In A Culture of Growth: The Origins of the Modern Economy Joel Mokyr has located the source of the industrial revolution in the culture of the Enlightenment. The Enlightenment prioritized the idea of human progress. As a result, people began to think constantly of finding material in the world to make new technologies for human betterment. The Enlightenment also replaced more scholastic modes of thought with scientific method. As a result, people began intensively to test both new theories to see if they explained the world and new mechanisms to see how they would move the world. As a consequence, the Western economy began to grow at a rate never before seen in history.
A Culture for Growth is a wonderful book to which I cannot do justice in a short post. Mokyr is in equal measures a great intellectual historian and a great economist. He sees the cultural change of the Enlightenment as transforming the incentives for economic and intellectual activity. It removed taboos that impeded progress and created a market where the best new ideas rapidly gained a large market share of elite approval. This book is welcome for many reasons, but not least because it is a blow to tedious, tendentious, and false political correctness about the roots our our prosperity. The Enlightenment was indeed key to material progress that helped the least well off, first in the West and now more broadly throughout the globe. And yes, it was the product almost entirely of dead white men, and relatively wealthy ones at that.
Although this is not his focus, I believe Mokyr’s book also establishes the crucial link between the levers of the Enlightenment and the growth of liberty.
