An element of risk was necessary if scientific progress was to be made, despite concerns about "meddling with nature", A C Grayling, said.
 
The philosopher and author told the annual Ways with Words literary festival at Dartington Hall, Devon, that no one should be afraid of "trying to get the benefits of certain possibilities." He said: "Meddling with nature is a genuine concern, for example with genetically modified crops, but it is also the case that human intelligence is a product of nature.

"We are ourselves a product of nature. The things we do to ourselves and to our environment is a natural outcome of the fact that we are creative, intelligent and exploratory. "We should not be afraid of trying to get the benefits of certain possibilities. A certain kind of courage or risk taking is worthwhile."

He said the creation of human sperm using stem cells could help infertile men who would really love to be fathers."
Prof Grayling was the opening speaker at the nine-day festival which is sponsored by The Daily Telegraph. Other speakers include Charles Moore, the Daily Telegraph columnist and former editor, Andrew Motion, the Poet Laureate, and Roy Hattersley, the former Labour minister.
