Prospect's World Thinkers 2013

       An internet poll asking who the world's leading thinkers are sounds like the ultimate in dubious exercises, but that's what Prospect did, and "more than 10,000 votes from over 100 countries" later the results are now in.
       Not many creative writers rate, but among those who do are:

• 15. Arundhati Roy
• 33. Hilary Mantel
• 35. Zadie Smith
• 42. David Grossman

       And, in 64th position: The New York Review of Books editor Robert Silvers.
