Demonstrating the different roles that logic plays in the disciplines of computer science, mathematics, and philosophy, this concise undergraduate textbook covers select topics from three different areas of logic: proof theory, computability theory, and nonclassical logic. The book balances accessibility, breadth, and rigor, and is designed so that its materials will fit into a single semester. Its distinctive presentation of traditional logic material will enhance readers' capabilities and mathematical maturity. The proof theory portion presents classical propositional logic and first-order logic (...) using a computer-oriented (resolution) formal system. Linear resolution and its connection to the programming language Prolog are also treated. The computability component offers a machine model and mathematical model for computation, proves the equivalence of the two approaches, and includes famous decision problems unsolvable by an algorithm. The section on nonclassical logic discusses the shortcomings of classical logic in its treatment of implication and an alternate approach that improves upon it: Anderson and Belnap's relevance logic. Applications are included in each section. The material on a four-valued semantics for relevance logic is presented in textbook form for the first time. Aimed at upper-level undergraduates of moderate analytical background, Three Views of Logic will be useful in a variety of classroom settings. Gives an exceptionally broad view of logic. Treats traditional logic in a modern format. Presents relevance logic with applications. Provides an ideal text for a variety of one-semester upper-level undergraduate courses. (shrink)

This work helps highlights how the innovations in Flathman's thought have shaped the field of political theory and will be of interest to students and scholars alike.

Reviews evidence which suggests that there may be little or no direct introspective access to higher order cognitive processes. Ss are sometimes unaware of the existence of a stimulus that importantly influenced a response, unaware of the existence of the response, and unaware that the stimulus has affected the response. It is proposed that when people attempt to report on their cognitive processes, that is, on the processes mediating the effects of a stimulus on a response, they do not do (...) so on the basis of any true introspection. Instead, their reports are based on a priori, implicit causal theories, or judgments about the extent to which a particular stimulus is a plausible cause of a given response. This suggests that though people may not be able to observe directly their cognitive processes, they will sometimes be able to report accurately about them. Accurate reports will occur when influential stimuli are salient and are plausible causes of the responses they produce, and will not occur when stimuli are not salient or are not plausible causes.

The authors find East Asians to be holistic, attending to the entire field and assigning causality to it, making relatively little use of categories and formal logic, and relying on "dialectical" reasoning, whereas Westerners, are more analytic, paying attention primarily to the object and the categories to which it belongs and using rules, including formal logic, to understand its behavior. The 2 types of cognitive processes are embedded in different naive metaphysical systems and tacit epistemologies. The authors speculate that the (...) origin of these differences is traceable to markedly different social systems. The theory and the evidence presented call into question long-held assumptions about basic cognitive processes and even about the appropriateness of the process–content distinction. (shrink)

This book examines two questions: Do people make use of abstract rules such as logical and statistical rules when making inferences in everyday life? Can such abstract rules be changed by training? Contrary to the spirit of reductionist theories from behaviorism to connectionism, there is ample evidence that people do make use of abstract rules of inference -- including rules of logic, statistics, causal deduction, and cost-benefit analysis. Such rules, moreover, are easily alterable by instruction as it occurs in classrooms (...) and in brief laboratory training sessions. The fact that purely formal training can alter them and that those taught in one content domain can "escape" to a quite different domain for which they are also highly applicable shows that the rules are highly abstract. The major implication for cognitive science is that people are capable of operating with abstract rules even for concrete, mundane tasks; therefore, any realistic model of human inferential capacity must reflect this fact. The major implication for education is that people can be far more broadly influenced by training than is generally supposed. At high levels of formality and abstraction, relatively brief training can alter the nature of problem-solving for an infinite number of content domains. (shrink)

This classic, first published in 1969, introduces to English-speaking readers a field which is of increasing importance in contemporary philosophy and theology--hermeneutics, the theory of understanding, or interpretation. Richard E. Palmer, utilizing largely untranslated sources, treats principally of the conception of hermeneutics enunciated by Heidegger and developed into a "philosophical hermeneutics" by Hans-Georg Gadamer. He provides a brief overview of the field by surveying some half-dozen alternate definitions of the term and by examining in detail the contributions of Friedrich (...) Schleiermacher and Wilhelm Dilthey. In the Manifesto which concludes the book, Palmer suggests the potential significance of hermeneutics for literary interpretation. (shrink)

Contemporary fiscal theorizing largely assimilates the activities of government to that of some choosing agent. This paper explores an alternative approach where government is assimilated to an emergent process of complex interaction, as a form of complex adaptive system. Within this alternative vision, governments are treated not as objects of intervention into a market economy but as arenas of organized participation within it. While recent developments in computational modeling are starting to provide tools for probing such a vision, the roots (...) of that vision can be traced back to the spontaneous order theorists of the 18th century. After sketching some contours of this alternative vision, the remainder of the paper explores some possible implications of this change in vision for mapping the relationship among taxation, prosperity, and justice.

On autobiographical memory tests (AMTs) using positive and negative cue words, research has consistently found that depressed individuals (relative to nondepressed controls) are more likely to recall overgeneral memories (OGMs) and are less likely to recall specific memories. A total of 56 undergraduates who scored high or low on a measure of depression were shown positive and negative word cues and event cues in a computerised AMT. Dysphoric college students made significantly fewer specific and more categoric (overgeneral) responses than controls, (...) but did not differ from controls in terms of extended responses. Results suggest that the difference in memory specificity between low and high dysphoric students generalises across word and event cues and that a computerised version of the AMT can be used as an alternative to interviews as a form of administration.

This book is a critical and analytical survey of the major attempts, in modern philosophy, to deal with the phenomenon of intentionality—those of Descartes, Brentano, Meinong, Husserl, Frege, Russell, Bergmann, Chisholm, and Sellars. By coordinating the semantical approaches to the phenomenon, Dr. Aquila undertakes to provide a basis for dialogue among philosophers of different persuasions. "Intentionality" has become, since Franz Brentano revived its original medieval use, the standard term describing the mind's apparently paradoxical capacity to relate itself to objects existing (...) in the world. One approach to the phenomenon emphasizes the mental act. The author argues that the most adequate account involves elements of both approaches. Contemporary treatments tend to formulate problems of intentionality primarily in terms of logic and semantics rather than those of metaphysics and phenomenology. Dr. Aquila's effort to coordinate these approaches will make his book useful to students both of analytical philosophy of mind and also of phenomenology. (shrink)

Staged 2 different videotaped interviews with the same individual—a college instructor who spoke English with a European accent. In one of the interviews the instructor was warm and friendly, in the other, cold and distant. 118 undergraduates were asked to evaluate the instructor. Ss who saw the warm instructor rated his appearance, mannerisms, and accent as appealing, whereas those who saw the cold instructor rated these attributes as irritating. Results indicate that global evaluations of a person can induce altered evaluations (...) of the person's attributes, even when there is sufficient information to allow for independent assessments of them. Furthermore, Ss were unaware of this influence of global evaluations on ratings of attributes. In fact, Ss who saw the cold instructor actually believed that the direction of influence was opposite to the true direction. They reported that their dislike of the instructor had no effect on their rating of his attributes but that their dislike of his attributes had lowered their global evaluations of him. (shrink)

Charles Foster and Jonathan Herring are to be congratulated on their useful presentation of the roles played by concepts of personhood and identity in English medical law. 1 However, I fear that the project they have undertaken here is misconceived. It is an interesting and important misconception, which is widely shared in the literature on medical law and ethics; but a misconception it remains. The problem is this. What we call ‘the Law’ is in fact a complex assemblage of institutions, (...) rules, accredited persons, practices and systems. What it is not is a self-sufficient, integrated and self-interpreting system of doctrine. As such it does not have a clear structure which we can excavate and the idea that we can find concepts which explain and unify that structure at some deep level is thus quixotic. To approach ‘the Law’ in that way is to pursue a chimaera. We should instead... (shrink)

In ‘Salvaging the Concept of Nudge’ Yashar Saghai performs an important clarificatory task which certainly advances our philosophical and ethical understanding of nudges in public policy, and in healthcare ethics in particular.1 In this brief commentary I identify some issues which could usefully be taken forward in subsequent discussions.A central difficulty with ethical discussions of nudging is that insufficient care is taken to distinguish two morally important features of nudges. The first, which Saghai very properly concentrates upon, is the mechanism (...) of nudging. Nudges rely on psychological properties of human decision-makers as the way in which their intended effects are brought about. Much of the ethical concern with nudges focuses on just this. Whatever the motive of the nudger, or the objective of the nudge, or the ex ante or ex post ratification of the nudge by the nudge, operating through influence, impulse or non-rational features of the nudgee's decision-making is wrong. The nature of this wrongness can be spelled out in different ways, and which one of these we choose has important implications for the precise ethical argument …. (shrink)

128 female Ss were asked to make 4 judgments about a young woman after reading her "job application portfolio." Five characteristics of the young woman were manipulated orthogonally. Ss were asked to report how each of the 5 manipulated factors had influenced each of their judgments. "Observer Ss," who had access only to very impoverished descriptions of each of the 5 factors, were asked to predict how each of the factors would influence each of the judgments. Results show that S (...) reports about the effects of the factors on the judgments were in general highly inaccurate; observer predictions were extremely similar to S reports; for the single judgment for which Ss showed substantial accuracy, observer predictions were as accurate as S reports. Results indicate that whatever introspective access to cognitive processes may exist, it is not sufficient to produce generally accurate reports about such processes, nor even to produce reports that differ much from those of poorly informed outside observers.

The fitness of any evolutionary unit can be understood in terms of its two basic components: fecundity (reproduction) and viability (survival). Trade-offs between these fitness components drive the evolution of life-history traits in extant multicellular organisms. We argue that these trade-offs gain special significance during the transition from unicellular to multicellular life. In particular, the evolution of germ–soma specialization and the emergence of individuality at the cell group (or organism) level are also consequences of trade-offs between the two basic fitness (...) components, or so we argue using a multilevel selection approach. During the origin of multicellularity, we study how the group trade-offs between viability and fecundity are initially determined by the cell level trade-offs, but as the transition proceeds, the fitness trade-offs at the group level depart from those at the cell level. We predict that these trade-offs begin with concave curvature in single-celled organisms but become increasingly convex as group size increases in multicellular organisms. We argue that the increasingly convex curvature of the trade-off function is driven by the cost of reproduction which increases as group size increases. We consider aspects of the biology of the volvocine green algae – which contain both unicellular and multicellular members – to illustrate the principles and conclusions discussed. (shrink)

As its subtitle 'Skepticism, Individuality and Chastened Politics' indicates, this book is an exploration of and a largely favorable engagement with salient elements in the thinking of a theorist who is widely regarded as the greatest Anglophone political thinker and among the top rank of philosophical writers generally. In emphazing Hobbes's skepticism, Richard Flathman goes against the grain of much of the literature concerning Hobbes. The theme of individuality is more familiar, particularly from the celebrated writings on Hobbes by (...) Michael Oakeshott, but the idea of a chastened politics challenges the widely influential view that Hobbes was not only an authoritarian but an incipient or proto-totalitarian. (shrink)

Can any of us ever really be free? Do we follow the rules our society gives us because we want to, or because we are forced to? Discipline, Freedom, Resistance challenges the received wisdom that discipline and freedom are opposite and mutually exclusive. Though it is typically argued that a well-ordered liberal society must discipline its more unruly citizens to maintain freedom for all, Flathman shows how resistance to rules can mean more than criminals breaking laws. Resistance can also mean (...) political protest and political dialogues about what the rules can be. Discipline, Freedom, Resistance draws on Foucault's theories of the self to describe the inner discipline it takes to resist authority-declaring that individuals must sometimes resist forces that wish to destroy freedom, to ensure freedom.

Political argument and institutions in the UnitedKingdom have frequently been represented as the products of ablend of nationalistic conservatism, liberal individualism andsocialism, in which consensus has been prized over ideology. This situation changed, as the standard story has it, with therise of Thatcherism in the late 1970s, and again with the arrivalof Tony Blair's ``New Labour'' pragmatism in the late 1990s. Solidarity as an element of political discourse makes itsappearance in the UK late in the day. It has been most (...) stronglylinked to the Third Way debate, as framed most influentially inthe work of Prof. Anthony Giddens.In this paper we review the history and pre-history of the debateon solidarity in the UK, focussing mostly on its implications forwelfare state reform. In particular we discuss the proposals forthe long-term care of the Elderly issued by the Royal Commissionon long-term care in 1999. In this context we critically examinethe idea that solidarity is a new concept in British politicalculture, and that it is a concept which has real political ``bite''in the project of welfare reform. We examine this through aconsideration of Giddens's attempted synthesis of politicalargument and social theory. (shrink)
