In this article, I consider the famous Invisible Gardener Parable which aims to show that theism is not a viable theory because it can be endlessly amended to accommodate for prima facie disconfirming data. I point out that the parable fails to consider how tolerance for theory adjustment is relative to the perceived explanatory power of the theory. I also point out that naturalism is no less subject to adaptation than is theism. Thus, if endless adaptability constitutes an objection for (...) theism then it does so for naturalism as well.

In the history of Western thought, Christian theology was once considered to be 'the Queen of Sciences'. Today it has been marginalised by a prevailing scepticism. Randal Rauser confronts the problem of developing a public voice for the theologian as engaged in true theological science while not compromising the commitment to the Christian community of faith. This book posits a viable account of theological rationality, justification, and knowledge that avoids the twin pitfalls of modern rationalism and postmodern irrationalism. (...) Theology is freshly understood as a rigorous and rational truth-seeking discipline that seeks theoretical understanding of divine reality. Throughout the modern era the predominant epistemological position has been classical foundationalism, a position now widely rejected by philosophers and theologians alike. Philosophers recognize that it fails to achieve a plausible account of rationality, justification or knowledge, while theologians recognize the extent to which classical foundationalist strictures have distorted Christian doctrine. In its place many philosophers and theologians alike have adopted a nonfoundationalist epistemology, which is in turn often associated with a problematic alethic and metaphysical antirealism. Engaging with the ideas of key thinkers from Descartes, Locke, and Kant, to Bruce Marshall and Alvin Plantinga, Rauser provides an accessible and provocative survey of the theological terrain of the modern - and postmodern - era, arguing in favour of a return to a moderate foundationalism.

There has been considerable debate in the literature about the relative merits of information processing versus dynamical approaches to understanding cognitive processes. In this article, we explore the relationship between these two styles of explanation using a model agent evolved to solve a relational categorization task. Specifically, we separately analyze the operation of this agent using the mathematical tools of information theory and dynamical systems theory. Information-theoretic analysis reveals how task-relevant information flows through the system to be combined into a (...) categorization decision. Dynamical analysis reveals the key geometrical and temporal interrelationships underlying the categorization decision. Finally, we propose a framework for directly relating these two different styles of explanation and discuss the possible implications of our analysis for some of the ongoing debates in cognitive science.

The referential focus of this paper is not a hypothesis or theoretical point per se. Instead, it is the body of work (hereafter termed autopoietic theory) developed by Humberto Maturana and Francisco Varela. The intended audience is not a community of critical scholars per se. Instead it is the "community of interest" for whom autopoietic theory is at least an object of interest and at most an object of personal commitment. To the extent autopoietic theory has prospered and spread over (...) the last quarter century, it has often been a function of highly interactive, even personal, relationships among self-acknowledged adherents and those generally interested. Owing to the distribution of such correspondents across diverse disciplines, their cohesion as a "community" has been tenuous at best. I wish to step back from the usual scholarly perspective and use this venue to address what may be termed the pragmatics of autopoietic theory. The intention is to offer some sort of "state of the community" assessment, recommendations, and / or tips regarding: (a) autopoietic theory's documentary corpus; (b) discourse on autopoietic theory; and (c) applying the theory in the context of focused research. The goal is to help orient newcomers and provoke reflection among the "veterans.". (shrink)

The title of this paper represents a "trick question" of the sort an interlocutor might employ to solicit an answer which, if framed with specific regard to the question's implicatures, cannot fail to confirm that interlocutor's position or further his aims. The best-known query of this form is the cliched "Do you still beat your spouse?" To escape being trapped, the respondent must either (a) avoid answering or (b) point out and refute the implication(s) embedded in the question itself. In (...) practice, both options typically entail risk. Option (a) may violate the procedural form of the "language game" (cf. Wittgenstein, 1963) within which the question occurs, while option (b) may violate the thematic or orientational focus presumed or enacted in that language game. This paper is intended to outline a "trick question" (that of the title) which has over the years been a recurrent challenge slung at adherents of the theories which have brought us together here in Belo Horizonte. If the following text accomplishes my intentions, it will explain the challenge, assess our response(s) to date, and offer suggestions about what (if any) further action it may prudently motivate.

van Gelder argues that computational and dynamical systems are mathematically distinct kinds of systems. Although there are real experimental and theoretical differences between adopting a computational or dynamical perspective on cognition, and the dynamical approach has much to recommend it, the debate cannot be framed this rigorously. Instead, what is needed is careful study of concrete models to improve our intuitions.

This book evaluates the claim that in order to explore the changing social foundations of global power relations today, we need to include in our analysis an understanding of global civil society, particularly if we also wish to raise ethical questions about the changing political and institutional practices of transnational governance. The authors engage directly with the notion of global civil society in order to examines the ethical, social, and political conditions that make certain kinds of globalizing practices a reality (...) today. They explore and utilize the normative dimensions of the civil discourse to further debate about the meaning of citizenship in a world of multi-level governance, as well as the changing characteristics of political community and democracy. Bridging the normative concerns of political theorists with the historical and institutional focus of scholars of international relations and international political economy, this book will be of broad interest to students and researchers concerned with international relations, civil society, global governance and ethics.

Using 94 published empirical articles in academic journals as a data base, this paper provides a critical review of the methodology employed in the study of ethical beliefs and behavior of organizational members. The review revealed that full methodological detail was provided in less than one half of the articles. Further, the majority of empirical research articles expressed no concern for the reliability or validity of measures, were characterized by low response rates, used convenience samples, and did not offer a (...) theoretic framework, hypotheses, or a definition of ethics. Several recommendations, including a reviewer rating form addressing methodological decisions and inclusion of methodologists on the review panel, are offered to improve methodological rigor in published ethics research.

Engineering educators have long discussed the need to teach professional responsibility and the social context of engineering without adding to overcrowded curricula. One difficulty we face is the lack of appropriate teaching materials that can fit into existing courses. The PRiME (Professional Responsibility Modules for Engineering) Project (http://www.engr.utexas.edu/ethics/primeModules.cfm) described in this paper was initiated at the University of Texas, Austin to provide web-based modules that could be integrated into any undergraduate engineering class. Using HPL (How People Learn) theory, PRiME developed (...) and piloted four modules during the academic year 2004–2005. This article introduces the modules and the pilot, outlines the assessment process, analyzes the results, and describes how the modules are being revised in light of the initial assessment. In its first year of development and testing, PRiME made significant progress towards meeting its objectives. The PRiME Project can strengthen engineering education by providing faculty with an effective system for engaging students in learning about professional responsibility. (shrink)

A handy guide to the major figures and issues in Christian philosophy from Augustine to the present.This volume covers a broad historical sweep and takes into account those non-Christian philosophers that have had a great impact on the Christian tradition. However, it concentrates on the issues that perplex Christian philosophers as they seek to think through their faith in a philosophical way and their philosophical beliefs in the light of their faith. Examples of the topics discussed are the question of (...) whether and how God knows the future, whether we actually know that God exists, and what Athens has to do with Jerusalem. The leaders of the recent revival of Christian analytic philosophy, especially Alvin Plantinga, Nicholas Wolterstorff, William Alston, and Robert Adams are also included. (shrink)

Over the last few decades, several scientific studies have attempted to measure the effectiveness of prayer in bringing about healing. But can we really test the therapeutic effect of prayer in the same way that we test conventional medicinal treatments? On the contrary, in this article, I present three arguments in support of the conclusion that such attempts to measure the effectiveness of prayer are based on flawed assumptions. One implication of this is that the failure to draw a positive (...) statistical relationship between prayer and healing does not constitute good evidence against the value of prayer.Export citation.

A comprehensive formal system is developed that amalgamates the operational and the realistic approaches to quantum mechanics. In this formalism, for example, a sharp distinction is made between events, operational propositions, and the properties of physical systems.

Piron's axioms for a realistically interpreted quantum mechanics are analyzed in detail within the context of a formal mathematical structure expressed in the conventional set-theoretic idiom of mathematics. As a result, some of the serious misconceptions that have encouraged recent criticisms of Piron's axioms are exposed.

In orthodox quantum mechanics, it has virtually become the custom to identify properties of a physical system with operationally testable propositions about the system. The causes and consequences of this practice are explored mathematically in this paper. Among other things, it is found that such an identification imposes severe constraints on the admissible states of the physical system.

This paper reviews the fate of the central ideas behind the complementary learning systems (CLS) framework as originally articulated in McClelland, McNaughton, and O’Reilly (1995). This framework explains why the brain requires two differentially specialized learning and memory systems, and it nicely specifies their central properties (i.e., the hippocampus as a sparse, pattern-separated system for rapidly learning episodic memories, and the neocortex as a distributed, overlapping system for gradually integrating across episodes to extract latent semantic structure). We review the application (...) of the CLS framework to a range of important topics, including the following: the basic neural processes of hippocampal memory encoding and recall, conjunctive encoding, human recognition memory, consolidation of initial hippocampal learning in cortex, dynamic modulation of encoding versus recall, and the synergistic interactions between hippocampus and neocortex. Overall, the CLS framework remains a vital theoretical force in the field, with the empirical data over the past 15 years generally confirming its key principles. (shrink)

This chapter argues that the objection that Socrates makes against diviners, poets, and rhapsodies having knowledge is an example of what has come to be known as an opacity objection: that is, some aspect of what would be required for them to know is unrecognised by them. This chapter contends that the opacity is of a different kind than what contemporary epistemologists have considered, and claims that Socrates’ specific version should have a place in contemporary theory of knowledge.

Late in 1990, the Center for the Study of Ethics in the Professions at Illinois Institute of Technology (lIT) received a grant of more than $200,000 from the National Science Foundation to try a campus-wide approach to integrating professional ethics into its technical curriculum.! Enough has now been accomplished to draw some tentative conclusions. I am the grant's principal investigator. In this paper, I shall describe what we at lIT did, what we learned, and what others, especially philosophers, can learn (...) from us. We set out to develop an approach that others could profitably adopt. I believe that we succeeded. (shrink)

Background: Electroconvulsive therapy is one of the most effective treatments for major depressive disorder. Recently, there has been increasing attention to evaluate the effect of ECT on resting-state functional magnetic resonance imaging. This study aims to compare rs-fMRI of depressive disorder patients with healthy participants, investigate whether pre-ECT dynamic functional network connectivity network estimated from patients rs-fMRI is associated with an eventual ECT outcome, and explore the effect of ECT on brain network states.Method: Resting-state functional magnetic resonance imaging data were (...) collected from 119 patients with depression or depressive disorder, and 61 healthy participants, with an age mean of 52.25 years old. The pre-ECT and post-ECT Hamilton Depression Rating Scale were 25.59 ± 6.14 and 11.48 ± 9.07, respectively. Twenty-four independent components from default mode and cognitive control network were extracted, using group-independent component analysis from pre-ECT and post-ECT rs-fMRI. Then, the sliding window approach was used to estimate the pre-and post-ECT dFNC of each subject. Next, k-means clustering was separately applied to pre-ECT dFNC and post-ECT dFNC to assess three distinct states from each participant. We calculated the amount of time each subject spends in each state, which is called “occupancy rate” or OCR. Next, we compared OCR values between HC and DEP participants. We also calculated the partial correlation between pre-ECT OCRs and HDRS change while controlling for age, gender, and site. Finally, we evaluated the effectiveness of ECT by comparing pre- and post-ECT OCR of DEP and HC participants.Results: The main findings include depressive disorder patients had significantly lower OCR values than the HC group in state 2, where connectivity between cognitive control network and default mode network was relatively higher than other states, Pre-ECT OCR of state, with more negative connectivity between CCN and DMN components, is linked with the HDRS changes. This means that those DEP patients who spent less time in this state showed more HDRS change, and The post-ECT OCR analysis suggested that ECT increased the amount of time DEP patients spent in state 2.Conclusion: Our finding suggests that dynamic functional network connectivity features, estimated from CCN and DMN, show promise as a predictive biomarker of the ECT outcome of DEP patients. Also, this study identifies a possible underlying mechanism associated with the ECT effect on DEP patients. (shrink)

The rise of the phenomenon of virtue ethics in recent years has increased at a rapid pace. Such an explosion carries with it a number of great possibilities, as well as risks. This volume has been written to contribute a multi-faceted perspective to the current conversation about virtue. Among many other thought-provoking questions, the collection addresses the following: What are the virtues, and how are they enumerated? What are the internal problems among ethicists, and what are the objections and replies (...) to contemporary virtue ethics? Additionally, the practical implications following from the answers to these questions are discussed in new and fascinating research. Fundamental concepts such as teleology and eudaimonism are addressed from both a historical and dialectical approach. This tome will contribute not only to providing further clarity to the current horizons in virtue ethics, but also to the practical conclusion following from the study: to challenge the reader toward a greater pursuit of the virtuous life.

Compared to our understanding of positive prediction error signals occurring due to unexpected reward outcomes, less is known about the neural circuitry in humans that drives negative prediction errors during omission of expected rewards. While classical learning theories such as Rescorla–Wagner or temporal difference learning suggest that both types of prediction errors result from a simple subtraction, there has been recent evidence suggesting that different brain regions provide input to dopamine neurons which contributes to specific components of this prediction error (...) computation. Here, we focus on the brain regions responding to negative prediction error signals, which has been well-established in animal studies to involve a distinct pathway through the lateral habenula. We examine the activity of this pathway in humans, using a conditioned inhibition paradigm with high-resolution functional MRI. First, participants learned to associate a sensory stimulus with reward delivery. Then, reward delivery was omitted whenever this stimulus was presented simultaneously with a different sensory stimulus, the conditioned inhibitor. Both reward presentation and the reward-predictive cue activated midbrain dopamine regions, insula and orbitofrontal cortex. While we found significant activity at an uncorrected threshold for the CI in the habenula, consistent with our predictions, it did not survive correction for multiple comparisons and awaits further replication. Additionally, the pallidum and putamen regions of the basal ganglia showed modulations of activity for the inhibitor that did not survive the corrected threshold. (shrink)
