"Perhaps we would have forestalled [human] extinction if Louis Pasteur had abandoned his studies on the germ theory. What about the plant pathologists who scorned centuries of superstitions and identified the fungi responsible for cereal diseases? They made it possible to combat the rusts and smuts that wasted crops and allowed modern agriculture to feed us in our billions. Science is so central to modern civilization that we will not willingly retreat from the continuing exploration and manipulation of nature."
