This important collection focuses on the nature and importance of biodiversity. The concept is clarified and its intrinsic and instrumental value are discussed. Even though the term biodiversity was invented in the 1980s to promote the cause of species conservation, discussions on biological diversity go back to Plato. There are many controversies surrounding biodiversity and a few of them are examined here: What is worthy of protection or restoration and what is the acceptable level of costs? Is it permissible to (...) kill sentient animals to promote native populations? Can species be reintroduced if they have disappeared a long time ago? How should the responsibilities for biodiversity be shared? This book will be of interest to philosophers of science and biologists, but also to anyone interested in conservation and the environment.

Most public discussion has focused on those effects of genetic research that are considered in some way unwanted or unpleasant. For example, there has been much debate concerning the risks and the ethical appropriateness of genetic screening, gene therapy, and agricultural applications based on genetic techniques. It often claimed that genetic research may cause new problems such as genetic discrimination, stigmatization, environmental risks, or mistreatment of animals.Genes and Morality: New Essays adopts a critical attitude toward genetic research, on both a (...) theoretical and a practical level. It presents some of the most important problems in the ethics of genetic engineering, including the questions of genetic health and disease, genetic testing, responsibility for health, patenting non-human and human life, and problems related to the disclosure of genetic information.The aim of the book is to focus on real ethical and conceptual issues. Consider, for instance, the concept of genetic disease. As one of the contributors, Ingmar Pörn, writes, "fear of genetic disease, or anxiety, is not itself a disease any more than fear of becoming unemployed is a disease. Alleviating such emotions is not a medical task to be discharged by drug therapy."The book also examines the philosophical foundations of these issues by discussing the most influential bioethical theories of today, including utilitarianism and principlism.

David Lewis [2] suggests that an adequate inductive method should be immodest, i.e. recommend itself as at least as accurate as any of its rivals. On this basis he works out a solution to the intricate problem of choosing among Carnap's λ-methods. Lewis himself points out certain undesirable consequences of his solution. I will argue that the solution breaks down for a more general reason than that indicated by Lewis; like other procedures for estimating degrees of belief I am familiar (...) with, it overlooks the component of lawlikeness of inductive situations. This is not to object to the requirement of immodesty; I only want to draw attention to certain assumptions which Lewis makes in deriving his equations and which seem to be unjustified. (shrink)
I want to show the importance of the notion of conatus for Hobbes' political philosophy. According to Hobbes, all motion of bodies consists of elementary motions he called 'endeavors.' They are motions 'made in less space and time than can be given,' and they obey the law of persistence or inertia. A body strives to preserve its state and resist the causal power of other bodies. I call this the conatus-principle. Hobbes' argument for social contract and sovereign is based essentially (...) on this model. He proves that the natural conatus makes people strive to preserve their lives and therefore to get out of the destructive state of nature; commit to mutual contracts; keep the contracts unless some external cause otherwise determines; and establish a permanent sovereign power that Hobbes calls 'an artificial eternity of life.' All this is determined by the fundamental laws of nature, essentially, by the conatus-principle. I also show that the Prisoner's Dilemma interpretation of the Hobbesian state of nature does not represent all of the essential features of Hobbes' argument. (shrink)
The idea of active power played central role in the 17th Century philosophy and science. The idea is as follows: if not prevented, bodies necessarily do certain things in virtue of their power. This kind of thought naturally arose from what might properly be called the law of persistence, according to which moving bodies continue their motion unchanged if no new external force intervenes.1 What bodies do in virtue of their power was called actions, and in terms of actions such (...) things as resistance, pressure and affections were explained. What is this active power? One of the main aims of philosophers in the 17th and 18th Centuries was to find a good answer to this question. (shrink)
