Bo Winegard and Ben Winegard in Quillette:
In science, the jury is always out. This is because science is a methodological approach to the world, not a set of inflexible principles or a catalog of indisputable facts. Truth is always provisional. Science does not hold something to be incontrovertibly true. It says, “This appears to be true according to the best available theory and evidence.” On science, the jury long ago returned a verdict: it is awesome. It has conquered deadly diseases and eradicated oppressive superstitions. It has increased human flourishing and extended life expectancies. It has put humans on the moon and many fathoms under the ocean’s surface. It has uncovered the forces that guide the crudest motions of matter and those that govern the most exquisite processes of life. In short, it has vastly improved human existence while dramatically increasing our knowledge of the universe.
Despite all this, skeptical philosophers and pundits continue to forward arguments against scientific “arrogance”—or against what they see as science’s hubristic attempt to crowd out other forms of understanding and discourse. In recent years, these arguments have focused on what is called “scientism,” a malleable term that is vaguely pejorative. (It’s worth noting that this term can be used clearly and effectively, as in Susan Haack’s excellent article, for instance.)
