Laudan constructs a fresh approach to a longtime problem for the philosopher of science: how to explain the simultaneous and widespread presence of both agreement and disagreement in science. Laudan critiques the logical empiricists and the post-positivists as he stresses the need for centrality and values and the interdependence of values, methods, and facts as prerequisites to solving the problems of consensus and dissent in science.

In this collection of essays one of the preeminent philosophers of science writing offers a reinterpretation of the enduring significance of logical positivism, the revolutionary philosophical movement centered around the Vienna Circle in the 1920s and 30s. Michael Friedman argues that the logical positivists were radicals not by presenting a new version of empiricism but rather by offering a new conception of a priori knowledge and its role in empirical knowledge. This collection will be mandatory reading for any philosopher or (...) historian of science interested in the history of logical positivism in particular or the evolution of modern philosophy in general.

This book introduces a new approach to the issue of radical scientific revolutions, or "paradigm-shifts," given prominence in the work of Thomas Kuhn. The book articulates a dynamical and historicized version of the conception of scientific a priori principles first developed by the philosopher Immanuel Kant. This approach defends the Enlightenment ideal of scientific objectivity and universality while simultaneously doing justice to the revolutionary changes within the sciences that have since undermined Kant's original defense of this ideal. Through a modified (...) Kantian approach to epistemology and philosophy of science, this book opposes both Quinean naturalistic holism and the post-Kuhnian conceptual relativism that has dominated recent literature in science studies. Focussing on the development of "scientific philosophy" from Kant to Rudolf Carnap, along with the parallel developments taking place in the sciences during the same period, the author articulates a new dynamical conception of relativized a priori principles. This idea applied within the physical sciences aims to show that rational intersubjective consensus is intricately preserved across radical scientific revolutions or "paradigm-shifts and how this is achieved.

By targeting and critiquing these assumptions, he lays the groundwork for a post-positivist philosophy of science that does not provide aid and comfort to the enemies of reason. This book consists of thirteen essays.

Normative naturalism is a view about the status of epistemology and philosophy of science; it is a meta-epistemology. It maintains that epistemology can both discharge its traditional normative role and nonetheless claim a sensitivity to empirical evidence. The first sections of this essay set out the central tenets of normative naturalism, both in its epistemic and its axiological dimensions; later sections respond to criticisms of that species of naturalism from Gerald Doppelt, Jarrett Leplin and Alex Rosenberg.

The prescriptive force of methodological rules rests, I argue, on the acceptance of scientific theories; that of the most general methodological rules rests on theories in the philosophy of science, which differ from theories in the several sciences only in generality and abstraction. I illustrate these claims by reference to methodological disputes in social science and among philosophers of science. My conclusions substantiate those of Laudan except that I argue for the existence of transtheoretical goals common to all scientists and (...) concrete enough actually to have bearing on methodology. And I argue that Laudan is committed to such goals himself, willy nilly. (shrink)

In this essay, I criticize Laudan's view that methodological rules in science are best understood as hypothetical imperatives, for example, to realize cognitive aim A, follow method B. I criticize his idea that such rules are best evaluated by a naturalized philosophy of science which collects the empirical evidence bearing on the soundness of these rules. My claim is that this view yields a poor explanation of (1) the role of methodological rules in establishing the rationality of scientific practices, (2) (...) the debates scientists have over rival methodological rules, and (3) the reasons on the basis of which scientists actually embrace, challenge, or transform methodological rules. A better explanation is provided by treating at least some methodological rules as foundational standards of theory-appraisal which define the criteria of scientific truth, knowledge, evidence, proof, explanations, etc., for a certain tradition or community of scientific practice. Such standards are in turn grounded or challenged on the basis of their coherence or incoherence with a wider body of scientific judgments. This view leads away from a naturalized philosophy of science back to its more classical epistemological conception. (shrink)

The fact that the goals and methods of science, as well as its empirical conclusions, are subject to change, is shown to allow at once for: (a) the objectivity of warrant for knowledge claims; (b) the absence of a priori standards from epistemology; (c) the normative character of epistemology; and (d) the rationality of axiological innovation. In particular, Laudan's attempt to make axiological constraints undercut epistemic realism is confuted.

Michael Friedman’s Dynamics of Reason is a welcome contribution to the ongoing articulation of philosophical perspectives for understanding the sciences in the context of post-positivist philosophy of science. Two perspectives that have gained advocacy since the demise of the “received view” are Quinean naturalism and Kuhnian relativism. In his 1999 Stanford lectures, Friedman articulates and defends a neo-Kantian perspective for philosophy of science that opposes both of these perspectives. His proffered neo-Kantian perspective is presented within the context of the problem (...) of theory change or “scientific revolutions,” and its main feature is a conception of scientific knowledge that requires “relativized constitutive a priori principles.” The lectures make up the first part of the book; the second part of the book, “Fruits of Discussion,” is a further elaboration and defence of the ideas advanced in the lectures. The resulting book serves as a useful sequel to Friedman’s impressive historical studies in Foundations of Space-Time Theories, Kant and the Exact Sciences, and Reconsidering Logical Positivism. In the preface, Friedman tells us that this book represents the philosophical viewpoint that he has arrived at as a result of completing these works. As such, it is not surprising that the prominent themes of the book are ones that have occupied Friedman’s attention in the past, viz., the importance of a priori principles in the exact sciences, the conventionalism of the logical positivists, and, more generally, an articulation of what remains defensible in neo-Kantian philosophy of science.

In april 1872, with the caisson at a depth of seventy-odd feet and still no bedrock, two men died. The strain for Roebling was nearly unbearable, as his wife later said. On May 18, a third man died, and that same day Roebling made the most difficult and courageous decision of the project. Staking everything — the success of the bridge, his reputation, his career - he ordered a halt. The New York tower, he had concluded, could stand where it (...) was, at a depth of 78 feet 6 inches, not on bedrock, but on “hardpack” sand. From examinations of the strata he had determined to his own satisfaction that no movement had occured at the level since the time of deposit millions of years in the geologic past; so, he said, it was “good enough to found upon”.

The article presents a critical discussion of Larry Laudan's naturalistic metamethodological theory known as normative naturalism (NN). I examine the strongest extant objection to NN, and, with reference to ideas in Freedman ( Philosophy of Science , 66 (Proceedings), pp. S526-S537, 1999), show how NN survives it. I then go on to outline two problems that really do compromise NN. The first revolves around Laudan's conception of the relationship between scientific values and the history of science. Laudan argues we can (...) make sense of progress in science without seeing great scientists in the past as having held the cognitive values and methodological rules we hold today as important for science. I argue this is extremely implausible, and moreover that Laudan must see our values today as justified by reference to the values of past scientists if he is to avoid a pernicious form of relativism. The second problem with NN is that its conception of methodological rules--as hypothetical imperatives linking cognitive means to ends--is untenable. Such rules would not be needed in a scientific community; moreover it is doubtful whether they should class as rules at all. I conclude by suggesting that the distinction between cognitive means and ends which undergirds Laudan's view is intuitively not well founded, and in any case does not provide sufficient materials for a viable normative naturalized epistemology.
