...I stayed up all night reading [The Structure of Scientific Revolutions] with demented avidity to the final page, my empirical understanding of the world undone by Kuhn's argument that scientific theories are in essence evolutionarily selected stories, that is fictions that best fit the available facts—until the discovery of new facts forces a paradigm shift to a different and better fiction. More than that, he argues that scientist who embrace a new paradigm at an early stage—before sufficient evidence has been amassed to trigger a scientific revolution—do so not out of a sober consideration of the available facts, or at least not only that, but also with a subjective, irrational, from-the-gut leap of faith.
