The Rational Optimist: How Prosperity Evolves by Matt Ridley

5.0

Pessimists get all the media coverage; optimists are poo-pooed for their naivete. Nevertheless, Matt Ridley puts together a good argument that in general, conditions in the world are improving. Not everywhere, of course; but in general, living conditions are improving, there is less violence, innovation is accelerating, and the dire events predicted by doomsayers are not coming true.

Free trade, cheap energy, and specialization are the things that help grow civilizations. Science is not the cause of, but a by-product of innovation. Innovation is the result of new ideas "having sex" with each other. These and many other interesting concepts are explained in this book, and make it very enjoyable.
