Now Science has not only this in common with Socialism that it has grown out of men's courageous confidence in the superiority of order to muddle, but these two great processes of human thought are further in sympathy in the demand they make upon men to become less egotistical and isolated. The main difference of modern scientific research from that of the middle ages, the secret of its immense successes, lies in its collective character, in the fact that every fruitful experiment is published, every new discovery of relationships explained. In a sense scientific research is a triumph over natural instinct, over that mean instinct that makes men secretive, that makes a man keep knowledge to himself and use it slyly to his own advantage. The training of a scientific man is a training in what an illiterate lout would despise as a weakness; it is a training in blabbing, in blurting things out, in telling just as plainly as possible and as soon as possible what it is he has found. To "keep shut" and bright-eyed and to score advantages, that is the wisdom of the common stuff of humanity still. To science it is a crime. The noble practice of that noble profession medicine, for example, is to condemn as a quack and a rascal every man who uses secret remedies. And it is one of the most encouraging things for all who speculate upon human possibility to consider the multitude of men in the last three centuries who have been content to live laborious, unprofitable, and for the most part quite undistinguished lives in the service of knowledge that has transformed the world. Some names indeed stand out by virtue of gigantic or significant achievement, such names as Bacon, Newton, Volta, Darwin, Faraday, Joule; but these are but the culminating peaks of a nearly limitless Oberland of devoted toiling men, men one could list by the thousand. The rest have had the smallest meed of fame, small reward, much toil, much abandonment, of pleasure for their lot. One thing ennobles them all in common--their conquest over the meanness of concealment, their systematic application of energy to other than personal ends!
