Lewis claims that Martin’s cases indeed refute the simple conditional analysis of dispositions and proposes the reformed conditional analysis that is purported to overcome them. In this paper I will first argue that Lewis’s defense of the reformed analysis can be understood to invoke the concepts of disposition-specific stimulus and manifestation. I will go on to argue that advocates of the simple analysis, just like Lewis, can also defend their analysis from alleged counterexamples including Martin’s cases by invoking the concepts (...) of disposition-specific stimulus and manifestation. This means that Lewis’s own necessary defense of the reformed analysis invalidates his motivation of it. Finally, I will argue that we have a good reason to favor the simple analysis over Lewis’s analysis. (shrink)

In ‘Finkish Dispositions’1 David Lewis proposes an analysis of dispositions which improves on the simple conditional analysis. In this paper I show that Lewis’ analysis still fails. I also argue that repairs are of no avail, and suggest why this is so.

Many philosophers think that dispositions are necessarily intrinsic. However, there are no good positive arguments for this view. Furthermore, many properties (such as weight, visibility, and vulnerability) are dispositional but are not necessarily shared by perfect duplicates. So, some dispositions are extrinsic. I consider three main objections to the possibility of extrinsic dispositions: the Objection from Relationally Specified Properties, the Objection from Underlying Intrinsic Properties, and the Objection from Natural Properties. These objections ultimately fail.

The formation of DNA photoproducts by ultraviolet (UV) light is responsible for induction of mutations and development of skin cancer. To understand UV mutagenesis, it is important to know the mechanisms of formation and repair of these lesions. Cyclobutane pyrimidine dimers and (6–4)photoproducts are the two major classes of UV‐induced DNA lesions. Their distribution along DNA sequences in vivo is strongly influenced by nucleosomes and other DNA binding proteins. Repair of UV photoproducts is dependent on the transcriptional status of the (...) sequences to be repaired and on the chromatin environment. Sensitive techniques are now available to study repair of UV damage at the level of nucleotide resolution in mammalian cells. With the aid of in vitro systems, the entire nucleotide excision repair process has been reconstituted from purified protein components with naked DNA as a substrate. Future work will focus on the development of in vitro assays for transcription‐coupled repair and repair in chromatin. (shrink)

David Lewis's work is of fundamental importance in many areas of philosophical inquiry and there are few areas of Anglo-American philosophy where his impact has not been felt. Lewis's philosophy also has a rare unity: his views form a comprehensive philosophical system, answering a broad range of questions in metaphysics, philosophy of mind, philosophy of language, philosophy of action and many other areas. This breadth of Lewis's work, however, has meant that it is difficult to know where to start in (...) Lewis's work and a casual reader may often miss some of the illuminating connections between apparently quite disparate pieces of Lewis's work. This book aims to make this body of work more accessible to a general philosophical readership, while also providing a unified overview of the many contributions Lewis has made to contemporary Anglo-American philosophy. The book can be divided into four parts. The first part examines Lewis's metaphysical picture - one of the areas where he has had the greatest impact and also the framework for the rest of his theories. The second section discusses Lewis's important contributions in the philosophy of mind, language and meaning. The third part explores some of Lewis's work in decision theory, metaethics and applied ethics, areas where his work in not necessarily as widely appreciated, but in which he has done a range of work that is both accessible and important. The final section focuses on Lewis's distinctive philosophical method, perhaps one of his most significant legacies, which combines naturalism with "common-sense" theorizing. (shrink)

George Molnar came to see that the solution to a number of the problems of contemporary philosophy lay in the development of an alternative to Hume's metaphysics. This alternative would have real causal powers at its centre. Molnar set about developing a thorough account of powers that might persuade those who remained, perhaps unknowingly, in the grip of Humean assumptions. He succeeded in producing something both highly focused and at the same time wide-ranging. He showed both that the notion of (...) a power was central and that it could serve to dispel a number of long-standing philosophical problems.Molnar's account of powers is as realist as any that has so far appeared. He shows that dispositions are as real as any other properties. Specifically, they do not depend for their existence on their manifestations. Nevertheless, they are directed towards such manifestations. Molnar thus appropriates the notion of intentionality, from Brentano, and argues that it is the essential characteristic of powers. He offers a persuasive case for there being some basic and ungrounded powers, thus ruling out the reducibility of the dispositional to the non-dispositional. However, he does allow that there are non-power properties as well as power properties. In this respect, his final position is dualistic.This is contemporary metaphysics of the highest quality. It is a work that was almost complete when its author died. It has been edited for publication by another specialist in the subject, Stephen Mumford, who has also provided an introduction that will allow non-specialists to become acquainted with the issues. David Armstrong, one of the greatest living metaphysicians and personal friend of George Molnar, has provided a Foreword. (shrink)

Many years ago, C.B. Martin drew our attention to the possibility of ‘finkish’ dispositions: dispositions which, if put to the test would not be manifested, but rather would disappear. Thus if x if finkishly disposed to give response r to stimulus s, it is not so that if x were subjected to stimulus r, x would give response z; so finkish dispositions afford a counter‐example to the simplest conditional analysis of dispositions. Martin went on to suggest that finkish dispositions required (...) a theory of primitive causal powers; there, I think, he was mistaken. All that they require is an improved conditional analysis, and this improved analysis can be built upon whatever treatments of properties and of laws we may favour on other grounds. (shrink)

Causation is everywhere in the world: it features in every science and technology. But how much do we understand it? Mumford and Anjum develop a new theory of causation based on an ontology of real powers or dispositions. They provide the first detailed outline of a thoroughly dispositional approach, and explore its surprising features.

This essay deals with the question of the morality of abortion and infanticide. The fundamental ethical objection traditionally advanced against these practices rests on the contention that human fetuses and infants have a right to life, and it is this claim that is the primary focus of attention here. Consequently, the basic question to be discussed is what properties a thing must possess in order to have a serious right to life. The approach involves defending, then, a basic principle specifying (...) a condition living things must satisfy to have a serious right to life, and the answer given makes it unlikely that this condition is satisfied by human fetuses and infants, though this tentative conclusion could be altered by future scientific studies of the development of the human brain. As things stand at the moment, however, it seems unlikely that developing humans acquire the physical basis of the psychological capacities on which the right to continued existence rests, and therefore unless there are other substantial objections to abortion and infanticide that undercut the above line of thought, the conclusion is that such practices are not intrinsically wrong.
