Consideration of the counting and reidentification of particulars leads naturally enough to the orthodox doctrine that, “on pain of indefiniteness,” an identity statement in some way involves or presupposes a general term or “covering concept”: i.e., that the principium individuationis or criterion of identity implied depends upon the kind of thing in question. Thus it is said that an auditor understands the question whether A is the same as B only in so far as he knows, however informally or implicitly, (...) the answer to the supplementary question, “The same what?”.

This paper critically examines the claim that parallel distributed processing (PDP) networks are autonomous learning systems. A PDP model of a simple distributed associative memory is considered. It is shown that the 'generic' PDP architecture cannot implement the computations required by this memory system without the aid of external control. In other words, the model is not autonomous. Two specific problems are highlighted: (i) simultaneous learning and recall are not permitted to occur as would be required of an autonomous system; (...) (ii) connections between processing units cannot simultaneously represent current and previous network activation as would be required if learning is to occur. Similar problems exist for more sophisticated networks constructed from the generic PDP architecture. We argue that this is because these models are not adequately constrained by the properties of the functional architecture assumed by PDP modelers. It is also argued that without such constraints, PDP researchers cannot claim to have developed an architecture radically different from that proposed by the Classical approach in cognitive science.

This chapter outlines something of Mario Bunge’s long life and career as a physicist-philosopher originally living and working in Argentina for 40 years, then in Canada for nearly 60 years. It indicates the extraordinary breadth, depth and quantity of his research publications. It deals briefly with some key components of his work, such as: systemism, causation, theory analysis, axiomatization, ontology, epistemology, physics, psychology and philosophy of mind, social science, probability and Bayesianism, defence of the Enlightenment project, and education. Finally, the (...) chapter gives an account of the structure of the festschrift, and an indication of each of the 41 contributions. (shrink)

We all have moral beliefs. But what if one beleif conflicts with another? DePaul argues that we have to make our beliefs cohere, but that the current coherence methods are seriously flawed. It is not just the arguments that need to be considered in moral enquiry. DePaul asserts that the ability to make sensitive moral judgements is vital to any philosophical inquiry into morality. The inquirer must consider how her life experiences and experiences with literature, film and theatre have influenced (...) her capacity for making moral judgments and attempt to ensure that this capacity is neither naive nor corrupted.

History, Philosophy and Science Teaching argues that science teaching and science teacher education can be improved if teachers know something of the history and philosophy of science and if these topics are included in the science curriculum. The history and philosophy of science have important roles in many of the theoretical issues that science educators need to address: the goals of science education; what constitutes an appropriate science curriculum for all students; how science should be taught in traditional cultures; what (...) integrated science is; how scientific literacy can be promoted; and the conflict which can occur between science curriculum and deep-seated religious or cultural values and knowledge. In part, answers to these questions hinge on views about the nature of science, views that are best informed by historical and philosophical study. Outlining the history of liberal, or contextual, approaches to the teaching of science, Michael Matthews elaborates contemporary curriculum developments that explicitly address questions about the nature and the history of science. He provides examples of classroom teaching and develops useful arguments on constructivism, multicultural science education and teacher education. The book will appeal to school and university science teachers, educators of science teachers, and historians and philosophers of science. (shrink)

The first edition of The Scientific Background to Modern Philosophy took the dialogue of science and philosophy from Aristotle through to Newton. This second edition adds eight chapters, taking the dialogue through the Enlightenment and up to Darwin. This anthology is an attempt to help bridge the gap between the history of science and the history of philosophy.

One merit claimed for john rawls's coherence method, Wide reflective equilibrium, Is that it transcends the traditional two tiered approach to moral inquiry according to which one must choose as one's starting points either particular moral judgments or general moral principles. The two tiered conception of philosophical method is not limited to ethics. The most detailed exposition of the conception can be found in r m chisholm's various discussions of the problem of the criterion. While chisholm's work has played a (...) major role in structuring the way epistemologists think about method, It has not similarly influenced the deliberations of moral theorists. But moral philosophers are not the only ones with myopia, For neither rawls's coherentist method nor classical moral intuitionism figure in chisholm's taxonomy. One aim is to correct the vision of both parties by expanding chisholm's taxonomy in order to make clear how intuitionism and rawls's coherentist method are related to the methods identified by chisholm. My other aim is to argue for coherentism of the sort defended by rawls against the other non-Skeptical methods I consider. (shrink)

One aim philosophers have in constructing moral theories is to identify the natural or non-Moral characteristics that make actions right or obligatory, Things good, Or persons virtuous. Yet we have no clear understanding of what it is for certain of a thing's non-Moral properties to be responsible for its moral properties. Given the recent interest in the concept of supervenience one might think that the dependence of moral on natural properties could be explained in terms of it. Unfortunately, None of (...) the definitions of supervenience offered so far is adequate to this task, And indeed, There is some reason to think that this dependence relation is ultimately mysterious.

In the introduction to his account of the debate concerning religion between Cleanthes, Philo and Demea, Pamphilus remarks that ‘reasonable men may be allowed to differ where no one can reasonably be positive’. Pamphilus goes on to suggest that natural theology is an area that abounds with issues about which ‘no one can reasonably be positive’. Assuming that the beliefs of reasonable men are themselves reasonable, Pamphilus can be interpreted as holding that If no one is reasonably positive that the (...) proposition p is true or that it is false, a man might reasonably believe that p or might reasonably believe that not p.

The past decade has seen a renewed interest in moral psychology. A unique feature of the present endeavor is its unprecedented interdisciplinarity. For the first time, cognitive, social, and developmental psychologists, neuroscientists, experimental philosophers, evolutionary biologists, and anthropologists collaborate to study the same or overlapping phenomena. This review focuses on moral judgments and is written from the perspective of cognitive psychologists interested in theories of the cognitive and affective processes underlying judgments in moral domains. The review will first present and (...) discuss a variety of different theoretical and empirical approaches, including both behavioral and neuroscientific studies. We will then show how these theories can be applied to a selected number of specific research topics that have attracted particular interest in recent years, including the distinction between moral and conventional rules, moral dilemmas, the role of intention, and sacred/protected values. One overarching question we will address throughout the chapter is whether moral cognitions are distinct and special, or whether they can be subsumed under more domain-general mechanisms. (shrink)

This book examines solutions to the crisis of modernity proposed by the Spanish philosopher Miguel de Unamuno and the Mexican philosopher Antonio Caso. Acceptance of the objective claims of modern scientific rationality and the consequent rejection of the objective validity of artistic, moral, and religious claims generates the crisis of modernity. The problem is that of justifying artistic, moral, and religious claims. Miguel de Unamuno in his classic work,The Tragic Sense of Life, addresses the conflict between the belief in personal (...) immortality and modern scientific rationality. Holding that there is no rational justification for the belief in immortality, Unamuno finds a solution in a “saving scepticism” to act “as if” he deserved immortality. In his book Existence as Economy, as Art, and CharityCaso attempts to create an aposteriori metaphysics based on the “current” results of science supplemented by the intuitions of art and morality. In doing so, Caso believes that he has enlarged the scope of the knowable to include objects of art, morality, and religion. Unamuno, by accepting the strict line of demarcation between faith and reason has no other recourse but to turn to decisionism. By turning to intuitionism, Caso believes that he has blurred the line of demarcation. Decisionism and intuitionism, therefore, are worthy of further exploration. (shrink)

PDP networks that use nonmonotonic activation functions often produce hidden unit regularities that permit the internal structure of these networks to be interpreted (Berkeley et al., 1995; McCaughan, 1997; Dawson, 1998). In particular, when the responses of hidden units to a set of patterns are graphed using jittered density plots, these plots organize themselves into a set of discrete stripes or bands. In some cases, each band is associated with a local interpretation. On the basis of these observations, Berkeley (2000) (...) has suggested that these bands are both subsymbolic and symbolic in nature, and has used the analysis of one network to support the claim that there are fewer differences between symbols and subsymbols than one might expect. We suggest below that this conclusion is premature. First, in many cases the local interpretation of each band is difficult to relate to the interpretation of a network's response; a more appropriate relationship only emerges when a band associated with one hidden unit is considered in the context of other bands associated with other hidden units (i.e., interpretations of distributed representations are more useful than interpretations of local representations). Second, the content that a band designates to an external observer (i.e., the interpretation assigned to a band by the researcher) can be quite different from the content that a band designates to the output units of the network itself.. We use two different network simulations – including the one described by Berkeley (2000) – to illustrate these points. We conclude that current evidence involving interpretations of nonmonotonic PDP networks actually illustrates the differences between symbolic and subsymbolic processing. (shrink)

This chapter begins by noting the importance of debates in science education that hinge upon support for or rejection of the Enlightenment project. It then distinguishes the historic eighteenth-century Enlightenment from its articulation and working out in the Enlightenment project; details Mario Bunge’s and others’ summation of the core principles of the Enlightenment; and fleshes out the educational project of the Enlightenment by reference to the works of John Locke, Joseph Priestley, Ernst Mach, Philipp Frank and Herbert Feigl. It indicates (...) commonalities between the Enlightenment education project and that of the liberal education movement, and for both projects it points to the need to appreciate history and philosophy of science.

I’m not sure one even needs to think a state of affairs is true for us to take attitudinal pleasure in it. We surely take pleasure in imagining states of affairs. In such a case, we are well aware that the state of affairs that is the object of our enjoyment does not obtain. What is the proper account of the pleasure we take from imagining? I am fairly sure this is not a type of sensory pleasure. Would it make (...) sense to say that what S is attitudinally pleased by is the state of affairs consisting of S’s imagining p rather than p? I don’t think this will do. It seems possible for S to take pleasure in the imagined state of affairs, p, but not in the state of affairs of S’s imagining p. Consider the case of Chastity, who has had a puritanical upbringing. One day Chastity imagines a torrid romantic encounter with one of her co-workers. Quite in spite of herself, Chastity is pleased by the state of affairs which she merely imagines. But her upbringing has left its mark on her, so she feels very guilty about allowing her thoughts to run in such an unwholesome direction. Chastity is pained by the state of affairs consisting in her imagining the encounter. (shrink)

In this book, Rhodes provides a nonevaluative account of coercion. He begins with a thorough discussion of the charge that coercion is an essentially contested concept. He argues that effective communication of regulations pertaining to human conduct requires a basic level of clarity as to the kind of conduct being regulated. Accordingly, he argues that before we prescribe or proscribe conduct, we should describe it. In short, he maintains that wherever possible description should precede prescription and proscription. Rhodes begins his (...) descriptive project by providing a fundamental account of human motivation. Upon this foundation he supports his distinctions between threats, offers, throffers, and neutral proposals. He argues that all coercion claims can be understood in light of these components. He applies this analysis to three prominent accounts of coercion as advanced by F.A. Hayek, Harry Frankfurt, and Robert Nozick. After comparing and contrasting these views, Rhodes provides his own account. Rhodes's account is based upon the identification of what he refers to as perceived-threat-avoidance-behavior as a necessary condition for coercion. As a descriptive, or nonevaluative, account, Rhodes is able to identify coercion independent from normative judgments. He argues that it is not the wrongfulness of some conduct that makes it coercion, instead, it is the coerciveness of some conduct that makes it wrong. Unique to Rhodes's account, coercion is not necessarily wrong. As a descriptive account, his view permits an independent analysis of the moral status of an act of coercion. The book concludes with a discussion of the normatively significant variables of a coercion claim. (shrink)

What aspects and features of events impel people to label them as miraculous? Three studies examined people's miracle conceptions and the factors that lead them to designate an event as a miracle. Study 1 identified the basic elements of laypersons’ miracle beliefs by instructing participants to define a miracle, to list five events that they considered miraculous, and to state what they believed to be the purpose of miracles. Results showed that individuals tend to view miracles as highly improbable and (...) beneficial occurrences that instill hope and faith in people. Studies 2 and 3 investigated people's intuitive miracle theories. Findings demonstrated that people tend to label events as miracles when the events in question were of high magnitude, were obtained in an unusual manner, resulted in a beneficial health outcome, personally affected the participant, involved a person of worthy character, and depicted a low-probability event.

Sometimes a theory is interpreted realistically--i.e., as literally true--whereas sometimes a theory is interpreted instrumentalistically--i.e., as merely a convenient device for summarizing, systematizing, deducing, etc., a given body of observable facts. This paper is part of a program aimed at determining the basis on which scientists decide on which of these interpretations to accept a theory. I proceed by examining one case: the nineteenth-century debates about the existence of atoms. I argue that there was a gradual transition from an instrumentalist (...) to a realistic acceptance of the atomic theory, because of gradual increases in its predictive power, the "testedness" of its hypotheses, the "determinateness" of its quantities, and because of resolutions of doubts about the acceptability of its basic explanatory concepts.
