Roy Clouser’s reply to my article on John Paul II’s 1998 encyclical Fides et Ratio is learned, engaging, clear--and, respectfully put, full of errors on many points regarding John Paul’s understanding of faith and reason.1 On this matter, he attacks a straw man. Indeed, at times I wondered whether Clouser and I had read the same encyclical. Despite this, however, let me underscore my genuine appreciation of Clouser for pressing me to be clearer on my view of the encyclical’s position (...) on faith and reason.My reply is organized in two parts. First, I argue that in FR faith is a form of knowing; John Paul II is not a rationalist; and the impact of the fall into sin on human reason is integral. Second, I defend the view of FR that a metaphysical theology is necessary in order to give an account of the intelligibility of the Christian revelation. Indeed, one of the biblical requirements for a “Scriptural philosophy” is a philosophy of a truly metaphysical range, according to John Paul. (shrink)

In this paper, I examine the four elements—universal sinfulness, natural sinfulness, inherited sinfulness, and Adamic sinfulness—of the doctrine of original sin in both the Reformed confessions, with particular attention to the Canons of Dort, and the Council of Trent’s definitive teaching on Original Sin. I give particular attention to the question regarding how all men are implicated in the sin of Adam. Realism and federalism will be analyzed as answers to this question. Even if a theological account is given that (...) justifies the claim that God may justly impute Adam’s sin to his posterity, that still leaves unanswered the question of unconditional negative reprobation, also called, preterition (praeteritio), namely, that God passes over some and not others. Does preterition jeopardize the Church’s call to evangelization? That question will need to be reconsidered briefly, and in conclusion, in light of the doctrine of divine election and its implications for the preaching and hence proclamation of the gospel.

I argue against Matthew Slater’s rejection of what he calls the grounding claim in his stable property cluster account of natural kinds. This claim states that the epistemic value of natural kinds depends on the existence of some ground to bind together a kind’s properties. Using two test cases from academic medicine, I show that grounds are genuinely explanatory of scientific epistemic practices and that the SPC account should not do without them in its philosophical analysis of natural kinds.

In this paper we develop a general representation theory for MV-algebras. We furnish the appropriate categorical background to study this problem. Our guide line is the theory of classifying topoi of coherent extensions of universal algebra theories. Our main result corresponds, in the case of MV-algebras and MV-chains, to the representation of commutative rings with unit as rings of global sections of sheaves of local rings. We prove that any MV-algebra is isomorphic to the MV-algebra of all global sections of (...) a sheaf of MV-chains on a compact topological space. This result is intimately related to McNaughton’s theorem, and we explain why our representation theorem can be viewed as a vast generalization of McNaughton’s theorem. In spite of the language used in this abstract, we have written this paper in the hope that it can be read by experts in MV-algebras but not in sheaf theory, and conversely. (shrink)

In “A new proof of the completeness of the Lukasiewicz axioms” Chang proved that any totally ordered MV-algebra A was isomorphic to the segment \}\) of a totally ordered l-group with strong unit A *. This was done by the simple intuitive idea of putting denumerable copies of A on top of each other. Moreover, he also show that any such group G can be recovered from its segment since \^*}\), establishing an equivalence of categories. In “Interpretation of AF C (...) *-algebras in Lukasiewicz sentential calculus” Mundici extended this result to arbitrary MV-algebras and l-groups with strong unit. He takes the representation of A as a sub-direct product of chains A i, and observes that \ where \. Then he let A * be the l-subgroup generated by A inside \. He proves that this idea works, and establish an equivalence of categories in a rather elaborate way by means of his concept of good sequences and its complicated arithmetics. In this note, essentially self-contained except for Chang’s result, we give a simple proof of this equivalence taking advantage directly of the arithmetics of the the product l-group \, avoiding entirely the notion of good sequence.

Four studies tested the hypothesis that a weaker belief in free will would be related to feeling less gratitude. In Studies 1a and 1b, a trait measure of free will belief was positively correlated with a measure of dispositional gratitude. In Study 2, participants whose free will belief was weakened (vs. unchanged or bolstered) reported feeling less grateful for events in their past. Study 3 used a laboratory induction of gratitude. Participants with an experimentally reduced (vs. increased) belief in free (...) will reported feeling less grateful for the favor. In Study 4, a reduced (vs. increased) belief in free will led to less gratitude in a hypothetical favor scenario. This effect was serially mediated by perceiving the benefactor as having less free will and therefore as being less sincerely motivated. These findings suggest that belief in free will is an important part of being able to feel gratitude. (shrink)

Research in zoos is an important scientific endeavor that requires several complex considerations in order to occur. Among those many considerations are the ethics involved in conducting zoo research. However, it is not always clear how zoo researchers should go about resolving any research ethics matters, even determining when some type of research ethics committee should be involved in those deliberations. Our paper attempts to provide some resolutions for these issues, namely in three sections: (1) a brief history of human (...) and animal research ethics, (2) general guidelines for zoo research ethics applications, and (3) theoretical, ethical dilemmas at the zoo. In each section, we consider pragmatic attempts to resolve any issues, as well as provide examples to illustrate our points. The primary focus of the paper is to facilitate consideration of the wide array of ethical factors any zoo researcher might encounter, as well as provide a basic set of ethical guidelines for zoo research. We also emphasize the importance of the welfare of the animals for all zoo research projects. (shrink)

We show the intimate relationship between McNaughton Theorem and the Chinese Remaindner Theorem for MV-algebras. We develop a very short and simple proof of McNaughton Theorem. The arguing is elementary and right out of the definitions. We exhibit the theorem as just an instance of the Chinese theorem. Since the variety of MV-algebras is arithmetic, the Chinese theorem holds for MV-algebras. However, to make this paper self-contained and entirely elementary, we include a simple proof of this theorem inspired in Ferraioli (...) and Lettieri (Math Logic Q 1:27–43, 2011). (shrink)

Modern zoos strive to educate visitors about zoo animals and their wild counterparts’ conservation needs while fostering appreciation for wildlife in general. This research review examines how zoos influence those who visit them. Much of the research to-date examines zoo visitors’ behaviors and perceptions in relation to specific exhibits, animals and/or programs. In general, visitors have more positive perceptions and behaviors about zoos, their animals and conservation initiatives the more they interact with animals, naturalistic exhibits, and zoo programming/staff. Furthermore, zoo (...) visitors are receptive to conservation messaging and initiatives at zoos, and are more likely to participate in on-site conservation opportunities as opposed to after their visits. The research also suggests that repeat visitors are even more inclined to seek out conservation efforts compared to those visiting zoos for the first time. While current research suggests that repeat-visitors are more likely to engage in conservation efforts, little is known about causal factors related to such findings, and almost no research exists to-date comparing the conservation efforts of visitors vs. non-visitors. This latter comparison will likely play a greater role in future zoo visitor research, since it poses one of the most important metrics for evaluating the specific effects visiting a zoo can have on people engaging in conservation efforts in general.

In this multi-faceted volume, Christian and other religiously committed theorists find themselves at an uneasy point in history—between premodernity, modernity, and postmodernity—where disciplines and methods, cultural and linguistic traditions, and religious commitments tangle and cross. Here, leading theorists explore the state of the art of the contemporary hermeneutical terrain. As they address the work of Gadamer, Ricoeur, and Derrida, the essays collected in this wide-ranging work engage key themes in philosophical hermeneutics, hermeneutics and religion, hermeneutics and the other arts, hermeneutics (...) and literature, and hermeneutics and ethics. Readers will find lively exchanges and reflections that meet the intellectual and philosophical challenges posed by hermeneutics at the crossroads. Contributors are Bruce Ellis Benson, Christina Bieber Lake, John D. Caputo, Eduardo J. Echeverria, Benne Faber, Norman Lillegard, Roger Lundin, Brian McCrea, James K. A. Smith, Michael VanderWeele, Kevin Vanhoozer, and Nicholas Wolterstorff. (shrink)

In spite of laws in many states regulating the nutritional content of foods and the availability of “junk food” and soda, a 2001 Surgeon General’s Report indicated that 15% to 20% of the nation’s children are overweight or obese. In areas that are predominately Hispanic and African American, the numbers rise to between 40% and 50%. Although there are continuing efforts to educate the adult population, many school systems and public health jurisdictions have had little impact on the rising numbers (...) of overweight and obese children. This session described the process of initiating a student-based, student driven approach to obesity, junk food, and diabetes and disease prevention.A need existed for a grassroots approach at the student level to raise awareness of increasing obesity rates and diabetes and other related diseases in the adolescent population.

Animals have always been important for human life due to the ecological, cultural and economic functions that they represent. This has allowed building several kinds of relationships that have promoted different emotions in human societies. The objective of this review was to identify the main emotions that humans show towards wildlife species and the impact of such emotions on animal populations’ management. We reviewed academic databases to identify previous studies on this topic worldwide. An analysis of the emotions on wildlife (...) and factors causing them is described here. We identified a controversy about these emotions. Large predators such as wolves, coyotes, bears, big felids, as well as reptiles such as snakes and geckos promote mainly anger, fear, and disgust. This is likely due to the perceptions, beliefs and experiences that societies have historically built around them. However, in some social groups these animals have promoted emotions such as happiness due to their values for people. Likewise, sadness is an emotion expressed for the threatening situations that animals are facing nowadays. Furthermore, we associated the conservation status of wildlife species identified in the study with human emotions to discuss their relevance for emerging conservation strategies, particularly focused on endangered species promoting ambiguous emotions in different social groups.

The compulsive habit model proposed by Everitt and Robbins has accumulated important empirical evidence. One of their proposals is the existence of an axis, on which each a person with a particular addiction can be located depending on the evolutionary moment of his/her addictive process. The objective of the present study is to contribute in addressing the identification of such axis, as few studies related to it have been published to date. To do so, the use/abuse of Information and Communication (...) Technologies (ICT) was quantified on an initial sample of 807 subjects. Questionnaires were also delivered to measure impulsivity, compulsivity and symptoms of prefrontal dysfunction. Evidence of the existence of the proposed axis was obtained by means of Machine Learning techniques, thus allowing the classification of each subject along the continuum. The present study provides preliminary evidence of the existence of the Impulsivity-Compulsivity axis, as well as an IT tool so that each patient that starts getting treatment for an addiction can be statistically classified as “impulsive” or “compulsive.” This would allow the matching of each person with the most appropriate treatment depending on his/her moment in the addiction/abuse process, thus facilitating the individualized design of each therapeutic process and a possible improvement of the results of the treatment.

Herman Bavinck (1854–1921), the Dutch master of dogmatic theology, wrote a systematic treatise in theological ethics. Bavinck is a theistic moral realist whose ethics is deontological and virtue centered. His realism—both ontological and epistemic—is reflected in his understanding of conscience and its relation to the objective moral law. Furthermore, this review article discusses issues in Christian anthropology, particularly the selfhood of the human person, the relation between nature and grace, creation and redemption, and philosophy and theology, and the distinction between (...) objective and subjective religion. It concludes with a brief reflection on Bavinck’s hermeneutics of renewal and reform in the continuity of the catholicity of the Reformed tradition. (shrink)
