Cavalli-Sforza was among the first to ask whether the genes of modern populations contain a historical record of the human species. In answering to the affirmative, this title comprises five lectures that serve as a summation of the author's work in tracking a hundred thousand years of human evolution. Maps.

The utility of a notion testifies not to its clarity but rather to the philosophic importance of clarifying it. Even mistaken hypotheses and theories are of use in leading to discoveries. This remark is true in all the sciences. The genomic revolution raised hopes that the putative utility of race in biomedicine could be grounded in the view that race has a biological reality and scientific validity (Burchard et al. 2003; Risch et al. 2002). However, the rebuttal of the contention (...) that race is a biological category has been sharp among genomic scientists (Cooper, Kaufman, and Ward 2003; Long and Kittles 2003; Serre and Pääbo 2004). Some researchers worry about the reification of race in science and .. (shrink)

With this manifesto, John Dupré systematically attacks the ideal of scientific unity by showing how its underlying assumptions are at odds with the central conclusions of science itself.

Striving to boldly redirect the philosophy of science, this book by renowned philosopher Philip Kitcher examines the heated debate surrounding the role of science in shaping our lives. Kitcher explores the sharp divide between those who believe that the pursuit of scientific knowledge is always valuable and necessary--the purists--and those who believe that it invariably serves the interests of people in positions of power. In a daring turn, he rejects both perspectives, working out a more realistic image of the sciences--one (...) that allows for the possibility of scientific truth, but nonetheless permits social consensus to determine which avenues to investigate. He then proposes a democratic and deliberative framework for responsible scientists to follow. Controversial, powerful, yet engaging, this volume will appeal to a wide range of readers. Kitcher's nuanced analysis and authorititative conclusion will interest countless scientists as well as all readers of science--scholars and laypersons alike. (shrink)

Especially troublesome in this dispute is the status of the natural sciences, and this is where Hacking finds some of his most telling cases, from the conflict ...

A consensus view appears to prevail among academics from diverse disciplines that biological races do not exist, at least in humans, and that race -concepts and race -objects are socially constructed. The consensus view has been challenged recently by Robin O. Andreasen's cladistic account of biological race. This paper argues that from a scientific viewpoint there are methodological, empirical, and conceptual problems with Andreasen's position, and that from a philosophical perspective Andreasen's adherence to rigid dichotomies between science and society, facts (...) and values, nature and culture, and the biological and the social needs to be relinquished. DNA forensics is just one field of research that reveals how race remains both idea and object for human population biologists, an indication that it is premature to accept the existence of a no- race consensus across the disciplines. DNA forensics research also demonstrates ways in which race is reified by scientists by the representation of what is cultural or social as natural or biological, and of what is dynamic, relative, and continuous as static, absolute, and discrete. The philosophical analysis of foundational concepts of human population biology such as population, race, and ethnic group is best served by foregoing traditional objectivist approaches for a critical stance that recognises the inextricability of the biological and the social. Introduction Consensus view: biological races do not exist Andreasen's defence of the biological reality of races as clades Biological permutations of race Conclusion. (shrink)

In the ongoing debate concerning the nature of human racial categories, there is a trend to reject the biological reality of race in favour of the view that races are social constructs. At work here is the assumption that biological reality and social constructivism are incompatible. I oppose the trend and the assumption by arguing that cladism, in conjunction with current work in human evolution, provides a new way to define race biologically. Defining race in this way makes sense when (...) compared to the developments in other areas of systematic biology, where shared history has largely replaced morphological similarity as the foundation of a natural biological classification. Surprisingly, it turns out that cladistic races and social constructivism are compatible. I discuss a number of lessons about the way human biological races have been conceptualized. (shrink)

ArgumentThis paper investigates the conceptual treatment and mathematical modeling of force in Newton's Principia. It argues that, contrary to currently dominant views, Newton's concept of force is best understood as a physico-mathematical construct with theoretical underpinnings rather than a “mathematical construct” or an ontologically “neutral” concept. It uses various philosophical and historical frameworks to clarify interdisciplinary issues in the history of science and draws upon the distinction between axiomatic systems in mathematics and physics, as well as discovery patterns in science. (...) It also dwells on Newton's “philosophy” of mathematics, described here in terms of mathematical naturalism. This philosophy considers mathematical quantities to be physically significant quantities whose motions are best mapped by geometry. It then shows that to understand the epistemic status of force in the Principia, it is important to scrutinize both Newton's mathematical justificatory strategies and his background assumptions about force – without constructing, however, an overarching metaphysical framework for his science. Finally, the paper studies scientific attempts to redefine or eliminate force from science during the period between Newton and Laplace. From a philosophical standpoint, the paper implicitly suggests that questions about the reality of force be distinguished from questions about the validity of force, and that both sets of questions be distinguished from questions about the utility of the concept of force in science.
