Freeman Dyson on Biological and Cultural Evolution

"Our double task is now to preserve and foster both biological evolution as Nature designed it and cultural evolution as we invented it, trying to achieve the benefits of both, and exercising a wise restraint to limit the damage when they come into conflict," writes Freeman Dyson, Professor Emeritus in the School of Natural Sciences, in his Edge essay "Biological and Cultural Evolution: Six Characters in Search of an Author."
