The Structure of Scientific RevolutionsThe 1962 book, Structure of Scientific Revolutions, by Thomas Kuhn, was an extremely influential book. It popularized the terms paradigm and "paradigm shift", and gave a leftist view of how science works that fascinated philosophers and other academic non-scientists.
Most of the book was not controversial. What made the book radical was its view that there is no such thing as scientific progress, and that science is actually an irrational process that jumps from paradigm to paradigm without really getting any closer to the truth. The view is popular among relativists who like to deny that there is any absolute truth.
