped from the seats and applauded.
