His books – including The Evolution of Everything, The Red Queen, The Origins of Virtue, The Agile Gene, and The Rational Optimist – have sold over a million copies and have been translated into thirty languages. Ridley infuses his scholarly approach to the study of biology, the climate and economics with a hefty dose of panache, wit and humor. His enthusiasm for his subjects is contagious, and his presentations – whether you agree with him or not – are always stimulating, thought-provoking and entertaining.
