Wisely used, science can make for greater human happiness, (u. s. forest service) satisfactory environment are almost im- mediate; that is, they are produced within one generation. Consider this problem by doing Exercise i i. Many scientists are convinced that the greatest hope of improving human beings lies in improving the environment rather than in tr>nng to breed better men. The improvement of the human race through improvement of the environment is known as euthenics, in contrast to eu- genics. Improvement of mankind through sci- ence. Many of the improvements made by man in his environment have come about within recent years. Rapid prog- ress came when man began to apply the scientific method more generally. Thus he learned to understand something of his environment and of himself. He made many discoveries and inventions that gave him better food, that protected him against diseases, and that brought him into closer touch with other men. He also made countless discoveries and inventions which brought more leisure and more comfort in life. Science has given us much more than the benefits just listed. It has given us greater security; it has taught us to banish certain fears and to conquer superstition to a great extent. Do Exercise 12. And it has shown us, if we will but learn, how we can all use the methods of science; how we must train ourselves to seek out all the facts, to face them squarely, to suspend judgment while we weigh the facts carefully, to reason accurately, and to report truth- fully. While we do this we must learn how to work with others, for progress is greatest when men work together, shar- ing information freelv, as scientists Please note that these images a
