From the beginning of the 20th century through the 1960's was an amazing era in the history of the world. Men dared to do great things. There were inventors: Two brothers named Wright built a rickety contraption of wood and cloth and flew through the air. There were engineers: Roosevelt and Goethals cut a canal through a continent at Panama, perhaps the largest building project in history. There were explorers: Scott and Amundsen braved the polar regions to fill in the last blank spaces on the map. Armstrong and Aldrin and others actually walked on the moon.
Sometimes they failed, of course. Many gave their lives. Sometimes the failures were spectacular and disastrous. The Titanic and the Hindenberg come to mind. But when they failed, they failed while daring greatly.
In the 1970s, men lost the courage to fight for freedom or to travel to other planets. By the 1990's, they had lost the courage to eat a meal without first carefully checking if it might not contain barely-measurable amounts of theoretically dangerous chemicals.
They still failed, of course. No one can achieve 100% safety. And when they failed, they failed while cowering in a corner whining about the unfairness of it all and begging for help.
