Right, imagine that you having 10 people around for dinner. Who woud you choose if you had a time machine like Bill and Ted's. Don't post an answer immediately, as this needs some thought. You couldn't have too many people form one discipline or field as the conversation would only be about that subject. What would you want to talk about? Who would stimulate new ways of thinking by another, who would you like to meet?

One proviso, they all have to be real people who actually existed.

Here goes, a starter, in no particular order.

Gautama, the Buddha
Hannibal the Great
Leonardo da Vinci
Genghis Khan
Jesus Christ
Pharoah Akhetanon
Charles Darwin
Joseph Stalin
Nelson Mandela
Raleights (or Violent Demise as long as he's not vegetarian)

I would also ask Hitler, but only for coffee as I would nto want him around while I was eating.
