What a superb writer he is, and he seems to get better and better.” - Richard Dawkins, author of The Selfish Gene Nature via Nurture is a scrupulous and charming look at our modern understanding of genes and experience.” - Oliver Sacks ”'Bracingly intelligent, lucid, balanced - witty, too. ”'Lucidly explains the most recent discoveries on what makes us what we are, and how we should think about these discoveries as we ponder who we want to be…A treat, written with insight, wisdom, and style.” - Steven Pinker, author of The Blank Slate These times need a book like this.” - Ian McEwan And yet this plasticity, this elegant mutuality, seems crucial if our new understanding of human nature is to inform public policy. ”'Nature via Nurture sets the modern terms for an ancient debate, and at the same time delivers a superb tutorial on contemporary genetics the feedback loop that embraces genes and environment is generally not well understood. The Rational Optimist will do for economics what Genome did for genomics and will show that the answer to our problems, imagined or real, is to keep on doing what we’ve been doing for 10,000 years – to keep on changing. In this original, optimistic book, Matt Ridley puts forward his surprisingly simple answer to how humans progress, arguing that we progress when we trade and we only really trade productively when we trust each other. Yet, bizarrely, however much things improve from the way they were before, people still cling to the belief that the future will be nothing but disastrous. The availability of almost everything a person could want or need has been going erratically upwards for 10,000 years and has rapidly accelerated over the last 200 years: calories vitamins clean water machines privacy the means to travel faster than we can run, and the ability to communicate over longer distances than we can shout. Today there are more than 6 billion, 99 per cent of whom are better fed, better sheltered, better entertained and better protected against disease than their Stone Age ancestors. Over 10,000 years ago there were fewer than 10 million people on the planet. In The Rational Optimist Ridley offers a counterblast to the prevailing pessimism of our age, and proves, however much we like to think to the contrary, that things are getting better.

Matt Ridley, acclaimed author of the classics Genome and Nature via Nurture, turns from investigating human nature to investigating human progress.
