Hominids evolved and developed for millions of years prior to the arrival of Homo sapiens on the Earth. This evolution was slow. The development of a new skill or tool often took thousands of years. With the arrival of Homo sapiens, this all changed. The speed of advancements increased dramatically. Instead of thousands of years, great progress was made in hundreds or even dozens of years.
I believe that to meet the challenge of the next century, human beings will have to develop a greater sense of universal responsibility. Each of us must learn to work not just for his or her own self, family or nation, but for the benefit of all mankind.
"In God We Trust" has appeared on most U.S. coins since about 1864.
