In 2005, Prospect and Foreign Policy asked you to vote for your top global public intellectuals from a longlist of 100 (see the results here). This year we are repeating the exercise, with a new list reflecting the emerging trends in global thought.

How did we decide who should be on this list? The criteria are relatively simple. Candidates have to be living, and still active in public life. They have to have shown distinction in their particular field as well as an ability to influence debate across borders.

Here's how to vote:

1) Choose your five top intellectuals in the ballot below by clicking on an individual's name. (If you are unfamiliar with any of our picks, just check out their bios.) To undo a pick, simply click the box again.

2) Nominate an extra candidate. Who have we unjustly excluded? Click the "Nominate an extra candidate" option at the bottom of the ballot, and let us know who we missed.

3) Submit your votes.

If you have any difficulty, please email us at intellectuals@prospect-magazine.co.uk

Voting closes Thursday 15th May. Results will be announced in the July issue of Prospect, and online on Monday 23rd June. You can challenge our selection on our blog First Drafts.
