The Enlightenment
The development of modern science in the late 18th century went hand in hand with the rise of modern industrial capitalism. Its potteries, mines, steam engines, mechanization, and science itself, were all done by private enterprise. The role of government was to enforce patents and maintain a healthy legal and commercial environment.
Nowadays most scientists are paid by the government. What passes for science has largely become taxpayer-funded Environmentalism. Environmentalism has taken over much of science.
Scientists discover, understand and inform.
Environmentalists preach.
