THE British Science Guild, the annual meeting of which was held on April 29, occupies a peculiar position among kindred societies. We have societies concerned with the promotion of science in general—notably the Royal Society—and of particular sciences such as chemistry, physics, geology, botany and zoology, and their numerous progeny—physical chemistry, biochemistry, and the rest. There are other societies—the Society of Chemical Industry is a good example—which devote themselves to the application of particular sciences to industry. The British Science Guild, founded by Sir Norman Lockyer in 1905 “to promote the application of scientific methods and results to social problems and public affairs,” is not a scientific society, nor an institute of industry, nor an educational association. It is a national organisation, the chief purpose of which is to reconcile the interests of science industry, and education, and to co-ordinate their activities. Sir William Bragg, in a recent broadcast talk explaining the work of the Guild, said: “In originality of scientific work, mechanical ingenuity and operative skill, our race is in the forefront.” This claim will be confirmed by the most cursory inspection of our national roll of men of science and invention. But there is something lacking, he suggests, and that is “a spirit of unity among all classes through the alliance of science, invention and labour working as a single force for national development and common welfare.” To this “spirit of unity” the nation, beset by its war-heritage of financial and industrial problems, will have to pay increasing homage if it is to maintain its leading position, achieved in large measure through its “scientific work, mechanical ingenuity, and operative skill.”
