Where the ‘can’ is not the ‘can’ of physical impossibility the principle is false; the principle can be shown to be false when it is read this way by an examination of the role of excuses, which is not that of removing obligations. Part II) demonstrates how the misapplication (...) of the ‘“ought” implies “can”’ principle is utilized in a chain of confusion: a confusion of excuses and justifications with respect to obligations and a confusion of the relation between obligations and blameworthiness.

Laymen and philosophers alike find it counterintuitive to consent to the assertion that “it is sometimes right not to follow the requirements of morality”. This may be because the conventions of ordinary language do much to encourage the view that “morally ought to do” functions as an equivalent for “what one ought to do all things considered”. In this paper I will argue against such an equivalence and attempt to shake the holders of the prevailing view, that moral reasons are (...) always overriding, from their dogmatism. The primary theses of this paper are (1) there is no acceptable ordering of reasons for acting--not between types of reasons nor within the category of moral reasons, and (2) moral reasons are not unconditional or unexceptionable.The body of this paper will include a discussion of various versions of the prevailing view (that reasons do have an order with moral reasons as overriding all reasons). I will make some brief remarks about several forms of simplification or reductionism which provide fertile ground for the prevailing view, specifically (a) efforts to transform ‘the all things considered ought’ into a ‘moral ought’ and (b) three efforts to offer a single principle as the basis of moral reasoning. Then I will attempt to reveal flaws in two contemporary expressions of the prevailing view; those of D.Z. Phillips and Kurt Baier. The bulk of my efforts will be directed at demonstrating the conditionality and overrideability of moral reasons. In the process I will also attempt to illuminate the attractiveness of the, if I am correct, mistaken but prevailing view. And finally a moral will be drawn. (shrink)

This chapter critically analyzes evolutionary epistemology as a theoretical framework for the study of science as a historical and cultural phenomenon. As spelled out by Campbell in the 1970s, evolutionary epistemology has an ambitious goal: it aims at understanding the complex relations between bio- logical evolution, especially the biological evolution of human cognition, and the cultural evolution of scientific knowledge. It eventually aims at forming an integrated causal theory of the evolution of science, starting with the evo- lution of human (...) cognition. In this chapter, the author considers Campbell’s project and specifies why it is still today a worthwhile project for explain- ing the evolution of science as a specific case of cultural evolution. But he also criticizes Campbell’s evolutionary epistemology for assuming that blind variation and selective retention are the processes through which science evolves. This assumption, the author argues, is at odds with much of what we know about scientific cognition and the history of science. He advocates (1) dropping the methodological constraint of looking for processes of blind variation and selective retention at the expense of other constructive processes and mechanisms of knowledge production; but (2) retaining the integrative point of evolutionary epistemology, which implies taking seriously the results of evolutionary psychology; and (3) retaining the populational framework for explaining the history of science, which means questioning why some scientific beliefs and practices eventually spread and stabilize in a scientific community. We end up with an updated research program for evolutionary epistemology, which faces new challenges. (shrink)

Après avoir présenté et expliqué la notion de cognition distribuée, je situerai l'analyse qu'elle permet au sein des sciences cognitives et de la sociologie. Mes buts sont de montrer en quoi la théorie de la cognition distribuée contribue aux théories de la psychologie et de la sociologie, et réciproquement comment les théories de la sociologie et de la psychologie peuvent être recrutées pour expliquer l'existence de systèmes de cognition distribuée. La troisième section de ce chapitre est centrée sur les relations (...) entre psychologie et théorie de la cognition distribuée. Elle montre que la sociologie de la cognition distribuée béné à être une sociologie cognitive de la cognition distribuée. La quatrième partie continue cet argument, mais en soulignant les phénomènes typiquement sociologique qui interviennent dans la constitution et l'évolution des systèmes de cognition distribuèe.

A systematic theory of naturalism, bridging metaphysics and the science of complexity and emergence.

Studying institutions as part of the research on cultural evolution prompts us to analyze one very important mechanism of cultural evolution: institutions do distribute cultural variants in the population. Also, it enables relating current research on cultural evolution to some more traditional social sciences: institutions, often seen as macro-social entities, are analyzed in terms of their constitutive micro-phenomena. This article presents Sperber’s characterization of institutions, and then gives some hints about the set of phenomena to which it applies.

Humans massively depend on communication with others, but this leaves them open to the risk of being accidentally or intentionally misinformed. To ensure that, despite this risk, communication remains advantageous, humans have, we claim, a suite of cognitive mechanisms for epistemic vigilance. Here we outline this claim and consider some of the ways in which epistemic vigilance works in mental and social life by surveying issues, research and theories in different domains of philosophy, linguistics, cognitive psychology and the social sciences.

This work aims to defines the question Is there a human nature? It argues that we know our nature only when it is recognized by our culture and that the liberal democratic idea of the state both celebrates and threatens the notion of fundamental human equality.

Logic and Computation is concerned with techniques for formal theorem-proving, with particular reference to Cambridge LCF (Logic for Computable Functions). Cambridge LCF is a computer program for reasoning about computation. It combines methods of mathematical logic with domain theory, the basis of the denotational approach to specifying the meaning of statements in a programming language. This book consists of two parts. Part I outlines the mathematical preliminaries: elementary logic and domain theory. They are explained at an intuitive level, giving references (...) to more advanced reading. Part II provides enough detail to serve as a reference manual for Cambridge LCF. It will also be a useful guide for implementors of other programs based on the LCF approach. (shrink)

The study of the physical world had its origins in philosophy, and, two-and-one-half millennia later, the scientific advances of the twentieth century are bringing the two fields closer together again. So argues Lawrence Sklar in this brilliant new text on the philosophy of physics.Aimed at students of both disciplines, Philosophy of Physics is a broad overview of the problems of contemporary philosophy of physics that readers of all levels of sophistication should find accessible and engaging. Professor Sklar’s talent for (...) clarity and accuracy is on display throughout as he guides students through the key problems: the nature of space and time, the problems of probability and irreversibility in statistical mechanics, and, of course, the many notorious problems raised by quantum mechanics.Integrated by the theme of the interconnectedness of philosophy and science, and linked by many references to the history of both disciplines, Philosophy of Physics is always clear, while remaining faithful to the complexity and integrity of the issues. It will take its place as a classic text in a field of fundamental intellectual importance. (shrink)

Prior to the twentieth century, theories of knowledge were inherently perceptual. Since then, developments in logic, statis- tics, and programming languages have inspired amodal theories that rest on principles fundamentally different from those underlying perception. In addition, perceptual approaches have become widely viewed as untenable because they are assumed to implement record- ing systems, not conceptual systems. A perceptual theory of knowledge is developed here in the context of current cognitive science and neuroscience. During perceptual experience, association areas in the (...) brain capture bottom-up patterns of activation in sensory-motor areas. Later, in a top-down manner, association areas partially reactivate sensory-motor areas to implement perceptual symbols. The stor- age and reactivation of perceptual symbols operates at the level of perceptual components – not at the level of holistic perceptual expe- riences. Through the use of selective attention, schematic representations of perceptual components are extracted from experience and stored in memory (e.g., individual memories of green, purr, hot). As memories of the same component become organized around a com- mon frame, they implement a simulator that produces limitless simulations of the component (e.g., simulations of purr). Not only do such simulators develop for aspects of sensory experience, they also develop for aspects of proprioception (e.g., lift, run) and introspec- tion (e.g., compare, memory, happy, hungry). Once established, these simulators implement a basic conceptual system that represents types, supports categorization, and produces categorical inferences. These simulators further support productivity, propositions, and ab- stract concepts, thereby implementing a fully functional conceptual system. Productivity results from integrating simulators combinato- rially and recursively to produce complex simulations. Propositions result from binding simulators to perceived individuals to represent type-token relations. Abstract concepts are grounded in complex simulations of combined physical and introspective events. Thus, a per- ceptual theory of knowledge can implement a fully functional conceptual system while avoiding problems associated with amodal sym- bol systems. Implications for cognition, neuroscience, evolution, development, and artificial intelligence are explored. (shrink)

If Christian theology is that enterprise whose essential purpose is to understand the faith of the Christian Church, then it must approach that faith from the perspective not only of its transcendent source, but also as a human achievement, a creative interpretation of those events in which transcendent reality discloses itself for appropriation. Few theologians would deny that theology has to do primarily with the ways in which ultimate reality becomes manifest in human beings' faithful responses, in belief and trust, (...) to its self-disclosures, preparatory and decisive. But the implications of such a view are not always confronted straightforwardly, especially for the suitable normative principles by which theology must assess the adequacy of the church's expressions of its faith. This essay seeks to probe how an account of the Christian faith could proceed whose norm derives not from the revelatory source of faith but from the dynamic of human creativity within which alone faith's source, in being interpreted, becomes clear, cogent, and decisive for conscious existence.

Aboriginal peoples are forever explaining themselves to non-Aboriginal people: telling their stories, explaining their beliefs and ceremonies, and introducing ideas that have never crossed the non-Aboriginal mind. Western knowledge operates from a linear, singular view; it views the world from order beneath chaos; it is very noun oriented; knowledge is about oneself in relation to everything else in a relativistic sense. Aboriginal knowledge has a very different “coming to know.” It is holistic and cyclical; it views the world from chaos (...) underneath order; its languages are process and action oriented. Knowledge is about participation in and with the natural world. (shrink)

About the Series Contemporary philosophy of science combines a general study from a philosophical perspective of the methods of science, with an inquiry, again from the philosophical point of view, into foundational issues that arise in the various special sciences. Methodological philosophy of science has deep connections with issues at the center of pure philosophy. It makes use of important results, for example, in traditional epistemology, metaphysics and the philosophy of language. It also connects in various ways with other disciplines (...) such as the history and sociology of the sciences, with pure logic, and with such branches of mathematics as probability theory. These volumes are, for the most part, devoted to readings in the methodological aspects of the philosophy of science. One volume, however, takes up the philosophical issues in the foundations of a particularly important special science, that is the issues in the foundations of theories of contemporary physics. The methodological volumes cover a number of crucial general problem areas. The first volume takes up issues in the nature of scientific explanation, and the related issues of the nature of scientific law and of the casual relation among events. The second volume explores issues in the nature and structure of scientific theories. The third volume collects inquiries into the nature of scientific change, as one theory is replaced by another. Volume four is devoted to readings concerning the nature of probability and the nature and justification of inductive reasoning in science. The following volume continues the exploration of the issue of confirming and rejecting theories with a series of readings devoted to Bayesian methodologies in science and to the exploration of non-inductive strategies for rationalizing belief. Finally, volume six explores three major problem areas in the foundation of physics: the nature and rationale for physical theories of space and time; the interpretive problems arising out of the quantum theory; and some puzzles arising out of statistical mechanical theories of physics. The readings are selected and arranged to provide the user with systematic access to the most important contemporary themes in methodological philosophy of science and in philosophy of physics. The selections include many recent contributions to the field, as well as papers and extracts from books and journals otherwise not easily available. (shrink)

Jnanasrimitra (975-1025) was regarded by both Buddhists and non-Buddhists as the most important Indian philosopher of his generation. His theory of exclusion combined a philosophy of language with a theory of conceptual content to explore the nature of words and thought. Jnanasrimitra's theory informed much of the work accomplished at Vikramasila, a monastic and educational complex instrumental to the growth of Buddhism. His ideas were also passionately debated among successive Hindu and Jain philosophers. This volume marks the first English translation (...) of Jnanasrimitra's Monograph on Exclusion, a careful, critical investigation into language, perception, and conceptual awareness. Featuring the rival arguments of Buddhist and Hindu intellectuals, among other thinkers, the Monograph reflects more than half a millennium of competing claims while providing an invaluable introduction to a crucial philosopher. Lawrence J. McCrea and Parimal G. Patil familiarize the reader with the author, themes, and topics of the text and situate Jnanasrimitra's findings within his larger intellectual milieu. Their clear, accessible, and accurate translation proves the influence of Jnanasrimitra on the foundations of Buddhist and Indian philosophy. (shrink)

Reasoning, defined as the production and evaluation of reasons, is a central process in science. The dominant view of reasoning, both in the psychology of reasoning and in the psychology of science, is of a mechanism with an asocial function: bettering the beliefs of the lone reasoner. Many observations, however, are difficult to reconcile with this view of reasoning; in particular, reasoning systematically searches for reasons that support the reasoner’s initial beliefs, and it only evaluates these reasons cursorily. By contrast, (...) reasoners are well able to evaluate others’ reasons: accepting strong arguments and rejecting weak ones. The argumentative theory of reasoning accounts for these traits of reasoning by postulating that the evolved function of reasoning is to argue: to find arguments to convince others and to change one’s mind when confronted with good arguments. Scientific reasoning, however, is often described as being at odds with such an argumentative mechanisms: scientists are supposed to reason objectively on their own, and to be pigheaded when their theories are challenged, even by good arguments. In this article, we review evidence showing that scientists, when reasoning, are subject to the same biases as are lay people while being able to change their mind when confronted with good arguments. We conclude that the argumentative theory of reasoning explains well key features of scientists’ reasoning and that differences in the way scientists and laypeople reason result from the institutional framework of science.

Many kinds of relativism have been attributed to Karl Marx. We discuss three broad areas of Marx’s thinking: his theories of history, science, and morality. Along the way, we show that Marx is committed to a version of philosophical naturalism that privileges the results of genuine science over alternative ways of understanding the world. This outlook presupposes the possibility of objective knowledge of the world. It follows that Marx is no relativist (at least in the senses we consider). Unlike many (...) non-relativists, however, Marx pays close attention to the problems with which contemporary philosophers interested in relativism are most preoccupied: irresolvable moral disagreements between social groups, the evolution of institutions and practices over time, and the prominent, perhaps decisive role played by non-cognitive social factors in belief formation. We show how some later Marxists have mistaken this close attention for evidence that Marx himself is a relativist. (shrink)
