The official model of explanation proposed by the logical empiricists, the covering law model, is subject to familiar objections. The goal of the present paper is to explore an unofficial view of explanation which logical empiricists have sometimes suggested, the view of explanation as unification. I try to show that this view can be developed so as to provide insight into major episodes in the history of science, and that it can overcome some of the most serious difficulties besetting the (...) covering law model.

What's the Use of Philosophy? aims to answer the question posed in its title, whether the questioner intends to dismiss philosophy, or seeks a positive answer. The first three chapters explore the grounds for dismissal. Chapter 1 expresses skepticism about the value of much professional Anglophone philosophy, while recognizing virtues in work often viewed as peripheral. Chapter 2 studies a philosophical subfield, the philosophy of science, arguing that, while its condition may be better than the norm, it is far from (...) perfect. In Chapter 3, a more systematic critique is offered, in the form of a pathology report. Its diagnosis identifies six justifiable philosophical impulses that, when pursued obsessively, generate distortions and diseases: clarity becomes a fetish, formalism becomes obfuscation, "intuition" is given burdens it cannot bear, appeals to the a priori sprinkle fairy dust on controversial claims, ideas grabbed from other fields are used in cartoon forms, and questions no longer relevant are treated as if they were "timeless." Chapter 4 attempts to identify the legitimate goals of philosophy. It sees value in attempts to respond to questions arising from the difficulties of the age, in attempts to reform methods of inquiry, and, above all, in the construction of syntheses capable of helping people as they struggle to make sense of their lives. Philosophy is renewed when these traditional goals once again become central to its discussions. The final chapter responds to a frequently voiced worry in a letter to young philosophers who wonder how they can align their aspirations with the hyper-professionalism expected of them. (shrink)

I attempt to respond to the many questions and objections raised by the commentaries. The responses are grouped by themes, rather than focusing on the essays in sequence. So there are sections on worries about my analytical history, concerns about my meta-ethical perspective, doubts about my normative stance and complaints about my perpetration of a ‘naturalistic fallacy’.

I defend a view of the species category, pluralistic realism, which is designed to do justice to the insights of many different groups of systematists. After arguing that species are sets and not individuals, I proceed to outline briefly some defects of the biological species concept. I draw the general moral that similar shortcomings arise for other popular views of the nature of species. These shortcomings arise because the legitimate interests of biology are diverse, and these diverse interests are reflected (...) in different legitimate approaches to the classification of organisms. In the final section, I show briefly how the pluralistic approach can help to illuminate some areas of biological and philosophical dispute. (shrink)

The central project of the Critique of Pure Reason is to answer two sets of questions: What can we know and how can we know it? and What can't we know and why can't we know it? The essays in this collection are intended to help students read the Critique of Pure Reason with a greater understanding of its central themes and arguments, and with some awareness of important lines of criticism of those themes and arguments.

My comments focus on Proops’s treatment of the Paralogisms. I agree with many aspects of his discussion, including his views about the project of Rational Psychology and his analyses of how, exactly, the arguments of the Paralogisms are defective in form, but I disagree with his interpretation of the First Paralogism. I argue that the source of confusion that Kant diagnoses is not the grammatical distribution of ‘I’ as singular, but the fact that the I-representation is both empty and necessary (...) for cognition.

A landmark work of environmental philosophy that seeks to transform the debate about climate change. As the icecaps melt and the sea levels rise around the globe—threatening human existence as we know it—climate change has become one of the most urgent and controversial issues of our time. For most people, however, trying to understand the science, politics, and arguments on either side can be dizzying, leading to frustrating and unproductive debates. Now, in this groundbreaking new work, two of our most (...) renowned thinkers present the realities of global warming in the most human of terms—everyday conversation—showing us how to convince even the most stubborn of skeptics as to why we need to act now. Indeed, through compelling Socratic dialogues, Philip Kitcher and Evelyn Fox Keller tackle some of the thorniest questions facing mankind today: Is climate change real? Is climate change as urgent as the “scientists” make it out to be? How much of our current way of life should we sacrifice to help out a generation that won’t even be born for another hundred years? Who would pay for the enormous costs of making the planet "green?" What sort of global political arrangement would be needed for serious action? These crucial questions play out through familiar circumstances, from an older husband and wife considering whether they should reduce their carbon footprint, to a first date that evolves into a passionate discussion about whether one person can actually make a difference, to a breakfast that becomes an examination over whether or not global warming is really happening. Entertaining, widely accessible, and thoroughly original, the result promises to inspire dialogue in many places, while also giving us a line of reasoning that explodes the so-far impenetrable barriers of obfuscation that have surrounded the discussion. While the Paris Agreement was an historic achievement that brought solutions within the realm of possibility, The Seasons Alter is a watershed book that will show us how to make those possibilities a reality.

According to the cliché a picture is worth a thousand words. But this is a canard, for it vastly underestimates the expressive power of many pictures and diagrams. In this note we show that even a simple map such as the outline of Manhattan Island, accompanied by a pointer marking North, implies a vast infinity of statements—including a vast infinity of true statements.

Philip Kitcher and I agree that cognitive values are not only intelligible but play an important role in scientific inquiry. We also agree that the importance of authority is critical to understanding the social dimension of such inquiry. We disagree rather deeply concerning what the roles of cognitive goals and the social dimension are.

This paper attempts to understand kant's obscure remarks that certain parts of natural science are a priori or have something akin to an a priori status. i argue that kant does not claim that propositions of physics are fully a priori, that the notion of a proposition's being a priori "given an empirical concept" can be explicated, that kant's attempted defense of the status of parts of dynamics is deeply flawed because of his commitments about a priority, but that his (...) account of natural science contains some important insights.

During the last three decades, reflections on the growth of scientific knowledge have inspired historians, sociologists, and some philosophers to contend that scientific objectivity is a myth. In this book, Kitcher attempts to resurrect the notions of objectivity and progress in science by identifying both the limitations of idealized treatments of growth of knowledge and the overreactions to philosophical idealizations. Recognizing that science is done not by logically omniscient subjects working in isolation, but by people with a variety of (...) personal and social interests, who cooperate and compete with one another, he argues that, nonetheless, we may conceive the growth of science as a process in which both our vision of nature and our ways of learning more about nature improve. Offering a detailed picture of the advancement of science, he sets a new agenda for the philosophy of science and for other "science studies" disciplines. (shrink)

Most people believe that extraterrestrial beings or porpoises or computers could someday be recognized as persons. Given the significant constitutional differences between these entities and ourselves, the general assumption appears to be that ‘person’ is not a natural kind term. David Wiggins offers an illuminating challenge to this popular dogma in ‘Locke, Butler and the Stream of Consciousness: and Men as a Natural Kind’. Wiggins does not claim that ‘person’ actually is a natural kind term; but he argues hard for (...) the advantages of regarding it as something like a natural kind classification. The problem is that, whatever its merits, there are obvious and fatal objections to the view that person is a natural kind. My aim is to present a modification of the natural kind thesis which avoids these objections and retains the attractions of the basic position. (shrink)

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)

History and Philosophy of Modern Mathematics was first published in 1988. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. The fourteen essays in this volume build on the pioneering effort of Garrett Birkhoff, professor of mathematics at Harvard University, who in 1974 organized a conference of mathematicians and historians of modern mathematics to examine how the two disciplines approach the history of mathematics. In (...) History and Philosophy of Modern Mathematics, William Aspray and Philip Kitcher bring together distinguished scholars from mathematics, history, and philosophy to assess the current state of the field. Their essays, which grow out of a 1985 conference at the University of Minnesota, develop the basic premise that mathematical thought needs to be studied from an interdisciplinary perspective. The opening essays study issues arising within logic and the foundations of mathematics, a traditional area of interest to historians and philosophers. The second section examines issues in the history of mathematics within the framework of established historical periods and questions. Next come case studies that illustrate the power of an interdisciplinary approach to the study of mathematics. The collection closes with a look at mathematics from a sociohistorical perspective, including the way institutions affect what constitutes mathematical knowledge. (shrink)

Instead of conceiving ethical commands as divine revelations or as the discoveries of brilliant thinkers, we should see our ethical practices as evolving over tens of thousands of years, as members of our species have worked out how to live together and prosper. Here, Kitcher elaborates his radical vision of this millennia-long ethical project.

In this paper we make a proposal for reforming biomedical research that is aimed to align re-search more closely with the so-called fair-share principle according to which the proportions of global resources as-signed to different diseases should agree with the ratios of human suffering associated with those diseases.

The relationship between truth and politics has rarely seemed more vexed. Worries about misinformation and disinformation abound, and the value of expertise for democratic decision-making dismissed. Whom can we trust to provide us with reliable testimony? In Truth and Evidence, the latest in the NOMOS series, Melissa Schwartzberg and Philip Kitcher present nine timely essays shedding light on practices of inquiry. These essays address urgent questions including what it means to #BelieveWomen; what factual knowledge we require to confront challenges (...) like COVID-19; and how white supremacy shapes the law of evidence.

Claims that science should be more democratic than it is frequently arouse opposition. In this essay, I distinguish my own views about the democratization of science from the more ambitious theses defended by Paul Feyerabend. I argue that it is unlikely that the complexity of some scientific debates will allow for resolution according to the methodological principles of any formal confirmation theory, suggesting instead that major revolutions rest on conflicts of values. Yet these conflicts should not be dismissed as irresoluble.

Offering an engaging and accessible portrait of the current state of the field, Philosophy of Science: A New Introduction shows students how to think philosophically about science and why it is both essential and fascinating to do so. Gillian Barker and Philip Kitcher reconsider the core questions in philosophy of science in light of the multitude of changes that have taken place in the decades since the publication of C.G. Hempel's classic work, Philosophy of Natural Science —both in the (...) field and also in history and sociology of science and the sciences themselves. They explore how philosophical questions are connected to vigorous current debates—including climate change, science and religion, race, intellectual property rights, and medical research priorities—showing how these questions, and philosophers' attempts to answer them, matter in the real world. Featuring numerous illustrative examples and extensive further reading lists, Philosophy of Science: A New Introduction is ideal for courses in philosophy of science, history and philosophy of science, and epistemology/theory of knowledge. It is also compelling and illuminating reading for scientists, science students, and anyone interested in the natural sciences and in their place in global society today. (shrink)

The internet has considerably changed epistemic practices in science as well as in everyday life. Apparently, this technology allows more and more people to get access to a huge amount of information. Some people even claim that the internet leads to a democratization of knowledge. In the following text, we will analyze this statement. In particular, we will focus on a potential change in epistemic structure. Does the internet change our common epistemic practice to rely on expert opinions? Does it (...) alter or even undermine the division of epistemic labor? The epistemological framework of our investigation is a naturalist-pragmatist approach to knowledge. We take it that the internet generates a new environment to which people seeking information must adapt. How can they, and how should they, expand their repertory of social markers to continue the venture of filtering, and so make use of the possibilities the internet apparently provides? To find answers to these questions we will take a closer look at two case studies. The first example is about the internet platform WikiLeaks that allows so-called whistle-blowers to anonymously distribute their information. The second case study is about the search engine Google and the problem of personalized searches. Both instances confront a knowledge-seeking individual with particular difficulties which are based on the apparent anonymity of the information distributor. Are there ways for the individual to cope with this problem and to make use of her social markers in this context nonetheless? (shrink)

Traditional approaches to theory structure and theory change in science do not fare well when confronted with the practice of certain fields of science. We offer an account of contemporary practice in molecular biology designed to address two questions: Is theory change in this area of science gradual or saltatory? What is the relation between molecular biology and the fields of traditional biology? Our main focus is a recent episode in molecular biology, the discovery of enzymatic RNA. We argue that (...) our reconstruction of this episode shows that traditional approaches to theory structure and theory change need considerable refinement if they are to be defended as generally applicable. 1This paper emerged from discussions between us, and we are both equally responsible for its errors. We would like to thank Yvonne Paterson for helpful comments. (shrink)
