"Today, we live in a time when science and economics have produced so much wealth and so many marvelous inventions it is hard to imagine what will come next. As we enjoy the benefits of our age, however, we must wonder how these material achievements are affecting the moral behavior of the world's people. The world has become so complex, individuals are now more able than ever to select their own realities, and to make decisions based on personal feelings or personal assessments of what is true and false."
