Richard Rudner famously argues that the communication of scientific advice to policy makers involves ethical value judgments. His argument has, however, been rightly criticized. This article revives Rudner’s conclusion, by strengthening both his lines of argument: we generalize his initial assumption regarding the form in which scientists must communicate their results and complete his ‘backup’ argument by appealing to the difference between private and public decisions. Our conclusion that science advisors must, for deep-seated pragmatic reasons, make value judgments is further (...) bolstered by reflections on how the scientific contribution to policy is far less straightforward than the Rudner-style model suggests.

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)

A number of philosophers of science and statisticians have attempted to justify conclusions drawn from a finite sequence of evidence by appealing to results about what happens if the length of that sequence tends to infinity. If their justifications are to be successful, they need to rely on the finite sequence being either indefinitely increasing or of a large size. These assumptions are often not met in practice. This paper analyzes a simple model of collecting evidence and finds that the (...) practice of collecting only very small sets of evidence before taking a question to be settled is rationally justified. This shows that the appeal to long run results can be used neither to explain the success of actual scientific practice nor to give a rational reconstruction of that practice. (shrink)

The most widely debated conception of democracy in recent years is deliberative democracy--the idea that citizens or their representatives owe each other mutually acceptable reasons for the laws they enact. Two prominent voices in the ongoing discussion are Amy Gutmann and Dennis Thompson. In Why Deliberative Democracy?, they move the debate forward beyond their influential book, Democracy and Disagreement.What exactly is deliberative democracy? Why is it more defensible than its rivals? By offering clear answers to these timely questions, Gutmann and (...) Thompson illuminate the theory and practice of justifying public policies in contemporary democracies. They not only develop their theory of deliberative democracy in new directions but also apply it to new practical problems. They discuss bioethics, health care, truth commissions, educational policy, and decisions to declare war. In "What Deliberative Democracy Means," which opens this collection of essays, they provide the most accessible exposition of deliberative democracy to date. They show how deliberative democracy should play an important role even in the debates about military intervention abroad.Why Deliberative Democracy? contributes to our understanding of how democratic citizens and their representatives can make justifiable decisions for their society in the face of the fundamental disagreements that are inevitable in diverse societies. Gutmann and Thompson provide a balanced and fair-minded approach that will benefit anyone intent on giving reason and reciprocity a more prominent place in politics than power and special interests.
