Were these boys in their right minds? Here were two boys with good intellect, one eighteen and one nineteen. They had all the prospects that life could hold out for any of the young; one a graduate of Chicago and another of Ann Arbor; one who had passed his examination for the Harvard Law School and was about to take a trip in Europe,--another who had passed at Ann Arbor, the youngest in his class, with three thousand dollars in the bank. Boys who never knew what it was to want a dollar; boys who could reach any position that was to boys of that kind to reach; boys of distinguished and honorable families, families of wealth and position, with all the world before them. And they gave it all up for nothing, for nothing! They took a little companion of one of them, on a crowded street, and killed him, for nothing, and sacrificed everything that could be of value in human life upon the crazy scheme of a couple of immature lads.Now, your Honor, you have been a boy; I have been a boy. And we have known other boys. The best way to understand somebody else is to put yourself in his place.Is it within the realm of your imagination that a boy who was right, with all the prospects of life before him, who could choose what he wanted, without the slightest reason in the world would lure a young companion to his death, and take his place in the shadow of the gallows?...No one who has the process of reasoning could doubt that a boy who would do that is not right.How insane they are I care not, whether medically or legally. They did not reason; they could not reason; they committed the most foolish, most unprovoked, most purposeless, most causeless act that any two boys ever committed, and they put themselves where the rope is dangling above their heads....Why did they kill little Bobby Franks?Not for money, not for spite; not for hate. They killed him as they might kill a spider or a fly, for the experience. They killed him because they were made that way. Because somewhere in the infinite processes that go to the making up of the boy or the man something slipped, and those unfortunate lads sit here hated, despised, outcasts, with the community shouting for their blood.. . . I know, Your Honor, that every atom of life in all this universe is bound up together. I know that a pebble cannot be thrown into the ocean without disturbing every drop of water in the sea. I know that every life is inextricably mixed and woven with every other life. I know that every influence, conscious and unconscious, acts and reacts on every living organism, and that no one can fix the blame. I know that all life is a series of infinite chances, which sometimes result one way and sometimes another. I have not the infinite wisdom that can fathom it, neither has any other human brain

In every remote corner of the world there are people like Carl Jones and Don Merton who have devoted their lives to saving threatened species. Very often, their determination is all that stands between an endangered species and extinction.But why do they bother? Does it really matter if the Yangtze river dolphin, or the kakapo, or the northern white rhino, or any other species live on only in scientists' notebooks?Well, yes, it does. Every animal and plant is an integral part of its environment: even Komodo dragons have a major role to play in maintaining the ecological stability of their delicate island homes. If they disappear, so could many other species. And conservation is very much in tune with our survival. Animals and plants provide us with life-saving drugs and food, they pollinate crops and provide important ingredients or many industrial processes. Ironically, it is often not the big and beautiful creatures, but the ugly and less dramatic ones, that we need most.Even so, the loss of a few species may seem irrelevant compared to major environmental problems such as global warming or the destruction of the ozone layer. But while nature has considerable resilience, there is a limit to how far that resilience can be stretched. No one knows how close to the limit we are getting. The darker it gets, the faster we're driving.There is one last reason for caring, and I believe that no other is necessary. It is certainly the reason why so many people have devoted their lives to protecting the likes of rhinos, parakeets, kakapos, and dolphins. And it is simply this: the world would be a poorer, darker, lonelier place without them.

Thus, by science I mean, first of all, a worldview giving primacy to reason and observation and a methodology aimed at acquiring accurate knowledge of the natural and social world. This methodology is characterized, above all else, by the critical spirit: namely, the commitment to the incessant testing of assertions through observations and/or experiments — the more stringent the tests, the better — and to revising or discarding those theories that fail the test. One corollary of the critical spirit is fallibilism: namely, the understanding that all our empirical knowledge is tentative, incomplete and open to revision in the light of new evidence or cogent new arguments (though, of course, the most well-established aspects of scientific knowledge are unlikely to be discarded entirely).. . . I stress that my use of the term 'science' is not limited to the natural sciences, but includes investigations aimed at acquiring accurate knowledge of factual matters relating to any aspect of the world by using rational empirical methods analogous to those employed in the natural sciences. (Please note the limitation to questions of fact. I intentionally exclude from my purview questions of ethics, aesthetics, ultimate purpose, and so forth.) Thus, 'science' (as I use the term) is routinely practiced not only by physicists, chemists and biologists, but also by historians, detectives, plumbers and indeed all human beings in (some aspects of) our daily lives. (Of course, the fact that we all practice science from time to time does not mean that we all practice it equally well, or that we practice it equally well in all areas of our lives.)
