“They have to leave their mark. They can't just watch. They can't just appreciate. They can't just fit into the natural order. They have to make something unnatural happen. That is the scientist's job, and now we have whole societies that try to be scientific... We've had four hundred years of modern science, and we ought to know by now what it's good for, and what it's not good for. It's time for a change.”
