The changes of mind that gave philosophers and scientists new insights
James Randerson, science correspondent
They are the intellectual elite, the brains the rest of us rely on to make sense of the universe and answer the big questions. But in a refreshing show of new year humility, the world's best thinkers have admitted that from time to time even they are forced to change their minds.
When tackling subjects as diverse as human evolution, the laws of physics and sexual politics, scientists and philosophers, includingSteven Pinker , Daniel Dennett , Paul Davies  and Richard Wrangham , all confessed yesterday to a change of heart.
The display of scientific modesty was brought about by the annual new year's question posed by the website edge.org, which drew responses from more than 120 of the world's greatest thinkers.
