The Rational Optimist by Matt Ridley Introduction In The Rational Optimist, renowned science writer Matt Ridley offers a powerful and counter-intuitive argument for optimism in the modern world. Through a sweeping history of humanity, Ridley shows how our unique ability to trade, specialize and share ideas has consistently driven progress, raised living standards and solved seemingly insurmountable problems. Ridley argues that when ideas meet and mix, they generate cumulative innovation, creating a richer, healthier and safer world. This summary explores his rational perspective on human history and why we have every reason to look forward to the future with hope.
Chapter 1 We are lucky to live in the modern world Life in the past was violent, arduous and short-lived. Today, when we read the news or browse online, we are confronted by numerous experts expounding on the dangers of the modern world and telling us to fear coming calamities. They contend that new diseases are unstoppable, famine will kill billions, overpopulation will ruin the environment and climate change will destroy the planet. Many of these experts argue that the solution to escaping these impending modern catastrophes lies in the past.
They suggest that because past societies lacked such modern problems, they were simpler and more idyllic. Some even argue that our own society should be modeled on those of the past. In reality, this rose-tinted view of history is far from the truth. The past was a truly dreadful time to live.
Right up until the Industrial Revolution, life was dominated by violence, famine, illness and early death. In early hunter-gatherer societies, where neighboring tribes fought for scarce resources, violence was often imminent. Many burial sites from the era show evidence of entire communities massacred by blows to the head or struck by arrows, spears and darts. Famine and illness were also constant threats to early societies.
Communities lacked adequate agricultural technologies, so they were especially susceptible to drought, crop failures and famines, which often led to malnutrition, decreased fertility and starvation. Disease was rife and the prevalence of aggressive bacteria like gangrene and tetanus made every wound potentially deadly. There's just no comparison to modern times. Today, the living standard of human beings is at an all-time high.
Since 1800, the global population has grown by a factor of six, life expectancy has doubled and real income has increased almost tenfold. Today, most of us live incredibly safe and healthy lives.
Chapter 2: The discovery of cooking
The discovery of cooking facilitated the first innovation networks, allowing knowledge to flow between civilizations. Humanity hasn't always possessed a natural ability to trade and interact. Early humans existed in small familial or tribal groups and did not produce many significant advances in technology. That changed, however, with the discovery of cooking.
Cooking was the first step in our cultural evolution. More calories can be obtained from a cooked food than a raw food, and it requires less chewing. As a result of cooking, more nutritious food could be shared by more people in less time. Cooking also led to the early specialization of labor.
Women collected grains and staple carbohydrates, while men hunted larger animals for protein. This, along with the extra nutrition gained from cooking, created a surplus of food, which led to the beginning of trade. As trust between strangers slowly increased, we began to trade things other than food. This trading developed into the first innovation networks 160,000 years ago.
For the first time, people had access to different communities' cultural traditions, raw materials and technologies. They could also share knowledge, even between distant communities. Archaeological sites from the era show evidence of similar tools and ornamental shells, appearing in sites hundreds or thousands of miles apart. This cultural evolution was vital to human development.
The welfare of humanity skyrocketed as we benefited from the collective knowledge of our trading partners. In fact, cultures that lacked successful trading networks are shown to have had a smaller collective knowledge and became deficient in technologies. For example, 10,000 years ago, the Tasmanians were cut off from the mainland by rising seas, and consequently their use of technology deteriorated. They lost the ability to make cold weather clothing, fish hooks, or barbed spears.
Their isolation meant they did not advance along with those on the mainland.
