Biologists study life in its various physical forms, while philosophers of biology seek answers to questions about the nature, purpose, and impact of this research. What permits us to distinguish between living and nonliving things even though both are made of the same minerals? Is the complex structure of organisms proof that a creative force is working its will in the physical universe, or are existing life-forms the random result of an evolutionary process working itself out over eons of time? What moral and social questions arise regarding modern advances in biotechnology? What is more relevant to human nature: genetics or sociocultural influences? Is Darwinism the death-knell of God? These are just some of the vital questions addressed by a distinguished group of philosophers and scientists which includes: Aristotle, Francisco J. Ayala, , Michael Benton, Tom Bethell, Joe Cain, David Castle, Charles Darwin, Richard Dawkins, Michael Denton, A.G.N. Flew, Stephen Jay Gould, J.B.S. Haldane, John F. Haught, D. W. E. Hone, James W. Kirchner, James Lovelock, Jane Maienschein, Ernst Mayr, Gregory M. Mikkelson, Leslie Orgal, William Paley, the Prince of Wales, Christopher Pynes, Richard A. Richards, Mark Ridley, Holmes Rolston III, Michael Ruse, Lee Silver, Elliott Sober, Kim Sterelny, Derek Turner, and Edward O. Wilson. This second edition contains material on design without selection, testing macroevolutionary claims, recent biotechnological issues, key ecological concerns, the Gaia hypothesis, genetically modified foods, and the so-called intelligent design movement

Hopes of applying the findings and speculations of evolutionary theorizing to the problems of ethics have yielded a program with a bad reputation. At the level of norms – substantival ethics – it has been a platform for some of the more grotesque socio-politico-economic suggestions of our times. At the level of justification – metaethics – it has opened the way to some of the more blatant fallacies in the undergraduate textbook. Recently, however, a number of people, philosophers and biologists, have sensed that a more adequate evolutionary ethics might be possible. United in the conviction that it simply has to matter that we humans are modified monkeys rather than the creation of a Good God, in His image, on the Sixth Day, they argue that recent developments in evolutionary biology, especially those dealing with the genetic basis of social behavior, open the way to a satisfactory biological understanding of morality

(1) For much of this century, moral philosophy has been constrained by the supposed absolute gap between is andought, and the consequent belief that the facts of life cannot of themselves yield an ethical blueprint for future action. For this reason, ethics has sustained an eerie existence largely apart from science. Its most respected interpreters still believe that reasoning about right and wrong can be successful without a knowledge of the brain, the human organ where all the decisions about right and wrong are made. Ethical premises are typically treated in the manner of mathematical propositions: directives supposedly independent of human evolution, with a claim to ideal, eternal truth.

The section on the Argument from Design in collections of readings in the philosophy of religion usually begins with an expository selection drawn from Archdeacon William Paley’s Natural Theology, and follows with a critical selection drawn from David Hume’s Dialogues Concerning Natural Religion. Only from the footnotes does the student learn that Hume’s Dialogues was published over twenty years before Paley’s Natural Theology. Probably the student will feel that Hume’s devastating critique of the Argument must strike every reasonable person with equal force, and so he will conclude that Paley must have been an archetypal intellectual conservative—a man whose ideas were dead and fossilized long before he put pen to paper. In fact, historically, the very opposite was the case. Although few could deny Hume’s towering intellect—“God’s greatest gift to the infidel” one fellow Scot grudgingly called him—Hume failed entirely to break the hold that the Argument from Design had on people’s imaginations. As many of us feel about Descartes’s arguments from illusion, people “knew” that somehow there must be a flaw in Hume’s argumentation, for, in the words of the anatomist Richard Owen, organic characters like the hand, the foot, and the eye, bear “irrefragable evidence of creative foresight.” Far from being outdated before it appeared, Paley’s book, in which he drew lucidly upon the most recent findings in natural science, rapidly became the standard work on the Argument from Design. It was, for instance, considered essential reading in any young man’s university education.

In this paper I shall discuss the concept of reduction—ontological, methodological, and epistemological or theoretical—in the biological sciences, with special emphasis on genetics and evolutionary biology. I suggest that perhaps, because the biological world has a form different from the non-biological world, it is appropriate to think of terms or metaphors different from those we would use when trying to understand the inorganic world. As such, the attempt to show that the biological is simply a deductive consequence of the physicochemical is doomed to failure. The philosophical complexity of reductionism on the one hand and its potential for advancing the study of biology on the other thus requires continuing the ongoing dialogue between philosophers and biologists.

The homologies of process within morphogenetic fields provide some of the best evidence for evolution—just as skeletal and organ homologies did earlier. Thus, the evidence for evolution is better than ever. The role of natural selection in evolution, how–ever, is seen to play less an important role. It is merely a filter for unsuccessful morphologies generated by development. Population genetics is destined to change if it is not to become as irrelevant to evolution as Newtonian mechanics is to contempo–rary physics.

Drawing on work of the past decade, this volume brings together articles from the philosophy, history, and sociology of science, and many other branches of the biological sciences. The volume delves into the latest theoretical controversies as well as burning questions of contemporary social importance. The issues considered include the nature of evolutionary theory, biology and ethics, the challenge from religion, and the social implications of biology today (in particular the Human Genome Project).

A brief historical overview shows the main Christian claims aboutmorality and proper conduct, looking at questions about both prescriptions and foundations . Jesus did not leave a fully articulated ethical system, and hence it fell to his followers to tease out such a system from hism sayings and actions. Particularly important for Catholic thinking has been the natural law theory of St. Thomas Aquinas. Particularly important for Protestant thinking have been the directives of the Gospel stories, although different branches of Protestantism emphasize different parts of Christ's teachings. Foundationally important for all Christians is God's will or desire, and it is necessary to show that this does not commit the believer to potentially capricious divine directives

The question of the levels at which natural selection can be said to operate is much discussed by biologists today and is a key factor in the recent controversy about sociobiology. It is shown that this problem is one to which Charles Darwin addressed himself at some length. It is argued that apart from some slight equivocation over man, Darwin opted firmly for hypotheses supposing selection always to work at the level of the individual rather than the group. However, natural selection's co-discoverer, Alfred Russel Wallace, endorsed group selection hypotheses

Several years ago, I was asked to participate in a forum on evolution. Flattered, I accepted, only discovering later that I was to participate in a “debate”, involving me and a scientist squaring off against two Creationists, Henry M. Morris and Duane T. Gish. The topic for discussion was which doctrine has the greatest scientific merit: organic evolution through natural processes set against the background of a very old earth, or special instantaneous appearance of all organisms, about 6000 years ago, followed shortly thereafter by a world-wide flood? I very much doubt that many minds were changed on that particular evening—the bleachers were packed with ardent Baptists bussed in from all over Wisconsin and Illinois. The 10 or so in the audience who believed in evolution went on believing in evolution. The 5000 in the audience who took the early chapters of Genesis absolutely literally went on taking the early chapters of Genesis absolutely literally. But, people's time was far from wasted. Morris and Gish got the attention they crave. Their supporters were thrilled by the sight of heretics publicly proclaiming doctrines for which they would surely earn eternal damnation. And, I learnt what a hollow sham modern day Creationism really is: crude, dogmatic, Biblical literalism, masquerading as genuine science, in order to avoid the strictures of the first amendment to the U.S. Constitution, which bars the teaching of religion in schools.
