Publisher's Note: The role of science in policymaking has gained unprecedented stature in the United States, raising questions about the place of science and scientific expertise in the democratic process. Some scientists have been given considerable epistemic authority in shaping policy on issues of great moral and cultural significance, and the politicizing of these issues has become highly contentious.

Since World War II, most philosophers of science have purported the concept that science should be “value-free.” In Science, Policy and the Value-Free Ideal, Heather E. Douglas argues that such an ideal is neither adequate nor desirable for science. She contends that the moral responsibilities of scientists require the consideration of values even at the heart of science. She lobbies for a new ideal in which values serve an essential function throughout scientific inquiry, but where the role values play is constrained at key points, thus protecting the integrity and objectivity of science. In this vein, Douglas outlines a system for the application of values to guide scientists through points of uncertainty fraught with moral valence.

Following a philosophical analysis of the historical background of science advising and the value-free ideal, Douglas defines how values should-and should not-function in science. She discusses the distinctive direct and indirect roles for values in reasoning, and outlines seven senses of objectivity, showing how each can be employed to determine the reliability of scientific claims. Douglas then uses these philosophical insights to clarify the distinction between junk science and sound science to be used in policymaking. In conclusion, she calls for greater openness on the values utilized in policymaking, and more public participation in the policymaking process, by suggesting various models for effective use of both the public and experts in key risk assessments.

Introduction: The social sciences have long had an inferiority complex. Because the social sciences emerged as distinct disciplines after the natural sciences, comparisons between the mature and successful natural sciences and the fledgling social sciences were quickly made. One of the primary concerns that arose was over the role of values in the social sciences. There were several reasons for this. First, the social sciences did not have the clear empirical successes that the natural sciences did in the seventeenth and eighteenth centuries to bolster confidence in their reliability. Some postulated that an undue influence of values on the social sciences contributed to this deficit of empirical success. Second, social sciences such as economics and psychology emerged from their philosophical precursors gradually and often carried with them the clear normative trappings of their disciplinary origins. Third, although formal rules on the treatment of human subjects would not emerge until the second half of the twentieth century, by the time the social sciences emerged, it was obvious there were both ethical and epistemic challenges to experimenting on human subjects and human communities. Controlled settings were (and are) often difficult to achieve (or are unethical to achieve), making clear empirical success even more elusive. Finally, there is the additional com-plication that social sciences invariably study and/or comment upon human values. All of these considerations lent credence to the view that social sciences were inevitably more value-laden, and as a result less reliable, than the natural sciences.

Abstract: Contemporary scientific and philosophical literature on perception often focuses on the relationship between perception and action, emphasizing the ways in which perception can be understood as geared towards action or ‘action-oriented’. In this paper I provide a framework within which to classify approaches to action-oriented perception, and I highlight important differences between the distinct approaches. I show how talk of perception as action-oriented can be applied to the evolutionary history of perception, neural or psychological perceptual mechanisms, the semantic content or phenomenal character of perceptual states, or to the metaphysical nature of perception. I argue that there are no straightforward inferences from one kind of action-oriented perception to another. Using this framework and its insights, I then explore the notion of action-oriented perceptual representation which plays a key role in some approaches to embodied cognitive science. I argue that the concept of action-oriented representation proposed by Clark and Wheeler is less straightforward than it might seem, because it seems to require both that the mechanisms of perceptual representation are action-oriented and that the content of these perceptual representations are action-oriented. Given that neither of these claims can be derived from the other, proponents of action-oriented representation owe us separate justification for each claim. I will argue that such justifications are not forthcoming in the literature, and that attempts to reconstruct them run into trouble: the sorts of arguments offered for the representational mechanisms being action-oriented seem to undermine the sorts of arguments offered for the representational content being action-oriented, and vice-versa.
