The Commens Dictionary
Quote from ‘From Comte to Benjamin Kidd’
Science is not a fixed, unchangeable body of propositions. After a thousand years the general face of science may be modified past recognition. Scientific hypotheses are questions put to nature. In the game of twenty questions no skilful player begins by guessing what he thinks most likely. He seeks to fix one feature at a time. Scientific research is a much more intricate business, and various considerations go to determining what is the best hypothesis to try.
