This book traces the history of life-concepts, with a focus on the vegetable souls of Aristotle, investigating how they were interpreted and eventually replaced by evolutionary biology. Philosophers have long struggled with the relationship between physics, physiology, and psychology, asking questions of organization, purpose, and agency. For two millennia, the vegetable soul, nutrition, and reproduction were commonly used to understand basic life and connect it to “higher” animal and vegetable life. Cartesian dualism and mechanism destroyed this bridge and left biology without an organizing principle until Darwin. Modern biology parallels Aristotelian vegetable life-concepts, but remains incompatible with the animal, rational, subjective, and spiritual life-concepts that developed through the centuries. Recent discoveries call for a second look at Aristotle’s ideas – though not their medieval descendants. Life remains an active, chemical process whose cause, identity, and purpose is self-perpetuation.

Darwin's theory of evolution remains controversial, even though most scientists, philosophers, and even theologians accept it, in some form, as an explanation for the variety of organisms. The controversy erupts when the theory is used to try to explain everything, including every aspect of human life, and to deny the role of a Creator or a purpose to life. The overreaching of many scientists into matters beyond the self-imposed limits of scientific method is perhaps explained in part by the loss of two important ideas in modern thinking--final causality or purpose, and formal causality. Scientists understandably bracket the idea out of their scientific thinking because they seek explanations on the level of material and efficient causes only. Yet many of them wrongly conclude from their selective study of the world that final and formal causes do not exist at all and that they have no place in the rational study of life. Likewise, many erroneously assume that philosophy cannot draw upon scientific findings, in light of final and formal causality, to better understand the world and man. The great philosopher and historian of philosophy, Etienne Gilson, sets out to show that final causality or purposiveness and formal causality are principles for those who think hard and carefully about the world, including the world of biology. Gilson insists that a completely rational understanding of organisms and biological systems requires the philosophical notion of teleology, the idea that certain kinds of things exist and have ends or purposes the fulfillment of which are linked to their natures--in other words, formal and final causes. His approach relies on philosophical reflection on the facts of science, not upon theology or an appeal to religious authorities such as the Church or the Bible.

In a book that is both groundbreaking and accessible, Daniel C. Dennett, whom Chet Raymo of The Boston Globe calls "one of the most provocative thinkers on the planet," focuses his unerringly logical mind on the theory of natural selection, showing how Darwin's great idea transforms and illuminates our traditional view of humanity's place in the universe. Dennett vividly describes the theory itself and then extends Darwin's vision with impeccable arguments to their often surprising conclusions, challenging the views of some of the most famous scientists of our day.

For evolutionary biologists, the concept of chance has always played a significant role in the formation of evolutionary theory. As far back as Greek antiquity, chance and "luck" were key factors in understanding the natural world. Chance is not just an important concept; it is an entire way of thinking about nature. And as Curtis Johnson shows, it is also one of the key ideas that separates Charles Darwin from other systematic biologists of his time. Studying the concept of chance in Darwin's writing reveals core ideas in his theory of evolution, as well as his reflections on design, purpose, and randomness in nature's progression over the course of history. In Darwin's Dice: The Idea of Chance in the Thought of Charles Darwin, Curtis Johnson examines Darwin's early notebooks, his collected correspondence (now in 19 volumes), and most of his published writing to trace the evolution of his ideas about chance in evolution. This proved to be one of Darwin's most controversial ideas among his reading public, so much so that it drew hostile reactions even from Darwin's scientific friends, not to mention the more general reader. The firestorm of criticism forced Darwin to forge a retreat, not in terms of removing chance from his theory--his commitment to it was unshakable--but in terms of how he chose to present his theory. Briefly, by changing his wording and by introducing metaphors and images (the stone-house metaphor, the evolution of giraffes, and others), Darwin succeeded in making his ideas seem less threatening than before without actually changing his views. Randomness remained a focal point for Darwin throughout his life. Through the lens of randomness, Johnson reveals implications of Darwin's views for religion, free will, and moral theory. Darwin's Dice presents a new way to look at Darwinist thought and the writings of Charles Darwin.

A fresh account of Charles Darwin’s rich personal and professional lives, well beyond On the Origin of Species. In 1859 Charles Darwin published On the Origin of Species. With this bedrock of biology books, Darwin carved a new origin-story for all life: evolution rather than creation. But this single book is not the whole story. In this new biography, J. David Archibald describes and analyzes Darwin’s prodigious body of work and complex relationships with colleagues, as well as his equally productive home life—he lived with his wife and seven surviving children in the bustling environs of Down House, south of London. There, among his family and friends, Darwin continued to experiment and write many more books on orchids, sex, emotions, and earthworms until his death in 1882, when he was honored with burial at Westminster Abbey. This is a fresh, up-to-date account of the life and work of a most remarkable man.

This illuminating volume explores the effects of chance on evolution, covering diverse perspectives from scientists, philosophers, and historians. The evolution of species, from single-celled organisms to multicellular animals and plants, is the result of a long and highly chancy history. But how profoundly has chance shaped life on earth? And what, precisely, do we mean by chance? Bringing together biologists, philosophers of science, and historians of science, Chance in Evolution is the first book to untangle the far-reaching effects of chance, contingency, and randomness on the evolution of life. The book begins by placing chance in historical context, starting with the ancients and moving through Darwin to contemporary biology. It documents the shifts in our understanding of chance as Darwin’s theory of evolution developed into the modern synthesis, and how the acceptance of chance in Darwinian theory affected theological resistance to it. Other chapters discuss how chance relates to the concepts of genetic drift, mutation, and parallel evolution—as well as recent work in paleobiology and the experimental evolution of microbes. By engaging in collaboration across biology, history, philosophy, and theology, this book offers a comprehensive overview both of the history of chance in evolution and of our current understanding of the impact of chance on life.

Leading paleontologist J. David Archibald explores the rich history of visual metaphors for biological order from ancient times to the present and their influence on humans' perception of their place in nature, offering uncommon insight into how we went from standing on the top rung of the biological ladder to embodying just one tiny twig on the tree of life. He begins with the ancient but still misguided use of ladders to show biological order, moving then to the use of trees to represent seasonal life cycles and genealogies by the Romans. The early Christian Church then appropriated trees to represent biblical genealogies. The late eighteenth century saw the tree reclaimed to visualize relationships in the natural world, sometimes with a creationist view, but in other instances suggesting evolution. Charles Darwin's On the Origin of Species (1859) exorcised the exclusively creationist view of the "tree of life," and his ideas sparked an explosion of trees, mostly by younger acolytes in Europe. Although Darwin's influence waned in the early twentieth century, by midcentury his ideas held sway once again in time for another and even greater explosion of tree building, generated by the development of new theories on how to assemble trees, the birth of powerful computing, and the emergence of molecular technology. Throughout Archibald's far-reaching study, and with the use of many figures, the evolution of "tree of life" iconography becomes entwined with our changing perception of the world and ourselves.

How the meaningless process of natural selection produces purposeful beings who find meaning in the world. In From Darwin to Derrida, evolutionary biologist David Haig explains how a physical world of matter in motion gave rise to a living world of purpose and meaning. Natural selection, a process without purpose, gives rise to purposeful beings who find meaning in the world. The key to this, Haig proposes, is the origin of mutable “texts”—genes—that preserve a record of what has worked in the world. These texts become the specifications for the intricate mechanisms of living beings. Haig draws on a wide range of sources—from Laurence Sterne's Tristram Shandy to Immanuel Kant's Critique of the Power of Judgment to the work of Jacques Derrida to the latest findings on gene transmission, duplication, and expression—to make his argument. Genes and their effects, he explains, are like eggs and chickens. Eggs exist for the sake of becoming chickens and chickens for the sake of laying eggs. A gene's effects have a causal role in determining which genes are copied. A gene (considered as a lineage of material copies) persists if its lineage has been consistently associated with survival and reproduction. Organisms can be understood as interpreters that link information from the environment to meaningful action in the environment. Meaning, Haig argues, is the output of a process of interpretation; there is a continuum from the very simplest forms of interpretation, instantiated in single RNA molecules near the origins of life, to the most sophisticated. Life is interpretation—the use of information in choice.
