This is a new edition of Joseph Fletcher's 1966 work that ignited a firestorm of controversy at the time of its publication.

Taking a critical look at some of the recent controls over human life, health, and death, Fletcher draws a vivid picture of contemporary biological needs and ethical responsibility. Genetic engineering, fetal research, abortion, suicide, human experimentation, infanticide, and euthanasia are some of the issues explored.

It is generally agreed that the method of explication consists in replacing a vague, presystematic notion (the explicandum) with a precise notion (the explicatum) formulated in a systematic context. However, Carnap and others who have used this and related terms appear to hold inconsistent views as to what constitutes an adequate explication. The central feature of the present explication of 'explication' is the correspondence condition: permitting the explicandum to deviate from some established "ordinary-language" conventions but, at the same time, requiring (...) that the explicatum correspond (via an effective translation) to the chosen "definitive intension" of the explicandum. (In effect, the first stages of an explication provide an informal characterization of a vague and possibly inconsistent language convention.) The present account of explication contrasts sharply with that sketched by Quine in Word and Object (although Quine accepts a correspondence condition of a sort). The terms `explication 1 ' and `explication 2 ' are used to indicate these quite different senses of the term. In Kaplan's terminology, explication 1 is intended to remedy "external vagueness" while explication 2 is intended to remedy "internal vagueness.". (shrink)

It is argued that current attempts to model human learning behavior commonly fail on one of two counts: either the model assumptions are artificially restricted so as to permit the application of mathematical techniques in deriving their consequences, or else the required complex assumptions are imbedded in computer programs whose technical details obscure the theoretical content of the model. The first failing is characteristic of so-called mathematical models of learning, while the second is characteristic of computer simulation models. An approach (...) to model building which avoids both these failings is presented under the title of a black-box theory of learning. This method permits the statement of assumptions of any desired complexity in a language which clearly exhibits their theoretical content.Section II of the paper is devoted to the problem of testing and comparing alternative learning theories. The policy advocated is to abandon attempts at hypothesis testing. It is argued that, in general, we not only lack sufficient data and sufficiently powerful techniques to test hypotheses, but that the truth of a model is not really the issue of basic interest. A given model may be true in the sense that on the basis of available evidence we cannot statistically reject it, but not interesting in the sense that it provides little information about the processes underlying behavior. Rather, we should accept or reject models on the basis of how much information they provide about the way in which subjects respond to environmental structure. This attitude toward model testing is made precise by introducing a formal measure of the information content of a model. Finally, it is argued that the statistical concept of degrees-of-freedom is misleading when used in the context of model testing and should be replaced by a measure of the information absorbed from the data in estimating parameters.

Offering an alternative to the theories of Skinner and other behaviorists, Rychlak draws upon recent research to support his belief that people can alter the grounds for their behavior and assume greater responsibility for it.

A technological revolution with first order implications is undeniable and underway. That is the permeation of society by computers and telecommunications technology. For western society, committed to a social, economic, and value structure premised upon an industrial society, the move to an information society is more than disruptive; it is transformational. Current changes are so rapidly paced in relation to business planning that it creates major challenges and opportunities to reach out, influence, and guide the change.The telematics revolution will affect (...) every aspect of our society since it will affect every aspect of our world which involves the generation, production, storage, or handling of information. Many ethical issues are touched upon. To sum them up, the new immorality is to choose to act in ignorance of future consequences. (shrink)

Mathematical expressions for the entropyS, the average information gained per trial (Ī) from information theory, and the de Broglie cyclical action integralA from his reinterpretation of wave mechanics are shown to be similar. The importance of this observation in our understanding ofS andĪ is considered. Furthermore, the similarity in the mathematical form of these functions indicates a possible route to further interpretation of de Broglie'sA and the nature of his “hidden thermostat.”.

Setting optimal significance levels that minimize Type I and Type II errors allows for more transparent and well‐considered statistical decision making compared to the traditional α = 0.05 significance level. We use the optimal α approach to re‐assess conclusions reached by three recently published tests of the pace‐of‐life syndrome hypothesis, which attempts to unify occurrences of different physiological, behavioral, and life history characteristics under one theory, over different scales of biological organization. While some of the conclusions reached using optimal α (...) were consistent to those previously reported using the traditional α = 0.05 threshold, opposing conclusions were also frequently reached. The optimal α approach reduced probabilities of Type I and Type II errors, and ensured statistical significance was associated with biological relevance. Biologists should seriously consider their choice of α when conducting null hypothesis significance tests, as there are serious disadvantages with consistent reliance on the traditional but arbitrary α = 0.05 significance level.

The distinction between explanation and prediction has received much attention in recent literature, but the equally important distinction between explanation and description (or between prediction and description) remains blurred. This latter distinction is particularly important in the social sciences, where probabilistic models (or theories) often play dual roles as explanatory and descriptive devices. The distinction between explanation (or prediction) and description is explicated in the present paper in terms of information theory. The explanatory (or predictive) power of a probabilistic model (...) is identified with information taken from (or transmitted by) the environment (e.g., the independent, experimentally manipulated variables), while the descriptive power of a model reflects additional information taken from (or transmitted by) the data. Although information is usually transmitted by the data in the process of estimating parameters, it turns out that the number of free parameters is not a reliable index of transmitted information. Thus, the common practice of treating parameters as degrees-of-freedom in testing probabilistic models is questionable. Finally, this information-theoretic analysis of explanation, prediction, and description suggests ways of resolving some recent controversies surrounding the pragmatic aspects of explanation and the so-called structural identity thesis.

The aim of this paper is twofold: first to sketch a framework for classifying a wide range of conceptions of scientific objectivity and second to present and defend a conception of scientific objectivity that fills a neglected niche in the resulting hierarchy of viewpoints. Roughly speaking, the proposed ideal of scientific objectivity is effectiveness in the informal but technical sense of an effective method. Science progresses when "higher levels of communicative discourse" are reached by transforming subjective judgments regarding the generation (...) and reduction of data or the testing of theories into objective decision procedures that are automatic or mechanical.

Using an experiment with corporate financial managers, we find that when red flags are present in the financial statements under their review, managers identify those red flags and, in turn, have greater concerns over earnings quality. In addition, when pressure to meet a financial target is high, managers are more concerned about earnings quality when red flags are present. We also document that when red flags are present, managers are more likely to report both internally to their CEO and, if (...) their concerns are not resolved internally, externally to their auditor. Pressure to meet a financial target increases the likelihood managers report internally, but decreases their likelihood of reporting externally when red flags are present. Additional analyses document reporting differences between CFOs and controllers, and examine the important roles that short-term personal costs, job tenure, and a non-accounting background play in the ethical dilemma managers face when deciding whether to report externally.

It remains the case that economic ethics is still an underdeveloped specialization within the discipline of religious ethics. Contemporary commentators have lamented the still emergent status of economic ethics and recently some have begun to point out new directions for this area of moral reflection. Part of the problem has been the historical fact that not many religious ethicists have taken the time to acquire the required specialization competence in economics, economic theory, and history. Religion and Economic Ethics presents nineteen (...) readings that illuminate the economic side of religious ethics. Contributions include: Economic Justice and the Common-wealth of Peoples, by Douglas Sturm; Economic Systems and the Sacramental Imagination, by Joseph La Barge; Common Moral and Religious Grounds for Uncommon Economic Times, by James F. Smurl; Liberation Theology and the Vatican, by Arthur F. McGovern. Co-published with the College Theology Society. (shrink)

Based on the idea that God is all around us, the author provides a simple answer to one of history's most complex questions.

This paper contrasts two information-theoretic approaches to statistical explanation: namely, (1) an analysis, which originated in my earlier research on problems of testing stochastic models of learning, based on an entropy-like measure of expected transmitted-information (and here referred to as the Expected-Information Model), and (2) the analysis, which was proposed by James Greeno (and which is closely related to Wesley Salmon's Statistical Relevance Model), based on the information-transmitted-by-a-system. The substantial differences between these analyses can be traced to the following basic (...) difference. On Greeno's view, the essence of explanation lies in the relevance relations expressed by the conditional probabilities that relate the explanans variables to the explanandum variables; on my view, in contrast, the essence of explanation lies in theories viewed as hypothetical structures which deductively entail conditional probability distributions linking the explanans variables and the explanandum variables. The explanatory power of a stochastic theory is identified with information (regarding the values of explanandum variables) which is "absorbed from" the explanans variables. While other information which is "absorbed from" the explanandum variables (through the process of parameter estimation, for example) reflects descriptive power of the theory. I prove that Greeno's measure of transmitted information is a limiting special case of the E-I model, but that the former, unlike the latter, makes no distinction between explanatory power and descriptive power.

This essay explores and interprets two texts from Parochial and Plain Sermons in light of Newman’s understanding of religious imagination—specifically, the act of realization. Both texts suggest that for Newman, realization is a type of self-appropriation by which a fact or an object is assimilated . One sermon concerns the Passion, the other the Resurrection. He indicates that when the object of the imagination is Christ, realization comes about through meditation on Scripture, and produces a stronger or weaker vision of (...) Jesus in the soul based on one’s personal dispositions. It is often employed when the mind engages in conflicting ideas, such as Christ as both God and man. (shrink)
