First published in 1938, Science for the Citizen is partly written for the large and growing number ofintelligent adults who realize that the Impact of Science on Society is now thefocus of genuinely constructive social effort. It is also written for the largeand growing number of adolescents, who realize that they will be the firstvictims of tie new destructive powers of science misapplied. Since it is thefirst British handbook to Scientific Humanism, it has, inevitably, the glaringfaults of any new thing. Education segregates the scientific specialist fromthose who study problems of government and social welfare. So, like anyoneelse who in this generation might have attempted a task so ambitious, Ihave had to re-educate myself in the process of writing it.
