Raymond Callahan's lively study exposes the alarming lengths to which school administrators went, particularly in the period from 1910 to 1930, in sacrificing educational goals to the demands of business procedures.

This is a comprehensive study of the English word 'or', and the logical operators variously proposed to present its meaning. Although there are indisputably disjunctive uses of or in English, it is a mistake to suppose that logical disjunction represents its core meaning. 'Or' is descended from the Anglo-Saxon word meaning second, a form which survives in such expressions as "every other day." Its disjunctive uses arise through metalinguistic applications of an intermediate adverbial meaning which is conjunctive rather than disjunctive (...) in character. These conjunctive uses have puzzled philosophers and logicians, and have been discussed extensively under such headings as "free choice permission." This study examines the textbook myths that have clouded our understanding of how or and other "logical" vocabulary comes to have something approaching its logical meaning in natural languages. It considers the various historical conceptions of disjunction and its place in logic from the Stoics to the present day. (shrink)

There is a well-entrenched schism on the frequency, intensity, and evolutionary significance of warfare among hunter-gatherers compared with large-scale societies. To simplify, Rousseauians argue that warfare among prehistoric and contemporary hunter-gatherers was nearly absent and, if present, was a late cultural invention. In contrast, so-called Hobbesians argue that violence was relatively common but variable among hunter-gatherers. To defend their views, Rousseauians resort to a variety of tactics to diminish the apparent frequency and intensity of hunter-gatherer warfare. These tactics include redefining (...) war, censoring ethnographic accounts of warfare in comparative analyses, misconstruing archaeological evidence, and claiming that outside contact inflates the intensity of warfare among hunter-gatherers. These tactics are subject to critical analysis and are mostly found to be wanting. Furthermore, Hobbesians with empirical data have already established that the frequency and intensity of hunter-gatherer warfare is greater compared with large-scale societies even though horticultural societies engage in warfare more intensively than hunter-gatherers. In the end I argue that although war is a primitive trait we may share with chimpanzees and/or our last common ancestor, the ability of hunter-gatherer bands to live peaceably with their neighbors, even though war may occur, is a derived trait that fundamentally distinguishes us socially and politically from chimpanzee societies. It is a point often lost in these debates. (shrink)

Considerable research on helpers-at-the-nest demonstrates the positive effects of firstborn daughters on a mother’s reproductive success and the survival of her children compared with women who have firstborn sons. This research is largely restricted to agricultural settings. In the present study we ask: “Does ‘daughter first’ improve mothers’ reproductive success in a hunting and gathering context?” Through an analysis of 84 postreproductive women in this population we find that the sex of the first- or second-born child has no effect on (...) a mother’s fertility or the survival of her offspring. We conclude that specific environmental and economic factors underlay the helpers-at-the-nest phenomenon. (shrink)

Tallis brings his familiar erudition and insight to this most intriguing and important philosophical question - the nature of our freedom - one that impacts most directly on our lives and takes us to the heart of what we are.

Distinguished French sociologist Raymond Boudon presents here a critical theory history of the concept of ideology. His highly original and lucidly argued study addresses the core question of any account of ideology. How do individuals come to adhere to false or apparently irrational beliefs, and how do such beliefs become collectively accepted as true? Boudon begins by providing an exhaustive and subtle critique of sociological explanations of ideology from early conceptions to its current usage in the works of Barthes, (...) Foucault, Habermas, Sartre, and others. He then offers his own interpretation of the origins and emergence of ideological beliefs. In opposition to those views which associate ideology with irrationalism, Boudon shows that ideologies are a natural ingredient of social life; he develops a rationalist theory that helps to explain why certain ideas are believed by individuals and thereby effective in the social world. Finally, he examines case studies of two modern-day ideologies--developmentalism and Third Worldism. Moving easily across disciplinary boundaries, Boudon's provocative contribution to a subject of growing significance will be of great interest to scholars in sociology and social theory, as well as philosophy, political science, and development studies.

Grounded in Bandura’s social cognitive theory of moral thought and action, we develop a conceptual model linking supervisors’ perceptions of organizational injustice and abusive supervision with moral disengagement mechanisms acting as the underlying process. Specifically, we elaborate why and how supervisors’ experiences of each type of injustice would trigger their adoption of distinctive moral disengagement mechanisms, which in turn lead to their abusive supervisory conduct. The present conceptual model sheds new light on linking organizational injustice to abusive supervision from a (...) moral perspective. In addition, it also provides important theoretical and managerial implications to our current understanding of why and how abusive supervision happens. (shrink)

Kurt Godel, the greatest logician of our time, startled the world of mathematics in 1931 with his Theorem of Undecidability, which showed that some statements in mathematics are inherently "undecidable." His work on the completeness of logic, the incompleteness of number theory, and the consistency of the axiom of choice and the continuum theory brought him further worldwide fame. In this introductory volume, Raymond Smullyan, himself a well-known logician, guides the reader through the fascinating world of Godel's incompleteness theorems. (...) The level of presentation is suitable for anyone with a basic acquaintance with mathematical logic. As a clear, concise introduction to a difficult but essential subject, the book will appeal to mathematicians, philosophers, and computer scientists. (shrink)

What is privacy? Why do we need it and value it so much? This Very Short Introduction examines why privacy has become one of the most important topics in contemporary society. Considering issues of privacy in relation to security, the protection of personal data, and the paparazzi, its implications are wide-ranging and affect us all.

They may not have happened yet; but they are on the way. Reports, conference talks and exhibitions have provided windows into our possible and probable futures. As our ways of living have changed dramatically over the last 20 or so years, so might we expect even more such changes in the next couple of decades? But what changes might be in the offing and how should we as citizens, students, educators, ethicists and concerned individuals deal with them?Not all of the (...) prospects that are in today’s news will emerge and become consolidated as way-of-life changing mediators. Some of the developments that are on the cards may be difficult to scale-up, produce or manufacture. Others will fall by the wayside because of cost issues, lack of financial backing or poor marketing. And there are always issues of safety, real or imagined, to be dealt with as well as the ethical issues entailed. Also it must be appreciated that there is a category difference between the production of a “tool” and the “ .. (shrink)

The logic of partial terms (LPT) is a variety of negative free logic in which functions, as well as predicates, are strict. A companion paper focused on nonconstructive LPTwith definite descriptions, called LPD, and laid the foundation for tableaux systems by defining the concept of an LPDmodel system and establishing Hintikka's Lemma, from which the strong completeness of the corresponding tableaux system readily follows. The present paper utilizes the tableaux system in establishing an Extended Joint Consistency Theorem for LPDthat incorporates (...) the Robinson Joint Consistency Theorem and the Craig-Lyndon Interpolation Lemma. The method of proof is similar to that originally used in establishing the Extended Joint Consistency Theorem for positive free logic. Proof of the Craig-Lyndon Interpolation Lemma for formulas possibly having free variables is readily had in LPTand its intuitionistic counterpart. The paper concludes with a brief discussion of the theory of definitions in LPD. (shrink)

ABSTRACTTreating conditionals as probabilistic statements has been referred to as a defining feature of the “new paradigm” in cognitive psychology. Doing so is attractive for several reasons, but it complicates the problem of assessing the merits of conditional arguments. We consider several variables that relate to judging the persuasiveness of conditional arguments with uncertain premises. We also explore ways of judging the consistency of people's beliefs as represented by components of conditional arguments. Experimental results provide evidence that inconsistencies in beliefs (...) are more prevalent if the arguments’ components are spatially and temporally dispersed than if they are contiguous in space and time. This supports the idea that assuring the consistency among even a small number of beliefs is difficult to do, especially if the beliefs in question are not brought into consciousness at the same time; but consistency can be enhanced when beliefs are considered simultaneously or nea...

Peter French has argued that conglomerate collectivities such as business corporations are moral persons and that aggregate collectivities such as lynch mobs are not. Two arguments are advanced to show that French's claim is flawed. First, the distinction between aggregates and conglomerates is, at best, a distinction of degree, not kind. Moreover, some aggregates show evidence of moral personhood. Second, French's criterion for distinguishing aggregates and conglomerates is based on inadequate grounds. Application of the criterion to specific cases requires an (...) additional judgment of a pragmatic nature which undermines any attempt to demonstrate French's thesis that actual conglomerates are moral persons and aggregates are not. Thus, French's theory is seriously lacking both empirical basis and empirical relevance. (shrink)

Neither employer expectations of loyalty, nor good treatment of employees by employers, nor employee appreciation of employers, nor the duty of nonmaleficence, nor the intention to be loyal, nor the duty not to act disloyally provide a basis for a moral or ethical duty of employee loyalty. However, in addition to the law, a pledge to be loyal can obligate one to be loyal. But if the specific content of such a pledge is unstated, the conduct required by the pledge (...) may be indefinite. Moreover, the content and implications of loyalty are fluid, varying from context to context. Consequently, there is only a limited basis for the thesis that employees owe loyalty to their employers.

The family, like so many other modern institutions, often looks more like an arena of competing wills than an ordered life in common. If we hope, therefore, to protect the special role that parents should have in relation to their children, and that the family in general should have in relation to its members, we will need a much more developed account of the goods that are at stake and why we think they are important enough to require authority, even (...) when members of the family oppose the decisions of that authority. This essay develops an older account of authority, one rooted in the thought of Aristotle and St. Thomas Aquinas, and applies this account to our present difficulties concerning the authority of the family over its members in health care decision making.

The Argument from Uncertainty in the abortion debate is the argument that because the moral status of the fetus is uncertain, abortion policies should afford it maximum protection in order to avoid doing very great evil. Three versions of the argument are developed, and each is based upon an unfounded assumption of a burden of proof in the abortion debate. Each is found to make an unwarranted assumption, or to beg the question, and each fails to provide reasonable support for (...) its conclusion. (shrink)

The concept of liquid modernity proposed by Zygmunt Bauman suggests a rapidly changing order that undermines all notions of durability. It implies a sense of rootlessness to all forms of social construction. In the field of development, such a concept challenges the meaning of modernization as an effort to establish long lasting structures. By applying this concept to development, it is possible to address the nuances of social change in terms of the interplay between the solid and liquid aspects of (...) modernization. (shrink)

In this study meal sharing is used as a way of quantifying food transfers between households. Traditional food-sharing studies measure the flow of resources between households. Meal sharing, in contrast, measures food consumption acts according to whether one is a host or a guest in the household as well as the movement of people between households in the context of food consumption. Our goal is to test a number of evolutionary models of food transfers, but first we argue that before (...) one tests models of who should receive food one must understand the adaptiveness of food transfers. For the Ye’kwana, economies of scale in food processing and preparation appear to set the stage for the utility of meal sharing. Evolutionary models of meal sharing, such as kin selection and reciprocal altruism, are evaluated along with non-evolutionary models, such as egalitarian exchange and residential propinquity. In addition, a modified measure of exchange balance—proportional balance—is developed. Reciprocal altruism is shown to be the strongest predictor of exchange intensity and balance. (shrink)

This essay first develops St. Thomas Aquinas’s appropriation of Aristotle's hylomorphic account of human nature by considering Aquinas’s commentary on the De anima and Aquinas's own mature account of human nature in the Summa Theologiae. It is then made clear how a series of problems arises for Aquinas’s position based on whether we emphasize body/soul unity or the special status of the intellectual soul, taking as the central difficulty the status of the disembodied soul between death and resurrection. In conclusion (...) a radical solution to this difficulty is proposed based on a reconsideration of the material element of human nature. (shrink)

This essay develops the foundations of a Thomistic ethics of inquiry by proposing an account of 'consilium' (or practical deliberation) that is essentially social. This account in turn has three important implications. First, the moral knowledge available to us prior to the workings of 'consilium' is too vague to ground anything approaching substantive moral conclusions (the content of 'synderesis' is significantly limited). Second, if the apprehension of all but the very highest moral truths depends on a series of deliberative relationships, (...) the nature and development of those relationships must be a central task of Thomistic ethics. Third, the workings of 'consilium' itself, pointing us toward a particular kind of moral community, can ground the nature and content of Thomistic ethics as an ethics of inquiry. (shrink)

The core entities of computer science include formal languages, spec-ifications, models, programs, implementations, semantic theories, type inference systems, abstract and physical machines. While there are conceptual questions concerning their nature, and in particular ontological ones (Turner 2018), our main focus here will be on the relationships between them. These relationships have an extensional aspect that articulates the propositional connection between the two entities, and an intentional one that fixes the direction of governance. An analysis of these two aspects will drive (...) our investigation; an investigation that will touch upon some of the central concerns of the philosophy of computer science (Turner 2017). (shrink)

"Has any individual ever shaped his own civilization more thoroughly than Confucius? Certainly no other world figure has ever been presented as more of an exemplar to his countrymen. Yet what we know about the man himself is vague and shadowy, and the sayings attributed to him may seem obscure to the Westerner. Raymond Dawson addresses these paradoxes. Taking as a model the Chinese tradition of commentary on classical texts--in this case the Analects, the oldest and most reliable Confucian (...) text--he finds a body of thought whose expression does seem to reflect the views and aspirations of a recognizable person. He shows how the separate components of the Master's thought cohere into a distinct social, ethical, and intellectual system. Dawson elucidates the contemporary applicability of the sayings as well as the strength of their influence throughout the two and a half millennia of their currency, even in a China that has formally rejected them."-- provided by publisher.

Using a conceptual model consisting of three intersecting spheres of concern (environmental protection, human needs provision, and economic welfare) central to most environmental issues, we map six major Christian traditions of thought. Our purpose is to highlight the complementarities among these diverse responses in order to inform a more holistic Christian environmentalism founded on one or more of the major tenets of each of the six core traditions. Our approach also incorporates major premises of at least the more moderate versions (...) of biocentrism, ecocentrism, and anthropocentrism. We label this holistic approach “cosmocentrism” and use it as the basis for a preliminary description of the notion of “pluralistic stewardship.” We argue that only such holistic environmental perspectives, where societal needs are more directly coupled with environmental protection, and a pluralism of worldviews are acknowledged as potentially contributing to such efforts are capable of successfully addressing the complex issues we face today. We note that, at the international level in particular, Christian thought and secular environmentalism already have been moving in such a direction. (shrink)

The Logic of Partial Terms LPT is a strict negative free logic that provides an economical framework for developing many traditional mathematical theories having partial functions. In these traditional theories, all functions and predicates are strict. For example, if a unary function (predicate) is applied to an undefined argument, the result is undefined (respectively, false). On the other hand, every practical programming language incorporates at least one nonstrict or lazy construct, such as the if-then-else, but nonstrict functions cannot be either (...) primitive or introduced in definitional extensions in LPT. Consequently, lazy programming language constructs do not fit the traditional mathematical mold inherent in LPT. A nonstrict (positive free) logic is required to handle nonstrict functions and predicates. Previously developed nonstrict logics are not fully satisfactory because they are verbose in describing strict functions (which predominate in many programming languages), and some logicians find their semantics philosophically unpalatable. The newly developed Lazy Logic of Partial Terms LL is as concise as LPT in describing strict functions and predicates, and strict and nonstrict functions and predicates can be introduced in definitional extensions of traditional mathematical theories. LL is "built on top of" LPT, and, like LPT, admits only one domain in the semantics. In the semantics, for the case of a nonstrict unary function h in an LL theory T, we have $\models_T h(\perp) = y \longleftrightarrow \forall x(h(x) = y)$ , where $\perp$ is a canonical undefined term. Correspondingly, in the axiomatization, the "indifference" (to the value of the argument) axiom $h(\perp) = y \longleftrightarrow \forall x(h(x) = y)$ guarantees a proper fit with the semantics. The price paid for LL's naturalness is that it is tailored for describing a specific area of computer science, program specification and verification, possibly limiting its role in explicating classical mathematical and philosophical subjects.

Jacques Maritain claims in the opening pages of Scholasticism and Politics that his distinction between individuality and personality is a universal one, and is found prominently, for example, in classical Hindu philosophy. After explaining Maritain's use of these terms, and their importance in Scholasticism and Politics, I consider the principle Upanishads and The Bhagavad Gita in order to see how true Maritain's claim might be, and what importance this might have for politics.

This paper develops some foundations for an Aristotelian ethics of the built environment by combining the formal elements of Aristotelian justice with the design theory of Christopher Alexander. The resulting ordered set of human actions and their corresponding built environments require social deliberation about the integration of activities. This deliberation is required at all levels of human action, is characterized by local and step-wise decision making, and in important ways makes it possible for us to know if and how we (...) are harming others. On the political level this is embodied in the “public square,” whose essential purpose as integrative and moral-epistemological has deep and provocative implications for our built environment. For example, walkable human communities should be the default ethical choice for our built environment. I conclude by discussing a two-fold challenge to the New Urbanism movement for the light this sheds on the overall argument. (shrink)
