Is there really a scientific method? Some scientists call it a myth
Schoolbooks present it as a neat recipe: observe, hypothesise, test, conclude. Yet in 1975 Paul Feyerabend published Against Method, denying that science follows any universal rules, and in 2013 physicist Lee Smolin wrote an essay bluntly titled There Is No Scientific Method. The argument over how discovery actually works has never settled.
At its core the idea is simple. You propose an explanation, work out what should happen if it is right, and then check with experiments or observations. The crucial requirement is falsifiability: a hypothesis must allow some possible result that would contradict it, or it cannot be meaningfully tested. Results feed back into new questions, and other scientists retest, so the process loops rather than marching in a straight line. Many discoveries have skipped steps or relied on luck.
The roots are old and scattered. William of Ockham, Avicenna, Aristotle, Roger Bacon, Epicurus, Al-Biruni, the Stoics and Alhazen all voiced versions of empirical thinking. Alhacen's Book of Optics, from 1027, and Galileo's Two New Sciences, from 1638, used experiments to overturn accepted theory. During the Scientific Revolution Francis Bacon championed experiment, Descartes argued for reason and Isaac Newton set out four guiding principles.
Oddly, the phrase itself only arrived in the 19th century, as science became an institution with words like scientist and pseudoscience to police its borders. John Dewey's 1910 book How We Think helped popularise it in textbooks, though nobody agreed what it meant. By the 1960s and 1970s Thomas Kuhn and Feyerabend were recasting science as a patchwork of local practices. Karl Popper disagreed, and later philosophers noted that even Feyerabend quietly accepted some rules. Historian Daniel Thurs, in a 2015 collection, called the method a myth, or at best an idealisation.
Progress often builds rather than demolishes. When Einstein produced his theories of relativity he did not throw out Newton; strip away the very massive, the very light and the very fast, which Newton could never observe, and Newton's equations are what remain. Benjamin Franklin correctly guessed that St Elmo's fire was electrical, but proving it took a long run of experiments. Picking a good question, it turns out, can be the hardest step.
