Science stripped from a governing moral order was not the deliverer it was thought to be. Something was wrong with man . What some men designed for good, other men intended for evil. Nuclear energy can be used to light cities or reduce them to ashes. Chemistry can improve nutrition or make nerve gas.
Biology can make vaccinations or germ weapons.
Science furnishes neither truth nor moral values. The secular religionists had put their trust in technology and the Darwinian worldview of promised evolutionary advancement. Survival of the fittest had become the new ethical standard. The American industrialist Andrew Carnegie embraced the social implications of Darwin's theories and applied them to the world of business. That light came in as a flood and all was clear.
